Description
These dual channel optocoup lers contain a pair of light
emitting diodes and integrated photo-detec tors with
electrical insulation between input and output. Separate
connection for the photodiode bias and output transis-
tor collectors increase the speed up to a hundred times
that of a conventional phototransistor coupler by
reducing the base-collector capacitance.
These dual channel optocouplers are available in an 8
Pin DIP and in an industry standard SO-8 package. The
following is a cross reference table listing the 8 Pin DIP
part number and the electrically equivalent SO-8 part
number.

• Single channel version available (4502/3, 0452/3)
• MIL-PRF-38534 hermetic version available
(55XX/65XX/4N55)
Applications
• Line receivers – high common mode transient immu-
nity (>1000 V/µs) and low input-output capacitance
(0.6 pF)
• High speed logic ground isolation – TTL/TTL, TTL/LTTL,
TTL/CMOS, TTL/LSTTL
• Replace pulse transformers – save board space and
weight
• Analog signal ground isolation – integrated photon
detector provides improved linearity over phototran-
sistor type
• Polarity sensing
• Isolated analog amplier – dual channel packaging
enhances thermal tracking
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.
A 0.1 µF bypass capacitor between
pins 5 and 8 is recommended.
