High-Speed CMOS QuickSwitch 32-Bit Multiwidth Bus Switch

概览

The QS34X2245 provides a set of 32 high-speed CMOS-compatible bus switches in a flow-through pinout. The low ON-resistance of the QS34X2245 allows inputs to be connected to outputs without adding propagation delay and without generating additional ground bounce noise. Internal 25Ω resistors reduce reflection noise in high-speed applications. This device is ideally suited for 32/64-bit applications where board space is at a premium. The QS34X2245 operates at -40 °C to +85 °C.
