Notes:

1. Derate linearly above 85

°C free-air temperature at a rate of 0.5 mA/°C.

2. Derate linearly above 85

°C free-air temperature at a rate of 1.0 mA/°C.

3. Derate linearly above 85

°C free-air temperature at a rate of 1.1 mW/°C.

4. Derate linearly above 85

°C free-air temperature at a rate of 2.3 mW/°C.

5. CURRENT TRANSFER RATIO in percent is defined as the ratio of output collector current, IO, to the forward LED input

current, IF, times 100.

6. Device considered a two terminal device: pins 1 and 3 shorted together, and pins 4, 5 and 6 shorted together.

7. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage

≥ 4500 V

RMS for 1 second

(leakage detection current limit, II-O ≤ 5 µA).

8. Common transient immunity in a Logic High level is the maximum tolerable (positive) dVCM/dt on the rising edge of the

common mode pulse, VCM, to assure that the output will remain in a Logic High state (i.e., VO > 2.0 V). Common mode

transient immunity in a Logic Low level is the maximum tolerable (negative) dVCM/dt on the falling edge of the common mode

pulse signal, VCM to assure that the output will remain in a Logic Low state (i.e., VO < 0.8 V).

9. The 1.9 k

Ω load represents 1 TTL unit load of 1.6 mA and the 5.6 kΩ pull-up resistor.

10. The frequency at which the ac output voltage is 3 dB below its mid-frequency value.

11. Use of a 0.1

µF bypass capacitor connected between pins 4 and 6 is recommended.
