General Description
The 212 encoders are a series of CMOS LSIs for remote control system applications. They are capable of encoding information which consists of N address bits and 12-N data bits. Each ad-dress/data input can be set to one of the two logic states. The programmed addresses/data are transmitted together with the header bits
