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
