LC79430KNE-E

Display Drivers Overview

The LC79430KNE-E is a CMOS LSI dot-matrix LCD common driver manufactured by onsemi, formerly Sanyo. It integrates an 80-bit bidirectional shift register and a 4-level LCD drive circuit. The device supports display duty selection from 1/64 to 1/256 and allows bit expansion via cascade connection input/output pins. It operates with a logic supply voltage of 2.7V to 5.5V and an LCD section supply voltage (VDD-VEE) of 12V to 32V across a temperature range of -20°C to +85°C. The component is housed in a 100-pin flat plastic package.
