Description

The 6N135M, 6N136M, HCPL4503M, HCPL2530M, and

HCPL2531M optocouplers consist of an AlGaAs LED optically

coupled to a high speed photodetector transistor for each channel.

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 HCPL4503M has no internal connection to the phototransistor

base for improved noise immunity. An internal noise shield provides

superior common mode rejection of up to 50,000 V/s.
