Notes:
1. For Max. or Min. conditons, 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 inputs only); A and B pins do not contribute to I
CC
.
4. This current applies to the control inputs only and represent 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.
PI3B32X384 Switching Characteristics over Operating Range
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 +3.6V 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 V
CC
and GND before applying signals to input/
output or control pins.
