Description
These dual channel devices are optically coupled logic gates that combine GaAsP light emitting diodes and integrated high gain photodetectors. The photons are collected in the detector by a photodiode and the current is amplified by a high gain linear amplifier that drives a Schottky clamped open collector output transistor. Each circuit is temperature, current and voltage compensated. The internal shield provides a guaranteed common mode transient immunity specification of 5000 V/s for the HCPL2631/0631, and 10,000 V/ s for the HCPL-4661/0661. These dual channel optocouplers are available in an 8 Pin DIP and in an industry standard SOIC-8 package. The following is a cross reference table listing the 8 Pin DIP part number and the electrically equivalent SOIC-8 part number. SOIC-8 Package HCPL-0630 HCPL-0631 HCPL-0661
+85C. The dual channel design minimizes PCB space. These devices are recommended for high speed logic interfacing, input/output buffering, and for use as line receivers in environments that conventional line receivers cannot tolerate. They can be used for the digital programming of machine control systems, motors and floating power supplies. The internal shield makes the HCPL-2631/0631/4661/0661 ideal for use in extremely high ground or induced noise environments.

*All typical values are at VCC = 5 V, TA = 25C. Notes: 1. Bypassing of the power supply line is required with a 0.1 F ceramic disc capacitor adjacent to each optocoupler. Total lead length between both ends of the capacitor and the isolator pins should not exceed 10 mm. 2. Peaking circuits may produce transient input currents up to 50 mA, 50 ns maximum pulse width, provided average current does not exceed 15 mA. 3. Each channel. 4. Measured between pins 1, 2, 3, and 4 shorted together, and pins 5, 6, 7, and 8 shorted together. 5. Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together. 6. The tPLH propagation delay is measured from the 3.75 mA point on the falling edge of the input pulse to the 1.5 V point on the rising edge of the output pulse. 7. The tPHL propagation delay is measured from the 3.75 mA point on the rising edge of the input pulse to the 1.5 V point on the falling edge of the output pulse. 8. CMH 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., VOUT > 2.0 V). 9. CML 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., VOUT < 0.8 V). 10. For sinusoidal voltages, (|dVCM|/dt)max = fCMVCM(p-p). 11. As illustrated in Figure 15 the VCC and GND traces can be located between the input and the output leads to provide additional noise immunity at the compromise of insulation capability. 12. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage 3000 VRMS for 1 second (Leakage detection current limit, II-O 5 A). 13. See application section; "Propagation Delay, Pulse-Width Distortion and Propagation Delay Skew" for more information. 14. tPSK is equal to the worst case difference in tPHL and/or tPLH that will be seen between units at any given temperature within the operating condition range. 15. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage 6000 VRMS for 1 second (Leakage detection current limit, II-O 5 A). This option is valid for HCPL-2630/2631/4661 only. 16. Measured between the LED anode and cathode shorted together and pins 5 through 8 shorted together. 17. Derate linearly above 80C free-air temperature at a rate of 2.7 mW/C for the SOIC-8 package.

Propagation Delay, Pulse-Width Distortion and Propagation Delay Skew
Propagation delay is a figure of merit which describes how quickly a logic signal propagates through a system. The propagation 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 7).
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-1, etc.). Propagation delay skew, tPSK, is an important parameter to consider in parallel data appli-
cations 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
H
group of optocouplers which are operating under the same conditions (i.e., the same drive current, supply voltage, output load, and operating temperature). As illustrated in Figure 17, 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 tPHL or tPHL, and the longest propagation delay, either tPLH or tPHL. As mentioned earlier, tPSK can determine the maximum parallel data transmission rate. Figure 18 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 represents the uncertainty of where an edge might be after being sent through an optocoupler. Figure 18 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 offers the advantages of guaranteed specifications for propagation delays, pulse-width distortion and propagation delay skew over the recommended temperature, input current, and power supply ranges.
