Notes:

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

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

3. Per TTL driven input (control inputs only); A and B pins do not contribute to Icc.

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.

Notes:

1. See Test Circuits and Waveforms.

2. This parameter is guaranteed by design but not tested.

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

the load capacitance.
