Notes
1. Current Transfer Ratio is defined as a ratio of output collector current, I_O, to the forward LED input current, I_F, times 100%.
2. The 1.9 kΩ load represents 1 TTL unit load of 1.6 mA and 5.6 kΩ pull-up resistor.
3. Common mode transient immunity in logic high level is the maximum tolerable (positive) dV_cm/dt on the leading edge of the
common mode pulse signal V_CM, to assure that the output will remain in a logic high state (i.e., V_O>2.0 V). Common mode
transient immunity in logic low level is the maximum tolerable (negative) dV_cm/dt on the trailing edge of the common mode
pulse signal, V_CM, to assure that the output will remain in a logic low state (i.e., V_O<0.8 V).
4. Device is considered a two terminal device: Pins 1, 2, 3 and 4 are shorted together and Pins 5, 6, 7 and 8 are shorted
together.
