The M50120P is designed as one kind of infrared remote control launch circuit that can be used in TVs. The internal circuit is composed of the input circuit, the scanning circuit, the type coding circuit, the oscillator, the timing signal generator, the instruction decoder, the data controller, the D/A controller, the D/A converter and the program controller. Features It uses the aluminum gate CMOS technology;When it uses the single power operating mode, the power voltage is wide (Vcc=8-14V);The oscillation circuit is connected with the ceramic or the LC component to be used as the resonant component, the transmitting signal uses the pulse code modulation mode;It can receive 36 kinds of instructions, and it has nine direct key functions;The simple single frequency receiving system;30-pin dual-row DIP package;The matching models are M51231P, M58486AP or the M50118P.
