NOTES:
1. This parameter is warranted but not production tested. The propagation delay is based on the RC time constant of the typical on-state
resistance of the switch and a load capacitance of 50 pF, 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.
