Pin Description
The PI3C32160 is a 16- to 32-bit demultiplexer bus switch. Industry
leading advantages include a propagation delay of 500ps, resulting
from 9 ohms channel resistance and low I/O capacitance. A port
demultiplexes to either 1B or 2B and the switch is bidirectional.

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 = 3.3V, TA = 25°C ambient and maximum loading.
3. Not more than one output should be shorted at one time. Duration of the test should not exceed one second.
4. Measured by the voltage drop between A and B pins at indicated current through the switch. ON resistance is determined by the
lower of the voltages on the two (A & B) 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.

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, the output enables
or select pins may be driven low to 0V and high to 3.6V. Driving IN Rail-to-Rail® minimizes power consumption.
Power-Supply Sequencing
Proper power-supply sequencing is recommended for all CMOS devices. It is recommended to always apply VCC before applying signals
to input/output or control pins.
Hot Insertion
For Datacom and Telecom applications that have 10 or more volts passing through the backplane or system bus, a high voltage from the
power supply may be seen at the device input pins during Hot Insertion. The PI3Cxxx devices have maximum limits of 5.5V and 120mA for
20ns. If the power is higher or applied for a longer period of time or repeatedly reaches the maximum limits, the devices can be damage.
