MN31121SA

CCD Image Sensor Vertical Driver IC

■ Overview

The MN31121SA is a 2D interline CCD image sensor vertical driver IC that integrates four vertical driver channels and one SUB drive channel on a single chip. This IC can reduce power consumption and the number of external parts.

The MN31121SA consists of a vertical driver block that includes both level shifter circuits and 2-value and 3-value output driver circuits, and a SUB driver block that includes level shifter and 2-value output driver circuits.
