HI1-0300-8

Analog Switches, Multiplexers, Demultiplexers Overview

The HI1-0300-8 is a monolithic CMOS analog switch manufactured by Harris Corporation. It features break-before-make switching action and low, nearly constant ON resistance across the full analog signal range. The device operates with TTL-compatible logic levels, requiring an input less than 0.8V for a logic '0' and greater than 4V for a logic '1'. It is designed for applications requiring low power dissipation and high reliability in harsh environments.
