Overview
318 Series of Encoders Features · · · · Operating voltage: 2.
4V~12V Low power and high noise immunity CMOS technology Low standby current Three words transmission · · · Built-in oscillator needs only 5% resistor Easy interface with an RF or infrared transmission media Minimal external components Applications · · · · Burglar alarm system Smoke and fire alarm system Garage door controllers Car door controllers · · · · Car alarm system Security system Cordless telephones Other remote control systems General Description The 3 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 18 the 3 encoders offer flexible combinations of 18 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 appli18 cation flexibility of the 3 series of encoders.
