CMOS LSI
LC79401KNE
Dot-Matrix LCD Drivers
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
