The Intersil ISL43410 is a precision, bidirectional, analog switch configured as a double pole/double throw (DPDT) switch. The ISL43410 is designed to operate from a single +2V to +12V supply. It is equipped with an inhibit pin to simultaneously open all signal paths. ON-resistance is 115Ω with a +5V supply, 45Ω with a +12V supply, and 190Ω with a +3V supply. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 3nA at +25°C or 5nA at +85°C. All digital inputs have 0. 8V to 2. 4V logic thresholds ensuring TTL/CMOS logic compatibility when using a single +5V supply. Some of the smallest packages are available, alleviating board space limitations, and making Intersil's newest line of low-voltage switches an ideal solution. The ISL43410 is a DPDT, which is perfect for use in 2-to-1 multiplexer applications.
