... MIC5400 General Description The MIC5400 consists of 2 banks of 8 LED driver outputs, each output capable of sinking up to 30mA. Each bank is intended to drive 8 LED pixels of the same color. Most applications will use the MIC5400 to drive pixel clusters of 4 LEDs (RRGB.) Typically two red LEDs are used for every one green and blue to compensate for red LED brightness ...

... LOAD and the Data/Control and Status Registers: When LOAD is low, the MIC5400 acts as a 36-bit shift register. When LOAD goes high, the part no longer shifts data. Data is transferred from the Shift Register to the parallel control registers on the first falling edge of SHIFTCLK after LOAD goes high ...
