PI3C3384 2.5V/3.3V, High Bandwidth, Hot Insertion 10-Bit, 2-Port, Bus Switch Description Features Pericom Semiconductor’s PI3C3384 is a 2.5V or 3.3V, high bandwidth 10-bit, 2-port bus switches designed with a low OnResistance 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. Two bus enable signals are provided, one for each of the upper and lower five bits of the two 10-bit buses. • Near-Zero propagation delay • 5-ohm switches connect inputs to outputs • High Bandwidth (>400 MHz) • Permits Hot Insertion. • Rail-to-Rail, 3.3V or 2.5V Switching • 5V I/O Tolerant • 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 A4 B4 A5 B5 A9 B9 BEA B0 A0 A1 B1 B2 A2 A3 B3 B4 A4 GND BEA BEB Truth Table(1) Function BEA Disconnect H Connect L Connect H Connect L BEB H H L L B0-B4 Hi-Z A0-A4 Hi-Z A0-A4 Pin Description Pin Name BEA, BEB A0 - A9 B0 - B9 GND VCC B5-B9 Hi-Z Hi-Z A5-A9 A5-A9 Note: 1.

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. 4.

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. 11-0008 3 PS8757G 11/25/10 PI3C3384 2.5V/3.3V, High Bandwidth, Hot Insertion 10-Bit, 2-Port, Bus Switch 4.0 VCC = 3.3V 3.8V 3.6V 3.4V 3.2V 3.0V 3.1V 2.9V 2.7V 2.5V VOUT, (V) 2.3V 2.8V 2.0 0.0 0.0 1.0 2.0 VIN, (V) 3.0 4.0 5.0 Output Voltage vs. Input Voltage over Various Supply Voltages Switch Position Test Circuit 6V VCC Open 500Ω VIN Pulse Generator VOUT 50pF 500Ω CL Enable and Disable Timing 3V 1.6V Control Input 1.5V Same Phase Input Transisiton 0V Switch Output Normally Low 0V 3V tPLH 3V 1.5V t PZH 0.3V VOL Output t PZH Switch GND 1.5V 0.3V 0V tPHL VOH 1.5V 1.5V VOL VOH tPLH tPHL 0V Opposite Phase Input Transisiton 1.
