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 resis-
tance of the switch and a load capacitance of 50pF, when driven by an ideal voltage source (zero output impedance).

Notes:
1. CL includes probe and jig capacitance.
2. 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.
• All input pulses are supplied by generators having the following characteristics: PRR < 10MHz, Zo = 50Ω, tr ≤ 2.5ns, tf ≤ 2.5ns.
• The outputs are measured one at a time with one transition per measurement.
• tPLZ and tPHZ are the same as tdis.
• tPZL and tPZH are the same as ten.
• tPLH and tPHL are the same as tpd.
