The ISL84541–ISL84544 devices are precision, dual analog switches designed to operate from a single +2.7V to +12V supply. They are suitable for battery-powered equipment that benefits from low power consumption (5µW), low leakage currents (100pA max), and fast switching speeds (tON = 35ns, tOFF = 25ns). These devices can be used to add additional functionality while reducing ASIC design risk. The small packages available alleviate board space limitations, making them an ideal solution. The ISL84541/ISL84542/ISL84543 are dual single-pole/single-throw (SPST) devices. The ISL84541 has two normally open (NO) switches; the ISL84542 has two normally closed (NC) switches; the ISL84543 has one NO and one NC switch and can be used as an SPDT. The ISL84544 is a committed SPDT, which is perfect for use in 2-to-1 multiplexer applications. Table 1 summarizes the performance of this family. For higher performance, pin compatible versions, see the ISL43120 - 22 and ISL43210 datasheet. Related Literature Technical Brief TB363 “Guidelines for Handling and Processing Moisture Sensitive S
The ISL84541‑ISL84544 family are low‑voltage, single‑supply dual analog switches designed for battery‑powered equipment. They operate from +2.7 V to +12 V, consume as little as 5 nW, and feature fast switching (ton ≈ 35 ns, torr ≈ 25 ns). Variants provide SPST or SPDT configurations and are offered in PDIP, SOIC, SOT‑23 and MSOP packages.
The datasheet includes electrical characteristics (on‑resistance, leakage, ESD rating), absolute maximum ratings, test circuits, and ordering information. Applications listed include mobile phones, handheld devices, test equipment and audio/video switching.
