QUICKSWITCH® PRODUCTS  
HIGH-SPEED CMOS SYNCHRO-  
IDTQS3ST253  
SWITCH™ DUAL 4:1 MUX/DEMUX  
WITH ACTIVE TERMINATORS  
DESCRIPTION:  
FEATURES:  
TheQS3ST253isahigh-speedCMOS dual4:1 multiplexer/demultiplexer  
withactiveterminators(bus-holdcircuits)onthedemuxside. Portselection  
andconnection, controlledbySELsignals, canbeeitherasynchronousor  
synchronous. In the synchronous mode, the A, B, C, or D port to Y port  
connection is updated on the rising edge of the input clock CLK. Once the  
port-to-portconnectionismade,dataflowcanbebi-directionalwithatypical  
250ps propagation delay through the switch. Clock Enable, overriding  
Asynchronous Enable, and Asynchronous Select controls provide addi-  
tionaldesignflexibility.  
• Enhanced N channel FET with no inherent diode to Vcc  
• Bidirectional signal flow  
• Flow-through pinout  
• Zero propagation delay, zero ground bounce  
• 2 banks of 4:1 Mux/Demux  
• Port select synchronous to the clock  
• Undershoot clamp diodes on all switch and control inputs  
• Clock enable and Asynchronous enable  
• “Bus-hold” terminators on the Demux side  
• Asynchronous SEL option  
The bus-hold circuits latch the last data driven on the demux side,  
providinginfiniteholdtimeandglitch-freesignaltransitions. Synchronous  
controlsandbus-holdeasetimingconstraintsinmanyhighspeeddatamux/  
demux applications, such as bank interleaving.  
• Break-before-make feature  
• Bus-hold eliminates floating bus lines and reduces static power  
consumption  
The QS3ST253 can be used in 5V to 3.3V translation.  
• Available in QSOP package  
APPLICATIONS:  
• Video, audio, graphics switching, muxing
