The LTC1390CS is a high-performance CMOS 8-to-1 analog multiplexer designed for efficient analog signal routing. It features a 3-wire serial digital interface with a bidirectional data retransmission capability, allowing it to be connected in series with a serial A/D converter while using only one serial port. This interface also enables multiple LTC1390 devices to be wired in series or parallel, expanding the number of available multiplexer channels without increasing the number of required digital ports. The device operates over a wide supply voltage range and includes features such as low on-resistance, low leakage currents, and guaranteed break-before-make operation, making it suitable for applications in data acquisition systems, communication systems, and general signal multiplexing.
