General Description

The 2¹²encoders 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

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 ap-

plication flexibility of the 2¹²series of encoders.

The HT12A additionally provides a 38kHz car-

rier for infrared systems.
