Overview

The QS34XVH2245 high-bandwidth, 32-bit bus switch with 25Ω resistance and 1.35ns propagation delay is ideal for line matching and low noise environments. The switches can be turned ON under the control of individual LVTTL-compatible Output Enable (OEx) signals for bidirectional data flow with no added delay or ground bounce. The combination of small propagation delay, high OFF impedance, and overvoltage tolerance makes the QS34XVH2245 ideal for high-performance communications applications. The QS34XVH2245 operates from -40 °C to +85 °C.
