7 Parameter Measurement Information
- Phase relationships between waveforms were chosen arbitrarily. All input pulses are supplied by generators having the following characteristics: PRR ≤ 1 MHz, ZO = 50 ?, tt < 6 ns.
- The outputs are measured one at a time, with one input transition per measurement.
A. CL= 50 pF and
includes probe and jig capacitance.
Figure 7-1 Load Circuit
A. The maximum between
tPLH and tPHL is used for
tpd.

Propagation Delays
A. tt is the
greater of tr and tf.
