Overview

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