Description
These units are single, dual and quad channel, hermeti-
cally sealed optocouplers. The products are capable of
operation and storage over the full military temperature
range and can be purchased as either standard prod-
uct 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 certi ed
line and are included in the DSCC Quali ed Manufactur-
ers List QML-38534 for Hybrid Microcircuits.
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 hys-
teresis which provides di erential mode noise immunity
and eliminates the potential for output signal chatter.
The detector in the single channel units has a tri-state
output stage which allows for direct connection to data
buses. The output is noninverting. The detector IC has
an internal shield that provides a guaranteed common
mode transient immunity of up to 10,000 V/μs. Improved
power supply rejection eliminates the need for special
power supply bypass precautions.
Note: A 0.1 F bypass capacitor must be connected between VCC and GND pins.
