Notes:

1. See test circuit and waveforms.

2. This parameter is guaranteed by design.

3. The bus switch contributes no propagational delay other than the RC delay of the ON resistance of the switch and the load

capacitance. The time constant for the switch alone is of the order of 0.75ns for 50pF load. Since this time constant is much smaller

than the rise/fall times of typical driving signals, it adds very little propagational delay to the system. Propagational delay of the

bus switch when used in a system is determined by the driving circuit on the driving side of the switch and its interaction with the

load on the driven side.

Notes:

3. 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.

4. All input impulses are supplied by generators having the following characteristics: PRR

5. The outputs are measured one at a time with one transition per measurement.
