The μ PD3747 is a high-speed and high sensitive CCD (Charge Coupled Device) linear image sensor which changes optical images to electrical signal.

The μ PD3747 is a 2-output type CCD sensor with 2 rows of high-speed charge transfer register, which transfers the photo signal electrons of 7400 pixels separately in odd and even pixels. And it has reset feed-through level clamp circuits and voltage amplifiers. Therefore, it is suitable for 600 dpi/A3 high-speed digital copiers, multi-function products and so on.
