1. These parameters are determined 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 from 3V to 0V.

NOTES:
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. This is a steady-state DC parameter that applies after the power supply has
reached its nominal operating value. Power sequencing is not necessary;
however, the voltage on any Input or I/O pin cannot exceed V
DDQ
during power
supply ramp up.
3. Ambient Temperature under DC Bias. No AC Conditions. Chip Deselected.
