4 / 12 page 74LCX139 4/12 Table 6: DC Specifications Table 4: 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. Table 7: 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 Symbol Parameter Test Condition Value Unit VCC (V) -40 to 85 °C -55 to 125 °C Min.
