General Description
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.
