PI3B3245 3.3V, Hot Insertion, TM 8-Bit, 2-Port NanoSwitch Features Description Near-Zero propagation delay Pericom Semiconductors PI3B3245 is a 3.3V 8-bit, 2-port bus switch designed with a low On-Resistance (5-ohm) allowing in- 5-ohm switches connect inputs to outputs puts to be connected directly to outputs. e Th bus switch creates Fast Switching Speed: 4.5ns (max.) no additional propagational delay or additional ground bounce Ultra-Low Quiescent Power (0.2A Typical) noise. e Th switches are turned ON by the Bus Enable (BE) input signal. Ideally suited for notebook applications TTL-compatible control of inputs levels ESD protection (2kV Human Body Model and 200V Machine Model) Packaging (Pb-free & Green): 20-pin QSOP (Q) 20-pin TSSOP (L) 20-pin SOIC (S) Block Diagram Pin Configuration A0 SW B0 NC 1 2 0 Vcc A0 2 1 9 BE A1 3 1 8 B0 SW A 7 B7 4 1 7 A2 B1 A3 5 1 6 B2 A4 6 1 5 B3 SW 7 1 4 A5 B4 BE A6 8 1 3 B5 AA B 9 1 2 A7 B6 1 0 1 1 GND B7 BE Truth Table Pin Description Function BE A0-7 Pin Name Description Disconnect H Hi-Z BE Bus Enable Input (Active LOW) Connect L B0-7 A0-7 Bus A Note: B0-7 Bus B H = High Voltage Level, L = Low Voltage Level, Hi-Z = High Impedance GND Ground Power V CC All trademarks are property of their respective owners. www.pericom.com PS8162i 12/08/10 10-0247 1PI3B3245 TM 3.3V, Hot Insertion, 8-Bit, 2-Port NanoSwitch Absolute Maximum Ratings Parameter Min.
