FN6416.0
Low-Voltage, Single and Dual Supply, 8 to
1 Multiplexer
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.
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 0.1nA at
+25°C or 2.5nA 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.
