NOTE:
1. This parameter is guaranteed by device characterization, but not production tested.
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
DD
termnals only.
3. V
DDQ
termnals only.
4. Input termnals only.
5. I/O termnals only.
6. This is a steady-state DC parameter that applies after the power supply has
reached its nomnal 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.
7. T
