HI1-0518/883

Overview

The HI1-0518/883 is a military-grade analog integrated circuit manufactured by Harris Corporation, classified as a high-speed comparator. It features a single channel of amplification within a hermetically sealed 8-pin ceramic flatpack package (CERDIP). The device is designed for operation across the full military temperature range of -55°C to +125°C and requires dual power supplies typically ranging from ±5V to ±15V. Key electrical specifications include a maximum input offset voltage of 2.0 mV and a typical slew rate of 100 V/µs, enabling rapid signal transitions. The component supports a wide common-mode input voltage range and offers high differential gain, making it suitable for precision applications requiring fast response times in harsh environments.

Procurement Notes

Verify the manufacturer date code and lot traceability upon receipt to ensure compliance with project requirements. Confirm that the component matches the specific subgrade designation indicated on the datasheet. Inspect the ceramic package for physical integrity, ensuring no cracks or pin damage are present. Check for proper marking legibility and authenticity labels. Ensure storage conditions meet moisture sensitivity level requirements before soldering.

Selection Notes

Select this component when a high-speed, low-offset comparator is required for military or industrial applications. Consider the 8-pin CERDIP package constraints for PCB layout and thermal management. Evaluate the supply voltage requirements against the system's available rails. Compare the slew rate and propagation delay specifications against the target application's timing constraints to ensure adequate performance margins.

Part Context

This part belongs to the Harris Corporation family of high-performance linear integrated circuits designed for defense and aerospace markets. The '/883' suffix indicates compliance with MIL-PRF-38534 standards for hybrid microcircuits. Harris Corporation, now part of Renesas Electronics, has a long history of producing reliable semiconductor components for critical systems. This specific model represents a legacy high-speed comparator design maintained for existing military hardware support.

Replacement Considerations

Direct replacements must match the MIL-PRF-38534 qualification and pinout compatibility. Verify that any substitute component meets the same electrical limits for offset voltage and slew rate. Ensure the replacement package is mechanically compatible with the existing footprint. Consult official cross-reference lists for authorized equivalents.
