Introduction

The NT7063B is a LCD driver LSI which is fabricated by low power CMOS technology. Basically this LSI

consists of 40 x 2 bit bidirectional shift register, 40 x 2 bit data latch and 40 x 2 bit LCD driver (refer to Fig 1).

This LSI can be used segment driver.

Function

• Dot matrix LCD driver with 80 channel output.
