1. Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs of the

same device switching in the same direction, either HIGH or LOW (tOSLH = | tPLHm - tPLHn|, tOSHL = | tPHLm - tPHLn|).

2. Parameter guaranteed by design.

1. CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current

consumption without load. (Refer to Section 5: Test circuit). Average operating current can be obtained by the following

equation. ICC(opr) = CPD x VCC x fIN + ICC/6 (per gate).
