TC9012 is a special off screen remote control code transmitter. It includes oscillator, divider timing
generator, system code latch, data storage, key scan input, key scan output, the carrier control and
output units. Its internal 8-bit system code setting can be achieved with 256 points while operating the
transmitter and the interfering transmitter. TC9012F shape pin map. TC9012F infrared emission
