HCPL-4534

Dual Channel, High Speed Optocouplers

Currently Viewing:

The Broadcom HCPL-4534, 2-channel, transistor optocoupler contains a pair of light emitting diodes and integrated photodetectors with electrical insulation between input and output.

Separate connection for the photodiode bias and output transistor collectors increase the speed up to a hundred times that of a conventional phototransistor coupler by reducing the base-collector capacitance.

It is available in an 8 Pin DIP. It is an HCPL-2531 with increased common mode transient immunity of 15,000 V/ms minimum at VCM = 1500 V guaranteed.
