QUALITY Semiconductor QS3126 Bus Switch Quad 1-IN 16-Pin QSOP DIP High-speed CMOS Quadruple Bus Switch With Individual Active High Enables

Integrated Device Technology Inc. acquired logic vendor Quality Semiconductor Inc., based in Santa Clara on 11/3/1998

The QS3126 provides a set of four high-speed CMOS switches connecting inputs to outputs. The low ON resistance of the QS3126 allows inputs to be connected to outputs without propagation delay and without generating additional ground bounce noise. 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. The QS3126operates at -40C to +85C


  • Enhanced N channel FET with no inherent diode to Vcc
  • Pin compatible with the 74’126 function
  • Undershoot clamp diodes on all switch and control inputs
  • 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
  • Available in 16 pin QSOP and 14 pin SOIC packages
