detailed description
The TC245 consists of four basic functional blocks: (1) the image-sensing area, (2) the image-storage area,
(3) the multiplexer block with serial registers and transfer gates, and (4) the low-noise signal-processing
amplifier block with charge-detection nodes. The location of each of these blocks is identified in the functional
block diagram.
