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.

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.
3. C OUT also references C I/O .
