Overview

The LC75842E is a 1/2 duty general-purpose LCD display

driver for applications such as microprocessor-controlled

electronic tuning. It can drive up to 54 segments directly.

Features

• 1/2 duty, 1/2 bias drive of up to 54 segments

• Serial data input supports CCB* format communication

with the system controller.

• Backup function which is based on a power saving

mode and all segments off functions that are controlled

by serial data.

• High generality, since display data is displayed directly

without decoder intervention.

• The display can be forced to the off state with the INH

pin.

• RC oscillator circuit
