Overview
Description
The QS34XVH2245 is a high bandwidth, 32-bit bus switch. The QS34XVH2245 with 25 ohm 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 over-voltage tolerance makes the QS34XVH2245 ideal for high performance communications applications. The QS34XVH2245 operates from -40C to +85C.
