General Description

The 2¹²decoders are a series of CMOS LSIs for remote

control system applications. They are paired with

Holtek¢s 2¹²series 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 2¹²series 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 2¹²series 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-
