PI3CH400 4-Bit Bus Switch, Enable Low 1.8V/2.5V/3.3V, High-Bandwidth, Hot Plug Features Description Near-Zero propagation delay The PI3CH400 is a low voltage, 4-channel switch 5-ohm switches connect inputs to outputs designed with fast individual enables. The switch High signal passing bandwidth (500 MHz) introduces no additional ground bounce noise or Beyond Rail-to-Rail switching additional propagation delay. - 0 to 5V switching with 3.3V power supply The PI3CH400 device has active low enables. It is - 0 to 3.3V switching with 2.5V power supply very useful in switching signals that have high 5V I/O tolerant with supply in OFF and ON state bandwidth (500 MHz). 1.8V, 2.5V and 3.3V supply voltage operation Applications Hot Insertion Capable High Bandwidth Data Switching Industrial Operating Temperature: 40C to +85C Hot-Docking 8kV ESD Protection (human body model) Analog Signal Switching Latch-up Performance: >200mA per JESD17 Differential Signal Switching Packaging (Pb-free & Green available): Block Diagram -14-pin TSSOP (L) -14-pin QFN (ZB) Pin Configuration QFN Pin Description (1) Truth Table Pin No Pin Name Description 1111111 1, 4, 10 Switch Enables EN EN , EN 0, 1 2 EN Ax Bx V x Function CC (2) 2, 5, 9, 12 A0-A3 A Ports X Hi-Z Hi-Z GND Disconnect 3, 6, 8, 11 B0-B3 B Ports H Hi-Z Hi-Z V Disconnect CC 14 V Power CC L Bx Ax V Connect CC 7 GND Ground Note: 1.
