Features
* The PT8A9701 works as the encoder and the PT8A973/973L works as the decoder * Seven output pins, 5 for forward, backward, left, right and turbo functions, and 2 functional keys * Operation power supply for PT8A9701: 3V to 12V (with series resistor) * Auto power-off if no key pressed (PT8A9701) * Motor current limit to meet toy safety standard HD271 (PT8A973/973L) * Low operating current * On-chip oscillator with an external resistor * On-chip reversing amplifiers
* Built-in 3.7V Zener (Vz) (PT8A973) and 3.1V Zener (Vz) (PT8A973L) * Few external components needed * Pin to pin compatible with TX6/RX6
General Description
The PT8A9701 and PT8A973/973L is a pair of CMOS LSIs designed for remote controlled toy car application. They have seven control keys for controlling the corresponding motion (forward, backward, left, right, turbo and 2 functional keys) of the remote controlled car. They also have `Forward (Backward)' and `Turbo' combination application.
