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.
- 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
