QuickSwitch® Products High-Speed CMOS QuickSwitch 16:8 Multiplexer
DESCRIPTION
QS3390 QS32390
Enhanced channel with inherent diode 16:8 multiplexer function with zero delay bidirectional switches connect inputs outputs Zero propagation delay, zero ground bounce power CMOS proprietary technology compatible control inputs Undershoot clamp diodes control switch pins Direct bidirectional connection mux, demux QS32390 version noise Available 28-pin SOIC (SO) QSOP
QS3390 QS32390 provide 16:8 multiplexer logic switch. resistance QS3390 allows inputs connected outputs without adding propagation delay without generating additional ground bounce noise. QS32390 adds internal resistor reduce reflection noise high-speed applications. enable inputs connect inputs common pin, respectively. multiplexer function used select route logic signals zero delay, isolate capacitance, form crossbar switches, etc. Mux/Demux devices provide order magnitude faster speed than equivalent logic devices.

Notes: Test Circuit Waveforms. Minimums guaranteed, production tested. This parameter guaranteed, production tested. time constant switch alone order 0.25ns QS3390 1.25ns QS32390 50pF. switch contributes propagation delay other than delay resistance switch load capacitance. Since this time constant much smaller than rise/fall times typical driving signals, adds very little propagation delay system. Propagation delay switch when used system determined driving circuit driving side switch interaction with load driven side.
