General Description  
The 212 decoders are a series of CMOS LSIs for remote  
control system applications. They are paired with  
Holtek¢s 212 series of encoders (refer to the encoder/de-  
coder cross reference table). For proper operation, a  
pair of encoder/decoder with the same number of ad-  
dresses and data format should be chosen.  
ously with their local addresses. If no error or un-  
matched 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.  
The 212 series of decoders are capable of decoding  
informations that consist of N bits of address and 12-N  
bits of data. Of this series, the HT12D is arranged to pro-  
vide 8 address bits and 4 data bits, and HT12F is used to  
decode 12 bits of address information.  
The decoders receive serial addresses and data from a  
programmed 212 series of encoders that are transmitted  
by a carrier using an RF or an IR transmission medium.  
They compare the serial input data three times continu-
