The TC1948P is designed as one kind of infrared remote control launch circuit that can be used in the video tape recorder application. The internal circuit is composed of the keyboard input circuit, the oscillator, the timing signal generator, the code signal generator, the decoder, the synchronous/single pulse signal generator and the output signal. The difference between the M50115P, M50115AP, M50115BP and M50115CP is the identification number. Features CMOS technology, the power consumption is low.The power supply voltage operating range is wide, and it can work in low voltage.16-pin dual-row DIP plastic package. Function description This oscillator can be connected with the LC resonant circuit and the ceramic filter to produce the reference signal.The oscillator will stop working when the button is not pressed to reduce the power consumption.
