1. Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device.
The specification applies to any outputs switching in the same direction, either HIGHâtoâLOW (tOSHL) or LOWâtoâHIGH (tOSLH); parameter
guaranteed by design.

2. CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load.
Averageoperating current can be obtained by the equation: ICC(OPR) = CPD VCC fin + ICC / 4 (per gate). CPD is used to determine the noâload
dynamic power consumption; PD = CPD VCC2 fin + ICC VCC.
