CL includes probe and jig capacitance. B. All input pulses are supplied by generators having the following characteristics: PRR ≤ 10 MHz, Zo = 50 Ω, tr ≤ 3 ns, tf ≤ 3 ns. For testing pulse duration: tr = tf = 1 to 3 ns. Pulse polarity can be either high-to-low-to-high or low-to-high-to-low. C. 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. D. The outputs are measured one at a time with one transition per measurement. Figure 1. Load Circuit and Voltage Waveforms |
