32 CH COMMON DRIVER FOR DOT MATRIX LCD
INTRODUCTION
64 QFP
KS0105 is a LCD driver LSI which is fabricated by low power CMOS
high voltage process technology. This device consists of timing
generator circuit, 32 bit shift register and 32 bit driver.
FUNCTION
• Dot matrix LCD common driver with 32 channel output
• Input /Output signal
- Input: bias voltage (V1, V2, V5, V6, VEE)
- Output; 32 channel waveform for LCD driving and segment
driver control pulse.
FEATURE
• Power supply voltage: +5V±10%
• Supply voltage for display: 0~-5.5V(VEE)
• Applicable LCD duty; selectable 7 kinds
(1/8, 1/12, 1/16, 1/24, 1/32, 1/48, 1/64)
