Overview

The HI-303 switch is a monolithic device fabricated using CMOS technology and our dielectric isolation process. This switch features break-before-make switching, low and nearly constant ON resistance over the full analog signal range, and low power dissipation.

The HI-303 is TTL compatible and has a logic "0" condition with an input less than 0.8V and a logic "1" condition with an input greater than 4V.

  1. Can HI-303 operate with a single +5V supply voltage?

    Question: Can HI-303 operate with a single +5V supply voltage instead of +/-15V?   Answer: No, the HI-303 family cannot be run on a +5V only system. If you look at the data sheet there is a Figure which shows that the switching times increase dramatically as you ...
