PT2272
DESCRIPTION
PT2272 is a remote control decoder paired with PT2262 utilizing CMOS Technology. It has 12 bits of
tri-state address pins providing a maximum of 531,441 (or 312) address codes; thereby, drastically
reducing any code collision and unauthorized code scanning possibilities. PT2272 is available in
several options to suit every application need: varai ble number of data output pins, latch or momentary
output type.

Each pin can be set to “0”, “1”, or “f” (floating).
Code Address Pin Nos. 6 ~11/Data Pin Nos. 5 ~ 0.
These six pins are used as higher address input
bits or data output pins depending on the version
(type) of PT2272 used.
When used as address inputs, these pins are
I/O
tri-state input pins and each pin can be set to “0”,
“1”, or “f” (floating).
When used as output pins, these pins are driven to

that was received matches the address setting at
the address input pins, and (2) the corresponding
