Remote Control Decoder  
PT2271A  
PT2271A is a remote control decoder paired with PT2261A utilizing CMOS  
Technology. It has 12 bits of two-state address pins providing a maximum of  
4096 (or 212) address codes; thereby, drastically reducing any code collision and  
unauthorized code scanning possibilities. PT2271A is available in several options  
to suit every application need : variable number of data output pins, latch or  
momentary output type.
