Dot-matrix LCD Drivers
Overview
The LC7940YD and LC7941YD are segment driver ICs
for driving large, dot
–
matrix LCD displays. They read 4
–
bit parallel or serial input, display data from a controller
into an 80
–
bit latch, and then generate LCD drive signals
corresponding to that data.
The LC7940YD and LC7941YD feature mirror
–
image pin
assignments, allowing them to be used together to increase
component density. They are designed to be used with the
LC7942YD common driver to drive large LCD panels.
