The TX2B and RX2B are a matched pair of CMOS LSI chips designed for wireless remote control applications [citation:3][citation:5]. The TX2B serves as the encoder/transmitter IC, while the RX2B functions as the decoder/receiver IC. Together they provide 5channel control (Forward, Backward, Left, Right, and Turbo) for remotecontrolled cars, robots, and automation projects [citation:3][citation:5].

The TX2B encodes button presses into a digital signal. This encoded signal is then modulated onto an RF carrier (typically 27MHz) using external RF circuits [citation:1][citation:5]. The RX2B receives and demodulates the signal, then decodes it to activate corresponding output pins [citation:5].
Transmitter Side: Push buttons → TX-2B encodes → RF transmitter circuit → Antenna
Receiver Side: Antenna → RF receiver circuit → RX-2B decodes → Output pins
