Description

These HCPL-177K units are single, dual, and quad channel, hermetically sealed optocouplers. The HCPL-177K 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 DSCC Drawing. All devices are manufactured and tested on a MIL-PRF-38534 certified line and are included in the DSCC Qualified Manufacturers List QML- 38534 for Hybrid Microcircuits.

Each HCPL-177K channel contains a GaAsP light emitting diode which is optically coupled to an integrated high gain photon detector. The high gain output stage features an open collector output providing both lower saturation voltage and
higher signaling speed than possible with conventional photo-Darlington optocouplers. The shallow depth and small junctions offered by the IC process provides better radiation immunity than conventional photo transistor optocouplers.

The supply voltage of HCPL-177K can be operated as low as 2.0 V without adversely affecting the parametric performance.
