PI3C32X245 2.5V/3.3V, High Bandwidth, Hot Insertion 16-Bit, 2-Port, Bus Switch Features Description Near-Zero propagation delay Pericom Semiconductors PI3C32X245 is a 2.5V or 3.3V 16-bit, 2-port bus switch designed with a low On-Resistance (5-ohm) al- 5-ohm switches connect inputs to outputs lowing inputs to be connected directly to outputs. e Th bus switch Permits Hot Insertion creates no additional propagational delay or additional ground Capable of Hot-Swapping bounce noise. e Th switches are turned ON by the Bus Enable (BE ) input signal. It is very useful in switching signals that have N 5V I/O Tolerant high bandwidth (>400 MHz). 2.5V Supply Voltage Operation Rail-to-Rail 3.3V or 2.5V Switching High Bandwidth Operation (>400 MHz) Packaging (Pb-free & Green): 40-pin, 150-mil-wide plastic BQSOP (B) Block Diagram Pin Configuration A0 B0 NC 1 40 VCC A0 2 39 BE1 A1 3 38 B0 A7 B7 A2 B1 4 37 A3 5 36 B2 A4 6 35 B3 BE1 A5 B4 7 34 A6 8 33 B5 A8 B8 A7 9 32 B6 GND 10 31 B7 NC 11 30 VCC A15 B15 A8 12 29 BE2 A9 B8 13 28 A10 14 27 B9 BE2 A11 15 26 B10 A12 16 25 B11 A13 17 24 B12 (1) Truth Table A14 B13 18 23 A15 19 22 B14 Function BE A0-15 N GND 20 21 B15 Disconnect H Hi-Z Connect L B0-15 Note: H = High Voltage Level Pin Description L = Low Voltage Level Pin Name Description Hi-Z = High Impedance Bus Enable Input (Active LOW) BE N A0-15 Bus A B0-15 Bus B All trademarks are property of their respective owners. www.pericom.com PS8401E 01/11/11 11-0008 1PI3C32X245 2.5V/3.3V, High Bandwidth, Hot Insertion, 16-Bit, 2-Port, Bus Switch Absolute Maximum Ratings Parameter Min.
