QS3126
HIGH-SPEED CMOS
QUADRUPLE BUS SWITCH WITH
INDIVIDUAL ACTIVE HIGH ENABLES
FEATURES:
DESCRIPTION:
• Enhanced N channel FET with no inherent diode to Vcc
• Bidirectional switches connect inputs to outputs
• Pin compatible with the 74’126 function
TheQS3126providesasetoffourhigh-speedCMOSswitchesconnect-
ing inputs to outputs. The low ON resistance of the QS3126 allows inputs
tobeconnectedtooutputswithoutpropagationdelayandwithoutgenerating
additional ground bounce noise. Individual active high enables (OE) are
used to turn the switches on. The QS3126 is ideal for signal and control
switching since the device adds no noise, ground bounce, propagation
delay, or significant power consumption to the system.
• Zero propagation delay, zero ground bounce
• Undershoot clamp diodes on all switch and control inputs
• Available in QSOP and SOIC packages
QuickSwitch devices provide an order of magnitude faster speed than
conventionallogicdevices.
The QS3126 is characterized for operation at -40°C to +85°C.
APPLICATIONS:
• Active high enabling
• Hot-swapping, hot-docking
• Voltage translation (5V to 3.3V)
• Power conservation
• Capacitance reduction and isolation (mass storage, work
stations)
• Logic replacement (data processing)
• Clock gating
• Bus isolation
