NOTES:

1. For conditions shown as Min. or Max., use the appropriate values specified under DC Electrical Characteristics.

2. Per TTL-driven input (VIN = 3.4V, control inputs only). A, B, and AB pins do not contribute to ∆Icc.

3. This current applies to the control inputs only and represents the current required to switch internal capacitance at the specified frequency. The A, B, and AB inputs generate

no significant AC or DC currents as they transition. This parameter is guaranteed but not production tested.

NOTES:

1. Minimums are guaranteed but not production tested.

2. 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

is of the order of 0.25ns at CL = 50pF. Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to the

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.
