Notes:
1.
For Max. or Min. conditions, use appropriate value specied 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 specied frequency. The
A and B inputs generate no signicant AC or DC currents as they transition. This parameter is not tested, but is guaranteed by design.
Notes:
1.
This parameter is guaranteed but not tested on Propagation Delays.
2.
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, control inputs
may be driven low to 0V and high to 5.5V. Driving control inputs Rail-to-Rail minimizes power consumption.
Power-Supply Sequencing
Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC before applying signals to the input/output
or control pins.
