Hermetically Sealed Low IF, Wide VCC, Logic Gate Optocouplers
Data Sheet
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 certified
line and are included in the DSCC Qualified 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 differential 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.

Package styles for these parts are 8 pin DIP through hole
(case outline P), 16 pin DIP flat pack (case outline F), and
leadless ceramic chip carrier (case outline 2). Devices
may be purchased with a variety of lead bend and plat-
ing options, see Selection Guide Table for details. Stan-
dard Microcircuit Drawing (SMD) parts are available for
each package and lead style.
Because the same electrical die (emitters and detectors)
are used for each channel of each device listed in this
data sheet, absolute maximum ratings, recommend-
ed operating conditions, electrical specifications, and
performance characteristics shown in the figures are
identical for all parts. Occasional exceptions exist due
to package variations and limitations and are as noted.
Additionally, the same package assembly processes and
materials are used in all devices. These similarities give
justification for the use of data obtained from one part
to represent other part’s performance for die related reli-
ability and certain limited radiation test results.
