... Remote Control Decoder IC DESCRIPTION PT2294 is a remote control decoder paired with PT2264 utilizing CMOS Technology. It has 12 bits of tri-state address pins providing a maximum of 531,441 (or 3 reducing any code collision and unauthorized code scanning possibilities. PT2294 is available in several options to suit every application needs: variable number of data output pins, latch or momentary output type ...

... Code Address Pin Nos 11/Data Pin Nos These four pins are used as higher address input bits or data output pins depending on the version (type) of PT2294 used. When used as address inputs, these pins are tri-state input pins and each pin can be set to “0”, “1”, or “f” (floating). ...

... Remote Control Decoder IC FUNCTION DESCRIPTION PT2294 decodes the waveform received and fed into the DIN pin. The waveform is decoded into code word that contains the address, data and sync bits. The decoded address bits are compared with the address set at the address input pins. If both addresses match for 2 consecutive code words, PT2294 drives -- (1) the data output pin(s) whose corresponding data bit(s) is then decoded “ ...

... The built-in oscillator circuitry of PT2294 allows a precision oscillator to be constructed with only an external resistor. For the PT2294 to decode correctly the waveform that was received, the oscillator frequency of PT2294 must 30) times that of the transmitting PT2264 good practice to center the PT2294 oscillator frequency in this window to gain best window margin at both sides ...

... Suggested oscillator resistor values are shown below. VAILD TRANSMISSION When PT2294 receives a transmission code word, it initially checks whether this is a valid transmission. For a transmission to be valid, (1) it must be a Complete Code Word, and (2) the Address Bits must match the Address Setting at the Address Pins. After two consecutive valid transmissions, PT2294 (1) www ...

... The latch type (PT2294-Lx) activates the data out during transmission and this data is sustained in the memory until another data is inputted or entered. A momentary type (PT2294-Mx), on the other hand, activates the data out only during transmission. In the momentary type, the data does not remain in the memory after the transmission is completed ...

If there is no signal received, it remains in the Stand-By Mode; otherwise, the address bits received are compared with the address configuration of the pins. ...
