HC4P5504BR1862

Telecom Overview

The HC4P5504BR1862 is a high-reliability hex inverter manufactured by Harris Corporation. It belongs to the M54HCxxx series of CMOS logic functions designed for aerospace and harsh environment applications. The device features radiation hardness with a total ionizing dose tolerance of 50 krad(Si) and immunity to single event latch-up up to 125 MeV.cm²/mg. It operates within a supply voltage range of 2 V to 6 V and supports an operating temperature range from -55 °C to +125 °C. The component is housed in a ceramic hermetic package and holds ESCC qualification, ensuring suitability for space missions.

Telecom Feature Summary

• Radiation hardened design suitable for space and high-radiation environments
• High single event latch-up (SEL) immunity
• ESCC qualified for military and aerospace standards
• Ceramic hermetic packaging for environmental protection

Telecom Applications

• Spacecraft onboard computer systems
• Avionics signal processing circuits
• Harsh environment data acquisition systems

Telecom Procurement Notes

Verify the specific ESCC part number against the official European Space Components Coordination database to confirm compliance with MIL-STD-883 requirements. Ensure the supplier provides traceable documentation for the ceramic hermetic seal integrity and radiation test reports. Confirm that the delivered units match the exact M54HC series designation to guarantee functional compatibility with existing circuit designs.

Telecom Selection Notes

Select this component when radiation tolerance and long-term reliability are critical factors. The wide operating temperature range makes it suitable for uncontrolled thermal environments. Verify that the 2 V to 6 V supply voltage aligns with the system power architecture. Consider the ceramic package size and pinout compatibility during PCB layout planning to ensure proper integration into the target assembly.

Telecom Part Context

This part is a member of the M54HC/HCT family produced by Harris Corporation, now part of L3Harris Technologies. The series was specifically engineered to meet the stringent demands of the aerospace industry. These components serve as fundamental building blocks for digital logic in satellite and defense electronics where standard commercial parts would fail due to radiation exposure or extreme conditions.

Telecom Replacement Considerations

Direct replacements must be sourced from manufacturers offering ESCC-qualified M54HC series inverters in ceramic packages. Verify equivalent radiation hardness levels and SEL immunity ratings before substitution. Cross-reference pinouts and electrical characteristics to ensure functional parity without modifying the host circuit board.
