DESCRIPTION
.
The 66197 optocoupler contains two completely isolated optocouplers in a hermetically sealed dual inline package and is
electrically similar to the 4N55. This product has been designed to be more tolerant to Proton Radiation. Each channel
provides high switching speeds while providing high isolation (1500V min). The 66197 is available in standard and MILPRF-38534 screened versions or tested to customer specifications.

NOTES:
1.
Each channel.
2.
CURRENT TRANSFER RATIO is defined as the ratio of output collector current, IO, to the forward LED input current, IF , 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.
CMH is the maximum tolerable common mode transient to assure that the output will remain in a high logic state (ie. VO > 2.0V).
6.
CML is the maximum tolerable common mode transient to assure that the output will remain in a low logic state (ie. VO < 0.8V).
