CPD is used to determine the dynamic power dissipation (PD in µW). PD = CPD × VCC2 × fi + ∑ (CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in V; ∑ (CL × VCC2 × fo) = sum of outputs. 2. For HC1G the condition is VI = GND to VCC. For HCT1G the condition is VI = GND to VCC − 1.5 V. NAME AND FUNCTION data inputs ground (0 V) data output positive supply voltage H = HIGH volta...
