Electrical Characteristics
Note 1 Output matching is calculated as the percent variation (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 complied with
Note 3 See Figures 5 6 and 7 for Recommended Operating Conditions and limits Absolute maximum for each output should be limited to 40 mA
Note 4 The V
Note 5 AC input waveform specification for test purpose t
Note 6 Clock input rise and fall times must not exceed 300 ns
