LOAD CIRCUIT
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 , tr = 6 ns, tf = 6 ns.
C. The outputs are measured one at a time with one input transition per measurement.
D. For clock inputs, fmax is measured when the input duty cycle is 50%.
E. tPLH and tPHL are the same as tpd.
