Stresses above those listed under “Absolute Maximum

Ratings” may cause permanent damage to the device.

These are stress ratings only, and functional operation

of the device at these or any other conditions outside of

those listed in the operational sections of this specifica-

tion is not implied. Exposure to any absolute maximum

rating for extended periods may affect device perfor-

mance and reliability.

Note:

(1) The minimum DC input voltage is –0.5V. During transitions, inputs may undershoot to –2.0V for periods of less than 20 ns. Maximum DC

voltage on output pins is VCC +0.5V, which may overshoot to VCC +2.0V for periods of less than 20 ns.

(2) Output shorted for no more than one second. No more than one output shorted at a time.

(3) This parameter is tested initially and after a design or process change that affects the parameter.

(4) Latch-up protection is provided for stresses up to 100 mA on address and data pins from –1V to VCC +1V.
