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 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.

Applications Information
Logic Inputs
The logic control inputs can be driven up to +5.5V regardless of the supply voltage. For example, given a +5.0V supply, IN may be
driven low to 0V and high to 5.5V. Driving IN Rail-to-Rail® minimizes power consumption. Proper power-supply sequencing is
recommended for all CMOS devices. Always apply V before applying Vbias and signals to the input/output pins.
