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. On 1AN & 1BN (Data Inut) pins only.
4. Measured by the voltage drop between I and Y pin at indicated current through the switch. ON resistance is determined by
the lower of the voltages on the two (I,Y) pins.
5. This parameter is determined by device characterization but is not production 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.
ApplicationInformation
Logic Inputs
Logic control inputs can be driven up to +5.5V regardless of the supply voltage. For example, given a 5.0V supply, the control or
select pins may be driven low to 0V and high to 5.5V. Driving the control or select pins Rail-toRail® 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.
