They offer the designer a broad range of input drive current, from 7 mA to 15 mA, thus providing greater flexibility in designing the drive circuit. The output detector integrated circuit (IC) in the optocoupler consists of a photodiode at the input of a twostage amplifier that provides both high gain and high bandwidth. The secondary amplifier stage of the detector The entire output circuit is electrically shielded so that any common-mode transient capacitively coupled from the LED side of the optocoupler is diverted from the photodiode to ground. With this electric shield, the optocoupler can withstand transients that slopes up to 10,000V/s, and amplitudes up to 1,000V.

In order to guarantee that the optocoupler is OFF, the forward voltage across the LED must be less than or equal to 0.8 volt for the entire operating temperature range. This has direct implications for the input drive circuit. If the design uses a TTL gate to drive the input LED, then one has to ensure that the gate output voltage is sufficient to cause the forward voltage to be less than 0.8 volt. The typical threshold current for the ACSL-6xx0 series optocouplers is 2.7 mA; however, this threshold could increase over time due to the aging effects of the LED. Drive circuit arrangements must provide for the ON state LED forward current of at least 7 mA, or more if faster operation is desired. Maximum Input Current and Reverse Voltage The average forward input current should not exceed the 15 mA Absolute Maximum Rating as stated; however, peaking circuits with transient input currents up to 50 mA are allowed provided the average current does not exceed 15 mA. If the input current maximum rating is exceeded, Figure 18. TTL interface circuit for the ACSL-6xx0. 16 the local temperature of the LED can rise, which in turn may affect the long-term reliability of the device. When designing the input circuit, one must also ensure that the input reverse voltage does not exceed 5 V. If the optocoupler is subjected to reverse voltage transients or accidental situations that may cause a reverse voltage to be applied, thus an antiparallel diode across the LED is recommended. Suggested Input Circuits for Driving the LED Figures 18, 19, and 20 show some of the several techniques for driving the ACSL-6xx0 LED. Figure 18 shows the recommended circuit when using any type of TTL gate. The buffer PNP transistor allows the circuit to be used with TTL or CMOS gates that have low sinking current capability. One advantage of this circuit is that there is very little variation in power supply current due to the switching of the optocoupler LED. This can be important in high-resolution analog-to-digital (A/D) systems where ground loop currents due to the switching of the LEDs can cause distortion in the A/D output. With a CMOS gate to drive the optocoupler, the circuit shown in Figure 19 can be used. The diode in parallel to the current limiting resistor speeds the turn-off of the optocoupler LED. Any HC or HCT series CMOS gate can be used in this circuit. For high common-mode rejection applications, the drive circuit shown in Figure 20 is recommended. In this circuit, only an open-collector TTL, or an open drain CMOS gate can be used. This circuit drives the optocoupler LED with a 220 ohm current-limiting resistor to ensure that an IF of 7 mA is applied under worst case conditions and thus guarantee the 10,000 V/s optocoupler common mode rejection rating. The designer can obtain even higher common-mode rejection performance than 10,000 V/s by driving the LED harder than 7 mA. Phase Relationship to Input The output of the optocoupler is inverted when compared to the input. The input is defined to be logic HIGH when the LED is ON. If there is a design that requires the optocoupler to behave as a non-inverting gate, then the series input drive circuit shown in Figure 19 can be used. This input drive circuit has an inverting function, and since the optocoupler also behaves as an inverter, the total circuit is non-inverting. The shunt drive circuits shown in Figures 18 and 20 will cause the optocoupler to function as an inverter. Current and Voltage Limitations The absolute maximum voltage allowable at the output supply voltage pin and the output voltage pin of the optocoupler is 7 volts. However, the recommended maximum voltage at these two pins is 5.5 volts. The output sinking current should not exceed 13 mA in order to make the Low Level Output Voltage be less than 0.6 volt. If the output voltage is not a consideration, then the absolute maximum current allowed through the ACSL-6xx0 is 50 mA. If the output requires switching either higher currents or voltages, output buffer stages as shown in Figures 21 and 22 are suggested. Figure 19. CMOS drive circuit for the ACSL-6xx0. Figure 21.

The propaga- tion delay from low to high (tPLH) is the amount of time required for an input signal to propagate to the output,causing the output to change from low to high. Similarly,the propagation delay from high to low (tPHL) is the amount of time required for the input signal to propagate to the output causing the output to change from high to low (see Figure 16). Pulse-width distortion (PWD) results when tPLH and tPHL differ in value. PWD is defined as the difference between tPLH and tPHL and often determines the maximum data rate capability of a transmission system. PWD can be expressed in percent by dividing the PWD (in ns) by the minimum pulse width (in ns) being transmitted. Typically, PWD on the order of 20-30% of the minimum pulse width is tolerable; the exact figure depends on the particular application (RS232, RS422, T-l, etc.). Propagation delay skew,tPSK, is an important parameter to consider in parallel data applica- tions where synchronization of signals on parallel data lines is a concern. If the parallel data is being sent through a group of optocouplers, differences in propagation delays will cause the data to arrive at the outputs of the optocouplers at different times. If this difference in propagation delays is large enough, it will determine the maximum rate at which parallel data can be sent through the optocouplers. Propagation delay skew is defined as the difference between the minimum and maximum propagation delays,either tPLH or tPHL, for any given group of optocouplers which are operating under the same conditions (i.e., Figure 23. Propagation delay skew - tPSK. 18 the same drive current, supply voltage, output load, and operating temperature). As illustrated in Figure 23, if the inputs of a group of optocouplers are switched either ON or OFF at the same time, tPSK is the difference between the shortest propagation delay,either tPLH or tPHL, and the longest propagation delay,either tPLH or tPHL. As mentioned earlier,tPSK can determine the maximum parallel data transmission rate. Figure 24 is the timing diagram of a typical parallel data application with both the clock and the data lines being sent through optocouplers. The figure shows data and clock signals at the inputs and outputs of the optocouplers. To obtain the maximum data transmission rate, both edges of the clock signal are being used to clock the data;if only one edge were used, the clock signal would need to be twice as fast. Propagation delay skew repre- sents the uncertainty of where an edge might be after being sent through an optocoupler. Figure 24 shows that there will be uncertainty in both the data and the clock lines. It is important that these two areas of uncertainty not overlap, otherwise the clock signal might arrive before all of the data outputs have settled,or some of the data outputs may start to change before the clock signal has arrived. From these considerations, the absolute minimum pulse width that can be sent through optocouplers in a parallel application is twice tPSK. A cautious design should use a slightly longer pulse width to ensure that any additional uncertainty in the rest of the circuit does not cause a problem. The tPSK specified optocouplers offer the advantages of guaranteed specifications for propagation delays, pulsewidth distortion and propagation delay skew over the recommended temperature, input current, and power supply ranges.
