UPD3734ACY

The UPD3734ACY is one member of the UPD3734A series.The UPD3734A is a high sensitivity CCD (Charge Coupled Device) linear image sensor which changes optical images to electrical signal.The UPD3734A has 2660 pixels and an output amplifier which has high gain and wide output range, but low noise.Built-in sample and hold circuit converts and outputs independent signal from CCD register in every pixel to continuous video signal.  So it is easy to interface to A/D converter or Bi-level converter.

Features of the UPD3734ACY are:(1)valid photocell : 2660 pixels; (2)photocell's pitch : 11 m; (3)high sensitivity : 70 V/lx`s TYP.; (4)peak response wavelength : 550 nm (green); (5)resolution:12 dot/mm A4 (210 * 297 mm) size (shorter side) 300 dpi US letter (8.5" * 11") size (shorter side); (6)power supply : +12 V; (7)drive clock level : cmos output under 5 V operation; (8)high speed scan:0.54 ms/line (S/H in used); (9)built-in circuit:sample and hold circuit,reset feed-through level clamp circuit,clamp pulse generation circuit,voltage amplifier; (10)low noise:a quarter of the UPD3734; (11)low image lag:1 % MAX.; (12)pin assign:compatible with the UPD3734. 

The absolute maximum ratings of the UPD3734ACY can be summarized as:(1)operating ambient temperature:-25 to 60;(2)storage temperature:-40 to 70;(3)output drain voltage:-0.3V to +15V;(4)shift register clock voltage:0.3 to +15V;(5)reset gate clock voltage:0.3 to +15 V;(6)transfer gate clock voltage:-0.3V to 15V;(7)sample and hold clock voltage:-0.3 to 15V.NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property rights of third parties by or arising from use of a device described herein or any other liability arising from use of such device.No license, either express, implied or otherwise, is granted under any patents,copyrights or other intellectual property rights of NEC Corporation or others.While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices,the possibility of defects cannot be eliminated entirely.  To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customer must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features.
