PT6579

General Purpose LCD Driver IC

DESCRIPTION

FEATURES

PT6579 is an LCD Driver IC which can drive up to 200

segments. It can be used for frequency display in

microprocessor-controlled radio receiver and in other

display applications. PT6579 supports both 1/3 duty,

and 1/4 duty drive. Pin assignment and application

circuit are optimized for easy PCB layout and cost

saving advantages.
