The M50142P is designed as one kind of infrared remote control launch large-scale circuit that can be used in the TVs. The internal circuit is composed of the keyboard input encoder, the instruction decoder, the oscillator, the timing signal generator, the scanning signal generator, the coding modulator and the output buffer. Features It uses the aluminum gate CMOS technology;When the keyboard button is not pressed, the oscillator will stop oscillating to reduce the power consumption;When the remote control launch circuit is operating, the current is about 15mA, when the remote control launch circuit is not operating, the current is about 10A;If you press any two or more buttons together, the output is in the low level state;It is in the 24-pin dual-row DIP plastic package;The matching model is uPC1373H.
