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 4: Human body model, 100 pF discharged through a 1.5 k
Note 5: Typical specifications are specified at +25˚C and represent the most likely parametric norm.
Note 6: Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).
Note 7: The supply current specified is the quiescent current for V

Note 8: Output voltage is dependent on load resistor. Test circuit uses R
Note 9: Measure gain difference between any two amplifiers. V

max the three amplifiers’ gains might be 17.1 dB, 16.9 dB and 16.8 dB and change to 11.2 dB, 10.9 dB, and 10.7 dB respectively for V12 = 2V. This yields the mea-
sured typical
Note 11: When measuring video amplifier bandwidth or pulse rise and fall times, a double sided full ground plane printed circuit board without socket is recom-
mended. Video amplifier 10 MHz isolation test also requires this printed circuit board. The reason for a double sided full ground plane PCB is that large measurement
variations occur in single sided PCBs.
Note 12: Adjust input frequency from 10 MHz (A
Note 13: Measure output levels of the other two undriven amplifiers relative to the driven amplifier to determine channel separation. Terminate the undriven amplifier
inputs to simulate generator loading. Repeat test at f
Note 14: During the AC tests the 4V DC level is the center voltage of the AC output signal. For example, if the output is 4 V
and 6V DC.
Note 15: Machine Model ESD test is covered by specification EIAJ IC-121-1981. A 200 pF 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 ).
See AC Test Circuit ( Figure 3 ) , T
for the AC test unless otherwise stated.
