The HI-201HS is a high-performance, quad SPST, CMOS Analog Switch featuring very fast switching speeds and low ON resistance. The integrated circuit consists of four independently selectable SPST switches and is pin compatible with the industry standard HI-201 switch. Fabricated using silicon-gate technology and the Intersil Dielectric Isolation process, this TTL compatible device offers improved performance over previously available CMOS analog switches. Featuring maximum switching times of 50ns, low ON resistance of 50Ω maximum, and a wide analog signal range, the HI-201HS is designed for any application where improved switching performance, particularly switching speed, is required.
The HI-201HS analog switch integrates four independently selectable SPST switches in a single monolithic CMOS package. It offers very fast switching speeds (as low as 50 ns) and a low ON resistance of 50 Ω, making it suitable for high‑frequency multiplexing, sample‑and‑hold circuits, and other fast‑switching applications.
The device operates from a ±15 V supply, supports a wide analog input range (±2 V), and includes features such as low charge injection (10 pC) and TTL‑compatible logic inputs. Detailed electrical specifications, absolute maximum ratings, and typical performance curves are provided for design reference.
