DESCRIPTION
The 66123 dual channel optocoupler consists of two LEDs optically coupled to two high speed, high gain inverting detector
gates. Maximum isolation can be achieved while providing TTL outputs capable of switching with propagation delays of 55ns
typical. The 66123 is a 20 pin leadless chip carrier hermetically sealed package and is available in standard and screened
versions or tested to customer specifications.
MIL-PRF-38534
Qualified.

NOTES:
1. Each Channel
2.
Measured between PINS 1 through 8 shorted together and PINS 9 through 16 shorted together.
3.
Measured between PINS 9 and 10 or 11 and 12 shorted together, and PINS 9 through 16 shorted together.
4.
Measured between PINS 9 and 10 shorted together, and PINS 11 and 12 shorted together.
5. The
t
PLH
propagation delay is measured from the 6.5mA point on the trailing edge of the input pulse to the 1.5V point on the trailing edge of the output
pulse.
6. The
t
PHL
propagation delay is measured from the 6.5mA point on the leading edge of the input pulse to the 1.5V point on the leading edge of the output
pulse.
7. CM
H
is the max. tolerable common mode transient to assure that the output will remain in a high logic state (i.e. V
O
>
2.0V).
8. CM
L
is the max. tolerable common mode transient to assure that the output will remain in a low logic state (i.e. V
O
<
0.8v).
9.
It is essential that a bypass capacitor (.01 TO 0.1
F Ceramic) be connected from PIN1 to PIN4.
