(1)

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.

(2)

Human body model, 100pF discharged through a 1.5k

Ω resistor.

(3)

Machine Model ESD test is covered by specification EIAJ IC-121-1981. A 200pF cap is charged to the specified voltage, then

discharged directly into the IC with no external series resistor (resistance of discharge path must be under 50

Ω).
