1391 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, increas-
ing the number of MUX channels available using a single
digital port.
The LTC1391 features a typical R
ON
of 45W , 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 oper-
ated from single or dual supplies. The inputs can with-
stand 100mA fault current.
The LTC1391 is available in 16-pin PDIP,
