Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
2. Typical values are at V_CC = 3.0V, +25°C ambient.
3. Per LVTTL driven input (V_IN = 2.4V, control inputs only); A, B, C, and D pins do not contribute to I_CC.

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.
