The Maxim HI-201 is a monolithic CMOS quad single‑pole‑single‑throw (SPST) analog switch designed as a plug‑in upgrade for the Harris HI‑201. It eliminates the need for a VREF supply and consumes only 4 mW typical power, making it suitable for portable applications. The device operates from a single supply of +4.5 V to +18 V or from dual supplies of +5 V to +30 V, with fast switching times (ton ≈ 260 ns, toff ≈ 100 ns) and a typical on‑resistance of 452 Ω.
The datasheet provides absolute maximum ratings, electrical characteristics, pin configurations, and protection recommendations. It also includes typical operating curves for on‑resistance versus analog‑signal level, leakage currents, and temperature effects. Ordering information and package outlines are listed for various DIP, SO, and CERDIP options.
