1. 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-M453-500E is an HCPL-M452 with increased common mode transient immunity of 15,000 V/µs minimum at VCM = 1500V guaranteed.
