DESCRIPTION
The 66181 high voltage isolator consisting of a LED optically coupled to a high speed, high gain inverting detector gate.
Output is TTL capable with switching propagation delays of 55ns typical, hermetically sealed in TO-46 packages and mounted
in a highly reliability, hermetically sealed ceramic package. Available in commercial (0
to +70
C), extended temperature range
(-40
to +85
) and full Military temperature range (-55
to +125
C). Contact the factory for special custom or multi-channel
requirements!

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 pin 1 to pin 4.
