80 SEGMENT DRIVER FOR DOT MATRIX LCD S6A2067 INTRODUCTION The S6A2067 is a LCD driver lC which is fabricated by low power CMOS technology.

Basically this lC consists of 40 x 2 bit bi-directional shift register, 40 x 2 bit data latch and 40 x 2 bit LCD driver (refer to Figure 1).

This lC can be used as segment driver.

FUNCTION Dot matrix LCD driver with 80 channel output.

Input / Output signal - Output: 40 x 2 channel waveform for LCD driving - Input: Serial display data an
