the FCCD 143D is a linear CCD, which is a light sensor that contains an array of photosensitive elements fixed end to end in a single line. Images are drawn by scanning a beam of light across the length of the CCD, capturing one line at a time. In this device, the light sensitive die has been packaged in a large 28 pin ceramic DIP with a glass cavity lid. The die for this device is much larger than what would be used in a conventional integrated circuit, and spans nearly the entire length of the device.
