DESCRIPTION
The 66124 optocoupler consists of two infrared LEDs optically coupled to two corresponding high gain darlington
detectors. This unique quad optocoupler provides high CTR and low leakage currents over the full military temperature
range (-55 to +125C). The 66124 is a 20pin leadless chip carrier hermetically sealed package and is available in
standard and screened versions or tested to customer specifications. MIL-PRF-38534.

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. I
F
= 2
A for channel under test. For all other channels, I
F
= 10mA.
4.
Measured with input pins shorted together and output pins 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
>
@.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).
