General Description

The 2¹²decoders are a series of CMOS LSIs for

remote control system applications. They are

paired with Holtek¢s 2¹²series of encoders (re-

fer to the encoder/decoder cross reference ta-

ble). For proper operation, a pair of

encoder/decoder with the same number of ad-

dresses and data format should be chosen.

their local addresses. If no error or unmatched

codes are found, the input data codes are de-

coded 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 decod-

ing informations that consist of N bits of ad-

dress and 12-N bits of data. Of this series, the

HT12D is arranged to provide 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 se-

rial input data three times continuously with
