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. See FIG: 11. Maximum DC voltage
on input or I/Os is VCC + 0.5 V. During voltage transitions inputs or I/Os may overshoot to VCC + 2.0 V for periods up to 20 ns. See FIG: 12.
2.
Minimum DC input voltage on pins A9 and ACC is -0.5V. During voltage transitions, A9 and ACC may overshoot VSS to –2.0 V for periods of up to 20 ns. See FIG: 11. Maximum DC
voltage on pins A9 and ACC is +12.5 V, which may overshoot to 14.0 V for periods up to 20 ns.
3.
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.
4.
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.
