Note 1

Output matching is calculated as the percent variation (IMAX aIMIN)2

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

Absolute maximum for each output should be limited to 40 mA

Note 4

The VOUT voltage should be regulated by the user See Figures 6 and 7 for allowable VOUT vs IOUT operation

Note 6

Clock input rise and fall times must not exceed 300 ns
