Absolute Maximum Ratings[2]
Stresses greater than those listed in this table may cause
permanent damage to the device. These represent a stress
rating only. Operation of the device at these or any other condi-
tions above those specified in the operating sections of this
specification is not implied. Maximum conditions for extended
periods may affect reliability.

Note:
2. Multiple Supplies: The Voltage on any input or I/O pin cannot exceed the power pin during power-up. Power supply sequencing is NOT required.
3. All AC tests are performed using the circuit shown in Figure 1 to simulate typical system load conditions. Measurements are taken at the load. Threshold voltage
for timing measurements is 1.5V.
