1. Current Transfer Ratio is defined as a ratio of output collector current, I
2. Pin 7 open. (FOD070L and FOD270L only)
3. Common mode transient immunity in logic high level is the maximum tolerable (positive) dV
common mode pulse signal, V
CM
, to assure that the output will remain in a logic high state (i.e., V
transient immunity in logic low level is the maximum tolerable (negative) dV
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.
5. For dual channel devices, CI-O is measured by shorting pins 1 and 2 or pins 3 and 4 together and pins 5 through 8 shorted
together.
6. Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
