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 current * In order to be used in the low
voltage condition, the DC-DC is
added in RX-2C; you can decide whether to use DC-DC; the
voltage to turn on is 1.0V ; and the
voltage to work is 0.8V ; and the output
voltage is 3.0V ; * Auto-power-off function for TX-2B * Few external components are needed
