The LTC
廬
1390 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 R
ON
of 45鈩? typical switch
leakage of 50pA, and guaranteed break-before-make op-
eration. Charge injection is
鹵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.
