QS3126 HIGH-SPEED CMOS QUADRUPLE BUS SWITCH WITH INDIVIDUAL ACTIVE INDUSTRIAL TEMPERATURE RANGE QUICKSWITCH PRODUCTS QS3126 HIGH-SPEED CMOS QUADRUPLE BUS SWITCH WITH INDIVIDUAL ACTIVE HIGH ENABLES FEATURES: DESCRIPTION: Enhanced N channel FET with no inherent diode to Vcc The QS3126 provides a set of four high-speed CMOS switches connect- Bidirectional switches connect inputs to outputs ing inputs to outputs. The low ON resistance of the QS3126 allows inputs Pin compatible with the 74126 function to be connected to outputs without propagation delay and without generating Zero propagation delay, zero ground bounce additional ground bounce noise. Individual active high enables (OE) are Undershoot clamp diodes on all switch and control inputs used to turn the switches on. The QS3126 is ideal for signal and control Available in QSOP and SOIC packages switching since the device adds no noise, ground bounce, propagation delay, or significant power consumption to the system. QuickSwitch devices provide an order of magnitude faster speed than conventional logic devices. APPLICATIONS: The QS3126 is characterized for operation at -40C to +85C. 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 FUNCTIONAL BLOCK DIAGRAM 1A 2A 3A 4A 1OE 2OE 3OE 4OE 1Y 2Y 3Y 4Y INDUSTRIAL TEMPERATURE RANGE MAY 2019 1 c 2019 Integrated Device Technology, Inc.
