IR Remote Control Transmitter
CMOS
The MC44107 remote control transmitter converts a keyboard input into a
pulse code modulated signal suitable for infrared transmission to an appropriate
receiver. Its large command capacity, 512 commands, makes it highly suited to
remote control applications in TV, video, hi–fi, etc. The transmitter is an LSI
circuit realized in complementary MOS technology.
