QS3VH16800 - Block Diagram
Description
The QS3VH16800 HotSwitch is a 20-bit high bandwidth 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 Output Enable signal for bidirectional data flow with no added delay or ground bounce. It can be used as two 10-bit bus switches or one 20-bit bus switch. The combination of near-zero propagation delay, high OFF impedance, and overvoltage tolerance makes the QS3VH16800 ideal for high-performance communications applications. The QS3VH16800 operates from -40 °C to +85 °C.
Applications
- Hot-swapping
- 10/100 Base-T, Ethernet LAN switch
- Low distortion analog switch
- Replaces mechanical relay
- ATM 25/155 switching
