NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUMRATINGS 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
maximumrating conditions for extended periods may affect reliability.
2. V

NOTES:
1. These parameters are determned by device characterization, but are not
production tested.
2. 3dV references the interpolated capacitance when the input and output switch from
0V to 3V or from3V to 0V.
