Description
The HCPL-7601/11 is a low input current version of the HCPL-2601/11 and 6N137 (without enable). The optically coupled gates combine an AlGaAs high-efficiency light emitting diode and an integrated high gain photon detector to create a low input current device for low power applications. The output of the detector IC is an open collector Schottky-clamped transistor. The internal shield provides a guaranteed common mode transient immunity specification of 10,000 V/s (HCPL-7611). This unique design provides maximum ac and dc circuit isolation while achieving CMOS and TTL compatibility. The optocoupler ac and dc operational parameters are guaranteed from -40C to 85C with no derating required allowing trouble free system performance. This product is suitable for high speed logic interfacing, input/output buffering, and applications that require low input-current switching levels.
The HCPL-7601/11 family offers many features that are especially beneficial to system designers. The low input current requirements and guaranteed switching threshold (2 mA max.) allows the LED to be driven directly by any standard high-speed CMOS gate (e.g. 74HC/HCT). This will simplify designs by eliminating the need for special driver circuits and result in lower part counts and greater system reliability while freeing up valuable printed circuit board space. The wide current input range of 2 mA to 10 mA and guaranteed ac and dc performance over a wide temperature range will also simplify designs. Low supply current requirements mean lower power dissipation allowing for the use of a smaller, less expensive power supply. The high speed (10 Mbd typ.) and low propagation delay skew (Tpsk 40 ns guaranteed) allow for easier design of high speed parallel applications. The world-wide regulatory approval (UL/CSA/VDE 0884) will facilitate the acceptance of the end product in international markets.

Notes: 1. Bypassing of the power supply line is required with a 0.1 F ceramic disc capacitor adjacent to each optocoupler, as illustrated in Figure 15. 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 20 mA. 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 tPLH 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 tPHL 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. 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. 7. 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., VOUT > 2.0 V).
8. 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). This specification assumes that good board layout procedures were followed to reduce the effective input/output capacitance as shown in Figure 15. 9. In accordance with UL and CSA requirements, each optocoupler is proof tested by applying an insulation test voltage 5000 Vrms for one second (leakage detection current limit, II-O 5 A). 10. AC performance at IF = 4 mA is approximately equivalent to the HCPL-2601/11 at IF = 7.5 mA for comparison purposes.
