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.

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.

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 (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.
