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
12N data bits. Each address/data input can be set to
one of the two logic states. The programmed addresses/
data are transmitted together with the header
bits via an RF or an infrared transmission medium upon
receipt of a trigger signal. The capability to select a TE
trigger on the HT12E or a DATA trigger on the HT12A
further enhances the application flexibility of the 212 series
of encoders. The HT12A additionally provides a
38kHz carrier for infrared systems.
