CMOS LSI
LC79400D
Dot Matrix LCD Driver
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.
