Never allow a stress to exceed the values listed under "Absolute Maximum Ratings", otherwise the device  
would suffer from a permanent damage. Nor is a stress at the listed value be allowed to persist over a period,  
since an extended exposure to the absolute maximum rating condition may also affect the reliability of the device,  
if not causing a damage thereof.

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. OVER•CURRENT 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  
Data code =

TX•5B output pin (SO) has an inverted phase with  
TX•5B F34 is sequential trigger pin, it controls  
RX•5B input (SI). If TX•5B&RX•5B are connected F3&F4 output at the receiver.  
without using a RF module, an inverter has to be  
inserted between these 2 pins, as shown below.

HANDLING MOS DEVICES:  
Electrostatic charges can exist in many things. All of our MOS devices are internally protected against  
electrostatic discharge but they can be damaged if the following precautions are not taken:  
· Persons at a work bench should be earthed via a wrist strap.  
· Equipment cases should be earthed.  
· All tools used during assembly, including soldering tools and solder baths, must be earthed.  
· MOS devices should be packed for dispatch in antistatic/conductive containers.
