LS7339 AUTO SHUT-OFF AC POWER SWITCH WITH PROGRAMMABLE TIMER

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. The triac remains On for the duration of the Timer which is controlled by an external R-C conn.
