QS3306A

High-Speed CMOS Dual Bus Switch with IndiviDual Active Low Enables

The QS3306A provides a set of two high-speed low resistance (3 ohm typical) CMOS switches connecting inputs to outputs without propagation delay and without generating additional ground bounce noise. Individual enables (OE) are used to turn on the switches. The QS3306A 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 QS3306A can also be used for analog switching applications such as video. The QS3306A operates at -40C to +85C.

Features

  • Enhanced N channel FET with no inherent diode to Vcc
  • Very low ON resistance (5 ohm typical)
  • Zero propagation delay, zero added ground bounce
  • Fast turn-on/turn-off time
  • Undershoot clamp diodes on all switch and control inputs
  • Available in 8 pin SOIC package
