7 notes: 1. bypassing the power supply line is required with a 0.1 m f ceramic disc capacitor adjacent to each optocoupler as illustrated in figure 19. the power supply bus for the optocoupler(s) should be separate from the bus for any active loads, otherwise a larger value of bypass capacitor (up to 0.5 m f) may be needed to suppress regenerative feedback via the power supply. 2. peaking circuits may produce transient input currents up to 100 ma, 500 ns maximum pulse width, provided average current does not exceed 5 ma. package characteristics for -40 c t a 85 c, unless otherwise specified. all typicals at t a = 25 c. parameter symbol min. typ. max. units test conditions fig. notes input-output momentary v iso 2500 v rms rh 50%, t = 1 min, 3, 9 withstand voltage* t a = 25 c resistance, input-output r i-o 10 12 w v i-o = 500 v 3 capacitance, input-output c i-o 0.6 pf f = 1 mhz 3 *the input-output momentary withstand voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous voltage rating. for the continuous voltage rating refer to the vde 0884 insulation characteristics table (if applicable), your equipment level safety specification, or agilent application note 1074, optocoupler input-output endurance voltage. 7. cm l is the maximum tolerable rate of fall of the common mode voltage to assure that the output will remain in a low logic state (i.e., v out < 0.8 v). 8. c p is the peaking capacitance. refer to test circuit in figure 8. 9. in accordance with ul 1577, each optocoupler is momentary withstand proof tested by applying an insulation test voltage 3 3000 vrms for 1 second (leakage detection current limit, i i-o 5 m a). this test is performed before the 100% production test for partial discharge (method b) shown in the vde 0884 insulation character- istics table, if applicable. 3. device considered a two terminal device: pins 1, 2, 3, and 4 shorted together, and pins 5, 6, 7, and 8 shorted together. 4. the t plh propagation delay is measured from the 50% point on the trailing edge of the input pulse to the 1.5 v point on the trailing edge of the output pulse. 5. the t phl propagation delay is measured from the 50% point on the leading edge of the input pulse to the 1.5 v point on the leading edge of the output pulse. 6. cm h is the maximum tolerable rate of rise of the common mode voltage to assure that the output will remain in a high logic state (i.e., v out > 2.0 v). figure 3. typical output voltage vs. forward input current vs. temperature. figure 2. typical input diode forward characteristics. figure 4. typical logic high output current vs. temperature.

9 applications the hcpl-2300 optocoupler has the unique combination of low 0.5 ma led operating drive current at a 5 mbd speed performance. low power supply current requirement of 10 ma maximum at 5.25 v and the ability to provide isolation between logic systems fulfills numerous applications ranging from logic level translations, line receiver and party line receiver applications, microprocessor i/o port isolation, etc. the open col- lector output allows for wired-or arrangement. specific interface circuits are illustrated in figures 12-16, and 18 with correspond- ing component values, perform- ance data and recommended layout in figures 17 and 19. for -40 c to 85 c operating temperature range, a mid-range led forward current (i f ) of 0.625 ma is recommended in order to prevent overdriving the integrated circuit detector due to increased led efficiency at temperatures between 0 c and -40 c. for narrower temperature range of 0 c to 85 c, a suggested operating led current of 0.75 ma is recommended for the mid-range operating point and for minimal propagation delay skew. a peaking capacitance of 20 pf in parallel with the current limiting resistor for the led shortens t phl by approximately 33% and t plh by 13%. maintain- ing led forward voltage (v f ) below 0.8 v will guarantee that the hcpl-2300 output is off. the recommended shunt drive technique for ttl/lsttl/cmos of figure 12 provides for optimal speed performance, no leakage current path through the led, and reduced common mode influences associated with series switching of a floating led. alternate series drive techniques with either an active cmos inverter or an open collector ttl/ lsttl inverter are illustrated in figures 13 and 14 respectively. open collector leakage current of 250 m a has been compensated by the 3.16 k w resistor (figure 14) at the expense of twice the operating forward current. an application of the hcpl-2300 as an unbalanced line receiver for use in long line twisted wire pair communication links is shown in figure 15. low led i f and v f allow longer line length, higher speed and multiple stations on the line in comparison to higher i f , v f optocouplers. greater speed performance along with nearly infinite common mode immunity are achieved via the balanced split phase circuit of figure 16. basic balanced differential line receiver can be accomplished with one hcpl- 2300 in figure 16, but with a typical 400 v/ m s common mode immunity. data rate versus distance for both the above unbalanced and balanced line receiver applications are com- pared in figure 17. the rs-232-c interface circuit of figure 18 figure 10. test circuit for common mode transient immunity and typical waveforms. figure 11. thermal derating curve, dependence of safety limiting value with case temperature per vde 0884. output power ?p s , input current ?i s 0 0 t s ?case temperature ?? 200 50 400 125 25 75 100 150 600 800 200 100 300 500 700 p s (mw) i s (ma) 175
