DESCRIPTION
These dual channel diode-darlington optocouplers
use a pair of light emitting diodes and an integrated
high gain photon detectors to provide 2500Volts
RMS
electrical isolation between input and output.
Seperate connection for the photodiode bias and
output darlington collector improve the speed up to
a hundred times that of a conventional photo-
darlington coupler by reducing the base-collector
capacitance.

5.
Each channel.
6.
CURRENT TRANSFER RATIO is defined as the ratio of output collector current,I
O
, to the forward LED
input current, I
F
times 100%.
7.
Measured between pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
8.
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
CM
to assure that the output will remain in Logic
Low state (i.e. V
O
< 0.8V).Measured in volts per microsecond (V/
s).
9.
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
CM
to assure that the output will remain in a Logic High
state (i.e. V
O
> 2.0V).Measured in volts per microsecond (V/
s).
10.
Device considered a two-terminal device: pins 1,2,3, and 4 shorted together and pins 5,6,7 and 8 shorted
together.
