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. Pin 7 open. Use of a resistor between pins 5 and 7 will decrease gain and delay time.
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.
5. 2500 VAC RMS for 1 minute duration is equivalent to 3000 VAC RMS for 1 second duration.
