LC79400D Description
EN4346B 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 mon driver LC7943D (QIP80D) as well as LC79430D (QIP100D) and LC79431D (QIP100D) to drive a widescreen LCD...
