FN6044.4
Low-Voltage, Single Supply, DPDT High
Performance Analog Switch
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.
Table 1 summarizes the performance of this switch.
