Description

The MOC303XM and MOC304XM devices consist of a AlGaAs

infrared emitting diode optically coupled to a monolithic silicon

detector performing the function of a zero voltage crossing bilat-

eral triac driver.

They are designed for use with a triac in the interface of logic

systems to equipment powered from 115 VAC lines, such as

teletypewriters, CRTs, solid-state relays, industrial controls,

printers, motors, solenoids and consumer appliances, etc.
