The TWH9236/9238 miniature radio remote control transmitting/receiving component contains a key chain type transmitter and a miniature receiver. For the launch component TWH9236, the operating voltage is supplied by a Az3 type button cell, the voltage is 1.5V, the operating current is smaller than 6mA. But the operating voltage of the receiving component TWH9238 is 6V, the static current is only 1.5mA. The output voltage of the data output port is 5V, the maximum output current is 1.8mA, so it can drive the transistor directly. The remote control distance is more than 50m. The TWH9238 can form the 3 and 4-channel remote control transmitting/receiving circuits, also it can be expanded to the 9 and 16-channel remote control circuit.
