FUNCTION DESCRIPTION  
The TX•5B/RX•5B are a pair of CMOS LSIs designed for remote controlled car applications. The TX•5B/RX•5B  
have nine control keys controlling the motions (i.e. forward, backward, rightward, leftward, and trigger1••trigger4  
functions and the turbo function) of the remote controlled car.  
1. OVERCURRENT PROTECTION  
An Auto Shut•Off mechanism is built•in according to Toy Safety Requirement and effective during over•current  
situation in motor driver. The active high input applying to this Auto Shut•Off pin will turn off the motor. (VT pin,  
when unused, has to be connected to ground. The transfer point=1.4V)  
2. DATA FORMAT  
F1="1"  
500Hz, 3/4 duty  
F0="0"  
500Hz, 1/4 duty  
3. CODING METHOD  
3.1 When a trigger pin is triggered, its data code will correspond to the data format of "F1", while the remaining  
pins will have the data format of "F0".  
3.2. Data string: start code + data code +parity code + end code  
Start code = F1 F1 F1 F1 F0
