QuickSwitch Products 3.3V 8-Bit Bus Switch for Hot Swap Applications
Jump to Page Section:
Overview
Description
The QS3VH245 HotSwitch 8-bit bus switch is a 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. The combination of near-zero propagation delay, high OFF impedance, and over-voltage tolerance makes the QS3VH245 ideal forhigh performance communications applications. The QS3VH245 operates from -40C to +85C.
