Note 1: See AN-450 "Surface Mounting and their effects on Product Reliability" for other methods of soldering surface mount devices.
Note 2: 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.
Note 3: Human body model, 100pF discharged through a 1.5kΩ resistor.
Note 4: Typical specifications are specified at +25°C and represent the most likely parametric norm.
Note 5: Tested limits are guaranteed to National's AOQL (Average Outgoing Quality Level).
Note 6: 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 50Ω).
Note 7: All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 8: The given θ
for an LM4947TL mounted on a demonstration board with a 9in
2
area of 1oz printed circuit board copper ground plane.
