description

The LTC ® 1391 is a high-performance CMOS 8-1 analog multiplexer. It features a serial digital interface that allows the LTC1391s to be daisy-chained together, increasing the number of MUX channels using a single digital port.

LTC1391 features a typical R of 45 ohms, a typical leakage switch of 50pA and guaranteed breakthrough beforemake operation. Charge injection ± 10PC max. All digital inputs are compatible with TTL and CMOS when operating from single or dual supplies. The input can withstand a fault current of 100 milliamps.

LTC1391 available in 16-pin PDIP, SSOP, and narrow SO packages. 2 applications of serial data transmission requirements LTC1390 data sheets.
