Optocoupler/LED/nixie tube/photoelectric device

The HMHA281, HMHA2801 series consist of a Gallium Arsenide Infrared Emitting Diode driving a silicon phototransistor in a compact 4-pin miniature flat encapsulation. The lead spacing is 1.27mm.

The MOC303XM and MOC304XM devices consist of an AlGaAs infrared light-emitting diode optically coupled to a monolithic silicon detector, performing the function of a zero voltage crossing double-sided triple driver. These devices are suitable for triacs in logic system interfaces of equipment powered from the 115V AC line, such as teletypewriters, CTRs, solid state relays, industrial controls, printers, motors, solenoid valves, and consumer equipment.

The H11LXM series features a high-speed integrated circuit detector optically coupled to a gallium arsenide infrared light-emitting diode. The output incorporates a Schmitt trigger, providing hysteresis for noise immunity and pulse shaping. The detector circuit is optimized for operational simplicity and utilizes an open collector output for maximum application flexibility.
