REMOTE CONTROLLER WITH SEVEN FUNCTIONS
DESCRIPTION
The TX-5B/RX-5B are a pair of CMOS LSIs designed for remote controlled car applications. They have nine control keys controlling the motions (i.e. forward, backward, rightward, leftward, trigger 1-trigger 4 functions and the turbo function) of the remote controlled car. The TX-5B is housed in DIP-16 package, and the RX-5B is housed in DIP-22 package.

COMMENT
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
TX-5B/RX-5B
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 = F B T R L F1 F3 F4 F2
F = Forward F1 = Function1
B = Backward F2 = Function2
T = Turbo F3 = Function3
R = Right F4 = Function4
L = Left
parity code = for parity check end code = for (latch data) * Data code can be any combination of F,B,T,R,L,F1,F2,F3,F4 except for F&B, R&L, F3&F4.

Note: (1) In the table, blank=F0. Rows from "FUNCTION1" to "RIGHT+FUNCTION1" (the last row) are similar for FUNCTION2, FUNCTION2, FUNCTION2. Thus, we can see from the table that we have more than 50 states of function combinations from 8 control keys. (2) H = high level. (3) LRTD pin functions as an option pin for LEFT/RIGHT turbo disable. Please refer to the following table.
