==1. Description==
HX2272 / 2262 is a remote control for decoding circuit. The chipset using CMOS technology. The pin-site data and coding through a serial code for the application of RF or IR model. HX2272 have up to three of the 12-bit address pins provide 531,441 addresses code, which greatly reduce any wrong code and the possibility Series yards. Meanwhile HX2272 counterpart different applications have different options: multiple data output pin; Latch output; Instant output.
 
==2. Features==
*The low-power CMOS technology
*SNR up to 12 three-pin-code addresses can
* 6 Data-pin wide
*Operating voltage range: 3 to 18V
*Instantaneous output latch
*DIP package
*RC oscillator
 
==3 Applications==
*Car security system home security / automation system
*Garage door controller
*Fans remote home security / automation systems
*Industrial remote control
*Toys with remote control
 
==4. Pinout==
