REMOTE CONTROLLER WITH FIVE
FUNCTIONS
DESCRIPTION
The TX-2B/RX-2B is a pair of CMOS LSIs designed for remote
controlled car applications. The TX-2B/RX-2B 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=1.5~5.0V)
* Low stand-by current
* Auto-power-off function for TX-2B
* Few external components are needed
