Optoisolators are devices used in electronics to isolate two circuits electrically and optically by providing an electrical output signal from a light input. The output of an optoisolator typically is a light-activated transistor that can be easily integrated into circuit designs. Optoisolators are particularly useful for providing protection against short circuits and overvoltage events, as well as for achieving feedback or communication between two circuits. The HMHAA280R3 is an optoisolator with transistor, photovoltaic output designed by Broadcom.

The HMHAA280R3 optoisolator includes a LED emitter and a photovoltaic output device with a Darlington transistor output and special dielectric construction. It is designed to provide maximum efficiency and reliability, and incorporates an integrated circuit with an input for the control signal and an output for the logic level voltage signal. The LED emitter is activated by the input control signal and provides a light signal that is received by the photovoltaic output device which switches the transistor output. The Darlington transistor provides an open collector output stage which is low impedance at both high and low levels of the control signal.
