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
