* The Input-Output Momentary Withstand Voltage is a dielectric voltage rating that should not be interpreted as an input-output continuous
voltage rating.
Notes:
1. Current Transfer Ratio in percent is de ned as the ratio of output collector current, I
O
, to the forward LED input current, I
F
, times 100.
2. Device considered a two terminal device: pins 1, 2, 3 and 4 shorted together, and pins 5, 6, 7 and 8 shorted together.
3. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000 V
RMS
for 1 second.
4. Common transient immunity in a Logic High level is the maximum tolerable (positive) dV
CM
/dt on the rising edge of the common mode pulse, V
CM
,
to assure that the output will remain in a Logic High state (i.e., Vo > 2.0 V). Common mode transient immunity in a Logic Low level is the maximum
tolerable (negative) dV
CM
/dt on the falling edge of the common mode pulse signal, V
CM
to assure that the output will remain in a Logic Low state
(i.e., Vo < 0.8 V).
