Overview

The QS32XVH384 HotSwitch is a high bandwidth, 20-bit bus switch with very low ON resistance, resulting in under 250ps propagation delay through the switch. Four banks of five switches are controlled by independent (xOE), LVTTL compatible signals for bidirectional data flow with no added delay or ground bounce. The combination of near-zero propagation delay, high OFF impedance, and over-voltage tolerance makes the QS32XVH384 ideal for high performance communications applications. The QS32XVH384 operates from -40C to +85C.
