LTC1380CS#PBF

LTC1380CS#PBF is a CMOS analogue multiplexer with SMBus® compatible digital interfaces. The LTC1380 is a single-ended 8-channel multiplexer. The SMBus digital interface requires only two wires (SCL and SDA). It has four hard-wired SMBus addresses, selectable with two external address pins. This allows four devices, each with a unique SMBus address, to coexist on one system and for four devices to be synchronized with one stop bit. Typical applications include data acquisition systems, process control, laptop computers, signal multiplexing/demultiplexing, and analogue-to-digital conversion systems.
