Notes:

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

2. Typical values are at Vcc = 3.3V, +25°C ambient.

4. This current applies to the control inputs only and represent the current required to switch internal capacitance at the specified

frequency. The A and B inputs generate no significant AC or DC currents as they transition. This parameter is not tested, but is

guaranteed by design.

Switching Characteristics over 3.3V Operating Range

Notes:

1. See test circuit and waveforms.

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

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

0.25ns 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.
