Description
These units are single, dual and
quad 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 DESC Drawing. All
devices are manufactured and
tested on a MIL-PRF-38534
certified line and are included in
the DESC Qualified
Manufacturers List QML-38534
for Hybrid Microcircuits.
Each channel contains a GaAsP
light emitting diode which is
optically coupled to an integrated
photon detector. Separate
connections for the photodiodes
and output transistor collectors
improve the speed up to a
hundred times that of a conven-
tional phototransistor
optocoupler by reducing the
base-collector capacitance.
These devices are suitable for
wide bandwidth analog applica-
tions, as well as for interfacing
TTL to LSTTL or CMOS. Current
Transfer Ratio (CTR) is 9% mini-
mum at IF = 16 mA. The 18 V VCC
