mc75172b mc75174b http://onsemi.com 8 applications information description the mc75172b and mc75174b are differential line drivers designed to comply with eia485 standard (april 1983) for use in balanced digital multipoint systems containing multiple drivers. the drivers also comply with eia422a and ccitt recommendations v.11 and x.27. the drivers meet the eia485 requirement for protection from damage in the event that two or more drivers attempt to transmit data simultaneously on the same cable. data rates in excess of 10 mbps are possible, depending on the cable length and cable characteristics. a single power supply, 5.0 v, 5%, is required at a nominal current of 60 ma, plus load currents. outputs each output (when active) will be a low or a high voltage, which depends on the input state and the load current (see table 1, 2 and figures 7 to 10). the graphs apply to each driver, regardless of how many other drivers within the package are supplying load current. table 1. mc75172b truth table enables outputs data input en en y z h h x h l h l h h x x h l l h l h h x x l l h h l h l x x l l h l l h l x x l l h l z h z table 2. mc75174b truth table outputs data input enable y z h h h l h l h h h l l h l x h l l z h z h = logic high, l = logic low, x = irrelevant, z = high impedance the two outputs of a driver are always complementary. a ahigho output can only source current out, while a alowo output can only sink current (except for short circuit current see figure 16). the outputs will be in the high impedance mode when: the enable inputs are set according to table 1 or 2; a) v cc is less than 1.5 v; the junction temperature exceeds the trip point of the thermal shutdown circuit (see below). when in this condition, the output's source and sink capability are shut off, and only leakage currents will flow (see figures 13, 14). disabled outputs may be taken to any voltage between 7.0 v and 12 v without damage. b) c) the drivers are protected from short circuits by two methods: current limiting is provided at each output, in both the source and sink direction, for shorts to any voltage within the range of 12v to 7.0v, with respect to circuit ground (see figure 16). the short circuit current will flow until the fault is removed, or until the thermal shutdown circuit activates (see below). the current limiting circuit has a negative temperature coefficient and requires no resetting upon removal of the fault condition. a) a thermal shutdown circuit disables the outputs when the junction temperature reaches 150 c, 20 c. the thermal shutdown circuit has a hysteresis of 12 c to prevent oscillations. when this circuit activates, the output stage of each driver is put into the high impedance mode, thereby shutting off the output currents. the remainder of the internal circuitry remains biased. the outputs will become active once again as the ic cools down. b) driver inputs the driver inputs determine the state of the outputs in accordance with tables 1 and 2. the driver inputs have a nominal threshold of 1.2 v, and their voltage must be kept within the range of 0 v to v cc for proper operation. if the voltage is taken more than 0.5 v below ground, excessive currents will flow, and proper operation of the drivers will be affected. an open pin is equivalent to a logic high, but good design practices dictate that inputs should never be left open. the characteristics of the driver inputs are shown in figure 15. this graph is not affected by the state of the enable pins. enable logic each driver's outputs are active when the enable inputs (pins 4 and 12) are true according to tables 1 and 2. the enable inputs have a nominal threshold of 1.2 v and their voltage must be kept within the range of 0 v to v cc for proper operation. if the voltage is taken more than 0.5 v below ground, excessive currents will flow, and proper operation of the drivers will be affected. an open pin is equivalent to a logic high, but good design practices dictate that inputs should never be left open. the enable input characteristics are shown in figure 15. operating temperature range the minimum ambient operating temperature is listed as 40 c to meet eia485 specifications, and 0 c to meet eia422a specifications. the higher v od required by eia422a is the reason for the narrower temperature range.
mc75172b mc75174b http://onsemi.com 9 the maximum ambient operating temperature (applicable to both eia485 and eia422a) is listed as 85 c. however, a lower ambient may be required depending on system use (i.e. specifically how many drivers within a package are used) and at what current levels they are operating. the maximum power which may be dissipated within the package is determined by: pd max t jmax t a r ja r q ja = package thermal resistance (typical 70 c/w for the dip package, 85 c/w for soic package); t jmax = max. operating junction temperature, and t a = ambient temperature. where: since the thermal shutdown feature has a trip point of 150 c, 20 c, t jmax is selected to be 130 c. the power dissipated within the package is calculated from: = {[(v cc v oh ) ? i oh ] + v ol ? i ol )} each driver = + (v cc ? i cc ) v cc = the supply voltage; v oh , v ol are measured or estimated from figures 7 to 10; i cc = the quiescent power supply current (typical 60 ma). pd where: as indicated in the equation, the first term (in brackets) must be calculated and summed for each of the four drivers, while the last term is common to the entire package. example 1: t a = 25 c, i ol = i oh = 55 ma for each driver, v cc = 5.0 v, dip package. how many drivers per package can be used? maximum allowable power dissipation is: pd max 130 c 25 c 70 c w 1.5 w since the power supply current of 60 ma dissipates 300 mw, that leaves 1.2 w (1.5 w 0.3 w) for the drivers. from figures 7 and 9, v ol 1.75 v, and v oh 3.85 v. the power dissipated in each driver is: {(5.0 3.85) ? 0.055} + (1.75 ? 0.055) = 160 mw. since each driver dissipates 160 mw, the four drivers per package could be used in this application. example 2: t a = 85 c, i ol = 27.8 ma, i oh = 20 ma for each driver, v cc = 5.0 v, soic package. how many drivers per package can be used? maximum allowable power dissipation is: pd max 130 c 85 c 85 c w 0.53 w since the power supply current of 60 ma dissipates 300 mw, that leaves 230 mw (530 mw 300 mw) for the drivers. from figures 8 and 10 (adjusted for v cc = 5.0 v), v ol 1.38 v, and v oh 4.27 v. the power dissipated in each driver is: {(5.0 4.27) ? 0.020} + (1.38 ? 0.0278) = 53 mw since each driver dissipates 53 mw, the use of all four drivers in a package would be marginal. options include reducing the load current, reducing the ambient temperature, and/or providing a heat sink. system requirements eia485 requires each driver to be capable of transmitting data dif ferentially to at least 32 unit loads, plus an equivalent dc termination resistance of 60 w , over a common mode voltage of 7.0 to 12 v. a unit load (u.l.), as defined by eia485, is shown in figure 17. figure 17. unit load definition 1.0 ma v 5.0 v -3.0 v -7.0 v 12 v -0.8 ma reprinted from eia485, electronic industries association, washington,dc. i a load current within the shaded regions represents an impedance of less than one u.l., while a load current of a magnitude outside the shaded area is greater than one u.l. a system's total load is the sum of the unit load equivalents of each receiver's input current, and each disabled driver's output leakage current. the 60 w termination resistance mentioned above allows for two 120 w terminating resistors. using the eia485 requirements (worst case limits), and the graphs of figures 7 and 9, it can be determined that the maximum current an mc75172b or mc75174b driver will source or sink is 65 ma. system example an example of a typical eia485 system is shown in figure 18. in this example, it is assumed each receiver's input characteristics correspond to 1.0 u.l. as defined in figure 17. each aoffo driver, with a maximum leakage of 50 m a over the common mode range, presents a load of 0.06 u.l. the total load for the active driver is therefore 8.3 unit loads, plus the parallel combination of the two terminating resistors (60 w ). it is up to the system software to control the driver enable pins to ensure that only one driver is active at any time.
mc75172b mc75174b http://onsemi.com 10 termination resistors transmission line theory states that, in order to preserve the shape and integrity of a waveform traveling along a cable, the cable must be terminated in an impedance equal to its characteristic impedance. in a system such as that depicted in figure 18, in which data can travel in both directions, both physical ends of the cable must be terminated. stubs, leading to each receiver and driver, should be as short as possible. leaving off the terminations will generally result in reflections which can have amplitudes of several volts above v cc or below ground. these overshoots and undershoots can disrupt the driver and/or receiver operation, create false data, and in some cases damage components on the bus. figure 18. typical eia485 system notes: 1. terminating resistors r t must be located at the physical ends of the cable. 2. stubs should be as short as possible. 3. circuit ground of all drivers and receivers must be connected via a dedicated wire within the cable. do not rely on chassis ground or power line ground. #8 ttl r ttl ttl #3 ttl r en #2 ttl ttl en ttl r ttl #1 r ttl r t #1 en d #3 d #5 d ttl en #6 r ttl r en #5 r #6 d #7 r t ttl ttl r en ttl #4 d 5 aoffo drivers (@ 0.06 u.l. each), +8 receivers (@ 1.0 u.l. each) = 8.3 unit loads r t = 120 w at each end of the cable. #4 d #2 120 w twisted pair
