calculating power dissipation

The maximum power dissipation (PT) of the SN74ACT7811 can be calculated by:

PT = VCC × [ICC + (N × ∆ICC × dc)] + Σ (Cpd × VCC2 × fi) + Σ (CL × VCC2 × fo)

where:

ICC

power-down ICC maximum

number of inputs driven by a TTL device

∆ ICC = increase in supply current

duty cycle of inputs at a TTL high level of 3.4 V

Cpd

power dissipation capacitance

output capacitive load

data input frequency

data output frequency
