NOTES:
1.
Each channel.
2.
CURRENT TRANSFER RATIO is defined as the ratio of output collector current, I
O
, to the forward LED input current, I
F
, times 100%.
3.
Measured between each input pair shorted together.
4.
Measured between input pins shorted together and the output pins for that channel shorted together.
5.
CM
H
is the maximum tolerable common mode transient to assure that the output will remain in a high logic state (ie. V
O
>
@.0V).
6.
CM
L
is the maximum tolerable common mode transient to assure that the output will remain in a low logic state (ie. V
O
<
0.8V).
