Description

These units are single and dual

channel, hermetically sealed

optocouplers. The products are

capable of operation and storage

over the full military temperature

range and can be purchased as

either standard product or with

full MIL-PRF-38534 Class Level

H or K testing or from the

appropriate DESC Drawing. All

devices are manufactured and

tested on a MIL-PRF-38534

certified line and are included in

the DESC Qualified Manufac-

turers List QML-38534 for Hybrid

Microcircuits.

CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to

prevent damage and/or degradation which may be induced by ESD.
