The PD16520 is a vertical driver for CCD image sensors that has a level conversion circuit and a 3-level output function. Since it incorporates a CCD vertical register driver equivalent to the PD16510 (10 channels, consisting of six 3-level channels and four 2-level channels) and a VOD shutter driver (1 channel), it is ideal as a vertical driver for multiple-electrode high-pixel CCD transfer type area image sensors employed in digital still cameras. The PD16520 uses a CMOS process to achieve optimum transmission delay characteristics for vertical driving of CCD image sensors, as well as output on-state resistance characteristics. The PD16520 also supports low-voltage logic (logic supply voltage: 2.0 to 5.5 V).
