General Description
The 2
control system applications. They are capable of encod-
ing information which consists of N address bits and
12 N data bits. Each address/data input can be set to
one of the two logic states. The programmed ad-
dresses/data are transmitted together with the header

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 2
ries of encoders. The HT12A additionally provides a
38kHz carrier for infrared systems.
