CL includes probe and jig capacitance. B. 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. C. All input pulses are supplied by generators having the following characteristics: PRR v10 MHz, ZO = 50 Ω, dv/dt ≥ 1 V/ns, dv/dt ≥1 V/ns. D. The outputs are measured one at a time, with one transition per measurement. E. tPLZ and tPHZ are the same as tdis. F. tPZL and tPZH are the same as ten. G. tPLH and tPHL are the same as tpd. H. VCCI is the VCC associated with the input port. I. VCCO is the VCC associated with the output port. 1.5 V ± 0.1 V 1.8 V ± 0.15 V 2.5 V ± 0.2 V 3.3 V ± 0.3 V 2 k Ω 1 k Ω 500 Ω 500 Ω VCCO RL 0.1 V 0.15 V 0.15 V 0.3 V VTP CL 15 pF 30 pF 30 pF 30 pF Figure 2.
