General Description
The 318 encoders are a series of CMOS LSIs for
remote control system applications. They are
capable of encoding 18 bits of information
which consists of N address bits and 18-N data
bits. Each address/data input is externally
trinary programmable if bonded out. It is other-
wise set floating internally. Various packages of
the 318 encoders offer flexible combinations of
programmable address/data to meet various
application needs. The programmable ad-
dress/data is transmitted together with the
header bits via an RF or an infrared transmis-
sion medium upon receipt of a trigger signal.
The capability to select a TE trigger type or a
DATA trigger type further enhances the appli-
cation flexibility of the 318 series of encoders.
