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 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 de-

grade when the device is not operated under the listed test conditions.

Note 3: Typical specifications are specified at +25˚C and represent the most likely parametric norm.

Note 4: Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).

bient temperature.

Note 6: When measuring video amplifier bandwidth or pulse rise and fall times, a double sided full ground plane printed circuit board is recommended. The measured

rise and fall times are effective rise and fall times, taking into account the rise and fall times of the generator and the oscilloscope.
