The LTC1390 is a high performance CMOS 8-to-1 analog multiplexer. It features a 3-wire digital interface with a bidirectional data retransmission feature, allowing it to be wired in series with a serial A/D converter while using only one serial port. The interface also allows several LTC1390s to be wired in series or parallel, increasing the number of MUX channels available using only a single digital port. All the above features are also valid when LTC1390 operates as a demultiplexer such as with a D/A converter.
The LTC1390 features a typical RON of 45Ω, typical switch leakage of 50pA, and guaranteed break-before-make operation. Charge injection is ±10pC maximum. All digital inputs are TTL and CMOS compatible when operated from single or dual supplies. The inputs can withstand 100mA fault currents.
The LTC1390 is available in 16-pin PDIP and narrow SO packages.
