Description
The ACPL-K453 is a single channel devices in an eight lead
miniature footprint.
This diode-transistor optocoupler uses an insulating layer
between the light emitting diode and an integrated pho-
to detector to provide electrical insulation between input
and output. Separate connections for the photodiode bias
and output transistor collector increase the speed up to a
hundred times over that of a conventional photo-transis-
tor coupler by reducing the base-collector capacitance.
The ACPL-K453 has a common mode transient immunity
of 15,000 V/Ps minimum at V
CM
= 1500 V guaranteed.

Applications
x Line Receivers - High common mode transient immu-
nity (>15000 V/Ps) and low input-output capacitance
(0.6 pF).
x High Speed Logic Ground Isolation - TTL/TTL, TTL/LTTL,
TTL/CMOS, TTL/LSTTL.
x Replace Slow Phototransistor Optocouplers
x Replace Pulse Transformers - Save board space and
weight
x Analog Signal Ground Isolation - Integrated photo de-
tector provides improved linearity over phototransistor
type.
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.
