Table 7: Dynamic Switching Characteristics

1) Number of output 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.

Table 8: AC Electrical Characteristics

1) Skew is defined as the absolute value of the difference between the actual propagation delay for any two outputs of the same device switch-

ing in the same direction, either HIGH or LOW (tOSLH = | tPLHm - tPLHn|, tOSHL = | tPHLm - tPHLn|

2) Parameter guaranteed by design

Table 9: Capacitive Characteristics

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 Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/n (per circuit)
