HD1-15530B3976

Overview

The HD1-15530B3976 is a CMOS Manchester encoder/decoder manufactured by Harris Corporation. It serves as an extended-temperature MIL-STD-1553 component designed for military applications. The device implements the Manchester encoding and decoding functions required for MIL-STD-1553 bus communication systems, ensuring reliable data transmission in demanding operational environments.

Feature Summary

• Implements Manchester encoding and decoding protocols
• Designed for extended-temperature military operations
• Complies with MIL-STD-1553 standards

Applications

• Military communication systems
• MIL-STD-1553 bus interfaces
• Avionics data buses

Procurement Notes

Verify the manufacturer designation, as Harris Corporation assets were acquired by Microchip Technology. Confirm that the specific suffix B3976 corresponds to the intended package and temperature grade. Ensure compatibility with existing MIL-STD-1553 system architectures before procurement.

Selection Notes

Select this component when a dedicated CMOS Manchester encoder/decoder is required for MIL-STD-1553 compliance. It is suitable for designs necessitating extended temperature ranges typical of military hardware. Evaluate pinout compatibility with existing circuit boards if replacing legacy parts.

Part Context

This part belongs to the HI-15530 series of MIL-STD-1553 interface components. The series provides essential physical layer signaling functions for military data buses. Harris Corporation originally developed these components, which are now managed under Microchip's portfolio following corporate acquisitions.

Replacement Considerations

Check for direct substitutes within the HI-15530 family or equivalent MIL-STD-1553 encoders from other qualified vendors. Verify that any replacement maintains the same CMOS logic levels and MIL-STD-1553 timing specifications.
