General Description
The 2
12
decoders are a series of CMOS LSIs for
remote control system applications. They are
paired with Holtek s 2
series 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.
The decoders receive serial addresses and data
from a programmed 2
series 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
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 2
12
series 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.
Features
