Notes:
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 VDD +0.5 V. During voltage transitions, input or
I/O pins may overshoot to VDD +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
+11.5 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.
