LC7942KD

Overview

The LC7942KD is a common driver LSI for driving large dot-matrix LCD displays. It features a built-in 64-bit

bidirectional shift register and a 4-level LCD driver. It can also be connected in cascade to increase the number of bits.

The LC7942KD is designed to be used with LC7940KD (QIP100D) or LC7941KDR (QIP100DR) segment drivers to

drive large LCD panels.

Features

• 64 built-in LCD display drive circuits

• 1/64 to 1/128 display duty cycle

• Input/outputs for cascade conection

• Bias supply voltages can be supplied externally

• Operating supply voltage and ambient temperature:

2.7 to 5.5V logic supply (VDD) at Ta = -20 to +85°C

8 to 20V LCD supply (VDD-VEE) at Ta = -20 to +85°C

• CMOS process

• package: QIP80D
