Voltage with Respect to Ground:

All Inputs and I/Os except as noted below (Note 1) . . . . –0.5 V to VIO + 0.5 V

ACC. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . –0.5 V to +12.5 V

Output Short Circuit Current (Note 3)100 mA

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.
