Notes:
1.
Minimum DC voltage on input or I/O pins is –0.5 V. During voltage transitions, inputs may undershoot
VSS to –1.0V for periods of up to 50 ns and to –2.0 V for periods of up to 20 ns. See Left Figure below.
Maximum DC voltage on input and I/O pins is V CC + 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 Right Figure below.
2.
Minimum DC input voltage on A9 pin is –0.5 V. During voltage transitions, A9 and OE# may
undershoot VSS to –1.0V for periods of up to 50 ns and to –2.0 V for periods of up to 20 ns. See Left
Figure. Maximum DC input voltage on A9 and OE# is 11.5 V which may overshoot to 12.5 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 operational sections of this specification is
not implied. Exposure of the device to absolute maximum rating conditions for extended periods may
affect device reliability.
