CMOS IC

Dot-Matrix LCD Drivers

Overview

The LC7940KD and LC7941KDR are segment driver LSIs for driving large, dot-matrix LCD displays. They read 4-bit

parallel or serial input, display data from a controller into an 80-bit latch, and then generate LCD drive signals

corresponding to that data. The LC7940KD and LC7941KDR feature mirror-image pin assignments, allowing them to be

used together to increase component density. They are designed to be used with the LC7942KD (QIP80D) common

driver to drive large LCD panels.

Features

• 80 built-in LCD display drive circuits

• 1/8 to 1/128 display duty cycle

• Serial or 4-bit parallel data input

• Chip disable for low power dissipation for large-sized panels

• Bias supply voltage can be supplied externally

• Operating supply voltage and ambient temperature

(logic block): 2.7 to 5.5V/-20 to +85°C

-V (LCD block): 8 to 20V/-20 to +85°C

DD EE

• CMOS process

• Package: QIP100D(LC7940KD)/QIP100DR(LC7941KDR)

Any and all SANYO Semiconductor products described or contained herein do not have specifications

that can handle applications that require extremely high levels of reliability, such as life-support systems,

aircraft's control systems, or other applications whose failure can be reasonably expected to result in

serious physical and/or material damage. Consult with your SANYO Semiconductor representative

nearest you before usingany SANYO Semiconductor products described or contained herein in such

applications.

SANYO Semiconductor assumes no responsibility for equipment failures that result from using products

at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition

ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor

products described or contained herein.
