Voltage with Respect to Ground

All pins except A9 and VPP (Note 1) .–2.0 V to +7.0 V

VCC (Note 1). . . . . . . . . . . . . . . . . . . .–2.0 V to +7.0 V

A9, VPP (Note 2) . . . . . . . . . . . . . . . –2.0 V to +14.0 V

Output Short Circuit Current (Note 3) . . . . . . 200 mA

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 VSS to

–2.0 V for periods of up to 20 ns. Maximum DC voltage on

input or I/O pins is VCC +0.5 V. During voltage transitions,

input or I/O pins may overshoot to VCC +2.0 V for periods

up to 20 ns.

2. Minimum DC input voltage on pins A9 and VPP is –0.5 V.

During voltage transitions, A9 and VPP may overshoot

VSS to –2.0 V for periods of up to 20 ns. Maximum DC

input voltage on pin A9 and VPP is +13.0 V, which may

overshoot to 14.0 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.

4. 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.
