HCPL-576x*
5962-8947701
AC/DC to Logic Interface Hermetically Sealed Optocouplers
Data Sheet
Description
These devices are single channel, hermetically sealed,
voltage/current threshold detection 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 DLA Standard Micro-cir-
cuit Drawing (SMD) 5962-89477. All devices are manu-
factured and tested on a MIL-PRF-38534 certified line
and are included in the DLA Qualified Manufacturers List,
QML-38534 for Hybrid Microcircuits.
