Notes:
1. Minimum DC voltage on input or I/O pins is –0.5 V. During 
voltage transitions, inputs may undershoot V
SS
 to –2.0 V 
for periods of up to 20 ns. See Figure

. 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 
V
CC
 + 2.0 V for periods up to 20  ns. See Figure

.
2. Minimum DC input voltage on A9 pin is –0.5 V. During 
voltage transitions, A9 and OE# may undershoot V
SS
 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.
