Notes:
1. Minimum DC voltage on input or I/Os is –0.5 V. During voltage transitions, inputs
or I/Os may undershoot V
SS
to –2.0 V for periods of up to 20 ns. See Figure 9.
Maximum DC voltage on input or I/Os is V
CC
+ 0.5 V. During voltage transitions
outputs may overshoot to V
CC
+ 2.0 V for periods up to 20 ns. See Figure 10.
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
permanent 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 maximum rating conditions for extended periods may affect device
reliability.
