HI-8197PCIF

Analog Switches, Multiplexers, Demultiplexers Overview

The HI-8197PCIF is a quad single-pole single-throw (SPST) analog switch manufactured by Holt Integrated Circuits Inc. It features four independent channels within a 16-pin Chip Scale Package (CSP). The device supports both normally open and normally closed configurations with a maximum on-resistance of 31 ohms. It operates on a single power supply ranging from 3V to 5.5V and functions reliably across an industrial temperature range of -40°C to +85°C.
