Overview
The HI1-0304-2 is a dual-channel analog switch integrated circuit manufactured by Harris Corporation. It features two single-pole single-throw (SPST) switches with a nominal on-resistance of 50 Ohms. The device is housed in a 14-lead ceramic dual in-line package (CERDIP). It supports an operating temperature range from -55°C to 125°C, suitable for industrial and military environments.
Feature Summary
- Dual SPST analog switching configuration
- 50 Ohm nominal on-resistance
- High-temperature ceramic DIP packaging
Applications
- Signal routing in test and measurement equipment
- Data acquisition systems
- Industrial control interfaces
Procurement Notes
Verify the manufacturer source is Harris Corporation or authorized successor entities like L3Harris. Confirm the package type is 14-CERDIP rather than plastic DIP. Check datasheet revisions for handling procedures regarding ceramic packages. Ensure specifications match the -55 to 125°C range.
Selection Notes
Select this component when dual isolated signal paths are required with moderate on-resistance. The ceramic package provides superior thermal stability compared to plastic variants. Consider pin compatibility if replacing older Harris designs. Verify voltage ratings against application requirements.
Part Context
This part belongs to the HI1 series of analog switches from Harris Corporation. These components were widely used in defense and aerospace applications before corporate restructuring. The HI1-0304 variant specifically offers dual channels, distinguishing it from single-channel or multiplexer versions in the same family.
Replacement Considerations
Direct substitutes may include HI1-0304-8 or HI1-0304-5 depending on temperature grade requirements. Verify pinout compatibility before substitution. Cross-reference with current L3Harris product lines for availability.
