What is the maximum drive current that the Si8661 can source per output channel without affecting performance of the other channels? Is there a total drive current specification for all of side B (e.g., sum of all 5 output channels)? Want to drive a 1 Kohm pull-down resistor on Side B with VDD2 at 5V. Have yet to test with any other channels active, and not sure if there is a maximum per channel or a maximum for all outputs (total).
The current maximum is per-channel (10mA).
Also, channel drive strengths are independent so long as you are under the thermal limit of the package (when summing all power being passed through the part).
