UT912E
ENCODER FOR REMOTE
CONTROLLER
DESCRIPTION
The UTC
UT912E
of CMOS LSIs for remote control
system applications is capable of encoding 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 addresses/data are transmitted together
with the header bits by a RF or an infrared transmission
medium upon receipt of a trigger signal.
