LS7338 - DELAYED-OFF LIGHT SWITCH WITH PROGRAMMABLE ON-TIMER

Description

The LS7338 is a monolithic MOS integrated circuit designed to turn a triac On and Off in a Power Switch for Incandescent Lighting.

Activation of SENSE or SLAVE inputs turns the triac On and starts a timer.

Features

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