Notes:
1. Output matching is calculated as the percent variation (I
2. With a fixed resistor on the brightness input pin, some variation in brightness will occur among devices.
3. See Figures 7, 8 and 9 for recommended operating conditions and limits. Absolute maximum for each output should be limited to 40mA.
4. V
5. AC input waveform specification for test purpose: t
6. Clock input rise and fall times must not exceed 300ns.
