SC2272
SC2272 Description:(Compatible:PT2272)
SC2272 is a remote control decoder paired with SC2262and SC2260 utilizing
CMOS technology. It has 12 bits of tri-state address pins providing a maximum
of 531,441 address codes; thereby, drastically reducing any code collision
and unauthorized code scanning possibilities.SC2272 is available in several
options to suit every application need: variable number of data output pins,
latch or momentary output type.
SC2272 Features:(Compatible:PT2272)
Low power consumption
Wide operating temperature range: -30～70 °C
Up to 12 tri-state code address pins
Up to 6 data pins
Single resistor oscillator
Latch or momentary output type
SC2272 Applications:(Compatible:PT2272)
Home/motor car security system Garage door controller
Remote fan controller Remote control toys
SC2272 Pin Configuration:(Compatible:PT2272)

SC2272 Functions description:(Compatible:PT2272)
SC2272 decode signal from Din pin. If the code from SC2262 valid same as
SC2272 set and received two times,the data pins will be “1”or “0” same as
SC2262 data pins and will drive the confirm pin Vt to “1”. The SC2272 code same
as SC2262 means:
1、the address pin state of SC2272 same as SC2262 .
2、the oscillator frequency of SC2272 coordinate SC2262
SC2272 Code Description:(Compatible:PT2272)
1、There are 12 A/D BIT and 1 SYNC BIT in one frame
