Overview
The LC79400D is a large-scale dot matrix LCD segment
driver LSI. Display data transferred from the controller
(4-bit parallel format) is processed through 80-bit
latching and a LCD drive signal is generated. The
LC79400D can be used in conjunction with common
driver LC7943D (QIP80D) as well as LC79430D
(QIP100D) and LC79431D (QIP100D) to drive a wide-
screen LCD panel.
Features
• On-chip LCD drive circuit (80 bits)
• Display duty selection ranging from 1/64 to 1/256
• Supports use of chip disable pin for lower large panel
• Supports externally supplied bias voltage
• Operating power supply voltage/operating temperature
• Data transfer clock provides maximum 3.0 MHz and
• 4-bit parallel data input
• CMOS process
• 100-pin flat plastic package
