TX-2B/RX-2C TOY CAR REMOTE CONTROLLER WITH FIVE FUNCTIONS DESCRIPTION The TX-2B/RX-2C is a pair of CMOS LSIs designed for remote controlled car applications. The TX-2B/RX-2C has five control keys for controlling the motions (i.e. forward, backward, rightward, leftward and the turbo function) of the remote controlled car. FEATURES TX-2B DIP-14 RX-2C TX-2BS RX-2CS * Wide operating voltage range (VCC=1.8V~5.0V when DC-DC is not used and VCC=1.0V~5.0V when DC-DC is used) * Low stand-by curren.
