HT-12F - Holtek

HT-12F 2 12 Series of Decoders

The 2 decoders are a series of CMOS LSIs for remote control system applications. They are 12 paired with Holtek¢s 2 series of encoders (refer to the encoder/decoder cross reference tab l e ) . F or p r op er op er a t i on, a p a i r o f encoder/decoder with the same number of addresses and data format should be chosen. The decoders receive serial addresses .
