PI5C3861 10-Bit, 2-Port Bus Switch Features: Description: Near-Zero propagation delay Pericom Semiconductors PI5C3861 is a 10-bit, 2-port bus switch designed with a low On-Resistance (5) allowing inputs to be 5 switches connect inputs to outputs connected directly to outputs. The bus switch creates no additional Direct bus connection when switches are ON propagation delay or additional ground bounce noise. The switches Ultra Low Quiescent Power (0.2A typical) are turned ON by the Bus Enable (BE) input signal. Ideally suited for notebook applications Packaging (Pb-free & Green available): 24-pin, 150-mil wide plastic QSOP (Q) Block Diagram Pin Con guration NC 1 24 V CC A0 2 23 BE A0 B0 A1 3 22 B0 A2 4 21 B1 A3 5 20 B2 A4 6 19 B3 7 18 A5 B4 A9 B9 8 17 A6 B5 9 16 A7 B6 10 15 A8 B7 11 14 A9 B8 12 13 GND B9 BE Pin Description Pin Name Description BE Bus Enable Input (Active LOW) (1) A09 Bus A Truth Table B09 Bus B Function BE A09 GND Ground Disconnect H Hi-Z V Power CC Connect L B09 Note: NC No Connect 1.
