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.
