AC Electrical Characteristics
Note 1 Output matching is calculated as the percent variation from I
Note 2 With a fixed resistor on the brightness input pin some variation in brightness will occur from one device to another Maximum brightness input current can
be 2 mA as long as Note 3 and junction temperature equation are compiled with
Note 3 Absolute maximum for each output should be limited to 40 mA
