DETERMINING ACTIVE CURRENT CONSUMPTION AND POWER DISSIPATION
and CLKB set to f
to normalize the graph to a zero capacitance load. Once the capacitance load per data-output channel and the number of these device's inputs driven by TTL
HIGH levels are known, the power dissipation can be calculated with the equation below.
