PI3C3861QE

PI3C3861 2.5V/3.3V, High Bandwidth, Hot-Insertion, 10-Bit, 2-Port, Bus Switch Features Description • • • • • • • • The PI3C3861 is a 10-bit, 2.5volt or 3.3 volt, 2-port bus switch designed with a low On-Resistance (5-ohm) allowing inputs to be connected directly to outputs. The bus switch creates no additional propagational delay or additional ground bounce noise. The switches are turned ON by the Bus Enable (BE) input signal. This device is very userful in switching signals that have high bandwidth (>400 MHz). Near-Zero propagation delay 5-ohm switches connect inputs to outputs High bandwidth (>400 MHz) Rail-to-rail 2.5V or 3.3V switching 5V I/O Tolerant 2.5V Supply Voltage Operation Permits Hot-Insertion Packaging (Pb-free & Green Available): – 24-pin 150-mil wide plastic QSOP (Q) – 24-pin 173-mil wide plastic TSSOP (L) Applications • High bandwidth data switching • Hot Docking Block Diagram Pin Configuration A0 B0 A9 B9 BE Truth Table(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. Measured by the voltage drop between A and B pin at indicated current through the switch. On-Resistance is determined by the lower of the voltages on the two (A,B) pins.

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. 3WITCHING#HARACTERISTICSOVER6/PERATING2ANGE Parameters Description Test Conditions Com. Min.

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. 3WITCHING#HARACTERISTICSOVER6/PERATING2ANGE Parameters Description tPLH tPHL Delay(1,2) Propagation Ax to Bx, Bx to Ax tPZH tPZL Bus Enable Time BE to Ax or Bx tPHZ tPLZ Bus Disable Time BE to Ax or Bx Test Conditions Com.
