Dot-matrix LCD Drivers

Overview

The LC7940YC and LC7941YC are segment driver ICs

for driving large, dot

bit parallel or serial input, display data from a controller

into an 80 bit latch, and then generate LCD drive signals

–matrix LCD displays. They read 4–

–

corresponding to that data.

The LC7940YC and LC7941YC feature mirror–image pin

assignments, allowing them to be used together to increase

component density. They are designed to be used with the

LC7942YC common driver to drive large LCD panels.

Features

• 80 built

• 1/8 to l/128 display duty cycle

• Serial or 4 bit parallel data input
