PI3CH3345 8-Bit Bus Switch, 2-Enable High or Low 1.8V/2.5V/3.3V, High-Bandwidth, Hot Plug Features Description Near-Zero propagation delay The PI3CH3345 is a Low-voltage, 8-channel switch 5-ohm switches connect inputs to outputs designed with fast enables. The switch creates no High signal passing bandwidth (500 MHz) additional ground bounce noise or propagation delay. Beyond Rail-to-Rail switching The PI3CH3345 device has two active LOW enables. It is very useful in switching signals that have - 0 to 5V switching with 3.3V power supply - 0 to 3.3V switching with 2.5V power supply high bandwidth (500 MHz). 5V I/O tolerant with supply in OFF and ON state 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): -20-pin 173-mil wide plastic TSSOP (L) Pin Description -20-pin TQFN(ZH) Pin No Pin Name Description Pin Configuration 1111111 1, 19 Switch Enable EN, EN 2-9 A0-A7 A Ports 11-18 B7-B0 B Ports 10 GND Ground 20 V Power CC (1) Truth Table EN B0-B7 EN Function Hi-Z L H Disconnect A0-A7 H H Connect TSSOP TQFN A0-A7 L L Connect A0-A7 H L Connect Note: Block Diagram 1.
