ISL84525 Low-Voltage, Single Supply, 4 to 1 Multiplexer and DPDT Analog Switches

The Intersil ISL84524 and ISL84525 devices are precision, bidirectional, analog switches configured as a 4 channel multiplexer/demultiplexer (ISL84524) and a double pole/ double throw (DPDT) switch (ISL84525) designed to operate from a single +2V to +12V supply. Both have an inhibit pin to simultaneously open all signal paths.

ON resistance is 200Ω with a +5V supply and 500Ω with a +3V supply. Each switch can handle rail to rail analog signals. The off-leakage current is only 1nA at +25oC or 25nA at +85oC.

All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS logic compatibility when using a single +5V supply.

The ISL84524 is a 4 to 1 multiplexer device. The ISL84525 is a DPDT, which is perfect for use in 2-to-1 multiplexer applications.
