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.
