40 CH SEGMENT/COMMON DRIVER FOR DOT MATRIX LCD S6A0065
INTRODUCTION
The S6A0065 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. (refer to Fig 1) 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.
• Input / Output signal
- Output: 20 x 2 channel waveform for LCD driving
- Input: Serial display data and control signal from the controller LSI.
Bias voltage (V1-V6)
FEATURES
