QuickSwitch Products High-Speed CMOS 20-Bit Bus Switch

The QS32X384 provides a set of twenty high-speed CMOS TTLcompatible bus switches. The low ON resistance of the QS32X384 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. Four Bus Enable signals are provided, one for each of five bits of the 20-bit bus. The QS32X384 is ideal for switching wide digital buses, as well as hotplug buffering, and 5V to 3V conversion. The QS32X384 operates at -40C to +85C.

Features

  • Enhanced N channel FET with no inherent diode to VCC
  • 5 ohm bidirectional switches connect inputs to outputs
  • Zero propagation delay
  • Zero ground bounce
  • Undershoot clamp diodes on all switch and control pins
  • Four enables control five bits each
  • TTL-compatible input and output levels
  • Available in 48-pin QVSOP package
