Sanyo LC75842M Specifications

Any and all SANYO 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 representative nearest you before using
any SANYO products described or contained herein in such applications.

SANYO 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 products described or contained
herein.

Overview

The LC75842E and LC75842M are 1/2 duty general­purpose LCD display drivers for applications such as
microprocessor-controlled electronic tuning. They 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
