TX-2B/RX-2C  
TOY CAR REMOTE CONTROLLER WITH FIVE FUNCTIONS  
DESCRIPTION  
TX-2B  
DIP-14  
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.  
TX-2BS  
RX-2CS  
RX-2C  
FEATURES  
* Wide operating voltage range (V =1.8V~5.0V when DC-DC is  
CC  
not used and V =1.0V~5.0V when DC-DC is used)  
CC  
DIP-16  
SOP-16  
* 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 ;

The operator must put on wrist strap which should be earthed to against electrostatic.  
Equipment cases should be earthed.  
All tools used during assembly, including soldering tools and solder baths, must be earthed.  
MOS devices should be packed in antistatic/conductive containers for transportation.  
Note：Silan reserves the right to make changes without notice in this specification for the improvement of the design and performance.  
Silan will supply the best possible product for customers.
