Linear Technology LTC1391 Manuals

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-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 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.

The LTC1391 is a high performance CMOS 8-channel analog multiplexer with a cascading serial interface, allowing multiple LTC1391s to be connected together to increase the number of MUX channels using a single digital port.
