∗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.
