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

Notes:

1. Minimum DC voltage on input or I/O pins is –0.5 V.

During vo lta ge transitions , in put or I/O pin s may

overshoot V

SS to – 2.0 V for pe riods of up to 20 ns.

Maximum DC voltage on input or I/O pins is V

CC +0.5 V.

See Figure 7. During voltage transitions, input or I/O pins

may overshoot to V

CC +2.0 V for periods up to 20 ns. See

Figure 8.

2. Minimum DC input voltage on pins OE#, RESET#, and

WP#/ACC is –0.5 V. During voltage transitions, OE#,

WP#/ACC, and RESET# may overshoot V

SS to –2.0 V

for periods of up to 20 ns. See Figure 7. Maximum DC

input voltage on pin RESET# 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.

Expo sure o f the device to absolute maximum rating

conditions for extended periods may affect device reliability
