General Description

The 312encoders are a series of CMOS LSIs for remote control system applications. They are capable of encod ing 12 bits of information which consists of N address
bits and 12-N data bits. Each address/data input is ex­ternally trinary programmable if bonded out. They are otherwise set floating internally. Various packages of
12
the 3
encoders offer flexible combinations of pro-

·
Built-in oscillator needs only 5% resistor
·
Easy interface with an RF or an infrared transmission medium
·
Minimal external components
·

grammable address/data which meet various appli cations. 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. A TE (HT6010) or a DATA (HT6012/HT6014) trigger can be selected for application flexibility.
