Note)

1) The MOS structure of this IC has a low tolerance for static electricity, so full care should be given for

measures to prevent electrostatic discharge.

2) For noise and latch-up countermeasures, be sure to connect a by-pass capacitor (0.1µF or more)

between each power supply pin (VH, VL) and GND.

3) To protect the CCD image sensor, clamp the SUB pin output at VH before input to the CCD image

sensor.
