The Intersil ISL43L840 device is a precision, bidirectional,
analog switches configured as a dual 4-channel
multiplexer/demultiplexer, designed to operate from a single
+1.6V to +3.6V supply.
ON resistance is 0.5Ω with a +3V supply and 0.62Ω with a
single +1.8V supply. Each switch can handle rail to rail
analog signals. The off-leakage current is only 4nA max at
+25°C and 30nA max at +85°C with a +3.3V supply.
All digital inputs are 1.8V logic-compatible when using a
single +3V supply.
The ISL43L840 is a dual 4 to 1 multiplexer device that is
offered in a 16 Ld TSSOP and 16 Ld 3x3 QFN packages.
