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. See Figure 6. Maximum DC

voltage on output and I/O pins is VCC + 0.5 V. During

voltage transitions, outputs may overshoot to VCC + 2.0 V

for periods up to 20 ns. See Figure 7.

2. Minimum DC input voltage on A9, OE#, RESET# pins is

–0.5V. During voltage transitions, A9, OE#, RESET# pins

may overshoot VSS to –2.0 V for periods of up to 20 ns.

See Figure 6. Maximum DC input voltage on A9, OE#,

and RESET# is 12.5 V which may overshoot to 13.5 V for

periods up to 20 ns.

3. No more than one output shorted at a time. Duration of

the short circuit should not be greater than one second.

Stresses greater than those listed in this section may cause

permanent damage to the device. This is a stress rating only;

functional operation of the device at these or any other condi-

tions above those indicated in the operational sections of this

specification is not implied. Exposure of the device to absolute

maximum rating conditions for extended periods may affect

device reliability.
