Overview
 The NT7108 is a LCD driver LSI with 64 channel outputs for dot matrix liquid crystal graphic display systems. 
This device consists of the display RAM, 64 bit data latch, 64 bit drivers and decoder logic. It has the internal 
display RAM for storing the display data transferred from a 8 bit micro controller and generates the dot matrix 
liquid crystal driving signals corresponding to stored data. The NT7108 composed of the liquid crystal display 
system in combination with the NT7107.
