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 MO

MC44107 Features

* is its low standby current consumption

* typically less than 1 µA. For this reason the battery may be left continuously in circuit. As soon as a key is selected, the circuit switches to its active mode and enables the oscillator. To allow for accidental activation and/or key bounce, the circ
