Overview
Description
The QS3VH125 is a high-bandwidth, quad bus switch. The QS3VH125 has 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 active low Output Enable signals for bidirectional data flow with no added delay or ground bounce. The combination of near-zero propagation delay, high OFF impedance, and overvoltage tolerance makes the QS3VH125 ideal for high-performance communications applications. The QS3VH125 operates from -40 °C to +85 °C.
