Current(4)

(4)

IDR is the current consumed by the switching of the output drivers and is primarily determined by the load capacitance on the output

pins, the supply voltage, VDR, and the rate at which the outputs are switching (which is signal dependent). IDR = VDR (CO x fO + C1 x f1

+ ... + C9 x f9) where VDR is the output driver power supply voltage, Cn is the total capacitance on the output pin, and fn is the average

frequency at which that pin is toggling.
