HI-8197PSIF

Analog Switches, Multiplexers, Demultiplexers Overview

The HI-8197PSIF is a quad single-pole single-throw (SPST) analog switch manufactured by Holt Integrated Circuits Inc. It integrates four independent switches within a 16-pin SOIC package, providing a channel resistance of 31 ohms. The device operates with a supply voltage range supporting standard logic levels and features an open-circuit state when power is removed, ensuring signal isolation during shutdown. Designed for industrial applications, it functions reliably across a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'I' indicates RoHS compliance status as sources vary; confirm the manufacturer lead time of six weeks against current production schedules. Ensure the 16-SOIC footprint matches the target PCB design constraints before finalizing orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad-channel configuration is required for cost-effective signal switching. The 31-ohm on-resistance suits low-voltage signal paths where moderate precision is acceptable. Consider the exposed pad or standard SOIC variant depending on thermal management needs.
