Description

The HCPL4503M optocoupler consists of an AlGaAs

LED optically coupled to a high speed photodetector

transistor.

A separate connection for the bias of the photodiode

improves the speed by several orders of magnitude over

conventional phototransistor optocouplers by reducing

the base-collector capacitance of the input transistor.

The base of the phototransistor is not bonded out to a

pin for improved noise immunity.

An internal noise shield provides superior common

mode rejection of 15kV/μs minimum.
