1.
Minimum DC voltage on any Input or Input/Output pin is
–0.5v. During voltage transitions, input or input/output
pins may undershoot VSS to –2.0v for periods of up to
20ns.
Test Set-Up
3.3v
2.
Minimum DC input/output voltage on pins A9, OE\, and
RESET\ is-0.5v. During voltage transitions, A9, OE\, and
RESET\ may undershoot VSS to –2.0v for periods of up to
20ns. Maximum DC input voltage on pin A9 is +12.5v
which may overshoot to 14.0v for periods up to 20ns.
No more than one output may be shorted to ground at a
time. Duration of the short circuit should not be greater
than one (1) second.

*Stress greater than those listed under ABSOLUTE
MAXIMUM RATINGS may cause permanent damage to
the device. This is a stress rating only and functional
operation of the device at these or any other conditions
greater than those indicated in the operational sections of
this specification is not implied. Exposure to absolute
maximum conditions for any duration or segment of time
may affect device reliability.
