Description
The MOC303XM and MOC304XM devices consist of a
GaAs infrared emitting diode optically coupled to a
monolithic silicon detector performing the function of a
zero voltage crossing bilateral 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.
