Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device type.
2. Typical values are at VCC = 5.0V, TA = 25°C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
4. Measured by the voltage drop between A and B pins at indicated current through the switch. ON resistance is determined by the
lower of the voltages on the two (A & B) pins.
5. This parameter is determined by device characterization but is not production tested.

Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
2. Typical values are at VCC = 5.0V, +25°C ambient.
3. Per TTL driven input (VIN = 3.4V, control inputs only); A and B pins do not contribute to ICC.
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.
5. Values for these conditions are examples of the Icc formula. These limits are guaranteed but not tested.

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 25pF 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.
