The LTC1391 is a high performance CMOS 8-to-1 analog multiplexer. It features a serial digital interface that allows several LTC1391s to be daisy-chained together, increasing the number of MUX channels available using a single digital port.
The LTC1391 features a typical RON of 45Ω, a typical switch leakage of 50pA and guaranteed break-beforemake 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 current.
The LTC1391 is available in 16-pin PDIP, SSOP and narrow SO packages. For applications requiring 2-way serial data transmission, see the LTC1390 data sheet.
Applications
- Data Acquisition Systems
- Communication Systems
- Signal Multiplexing/Demultiplexing
