NOTES:
1. Minimum DC voltage is -0.5V on input/output pins. During transitions, this level
may undershoot to -2.0V for periods <20ns. Maximum DC voltage on input/output
pins is VCC + 0.5V which, during transitions, may overshoot to VCC + 2.0V for
periods <20ns.
2. Minimum DC input voltage on pins A9, OE#, and RESET is -0.5V. During voltage
transitions, A9, OE#, and RESET may undershoot Vss to -2.0V for periods of up
to 20ns. See Figure 6. Maximum DC input voltage on pin A9 is +12.5V which may
overshoot to +13.5V for periods up to 20ns.

3. Output shorted for no more than one second. No more than one output shorted
at a time.
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent
damage to the device. This is a Stress rating only and 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 to absolute maximum rating conditions for
extended periods may affect device reliability.
