Video Camera IC
MN3114
Vertical Driver (8 channels) for CCD Area Image Sensors
s
Overview
The MN3114 is an 8-channel vertical driver for two-
dimensional interline CCD area image sensors that also
integrates a single SUB driver channel on the same chip.
Adoption of this IC can reduce both power consump-
tion and parts counts in end products.
