Features
General Description
• The PT8A9701P works as the encoder and the
PT8A974P/974LP works as the decoder
• Nine output pins, 5 for forward, backward, left,
right and turbo functions, and 3 functional keys
• Operation power supply for PT8A9701: 3V to 12V
(with series resistor)
• Auto power-off if no key pressed (PT8A9701P)
• Motor current limit to meet toy safety standard
HD271 (PT8A974P/974LP)
• Low operating current
• On-chip oscillator with an external resistor
• On-chip reversing amplifiers
• Built-in 3.7V Zener (Vz) (PT8A974P) and 3.1V
Zener (Vz) (PT8A974LP)
• Few external components needed
The PT8A9701P and PT8A974P/974LP is a pair of
CMOS LSIs designed for remote controlled toy car
application. They have eight control keys for
controlling the corresponding motion, i.e., forward,
backward, left, right, turbo and 3 functional keys, of
the remote controlled car. They also have ‘Forward
(Backward)’ and ‘Turbo’ combination application.
