≤ 100 mV

Voltage on Any Input or Output Pin

±25 mA

±50 mA

ESD Susceptibility

2500V

250V

Storage Temperature

Soldering process must comply with National Semiconductor's Reflow Temperature Profile specifications. Refer to

www.national.com/packaging.(6)

(1)

All voltages are measured with respect to GND = AGND = DGND = 0V, unless otherwise specified.

(2)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see

the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics

may degrade when the device is not operated under the listed test conditions.

(3)

limited to 25 mA. The 50 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies

with an input current of 25 mA to two.

(4)

a severe fault condition (e.g. when input or output pins are driven beyond the power supply voltages, or the power supply polarity is

reversed). Obviously, such conditions should always be avoided.

(5)

Human body model is 100 pF capacitor discharged through a 1.5 k

Ω resistor. Machine model is 220 pF discharged through 0Ω.

(6)

Reflow temperature profiles are different for lead-free and non-lead-free packages.
