TCD1707D

The TCD1707D is designed as a high sensitive and low dark current 7450 elements CCD image sensor for facsimile, imagescanner and OCR.

TCD1707D has five features. (1)Number of image sensing elements 7450 elements. (2)Image sensing element size 4.7um by 4.7um on 4.7um centers. (3)Photo sensing region is high sensitive and low voltage dark signal pn photodiode. (4)Clock is 2 phase (5V). (5)Package is 22 pin CERDIP. Those are all the main features.

Some absolute maximum ratings of TCD1707D have been concluded into several points as follow. (1)Its colck pulse voltage would be from -0.3V to 8V. (2)Its shift pulse voltage would be from -0.3V to 8V. (3)Its reset pulse voltage would be from -0.3V to 8V. (4)Its clamp pulse voltage would be from -0.3v to 8V. (5)Its power supply voltage would be from -0.3V to 15V. (6)Its operating temperature range would be from 0°C to 60°C. (7)Its storage temperature range would be from -25°C to 85°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.
