Overview
The HI1-0509A-5 is a military-grade, differential 4-channel CMOS analog multiplexer featuring active overvoltage protection. Fabricated using 44V dielectrically isolated CMOS technology, it allows analog input levels to significantly exceed power supply rails without device damage or signal path disturbance. The component supports constant 70VP-P input levels with ±15V supplies and sustains digital input faults up to 4V beyond either supply rail. It ensures fail-safe operation during power loss by preventing latch-up and protecting signal sources from short-circuiting through 1kΩ input resistance.
Feature Summary
- Active overvoltage protection maintains signal fidelity under fault conditions that would destroy standard multiplexers
- Dielectrically isolated CMOS construction prevents channel interaction during overvoltage events
- Fail-safe design prevents latch-up and protects signal sources during multiplexer supply loss
Applications
- Systems where analog inputs originate from external equipment
- Circuits involving separately powered circuitry
- Military and aerospace applications requiring high reliability
Procurement Notes
Verify the specific suffix '5' against official Intersil documentation to confirm exact temperature range and qualification status. Ensure compatibility with existing system voltage requirements, as the device supports maximum power supplies of 44V. Confirm package integrity for the CDIP format if applicable to your assembly process.
Selection Notes
Select this component when active overvoltage protection is critical for preserving signal integrity in harsh environments. The HI1-0509A-5 is suitable for differential signal paths requiring isolation between channels during fault conditions. Consider the 44V dielectric isolation capability if operating near high-voltage boundaries.
Part Context
This part belongs to the HI-509A family of analog multiplexers, which includes single-ended and differential variants like the HI-506A, HI-507A, and HI-508A. All devices in this series share the same core fabrication technology and overvoltage protection features, differing primarily in channel count and configuration.
