UT912D

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 VT pin also goes high to 

indicate a valid transmission.
