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.
