Remote Control Decoder
PT 2272
PT 2272 is a remote control decoder paired with PT 2262 utilizing CMOS
Technology. It has 12 bits of tri-state address pins providing a maximum of
531,441 (or 3
12
) address codes; thereby, drastically reducing any code collision and
unauthorized code scanning possibilities. PT 2272 is available in several options
to suit every application need : variable number of data output pins, latch or
momentary output type.
