HX2262 Remote encoder circuit

• HX2262 is equivalent to PT2262 - datasheet here

1. Description

HX2262/2272 is for a remote control decoder circuit, the chip using CMOS Technology Group. The pin-site data and coding through a serial code for the application of RF or IR model. HX2262 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.

2. Features

• 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

Pinout 18-lead package	Pinout 20-lead package	Pin name	Input/Output	Note
1 ~ 6	1 ~ 6	A0 ~ A5	I	# # 0 -5 yards address pins. HX2262 3 through 6 of this state to determine pin-0 - 5-coding waveform. Each pin can be home to "0" and "1" or "f" (vacant)
7 ~ 8 10 ~ 13	7 ~ 8 12 ~ 15	A6/D5 ~ A11/D0	I	# 6 # 11 yards address pins or # 5 # -0 data pins. HX2262 3 through 6 of this state to determine pin-6 - 11-bit coding waveform. When they used to address pins, respectively home to "0" and "1" or "f" (vacant). When they are used as data pins, the only home for the "0" or "1."
