DESCRIPTION
QS3384 QS32384
Enhanced channel with inherent diode bidirectional switches connect inputs outputs Zero propagation delay (QS3384), zero ground bounce Undershoot clamp diodes switch control pins QS32384 version noise enables control five bits each Available TSSOP, SOIC, QSOP HQSOP QS3384 QS32384 provide highspeed CMOS, TTL-compatible switches. resistance QS3384 allows inputs connected outputs without adding propagation delay without generating additional ground bounce. banks switches controlled independent Enable (BE) signals. QS32384 adds internal series resistor with each switch 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 QS3384 1.25ns QS3284 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.
