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. tPLH and tPHL are the same as tpd.
