Notes:
1. Minimum DC voltage on input or I/O pins is –0.5 V. During voltage transitions, input or I/O pins may undershoot V to
SS
-2.0V for periods of up to 20 ns. See Figure 9. Maximum DC voltage on input or I/O pins is VCC + 0.5 V. During voltage
transitions, input or I/O pins may overshoot to VCC +2.0 V for periods up to 20 ns. See Figure 10.
2. Minimum DC input voltage on pins A[9], OE#, and RESET# is -0.5 V. During voltage transitions, A[9], OE#, and RESET#
may undershoot VSS to –2.0 V for periods of up to 20 ns. See Figure 9. Maximum DC input voltage on these pins is +12.5
V which may overshoot to 13.5 V for periods up to 20 ns.
3. No more than one output at a time may be shorted to VSS. Duration of the short circuit should be less than one second.
4. 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 data sheet is not implied. Exposure of the device to absolute maximum rating conditions for
extended periods may affect device reliability.
