MN3112SA
Vertical Driver for Video-Camera CCD Area-Image-Sensor
Overview
The MN3112SA is a vertical driver LSI incorporating
four vertical driver channels and one sub driver channel
for a 2-dimensional interline CCD image sensor.
The MN3112SA enables low current dissipation and
the part reductions.
