Description

The HCPL-4502/HCPL-2503, 6N135/6 and HCPL-2530/HCPL-

2531 optocouplers consist 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.

An internal noise shield provides superior common mode rejec-

tion of 10kV/µs. An improved package allows superior insulation

permitting a 480 V working voltage compared to industry stan-

dard of 220 V.
