5 Parameter Measurement Information
Load Circuit and Voltage Waveforms
Figure 5-1 Load Circuit 
Figure 5-2 Voltage Waveforms Pulse Durations 
Figure 5-3 Voltage Waveforms Setup and Hold and Input Rise and Fall Times
Figure 5-4 Voltage Waveforms Propagation Delay and Output Transition TimesNote:
- CL includes probe and test-fixture capacitance.
- Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, ZO = 50 Ω, tr = 6 ns, tf = 6 ns.
- For clock inputs, fmax is measured when the input duty cycle is 50%.
- The outputs are measured one at a time, with one input transition per measurement.
- tPLH and tPHL are the same as tpd.
