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 and control signal pulse from the controller lC.
Bias voltage (V1 to V4)
FEATURES
