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 (control input only); A and B pins do not contribute to I_CC.

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 +3.6 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® minimizes power consumption.
Power-Supply Sequencing and Hot-Plug Information
Proper power-supply sequencing is recommended for all CMOS devices. Always apply V_CC and GND before applying signals to
input/output or control pins.
