Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: All currents into device pins are positive; all currents out of device
pins are negative. All voltages are referenced to ground unless otherwise
specified.
Note 3: An internal Zener on the GATE pins clamp the charge pump
voltage to a typical maximum operating voltage of 28V. External overdrive
of the GATE pin beyond the internal Zener voltage may damage the device.
