Voltage with Respect To VSS
All pins except A9,VPP,VCC . –0.6 V to VCC + 0.5 V
A9 and VPP . . . . . . . . . . . . . . . . –0.6 V to +13.5 V
VCC . . . . . . . . . . . . . . . . . . . . . . . –0.6 V to +7.0 V
Notes:
1. Minimum DC voltage on input or I/O pins is –0.5 V. During
transitions, the inputs may overshoot VSS to –2.0 V for pe-
riods of up to 20 ns. Maximum DC voltage on input and I/O
pins is VCC + 0.5 V which may overshoot to VCC + 2.0 V for
periods up to 20 ns.
2. For A9 and VPP the minimum DC input is –0.5 V. During
transitions, A9 and VPP may overshoot VSS to –2.0 V for
periods of up to 20 ns. A9 and VPP must not exceed 13.5 V
for any period of time.
Stresses above those listed under “Absolute Maximum Rat-
ings” 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 opera-
tional sections of this specification is not implied. Exposure of
the device to absolute maximum rating conditions for ex-
tended periods may affect device reliability.
