Video Camera IC
MN3114
Vertical Driver (8 channels) for CCD Area Image Sensors
■ Overview
The MN3114 is an 8-channel vertical driver for twodimensional 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 consumption and parts counts in end products.
■ Features
•
Vertical driver block:
Consists of level shifters and 2-value/3-value output
driver circuits.
•
SUB driver block:
Consists of a level shifter and a 2-value output driver
circuit.
•
Package: 24-pin SSOP
■ Applications
•
Digital still cameras, video cameras
