MSM9004-01/02

1/3, 1/4 DUTY LCD DRIVER WITH 4-DOT COMMON DRIVER AND 49-DOT SEGMENT DRIVER

GENERAL DESCRIPTION

The MSM 9004-01/02 is an LCD driver for dynamic display with a 1/3 or 1/4 duty select function.

When the 1/3 duty is selected, it can display up to 147 segments, and when the 1/4 duty is

selected, up to 196 segments.
