PT8A9701 (Obsolete)

Product 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.

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
