DETERMINING ACTIVE CURRENT CONSUMPTION AND POWER DISSIPATION
CLKA and CLKB set to f
disconnected 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.
