DESCRIPTION
The 66173 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 65ns
typical. The 66173 is a 10 pin gull wing hermetically sealed package and is available in standard and screened versions or
tested to customer specifications.

Measured between pins 1 through 5 shorted together and pins 6 through 10 shorted together.
3.
Measured between pins 1 and 2 or 4 and 5 shorted together, and pins 6 through 10 shorted together.
4.
Measured between pins 1 and 2 shorted together, and pins 4 and 5 shorted together.
5. The
t

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

<
0.8V).
9.
It is essential that a bypass capacitor (.01 to 0.1
F ceramic) be connected from pin 6 to pin 10.
