4. This current applies to the control inputs only and represents the current required to switch internal capacitance at the specified frequency. The A and B pins generate no significant

AC or DC currents as they transition. This parameter is guaranteed but not production tested.

3. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone

system. 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.
