Introduction

The NT7065B is a LCD driver IC which is fabricated by low power CMOS technology. Basically this IC

consists of 20 x 2 bit bi-directional shift register, 20 x 2 bit data latch and 20 x 2 bit driver. This IC can be used

as common or segment driver.

Function

． Dot matrix LCD driver with 40 channel output.

． Selects function to use common/segment drivers simultaneously.
