Description
These small outline high CMR, high speed, diode-transistor
optocouplers are single channel devices in a five lead
miniature footprint. They are electrically equivalent to the
following Broadcom® optocouplers.
The SO-5 JEDEC registered (MO-155) package outline
does not require "through holes" in a PCB. This package
occupies approximately one-fourth the footprint area of the
standard dual-inline package. The lead profile is designed to
be compatible with standard surface mount processes.
These diode-transistor optocouplers use an insulating layer
between the LED and an integrated photon detector to
provide electrical insulation between input and output.
Separate connections for the photo-diode bias and output
transistor collector increase the speed up to a hundred
times over that of a conventional photo-transistor coupler by
reducing the base-collector capacitance.
The HCPL-M452 is designed for high speed TTL/TTL
applications. A standard 16 mA TTL sink current through the
input LED provides enough output current for 1 TTL load
and a 5.6 kΩ pull-up resistor. CTR of the HCPL-M452 is
19% minimum at IF = 16 mA.
The HCPL-M453 is an HCPL-M452 with increased common
mode transient immunity of 15,000 V/µs minimum at
VCM = 1500V guaranteed.

photo-transistor type
CAUTION! The small device geometries inherent to the design of this bipolar component increase the component's
susceptibility to damage from electrostatic discharge (ESD). Take normal static precautions in handling and
assembly of this component to prevent damage and/or degradation which may be induced by ESD.
