Notes
3. CL includes probe and jig capacitance.
4. All input pulses are supplied by generators having the following characteristics: PRR < 100 MHz, Z0 = 50Ω, tR < 2.5 ns, tF < 2.5 ns.
5. The outputs are measured one at a time with one transition per measurement.
6. TPLH and TPHL are the same as tpd.
