DETERMINING ACTIVE CURRENT CONSUMPTION AND POWER DISSIPATION

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.

CALCULATING POWER DISSIPATION

N

where:

N

= number of used outputs (36-bit (long word), 18-bit (word) or 9-bit (byte) bus size)

= switching frequency of an output
