The QS3VH2861 HotSwitch is a high bandwidth bus switch with 10-bit flow-though pin out. The QS3VH2861, with 25 ohm ON resistance and 1.35ns propagation delay, is ideal for line matching and low noise environments. The combination of small propagation delay, high OFF impedance, and over-voltage tolerance makes the QS3VH2861 ideal for high performance communications applications. The QS3VH2861 operates from -40C to +85C.
