General Description

The 3¹⁸encoders 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 3¹⁸encoders 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 3¹⁸series of encoders.
