NOTES:
1.
Minimum DC voltage on input or input or I/Os is -0.5V. During voltage transitions,
inputs or I/Os may overshoot V
SS
to -2.0V for periods of up to 20ns. Maximum DC
voltage on input or I/Os us VCC + 0.5V. During voltage transitions, input or I/O pins
may overshoot to V
CC
+ 2.0V for periods up to 20ns
2.
Minimum DC input voltage on pins A9, OE#, and ACC is 0.5V. During voltage
transitions, A9, OE#, and ACC may overshoot V
SS
to -2.0V for periods of up to 20ns.
Maximum DC input voltage on pin A9, OE#, and ACC is +12.5V which may overshoot
to +14.0V for periods up to 20ns
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 Maxium 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 the data sheet is not implied. Exposure of the device to absolute maxium rating
conditons for extended peroids may affect device reliability
