Dot Character VFD Controller/Driver IC
PT6314
DESCRIPTION
PT6314 is a VFD Controller/Driver IC utilizing CMOS technology providing 80 segment outputs and 24
grid outputs. It supports dot matrix displays of up to 16 columns x 2 lines, 20 columns x 2 lines or 24
columns x 2 lines. PT6314 also features a character generator ROM which stores 240 x 5 x 8 dos
characters. Pin assignments and application circuits are optimized for easy PCB layout and cost
saving advantages.
