NOTE:
1. All typical values are measured at Tamb = 25°C and VCC = 5.0V
2. 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 50pF, 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. All input pulses are supplied by generators having the following
characteristics: PRR
≤ 10 MHz, ZO = 50 , tr ≤ 2.5 ns, tf ≤ 2.5 ns.
2. The outputs are measured one at a time with one transition per
measurement.
