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
* 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
