PULSE DURATIONS
NOTES: A. CL includes probe and test-fixture capacitance.
B. 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.
C. For clock inputs, fmax is measured when the input duty cycle is 50%.
D. The outputs are measured one at a time, with one input transition per measurement.
E. tPLH and tPHL are the same as tpd.
