1 / 24 page MOS INTEGRATED CIRCUIT µPD3739 The µPD3739 is a CCD (Charge Coupled Device) linear image sensor which changes optical images to electrical signal. The µPD3739 is a 2-output type CCD sensor with 2 rows of high-speed charge transfer register, which transfers the photo signal electrons of 5000 pixels separately in odd and even pixels. It is developed as the higher sensitivity version of the previous device, the µPD35H71A. It is suitable for 400 dpi/A3 high-speed digital copiers, OCRs and high-end business facsimiles. FEATURES • Valid photocell : 5000 pixels • Photocell’s pitch : 7 µm • High sensitivity : 9.0 V/lx·s TYP. (Light source: Daylight color fluorescent lamp) • Low image lag : 1 % MAX. • Peak response wavelength : 550 nm (green) • Resolution : 16 dot/mm (400 dpi) A3 (297 × 420 mm) size (shorter side) • Data rate : 40 MHz MAX. (20 MHz/1 output) • Output type : 2 outputs out of phase (2 outputs in phase also supported) • Power supply : +12 V • Drive clock level : CMOS output under 5 V operation • On-chip circuit : Automatic φR level adjuster • Pin assign : Functional compatible with the µPD35H71A ORDERING INFORMATION Part Number Package µPD3739D CCD linear image sensor 22-pin ceramic DIP (CERDIP) (400 mil) Document No. S12744EJ1V0DS00 (1st edition) Date Published September 1997 N Printed in Japan 5000 PIXELS CCD LINEAR IMAGE SENSOR The information in this document is subject to change without notice. © 1997 DATA SHEET |
