The HI-201HS is a monolithic CMOS quad single‑pole‑single‑throw (SPST) analog switch offering fast switching (30 ns turn‑on) and low on‑resistance (≤50 Ω). It operates from dual supplies ranging from +5 V to +20 V and is pin‑compatible with the industry‑standard DG201A.
Key specifications include a 44 V maximum supply rating, 500 Ω maximum on‑resistance, various DIP, SO and LCC package options, and an operating temperature range from –40 °C to +125 °C. The device is suitable for automatic test equipment, heads‑up displays, communication systems, and sample‑and‑hold circuits.
