DELAYED-OFF LIGHT SWITCH WITH PROGRAMMABLE ON-TIMER

The LS7338 is a 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 The Triac remains On for the duration of the Timer which is controlled by an external R-C connected to the Oscillator input. When Time- out occurs, the power delivered by the Triac is stepped down by 31% and then slowly reduced to Off over a fixed period of time. By LSI Computer Systems, Inc.
