Overview

The LC79400D is a large-scale dot matrix LCD segment

driver LSI. Display data transferred from the controller

(4-bit parallel format) is processed through 80-bit

latching and a LCD drive signal is generated. The

LC79400D can be used in conjunction with common

driver LC7943D (QIP80D) as well as LC79430D

(QIP100D) and LC79431D (QIP100D) to drive a wide-

screen LCD panel.

Features

• On-chip LCD drive circuit (80 bits)

• Display duty selection ranging from 1/64 to 1/256

• Supports use of chip disable pin for lower large panel

• Supports externally supplied bias voltage

• Operating power supply voltage/operating temperature

• Data transfer clock provides maximum 3.0 MHz and

• 4-bit parallel data input

• CMOS process

• 100-pin flat plastic package
