PT8A9701

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

   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 Forwar (Backward) and Turbo combination application.
