CMOS IC
Dot-matrix LCD Driver
Overview
The LC7942YC is a common driver IC 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 LC7942YC is designed to be used with LC7940YC or
LC7941YC segment drivers to drive large LCD panels.
