NOTE:
1. The propagation delay is the calculated RC time constant of the typical on-state resistance of the switch and the specified load capacitance,
when driven by an ideal voltage source (zero output impedance).

Note:
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.

NOTES:
1. tPLZ and tPHZ are the same as tdis.
2. tPZL and tPZH are the same as ten.
3. tPLH and tPHL are the same as tpd.

NOTES:
1. All input pulses are supplied by generators having the following
characteristics: PRR ≤ 10 MHz, ZO = 50 Ω, tr ≤ 2.5 ns, tf ≤ 2.5 ns.
2. The outputs are measured one at a time with one transition per
measurement.
