TCD1704C

The TCD1704C is designed as a high sensitive and low dark current 7500 elements CCD image sensor which is for facsimile, imagescanner and OCR.

TCD1704C has five features. (1)Number of image sensing elements is 7500 elements. (2)Image sensing element size is 7um by 7um on 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 24 pin DIP. Those are all the main features.

Some absolute maximum ratings of TCD1704C have been concluded into several points as follow. (1)Its clock 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.

Also some electrical characteristics of TCD1704C are concluded as follow. (1)Its sensitivity would be min 13.6V and typ 17V and max 20.4V. (2)Its photo response non uniformity would be typ 3% and max 10%. (3)Its saturation output voltage would be min 1.5V and typ 2.5V. (4)Its saturation exposure would be min 0.07lxs and typ 0.14lxs. (5)Its dark signal voltage would be typ 1.0mV and max 3mV. (6)Its dark signal non uniformity would be typ 2.0mV and max 4mV. (7)Its DC power dissipation would be typ 800mW and max 1200mW. (8)Its total transfer efficiency would be min 92% and typ 98%. (9)Its output impedance would be typ 0.2kohms and max 1kohms. And so on.
