NOTES:
1. Minimum DC voltage on input or I/O pins is –0.5 V. During voltage transitions, inputs may
overshoot V
SS
to –2.0 V for periods of up to 20 ns. See . Maximum DC voltage on output and
I/O pins is V
CC
+ 0.5 V. During voltage transitions, outputs may overshoot to V
CC
+ 2.0 V for
periods up to 20 ns. See .
2. Minimum DC input voltage on A9, OE#, RESET# pins is –0.5V. During voltage transitions, A9,
OE#, RESET# pins may overshoot V
SS
to –2.0 V for periods of up to 20 ns. See 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.
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 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.
This parameter is guaranteed by design but not tested.
