Overview
HCPL-M452/HCPL-M453 Small Outline, 5-Lead, High-Speed Optocouplers Data Sheet Description The Broadcom® HCPL-M452/HCPL-M453 small outline high CMR, high-speed, diode-transistor optocouplers are single-channel devices in a five-lead miniature footprint.
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 photodiode bias and output transistor collector increase the speed up to a hundred times over that of a conventional phototransistor 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.
Features  Surface mountable  Very small, low-profile JEDEC registered package outline  Compatible with infrared vapor phase reflow and wave soldering processes  Very high common mode transient immunity: 1,5000 V/µs at VCM = 1500V guaranteed (HCPL-M453)  High speed: 1 Mb/s  TTL compatible  Open collector output  Worldwide safety approval: – UL1577 recognized, 3750Vrms/1min – CSA approved  Lead-free option Applications  Line receivers: High common mode transient immunity (>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 slow phototransistor optocouplers  Replace pulse transformers: save board space a...
