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.

PT2272
FUNCTION DESCRIPTION
PT2272 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, PT2272
drives - (1) the data output pin(s) whose corresponding data bit(s) is then decoded to be a “1” bit, and
(2) the VT output -- to high voltage (high state).
RF OPERATION
CODE BITS
A Code Bit is the basic component of the encoded waveform, and can be classified as either an AD
(Address/Data) Bit or a SYNC (Synchronous) Bit.
Address/Data (AD) Bit Waveform
An AD Bit can be designated as Bit “0”, “1” or “f”, if iits in low, high or floatni g state respectively. One bit
waveform consists of 2 pulse cycles. Each pulse cycle has 16 oscillating time periods. For further
details, please refer to the diagram below:
