Overview
Description
The HI-303/883 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-303/883 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 4.0V.
The device is pin-for-pin compatible with the industry standard Siliconix DG303 and is available in a 14-pin Ceramic DIP. The HI-303/883 operates over the -55 °C to +125 °C temperature range.
