High-Speed CMOS 10-Bit Bus Switch

The QS3384 provides a set of ten high-speed CMOS, TTL-compatible bus switches. The low ON resistance of QS3384 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce. Two banks of 5 switches are controlled by independent Bus Enable (BE) signals. The QS3384 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 added ground bounce
  • Undershoot clamp diodes on all switch and control inputs
  • Two enables control five bits each
  • Available in 24 pin QSOP and TSSOP packages
