Overview
The LC79401KNE is a 80-outputs segment driver LSI for graphic dot-matrix liquid crystal display systems.
The LC79401KNE latches 80 bits of display data sent from a controller using a 4-bit parallel transfer technique and
generates LCD drive signals. When combined as a kit with common driver, either the LC79430KNE (QIP100E), the
LC79401KNE can drive large screen LCD panels.
Features
Incorporates LCD drive circuits for 80 bits of display.
Supports display duties from 1/64 to 1/256
The provision of a chip disable pin supports power reduction in large-scale panels.
Allows external provision of the bias power supply
Operating supply voltage/operating temperature
VDD (logic block) : 2.7 to 5.5V/-20 to +85°C
VDD-VEE (LCD block) : 12 to 32V/-20 to +85°C
Data transfer clock : 6.0MHz (max), bidirectional shifting supported
Data input : 4-bit parallel input
CMOS process
100-pin flat plastic package (QIP100E)

O Connect to the CDI pin on the next chip when cascade connection is used.
Input that controls the O1 to O80 output pins. During periods when this pin
I
Is low, the O1 to O80 output pins output the V1 level. See the truth table.
LCD drive outputs
The output level are determined by the combination of the output the data,
The M signal, and The DISPOFF pin as shown in the table.
