HIGH-SPEED CMOS  
SYNCHROSWITCH™  
32:16 MUX/DEMUX  
DESCRIPTION:  
FEATURES:  
The QS34XS257 is a high-speed CMOS quad 32:16 multiplexer/  
demultiplexer. It is organized as four independent quad 2:1 mux/demux  
blocks. Portselectionandconnection, controlledbySELsignals, canbe  
eitherasynchronous orsynchronous. Inthe synchronous mode, the Aor  
BporttoYportconnectionis updatedonthe risingedge ofthe inputclock  
CLK. Once the port-to-port connection is made, data flow can be bi-  
directionalwithatypical250pspropagationdelaythroughtheswitch. Clock  
Enable,overridingAsynchronous Enable,andAsynchronous Selectcon-  
trols provideadditionaldesignflexibility.  
• Enhanced N channel FET with no inherent diode to Vcc  
• Bidirectional signal flow  
• Flow-through pinout  
Zero propagation delay, zero ground bounce  
• 16 banks of 2:1 Mux/Demux  
• Port select synchronous to the clock  
• Clock enable and asynchronous enable  
Undershoot clamp diodes on all switch and control inputs  
Asynchronous SEL option  
Synchronous controls easetimingconstraints inmanyhighspeeddata  
mux/demuxapplications, suchas bankinterleaving. The QS34XS257is  
available inthe space-saving,80-pindual-in-line MillipaQpackage.  
The QS34XS257 is characterized for operation at -40°C to +85°C.  
• Break-before-make feature  
• Bus-hold eliminates floating bus lines and reduces static power  
consumption  
Available in 80-pin Millipaq package
