简介

The QS34XVH245 HotSwitch is a high bandwidth 32-bit bus switch with very low ON resistance, resulting in under 250ps propagation delay through the switch. 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 near-zero propagation delay, high OFF impedance, and over-voltage tolerance makes the QS34XVH245 ideal for high performance communications applications. The QS34XVH245 operates from -40C to +85C.
