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.

2. Ambient Temperature Under DC Bias. No AC Conditions. Chip Deselected.

NOTES:

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.
