† _{Stresses beyond 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 beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 2. Minimum dc voltage on input or I/O pins is –0.5V. During voltage transitions, input or I/O pins may undershoot VSS to –2.0 V for
periods of up to 20 ns. Maximum dc voltage on input and I/O pins is VCC + 0.5V. During voltage transitions, input and I/O pins may
overshoot to VCC + 2.0 V for periods up to 20 ns.
3. Minimum dc input voltage on A9, E, and G pins is –0.5 V. During voltage transitions, A9, E, and G may undershoot VSS to –2.0 V
for periods of up to 20 ns. Maximum dc input voltage on A9, E, and G pins is +12.5 V, which may overshoot to +13.5 V for periods
up to 20 ns.
