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

* 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
