Notes:
1. For Max. or Min. conditions, use appropriate value specified under Electrical Characteristics for the applicable device.
2. Typical values are at VCC = 3.3V, +25°C ambient.
3. Per TTL driven input (control input only); A and B pins do not contribute to ICC.

Notes:
1. See test circuit and wave forms.
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 ca-
pacitance. The time constant for the switch alone is of the order of 0.25 ns for 50 pF 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 +3.6V 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 minimizes power consumption.
Power-Supply Sequencing and Hot-Plug Information
Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC and GND before applying signals to
input/output or control pins.
