Absolute Maximum Ratings*

Storage Temperature........................ -30°C to +70°C

Ambient Temperature with

Power Applied................................... -10°C to +70°C

Voltage with

Respect to Ground, All pins (1)........... -2.0V to +7.0V

VCC (1) ................................................ -2.0V to +7.0V

Output Short Circuit Current (2) .................... -200 mA

*NOTICE: Stresses beyond those listed under "Absolute Maxi-

mum Ratings" may cause permanent damage to the card.

This is a stress rating only and functional operation of the

card at these or any other conditions beyond those indi-

cated in the operational sections of this specification is not

implied.Exposure to absolute maximum rating conditions for

extended periods may affect device reliability.

Notes:

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

voltage transients, inputs may overshoot VSS to -2.0V for

periods of up to 20 ns. Maximum DC voltage on output and

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

may overshoot to VCC + 2.0V for periods up to 20 ns.

2. No more than one output shorted at a time. Duration of the

short circuit should not be greater than one second. Condi-

tions equal VOUT = 0.5V or 5.0V, VCC = Max.
