IDTQS3VH245  
2.5V / 3.3V 8-BIT HIGH  
BANDWIDTH BUS SWITCH  
FEATURES:  
DESCRIPTION:  
• N channel FET switches with no parasitic diode to VCC  
– Isolationunderpower-offconditions  
– No DC path to VCC or GND

– 5V tolerant in OFF and ON state  
• 5V tolerant I/Os  
• Low RON - 4typical  
• Flat RON characteristics over operating range  
• Rail-to-rail switching 0 - 5V  
Thecombinationofnear-zeropropagationdelay,highOFFimpedance,and  
over-voltage tolerance makes the QS3VH245 ideal forhigh performance  
communicationsapplications.  
• Bidirectional dataflow with near-zero delay: no added ground  
bounce  
• Excellent RON matching between channels  
• VCC operation: 2.3V to 3.6V  
TheQS3VH245ischaracterizedforoperationfrom-40°Cto+85°C.  
• High bandwidth - up to 500MHz  
• LVTTL-compatible control Inputs  
• Undershoot Clamp Diodes on all switch and control Inputs  
• Low I/O capacitance, 4pF typical  
• Available in QSOP, SOIC, and TSSOP packages  
APPLICATIONS:  
• Hot-swapping  
• 10/100 Base-T, Ethernet LAN switch  
• Low distortion analog switch  
• Replaces mechanical relay  
• ATM 25/155 switching  
• Bus switching and isolation
