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 DLA Drawing. All devices are man-
ufactured and tested on a MIL-PRF-38534 certified line
and are included in the DLA Qualified Manufacturers List,
QML-38534 for Hybrid Microcircuits.
