Notes:
1. Minimum DC voltage on input or I/Os is –0.5 V. During voltage transitions, inputs
or I/Os may undershoot VSS to –2.0 V for periods of up to 20 ns during voltage
transitions inputs might overshoot to VCC +0.5 V for periods up to 20 ns. See
Figure 6. Maximum DC voltage on input or I/Os is VCC + 0.5 V. During voltage
transitions outputs may overshoot to VCC + 2.0 V for periods up to 20 ns. See
Figure 7.
2. No more than one output may be shorted to ground at a time. Duration of the
short circuit should not be greater than one second.
3. Stresses above those listed under “Absolute Maximum Ratings” may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
sections of this data sheet is not implied. Exposure of the device to absolute max-
imum rating conditions for extended periods may affect device reliability.
