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.

tional operation should be restricted to the limits in the Electrical Characteristics tables or
Pin Descriptions section.
This device contains protection circuitry to
guard against damage due to high static
voltages or electric fields; however, it is ad-
vised that precautions be taken to avoid
application of voltage higher than maximum
rated voltages to this high–impedance circuit.
For proper operation it is recommended that
Vin and Vout be constrained to the range VSS
(Vin or Vout) VDD.
Unused inputs must always be tied to an
appropriate logic voltage level (e.g., either VSS
or VDD).
