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.
