1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.

1. This parameter is determined by device characterization but is not
production tested.
2. 3dv references the interpolated capacitance when the input and output
signals switch from 0V to 3V or from 3V to 0V.
