DESCRIPTION
The 66088 single/dual optocouplers utilize infrared LEDs optically coupled to high gain photon detectors. These unique
optocouplers provide high CTR and low leakage current. The 66088 optocouplers are available in military temperature range
and military temperature with 100% device screening. The devices are built in an 8 pin hermetic, side-brazed package and
provide high input to output isolation (1500Vdc minimum).

CC
as low as possible, but greater than 2V. The negative
voltage at the detector side should be applied to PIN 5.

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
>
2.0V).
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).
