Notes:

1. Minimum DC voltage on input or I/O pins is –0.5 V. During

voltage transitions, inputs may overshoot VSS to –2.0 V for

periods of up to 20 ns. Maximum DC voltage on input and

I/O pins is VCC + 0.5 V. During voltage transitions, input

and I/O pins may overshoot to VCC + 2.0V for periods up

to 20 ns.

2. Minimum DC input voltage on A9 and VPP pins is –0.5 V.

During voltage transitions, A9 and VPP may overshoot

VSS to –2.0 V for periods of up to 20 ns. Maximum DC

input voltage on A9 and VPP is +13.0 V which may

overshoot to 14.0 V for periods up to 20 ns.

3. No more than one output shorted to ground at a time. Du-

ration of the short circuit should not be greater than one

second.

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 opera-

tional sections of this specification is not implied. Exposure of

the device to absolute maximum rating conditions for extended

periods may affect device reliability.
