Oncethecapacitanceloadperdata-outputchannelandthenumberofIDT723623/723633/723643inputs driven by TTL HIGH levels are known, the power dissipation can be calculated with the equation below. CALCULATING POWER DISSIPATION With ICC(f) taken from Figure 1, the maximum power dissipation (PT) of these FIFOs may be calculated by: PT = VCC x [ICC(f) + (N x ΔICC x dc)] + Σ(CL x VCC2 X fo) where: N = number of used outputs = 36-bit (long word), 18-bit (word) or 9-bit (byte) bus size ΔICC = increase in power supply current for each input at a TTL HIGH level dc = duty cycle of inputs at a TTL HIGH level of 3.4 V CL = outputcapacitanceload fo = switchingfrequencyofanoutput Figure 1.
