NOTES: A. CL includes probe and jig capacitance.

B. All input pulses are supplied by generators having the following characteristics: PRR

≤ 10 MHz, ZO = 50 Ω, tr ≤ 2.5 ns, tf ≤ 2.5 ns.

C. The outputs are measured one at a time, with one transition per measurement.

D. tPLH and tPHL are the same as tsov and tovn.

E. tPLH and tPHL are the same as tmpd, tsov, and tovm.
