PT6332

DESCRIPTION

PT6332 is a VFD driver IC driven on 1/2 to 1/3 duty factor. It can drive up to 168 segments. 56 segment

output lines, 3 grid output lines, 4 general purpose output lines, control circuit, key scan circuit are all

incorporated into a single chip to build a highly reliable peripheral device for a single chip micro

controller. Pin configuration and application circuit are optimized for easy PCB layout and cost saving

advantages.
