LS7340 - AUTO SHUT-OFF AC POWER SWITCH WITH PROGRAMMABLE TIMER

Description

The LS7339 and LS7340 are monolithic MOS integrated circuits designed to turn a triac On and Off in a Power Switch for AC loads.

Activation of the ON input will always turn the triac On and start a Timer.

Features

  • Phase-Lock Loop Synchronization allows use in Wall Switch.
