描述

The QS3VH244 HotSwitch is a high bandwidth, 8-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 the LVTTL-compatible xG signal for bidirectional data flow with no added delay or ground bounce. The combination of near-zero propagation delay, high OFF impedence, and over-voltage tolerance makes the QS3VH244 ideal for high performance communications applications. The QS3VH244 operates from -40C to +85C.
