LS7339 General 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 OFFthe 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 connected to the OSCILLATOR input. Activation of the OFF input will always turn the triac OFF. The two ICs differ only in the width of theTRIGpulse used to trigger the triac. (See I/O Description, Pin 4.)
The triac remains On for the duration of the Timer which is controlled by an external R-C connected to the OSCILLATOR input. Activation of the OFF input will always turn the triac OFF. The two ICs differ only in the width of theTRIGpulse used to trigger the triac. (See I/O Description, Pin 4.)
