HI1-0302/883

Analog Switches, Multiplexers, Demultiplexers Overview

The HI1-0302/883 is a dual-channel analog switch manufactured by Harris Corporation. It features two single-pole single-throw (SPST) circuits within a single integrated circuit. The device operates with an on-resistance of 50 Ohms and is housed in a 14-pin CERDIP package, which measures 0.300 inches (7.62mm) in width. This component is classified as an analog switch suitable for signal routing applications.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Integrates two independent SPST analog switching channels
• Provides 50 Ohm on-resistance for signal path control
• Utilizes a 14-pin ceramic dual in-line package (CERDIP)
• Designed for precise analog signal commutation

Analog Switches, Multiplexers, Demultiplexers Applications

• Signal routing in test and measurement equipment
• Analog data acquisition systems
• Communication system signal switching
• Instrumentation front-end multiplexing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix /883 against manufacturer documentation to confirm package variant and environmental compliance status. Note that this component may not comply with RoHS standards. Confirm moisture sensitivity level (MSL 3) handling requirements during storage and assembly to prevent package damage. Ensure compatibility with existing PCB footprint specifications for the 14-CERDIP form factor.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual-channel isolation is required with a standardized 50 Ohm impedance profile. The CERDIP package offers robustness for industrial environments but requires through-hole mounting considerations. Evaluate thermal management needs based on the power dissipation characteristics inherent to the 50 Ohm on-state resistance. Verify voltage ratings against the maximum signal levels present in the target application circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the HI1 series of analog switches from Harris Corporation, now part of Intersil/Renesas. The series focuses on high-performance signal switching solutions. The HI1-0302 variant specifically addresses applications requiring multiple isolated switching paths in a compact ceramic package, distinguishing it from plastic DIP alternatives or higher-density multiplexer variants.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other 14-pin CERDIP dual SPST analog switches with comparable 50 Ohm on-resistance. Verify pinout compatibility and electrical parameters such as leakage current and breakdown voltage before substitution. Cross-reference with Intersil/Renesas updated product lines for equivalent functionality.
