Notes:

1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.

Notes:

1. See test circuit and waveforms.

2. This parameter is guaranteed but not tested on Propagation Delays.

3. The bus switch contributes little 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 1.0ns for 30pF load. Propagation 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:

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.

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