high-performance products ?ate 1 www.semtech.com edge818 octal 18v pin electronics driver/window comparator description features functional block diagram applications revision 3 / december 3, 2001 the edge818 is an octal pin electronics driver and window comparator fabricated in a wide voltage cmos process. it is designed specifically for test during burn in (tdbi) applications, where cost, functional density, and power are all at a premium. the edge818 incorporates eight channels of programmable drivers and window comparators into one 14 mm x 20 mm 100 pin mqfp package. each channel has per pin driver levels, data, and high impedance control. in addition, each comparator has per pin high and low threshold levels. the edge818 uses "flex in" and "flex out" digital inputs, and can therefore mate directly with any digital technology providing a minimum 2v swing. the digital outputs can mate directly with any digital technology. the 18v driver output and receiver input range allow the edge818 to interface directly with ttl, ecl, cmos (3v, 5v, and 7v), lvcmos, and custom level circuitry, as well as the high voltage (super voltage) level required for many special test modes for flash devices. ? 18v i/o range ? 50 mhz operation ? per pin flexibility ? programmable input thresholds ? flex in digital inputs ? flex out digital outputs ? small footprint (100 pin mqfp) ? burn in ate ? low cost ate ? instrumentation 8 8 8 8 8 8 8 8 data en* qa comp high comp low qb vh vl dout cva vinp cvb C + + C

4 ? 2000 semtech corp. www.semtech.com high-performance products ?ate edge818 circuit description driver description the edge818 supports programmable high and low levels and tristate per channel. there are no shared lines between any drivers. the en* and data signals are wide voltage high impedance analog inputs capable of receiving digital signals over a wide common mode range. vbb is the high impedance analog input which sets the threshold for en* and data. en*, da t a status > vbb "1" < vbb "0" with en* high, the driver goes into a high impedance state. with en* low, data high forces the driver into a high state, and data low forces the driver into a low state. en* da t a dout 1x hiz 01 vh 00 vl drive high and low vh and vl define the logical "1" and "0" levels of the driver, and can be adjusted anywhere over the range determined by vcc and vee. there are no restrictions between vh and vl, other than they must remain within the power supply levels. vee vh vcc vee vl vcc the vh and vl inputs are unbuffered in that they also provide the driver output current (see figure 3), so the source of vh and vl must have ample current drive capability. figure 3. simplified model of the unbuffered output stage driver output protection in a functional testing environment, where a resistor is added in series with the driver output to create a 50 ? driver, the edge818 can withstand a short to any legal voltage for an indefinite amount of time. in a low impedance application, with no additional output resistance, the system should be designed to check for a short circuit prior to connecting the driver, and tristate the driver if a short is detected. receiver description the edge818 supports a window comparator with independent threshold levels per channel. there are no shared comparator lines between channels. cva and cvb are high impedance analog voltage inputs which define the threshold voltages for comparators a and b. if vinp is more positive than cva or cvb, qa and qb will be high. otherwise, qa and qb will be low. vinp qa vinp > cva comp high vinp < cva comp low vinp qb vinp > cvb comp high vinp < cvb comp low vh vl dut

6 ? 2000 semtech corp. www.semtech.com high-performance products ?ate edge818 application information power supply decoupling vcc and vee should be decoupled to gnd with a .1 f chip capacitor in parallel with a .001 f chip capacitor. a vcc and vee plane, or at least a solid power bus, is recommended for optimal performance. vh and vl decoupling as the vh and vl inputs are unbuffered and supply the driver output current, which can be quite large during edge transitions, decoupling capacitors for these inputs are recommended in proportion to the amount of output current requirements. for applications where vh and vl are shared over multiple channels, a solid power plane to distribute these levels is preferred. vbb the two vbb pins are connected together on-chip. therefore, only one vbb needs to be connected to for proper 818 operation. the two pins may be used to daisy chain a vbb signal across a pc board without having to route the actual signal underneath the 818. latchup protection the edge818 has several power supply requirements to protect the part in power supply fault situations, as well as during power up and power down sequences. vcc must remain greater than or equal to vdd (external supply for the digital logic) at all times. both vcc and vdd must always be positive (above ground), and vee must always be negative (at or below ground). the three diode configuration shown in figure 5 should be used on a once-per-board basis. figure 5. power supply protection scheme gure 5. warning: it is extremely important that the voltage on any device pin does not exceed the range of vee ?.5v to vcc +0.5v at any time, either during power up, normal operation, or during power down. failure to adhere to this requirement could result in latchup of the device, which could be destructive if the system power supplies are capable of supplying large amounts of current. even if the device is not immediately destroyed, the cumulative damage caused by the stress of repeated latchup may affect device reliability. vcc vdd vee 1n5820 or !"#$%&'
