The Intersil ISL84581 device contains precision,
bidirectional, analog switches configured as an 8-to-1
multiplexer/demultiplexer. It was designed to operate from a
single +2V to +12V single supply or from dual ±2V to ±6V
supplies. The device has an inhibit pin to simultaneously
open all signal paths.
The ISL84581 has an ON-resistance of 39Ω with a dual ±5V
supply and 125Ω with a single +3.3V supply. Each switch
can handle rail-to-rail analog signals. The off-leakage current
is only 0.02nA at +25°C or 0.2nA at +85°C.
All digital inputs have 0.8V to 2.4V logic thresholds, ensuring
TTL/CMOS logic compatibility when using a single 3.3V or
+5V supply or dual ±5V supplies.
The ISL84581 is a single 8-to-1 multiplexer device. Table 1
summarizes the performance of the part.
