Overview
The HI1-5048-2 is a dual-channel, single-pole single-throw (SPST) analog switch manufactured by Harris Corporation. It utilizes monolithic CMOS technology with dielectric isolation to ensure latch-free operation and low leakage currents. The device features a nominal on-resistance of 25 ohms, which remains constant over the full range of operating signal voltage and current. It supports break-before-make switching and is compatible with TTL and CMOS logic families. The component is housed in a 16-pin ceramic dual in-line package (CERDIP) suitable for harsh environments.
Feature Summary
- Dielectric isolation processing eliminates latch-up issues and reduces substrate leakage.
- On-resistance remains exceptionally constant across the full operating signal voltage range.
- Break-before-make switching action prevents signal shorting during channel transitions.
- Direct interface capability with standard TTL and CMOS logic families without pull-up resistors.
Applications
- Data acquisition systems requiring precise signal routing
- Precision instrumentation circuits
- Demultiplexing applications
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and environmental rating. Ensure that the procurement source provides traceability for military or harsh environment specifications if required by the design. Confirm lead finish and moisture sensitivity levels prior to assembly planning.
Selection Notes
Select this component when dual SPST switching with low, stable on-resistance is required in a ruggedized package. Verify that the supply voltage range aligns with the system's ±15V requirement. Consider the CERDIP package constraints for PCB layout and thermal management compared to plastic alternatives.
Part Context
This part belongs to the HI-504x series of CMOS analog switches from Harris Corporation. The series includes variants such as the HI-5046A, HI-5047A, and HI-5051. These devices share common characteristics like dielectric isolation and TTL/CMOS compatibility but differ in channel count and package options.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the HI-504x family or equivalent dielectric-isolated CMOS switches only after verifying electrical parameter equivalence.
