Notes:
1. Each channel.
2. CURRENT TRANSFER RATIO is defined as the ratio of output collector current, IO, to the forward LED input current, IF, times 100%.
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. Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
5. Common mode 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).
6. The 1.9 k: load represents 1 TTL unit load of 1.6 mA and the 5.6 kΩ pull-up resistor.
7. The 4.1 k: load represents 1 LSTTL unit load of 0.36 mA and the 6.1 kΩ pull-up resistor.
8. The frequency at which the ac output voltage is 3 dB below the low frequency asymptote.
9. Use of a 0.1 PF bypass capacitor connected between pins 5 and 8 is recommended.
10. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage ≥4500 V rms for 1 second (leakage detec-
tion current limit, II-O ≤5 PA).
11. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage ≥6000 V rms for 1 second (leakage detec-
tion current limit, II-O ≤5 PA).
12. Measured between the LED anode and cathode shorted together and pins 5 through 8 shorted together.
13. Derate linearly above 90°C free-air temperature at a rate of 3.0 mW/ °C for the SOIC-8 package.
