Data Sheet
CAUTION: It is advised that normal static precautions be taken in handling and assembly
of this component to prevent damage and/or degradation which may be induced by ESD.
Description
These devices are single, dual, and quad channel, hermeti-
cally sealed optocoup lers. 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 DLA Drawing 5962-08227. All devices are manufac-
tured and tested on a MIL-PRF-38534 certi ed line and are
included in the DLA Quali ed Products Database Supple-
mental Information Sheets QPDSIS-38534 as Hybrid Mi-
crocircuits.
Each 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 conven-
tional photo-Darling ton optocouplers.
The supply voltage can be operated as low as 3.0 V without
adversely a ecting the parametric performance.
These devices have a 300% minimum CTR at an input
current of only 0.5 mA making them ideal for use in low
input current applications such as MOS, CMOS, low power
logic interfaces or line receivers.
The connection of a 0.1
F bypass capacitor between V
CC
and GND is recommended.
