Description
These units are single, dual and
quad 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.

Critical Systems
Each channel contains an AlGaAs
light emitting diode which is

optically coupled to an integrated
high gain photon detector. The
detector has a threshold with
hysteresis which provides differ-
ential mode noise immunity and
