QUALITY SEMICONDUCTOR, INC.
QuickSwitch® Products 3.3V Quad Mux/Demux Swap Applications (HotSwitchTM)
DESCRIPTION
QS3VH257
channel switches with parasitic diode path tolerant sate Bidirectional dataflow with near-zero delay added ground bounce typical Flat characteristics over operating range Excellent matching between channels capacitance LVTTL-compatible control inputs Undershoot clamp diodes control switch inputs Available QSOP, SOIC (S1) TSSOP packages
QS3VH257 HotSwitch Quad mulitplexer/ demultiplexer specially designed hot-swapping multiplexing 3.3V supply environment. QS3VH257 very resistance resulting under 200ps propagation delay through switch. state, switches 5V-tolerant offer very high impedance terminals. combination near-zero propagation delay, high impedance, over-voltage tolerance makes QS3VH257 ideal swapping applications. resistance QS3VH257 makes ideal Compact swapping environment.

Notes: Test Circuit Waveforms. Minimums guaranteed production tested. This parameter guaranteed, production tested. switch contributes propagation delay other than delay resistance switch load capacitance. time constant switch alone order 0.20ns 50pF. 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. Minimums guaranteed, production tested. Maximum frequency bidirectional data flow. Maximum toggle frequency control input.
