CL includes probe and jig capacitance. B. In the examples above, the phase relationships between inputs and outputs have been chosen arbitrarily. C. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, ZO = 50 Ω, and: For Series 54/74, tr ≤ 7 ns, tf ≤ 7 ns. For Series 54S/74S, tr ≤ 2.5 ns, tf ≤ 2.5 ns. D. The outputs are measured one at a time with one input transition per measurement. 1.5 V 1.5 V Input tPLH In-Phase Output 3 V 0 V 1.5 V 1.5 V VOH VOL tPHL 1.5 V 1.5 V VOH VOL tPHL tPLH Out-of-Phase Output VOLTAGE WAVEFORMS PROPAGATION DELAY TIMES Figure 1.
