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). I and Y 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 I

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

NOTES:

1. Minimums guaranteed but not tested.

2. This parameter is guaranteed but not 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 for 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.
