NOTES: A.

C includes probe and test-fixture 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 ≤ 1 MHz, Z = 50 Ω, t = 3 ns, t = 3 ns.

Phase relationships between waveforms are arbitrary.

D. For clock inputs, f is measured with the input duty cycle at 50%.
