HX2272 is a remote control decoder for decoding signals encoded by the [[HX2272 remote encoder 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.

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 HX2272 used. When used as address inputs, these pins are 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 VCC if (1) the address decoded from the waveform that was received matches the address setting at the address input pins, and (2) the corresponding data bits received is a “1” bit. Otherwise, they are driven to VSS.
