NTE3049
Optoisolator
Zero Crossing TRIAC Driver
Description:
The NTE3049 consists of a gallium arsenide infrared emitting diode optically coupled to a monolithic
silicon detector performing the function of a Zero Voltage crossing bilateral triac driver.
It is designed for use with a triac in the interface of logic systems to equipment powered from 115 Vac
lines, such as teletypewriters, CRTs, printers, motors, solenoids, and consumer appliances.
