Note: 1. This is the increase in supply current for each input that is at one of the specified TTL voltage levels,
than 0 V or VCC.
2. CPD is used to determine the dynamic power consumption, per inverter.
3. PD = VCC 2 fi (CPD + CL) where fi = input frequency, CL = output load capacitance, VCC = supply voltage.
