描述
The QS32XVH2245 HotSwitch is a high bandwidth, 16-bit bus switch that is ideal for line matching and low noise environments. The switches can be turned ON under the control of the LVTTL-compatible Output Enable (OEx) signal 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 QS32XVH2245 ideal for hot-swapping applications. The QS32XVH2245 operates from -40 °C to +85 °C.
