16-Bit to 32-Bit, Demux PCI Hot-Plug Bus Switch with 2V Undershoot Protection
Product Description
Pericom Semiconductors PI5C series of logic circuits are produced using the Companys advanced submicron CMOS technology, achieving industry leading performance. The PI5C32161C is a 16- to 32-bit demultiplexer bus switch. It is intended for PCI Hot-Plug applications. Industry leading advantages include a propagation delay of 250ps, resulting from 5-Ohm channel resistance, and low I/O Capacitance. A port demultiplexes to either 1B and 2B or to both. The switch is bidirectional. Precharge bias voltage is provided on B ports to minimize live insertion noise. The A port can handle up to 2V undershoot during switch disable. Application Provides PCI Hot Plugging

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 = 5.0V, TA = 25C 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.

Per TTL driven input (VIN = 3.4V, control inputs only); A and B pins do not contribute to ICC. 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. 5. Values for these conditions are examples of the ICC formula. These limits are guaranteed but not tested.

Units
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 +5.5V regardless of the supply voltage. For example, given a +5.0V supply, IN may be driven low to 0V and high to 5.5V. Driving IN Rail-to-Rail(R) minimizes power consumption. Proper power-supply sequencing is recommended for all CMOS devices. Always apply VCC before applying signals to the bias voltage pin and the input/output or control pins.
