AC Electrical Characteristics (Continued)

The following specifications apply for V

CC =+3 VDC, and tr =t f = 20 ns unless otherwise specified. Boldface limits apply for

A =TJ =T MIN to TMAX; all other limits TA =TJ = 25˚C.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.

Note 2: Operating Ratings indicate conditions for which the device is functional. These ratings do not guarantee specific performance limits. For guaranteed speci-

fications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance character-

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

Note 3: All voltages are measured with respect to GND = 0 VDC, unless otherwise specified.

Note 4: When the input voltage VIN at any pin exceeds the power supplies (VIN <GND or VIN > VCC) the current at that pin should be limited to 5 mA. The 20 mA

maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 5 mA to four pins.

Note 5: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA and the ambient temperature, T A. The maximum

allowable power dissipation at any temperature is P D =(TJMAX −TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower.

Note 6: Human body model, 100 pF capacitor discharged through a 1.5 k

Ω resistor.

Note 7: See AN450 “Surface Mounting Methods and Their Effect on Product Reliability” or Linear Data Book section “Surface Mount” for other methods of soldering

surface mount devices.

Note 8: Typicals are at TJ = 25˚C and represent the most likely parametric norm.

Note 9: Guaranteed to National’s AOQL (Average Outgoing Quality Level).
