Applications Information
Logic Inputs
The logic control inputs can be driven up to +3.6V regardless of the supply voltage. For example, given a +3.3V supply, IN may be
driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail
Power-Supply Sequencing and Hot Plug Information
Proper power-supply sequencing is recommended for all CMOS devices. Always apply V
input/output or control pins.

Notes:
1. For Max. or Min. conditons, use appropriate value specifi ed under Electrical Characteristics for the applicable device.
2. Typical values are at V
3. Per TTL driven input (control inputs only); A and B pins do not contribute to I
4. This current applies to the control inputs only and represents the current required to switch internal capacitance at the specifi ed frequency. The A
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

and B inputs generate no signifi cant AC or DC currents as they transition, This parameter is not tested, but is guaranteed by design.
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
