Description

The HI-303 switch is a monolithic device fabricated using CMOS technology and the Intersil 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. (See pinouts for switch conditions with a logic '1' input.)

Applications

• Sample and Hold (i.e., Low Leakage Switching)
• Op Amp Gain Switching (i.e., Low On Resistance)
• Portable, Battery Operated Circuits
• Low Level Switching Circuits
• Dual or Single Supply Systems
