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 Ω, 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.
