Notes:

1. For Max. or Min. conditions, use appropriatr 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.

4. This current applies to the contol inputs only and represents the current required to switch internal capacitance at the specified frequency. The A and

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

Notes:

1. This parameter is guaranteed but not tested on Propogation Delays.

2. This bus switch contributes no propogational delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time

constant for tjhe switch alone is of the order of 0.25ns for 50pF load. Since this time constnt is much smaller than the rise/fall times of typical driv-

ing signals, it adds very little propogational delay to the system. Propogatioonal delayy 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 tthe 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 devicces. Always apply VCC and GND

before applying signals to input/output or control pins.
