5 Parameter Measurement Information

SN54ACT74 SN74ACT74 Load Circuit and Voltage Waveforms Figure 5-1 Load Circuit and Voltage Waveforms. CL includes probe and jig capacitance. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1MHz, ZO = 50Ω, tr ≤ 2.5ns, tf ≤ 2.5ns. The outputs are measured one at a time with one input transition per measurement.
Note:

A. CL includes probe and jig capacitance.

B. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1MHz, ZO = 50Ω, tr ≤ 2.5ns, tf ≤ 2.5ns.

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