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 = 3.3V, +25°C ambient.
3. Per TTL driven input (V_IN = 3.0V, control inputs only); A and B pins do not contribute to I_CC.
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 circuit and waveforms.
2. This parameter is guaranteed but not tested.
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.
