capacitance, when driven by an ideal voltage source (zero output impedance).

Notes:
Figure 2. Load Circuit and Voltage Waveforms
1. C_L includes probe and jig capacitance.
2. Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control.
Waveform 2 is for an output with internal conditions such that the output is high except when disabled by the output control.
3. All input impulses are supplied by generators having the following characteristics: PRR ≤ MHz, Z_O = 50Ω, t_R ≤ 2.5ns, t_F ≤ 2.5ns.
4. The outputs are measured one at a time with one transition per measurement.
5. t_TPZ and t_PHZ are the same as t_DIS
6. t_PZL and t_PZH are the same as t_EN
7. t_PLH and t_PHL are the same as t_PD
