1. Minimum DC voltage on input or I/O pins is -0.5 V. During voltage transitions, input or I/O pins may overshoot V SS to
-
2.0 V for periods of up to 20 ns. Maximum DC voltage on input or I/O pins is V DD +0.5 V. During voltage transitions,
input or I/O pins may overshoot to V DD +2.0 V for periods up to 20 ns.
2. Minimum DC input voltage on pins A9, #OE, #RESET, and #WP/ACC is -0.5 V. During voltage transitions, A9, #OE,
#WP/ACC, and #RESET may overshoot V SS to -2.0 V for periods of up to 20 ns. Maximum DC input voltage on pin A9 is
+12.5 V which may overshoot to +14.0 V for periods up to 20 ns. Maximum DC input voltage on #WP/ACC is +9.5 V
which may overshoot to +12.0 V for periods up to 20 ns.
3. No more than one output may be 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 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.
