Working voltage range: 2.5v ~ 5v
The working current of Tx-2 is 2max-2 and the driving current is 1mA.
TX-2/RX-2 is a special remote control integrated circuit. Can form an independent control circuit, with five infrared remote control or radio remote control functions, which can remotely control toy cars, various household appliances and lighting lamps.
TX-2/RX-2 remote control integrated circuit has the following characteristics: (1) is manufactured by CM05 process, with low static power consumption, few peripheral components, wide application range of power supply voltage (VCC = 2.5 ~ 5. 0v), and stable and reliable operation. (2) It has the control function of five independent remote switches. Since the remote control transmitting integrated circuit can output two kinds of output signals: carrier coded signal and carrier-free coded signal, not only five independent radio remote controls can be realized, but also five independent infrared remote controls can be conveniently realized through corresponding radio frequency circuits. (3) TX-2 has automatic shutdown function, which is convenient for the design of remote control transmitter and can save energy. (4) Multi-channel (multiple of 5) remote control can be conveniently realized by connecting multiple TX-2s and multiple RX-2s in parallel.
