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 inputs only); A and B pins do not contribute to ICC.

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 VCC and GND before applying signals to

input/output or control pins.
