DYNAMIC SWITCHING CHARACTERISTICS
1) Number of outputs defined as ”n”. Measured with ”n-1” outputs switching from HIGH to LOW or LOW to HIGH. The remaining output is
measured in the LOW state.
AC ELECTRICAL CHARACTERISTICS
1) Skew is defined as the absolute value ofthe difference between the actual propagation delayfor anytwo outputs of the same device switch-
ing in the same direction, either HIGH or LOW (t

CAPACITIVE CHARACTERISTICS
1) C
is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to TestCircuit). Averageoperating current canbe obtained by the following equation. I
