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