TX-6B/RX-6B TOY CAR REMOTE CONTROLLER WITH SEVEN FUNCTIONS DESCRIPTION The TX-6B/RX-6B are a pair of CMOS LSIs designed for remote controlled car applications. They have seven control keys controlling the motions (i.e. forward, backward, rightward, leftward, two function SOP-16 SOP-20 DIP-16 DIP-18 keys and the turbo function) of the remote controlled car. The TX-6B is housed in DIP-16 package, and the RX-6B is housed in DIP-18 package.

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.

The TX-6B/RX-6B have seven control keys controlling the motions (i.e. forward, backward, rightward, leftward, two function keys 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 overcurrent 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 500Hz, 3/4 duty F1="1" 500Hz, 1/4 duty F0="0" 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 = F B T R L F1 N N F2 F = Forward B = Backward T = Turbo R = Right L = Left F1 = Function1 F2 = Function2 N = No used code Parity code = for parity check End code = for (latch data) * Data code can be any combination of F,B,T,R,L,F1,F2, except for F&B, R&L.

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.
