6 / 11 page 74VCX16244 6/11 DYNAMIC SWITCHING CHARACTERISTICS (Ta = 25°C, Input tr =tf = 2.0ns, CL = 30pF, RL = 500Ω) 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. 2) 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 HIGH state. 3) Parameters guaranteed by design. AC ELECTRICAL CHARACTERISTICS (CL = 30pF, RL = 500Ω, Input tr =tf = 2.0ns) 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) TA =25°C Min.
