PI3C3384 2.5V/3.3V, High Bandwidth, Hot Insertion 10-Bit, 2-Port, Bus Switch Features Description Pericom Semiconductor s PI3C3384 is a 2.5V or 3.3V, high Near-Zero propagation delay bandwidth 10-bit, 2-port bus switches designed with a low On- 5-ohm switches connect inputs to outputs Resistance allowing inputs to be connected directly to outputs. High Bandwidth (>400 MHz) The bus switch creates no additional propagational delay or Permits Hot Insertion. additional ground bounce noise. The switches are turned ON by Rail-to-Rail, 3.3V or 2.5V Switching the Bus Enable (BE) input signal. Two bus enable signals are provided, one for each of the upper and lower five bits of the 5V I/O Tolerant two 10-bit buses. 2.5V Supply Voltage Operation Packaging (Pb-free & Green): 24-pin 150-mil wide plastic QSOP (Q) Applications High Bandwidth Data switching Hot Docking Block Diagram Pin Configuration A0 B0 VCC BEA 1 24 B9 B0 2 23 A4 B4 3 A9 A0 22 A1 4 A8 21 B8 B1 5 20 B7 B2 6 19 A5 B5 A2 7 A7 18 A3 8 A6 17 9 B6 B3 16 A9 B9 B4 10 B5 15 11 A5 A4 14 12 GND 13 BEB BEA BEB (1) Pin Description Truth Table Pin Name Description Function BE BE B0-B4 B5-B9 A B BE , BE Bus Enable Inputs (Active LOW) Disconnect H H Hi-Z Hi-Z A B A0 - A9 Bus A Connect L H A0-A4 Hi-Z B0 - B9 Bus B Connect H L Hi-Z A5-A9 GND Ground Connect L L A0-A4 A5-A9 Note: V Power CC 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 = 25C 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 volt- ages on the two (A,B) pins. 4. This parameter is determined by device characterization but is not production tested. PS8757G 11/25/10 11-0008 2
