Notes

1. Current Transfer Ratio is deﬁned as a ratio of output collector current, I , to the forward LED input current, I , times 100%.

F

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 /dt on the leading edge of the

cm

common mode pulse signal V , to assure that the output will remain in a logic high state (i.e., V >2.0 V). Common mode

CM

O

transient immunity in logic low level is the maximum tolerable (negative) dV /dt on the trailing edge of the common mode

cm

pulse signal, V , to assure that the output will remain in a logic low state (i.e., V <0.8 V).

CM

O

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