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 2
12
) 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.
