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.
Feature Summary
- Monolithic CMOS construction using dielectric isolation process
- Break-before-make switching action prevents signal shorting
- Low and nearly constant ON resistance over full analog signal range
- TTL compatible logic interface
Applications
- Sample and hold circuits
- Op amp gain switching
- Portable battery operated circuits
- Low level switching circuits
Procurement Notes
Verify component authenticity through authorized distributors or certified secondary market suppliers. Confirm manufacturing date codes and lot traceability to ensure compliance with original specifications. Inspect for physical damage and verify pin integrity before integration into sensitive analog systems.
Selection Notes
Select this component when break-before-make timing is critical to prevent signal overlap. Ensure supply voltages remain within specified limits to maintain ON resistance characteristics. Consider thermal management requirements as power dissipation increases with load current and duty cycle.
Part Context
This part belongs to the HI-303 family of CMOS analog switches. The series includes variants with different package options and pin configurations. These components are widely used in industrial and military applications due to their robust construction and reliable performance under extreme temperature conditions.
Replacement Considerations
Direct replacements include other HI-303 series variants from Harris or equivalent CMOS analog switches from manufacturers like Analog Devices or Maxim Integrated. Verify pin compatibility and electrical parameters such as ON resistance and leakage current before substitution.
