The HI-201HS is a high-speed analog switch from Intersil. It is manufactured using CMOS technology and has four independently selectable switch channels. It is pin-compatible with the industry standard HI-201 switch. It has a maximum switching time of 50ns, a low ON resistance of 50 ohms, and a wide analog signal range of ±15V. It is suitable for applications that require improved switching performance, especially switching speed, such as high-speed multiplexing, high-frequency analog switching, and sample-and-hold circuits.
The HI-201HS is a monolithic CMOS analog switch featuring four independently selectable SPST switches. It offers fast switching times (30 ns turn‑on, 40 ns turn‑off), low ON resistance (≈50 Ω), and a wide analog voltage range. The device is fabricated with Intersil’s dielectric isolation process and is pin‑compatible with the standard HI‑201.
Designed for high‑speed multiplexing, sample‑and‑hold circuits, and digital filter applications, the HI‑201HS operates from ±15 V supplies and is TTL compatible. Detailed electrical specifications, test circuits, and performance curves are provided to aid designers in integrating the switch into their systems.
