LC7941KDR 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

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

VDD-VEE (LCD block): 8 to 20V/-20 to +85°C

• CMOS process

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