MOS INTEGRATED CIRCUIT

The

µPD3739 is a CCD (Charge Coupled Device) linear image sensor which changes optical images to electrical

signal.

The

µPD3739 is a 2-output type CCD sensor with 2 rows of high-speed charge transfer register, which transfers

the photo signal electrons of 5000 pixels separately in odd and even pixels. It is developed as the higher sensitivity

version of the previous device, the

µPD35H71A. It is suitable for 400 dpi/A3 high-speed digital copiers, OCRs and

high-end business facsimiles.
