Each channel.
CURRENT TRANSFER RATIO is defined as the ratio of output collector current,I
O
, to the forward LED
input current, I
times 100%.
Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
Common mode transient immunity in Logic Low level is the maximum tolerable (negative) dVcm/dt on
the trailing edge of the common mode pulse signal, V
to assure that the output will remain in Logic
Low state (i.e. V
< 0.8V).Measured in volts per microsecond (V/
μ
s).
Common mode transient immunity in Logic High level is the maximum tolerable (positive) dVcm/dt on
the leading edge of the common mode pulse V
to assure that the output will remain in a Logic High
state (i.e. V
> 2.0V).Measured in volts per microsecond (V/
μ
s).
Device considered a two-terminal device: pins 1,2,3, and 4 shorted together and pins 5,6,7 and 8 shorted
together.
