DECODERS FOR REMOTE
CONTROLLER
 DESCRIPTION
The UTC UT912D of CMOS LSIs for remote control system
applications are paired with UTC UT912E (refer to the
encoder/decoder cross reference table) and is capable of
decoding information which consists of N address bits and 12-N
data bits. For proper operation, a pair of encoder/decoder with the
same number of addresses and data format should be chosen.
The UTC UT912D also is arranged to provide 8 address bits and
4 data bits.
The decoders receive serial addresses and data from a
programmed UTC UT912E of encoders that are transmitted
together with the header bits by a RF or an infrared transmission
medium upon receipt of a trigger signal. If no error or unmatched
codes are found, the input data codes are decoded and then
transferred to the output pins. The V_T pin also goes high to
indicate a valid transmission.
