Note 1

CV channels defined with a CV mute condition set up (ABC e 001) and all CV inputs driven Isolation is the output measured with respect to the input level

for RL of 600X Channel isolation for RGB channels is measured in the same way with signals applied to the R G or B inputs while a RGB mute condition is

selected

Note 2

CV crosstalk measured with selected channel input AC grounded and with signal applied to the other CV inputs Resulting output voltage is measured with

RL of 600X RGB crosstalk is measured similarly with signals applied to unselected channel inputs and measuring the selected channel output Note that high

frequency crosstalk measurements are very dependent on board layout An effective ground plane and input to input shielding are required

Note 3

DC output current sourced from device to load should not exceed 10 mA care should be taken to avoid shorting outputs to GND

Note 4

Delay between clamp pulse input at Pin 18 and resulting clamping action as seen at RGB inputs

Note 5

Human body model 100 pF discharged through a 15 kX resistor

Note 6

Guaranteed and 100% production tested

Note 7

Design limits are guaranteed to National’s AOQL but are not 100% production tested

Note 8

When operating at elevated temperatures the maximum power dissipation must be derated based on a maximum junction temperature of 150 C and
