QuickSwitch® Products High-Speed CMOS 10-Bit Switch with Flow-Thru Pinout
DESCRIPTION
QS3861 QS32861
Enhanced channel with inherent diode bidirectional switches connect inputs outputs Zero propagation delay (3861), zero ground bounce Undershoot clamp diodes switch control pins QS3861 available SOIC, QSOP TSSOP QS32861 available SOIC QSOP QS32861 version noise
QS3861 QS32861 each provide high speed CMOS, TTL-compatible switches. resistance QS3861 allows inputs connected outputs without adding propagation delay without generating additional ground bounce noise. Enable (BE) signal turns switches QS32861 includes internal series termination resistors reduce reflection noise high speed applications. When closed, switch acts source (series) termination driver connected
APPLICATIONS:
Hot-swapping, hot-docking (Application Note AN-13) Voltage translation 3.3V; Application Note AN-11) Power conservation Capacitance reduction isolation isolation Clock gating

Notes: Test Circuit Waveforms. Minimums guaranteed production tested. This parameter guaranteed, production tested. time constant switch alone order 0.25ns QS3861 1.25ns QS32861 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.
