Overview
The HI4-5049/883 is a high-reliability analog switch manufactured by Harris Corporation, designed for demanding military and aerospace applications. It features two independent single-pole double-throw (SPDT) circuits within a single package. The device operates with a low on-resistance of 45 Ohms and supports a wide dual power supply range from ±10 V to ±36 V. Packaged in a 20-lead ceramic leaded chip carrier (CLCC) measuring 8.89x8.89 mm, it ensures robust performance across an extended temperature range of -55°C to +125°C.
Feature Summary
- Dual SPDT configuration providing two independent signal switching channels
- Low on-resistance characteristic of 45 Ohms for minimal signal loss
- Wide operating voltage range supporting ±10 V to ±36 V supplies
- Extended industrial temperature rating suitable for harsh environments
Applications
- Military communication systems requiring high reliability
- Aerospace instrumentation and control circuits
- Test and measurement equipment signal routing
- Harsh environment data acquisition systems
Procurement Notes
Verify the specific suffix designation against official Harris datasheets to confirm exact electrical tolerances and thermal specifications. Ensure compatibility with existing board layouts regarding the 20-CLCC footprint dimensions. Confirm that the procurement source provides traceability documentation required for defense or aerospace contracts. Check RoHS compliance status as this component may fall under restricted substance regulations depending on the manufacturing date.
Selection Notes
Select this component when dual-channel switching is required in space-constrained designs utilizing the CLCC package. Consider the 45 Ohm on-resistance impact on signal integrity for high-frequency applications. Evaluate the ±10 V to ±36 V supply requirements against available system power rails. Verify that the -55°C to +125°C operating range meets the environmental conditions of the target deployment scenario.
Part Context
This part belongs to the Harris Corporation HI series of high-reliability analog switches. These components are specifically processed to meet stringent military data sheet requirements. The series offers various configurations including multiplexers and switches in ceramic packages designed for long-term stability and radiation hardness in critical electronic systems.
Replacement Considerations
Consult official Harris cross-reference documents for direct equivalents. Verify pinout compatibility and package dimensions before substituting. Ensure replacement parts meet the same MIL-spec processing requirements.
