Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any parameter. That is, the absolute maximum ratings are rated values at which the product is on the verge of suffering physical damage, and therefore the product must be used under conditions that ensure that the absolute maximum ratings are not exceeded.




Description

The PD8891 is a color CCD (Charge Coupled Device) linear image sensor which changes optical images to electrical signal and has the function of color separation.

The PD8891 has 3 rows of (5340+5340) staggered pixels, and each row has a dual-sided readout type of charge transfer register, and has 3 rows of 2670 pixels, and each row has a single-sided readout type of charge transfer register. And it has reset feed-through level clamp circuits and voltage amplifiers. Therefore, it is suitable for 1200 dpi/A4 color image scanners, color facsimiles and so on.
