DATA SHEET

MOS INTEGRATED CIRCUIT

µ PD3777

5400 PIXELS × 3 COLOR CCD LINEAR IMAGE SENSOR

The µ PD3777 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 µ PD3777 has 3 rows of 5400 pixels, and each row has a double-sided readout type of charge transfer register. And

it has reset feed-through level clamp circuits, a clamp pulse generation circuit and voltage amplifiers. Therefore, it is

suitable for 600 dpi/A4 color image scanners, color facsimiles and so on.
