Notes:

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

voltage transitions, inputs may undershoot VSS to –2.0 V

for periods of up to 20 ns. See Figure 5. 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 + 2.0 V for periods up to 20 ns. See Figure 6.

2. Minimum DC input voltage on A9 pin is –0.5 V. During

voltage transitions, A9 and OE# may undershoot VSS to

–2.0 V for periods of up to 20 ns. See Figure 5. Maximum

DC input voltage on A9 and OE# is 12.5 V which may

overshoot to 13.5 V for periods up to 20 ns.

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

Duration 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 op-

erational sections of this specification is not implied. Expo-

sure of the device to absolute maximum rating conditions for

extended periods may affect device reliability.
