HT600/680/6207 -- 3¹⁸ Series of Encoders (EOL)

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 otherwise set floating internally. Various packages of the 3¹⁸ encoders offer flexible combinations of programmable address/data to meet various application needs. The programmable address/data is transmitted together with the header bits via an RF or an infrared transmission medium upon receipt of a trigger signal. The capability to select a TE trigger type or a DATA trigger type further enhances the application flexibility of the 3¹⁸ series of encoders.
