MOS INTEGRATED CIRCUIT
µPD3739
5000 PIXELS CCD LINEAR IMAGE SENSOR
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.

Note Input the reset gate clocks 1 and 2 (φR1, φR2) to pins 5 and 18, respectively, via an input resistor and a capacitor.
Use of a capacitor is indispensable. Refer to APPLICATION CIRCUIT EXAMPLE for the connection method.
The reset gate clock high level and low level at the IC pins (after passing through the external capacitor) varies
according to the IC, due to the on-chip automatic φR level adjuster. The recommended operating conditions
of reset gate clocks 1, 2 (φR1, φR2) in the table above are for signals applied to the external capacitor.
Remark φ1 in the above tables represents φ11, φ12 and φ1L2. φ2 represents φ21, φ22 and φ2L1.
