8408901EA

Overview

The Texas Instruments 8408901EA is a quadruple D-type flip-flop featuring independent clear inputs. It is housed in a 16-lead Ceramic Dual In-Line Package (CDIP). The device operates within an extended military temperature range of -55°C to +125°C. This component is designed for high-reliability digital logic applications requiring precise data storage and synchronization.

Feature Summary

• Contains four independent D-type flip-flops with dedicated clear functionality
• Constructed in a hermetically sealed ceramic dual in-line package for environmental protection
• Rated for extended military-grade operating temperature conditions

Applications

• Military aerospace digital systems
• High-reliability industrial control logic
• Harsh environment data storage circuits

Procurement Notes

Verify the specific suffix 'EA' against the manufacturer's current datasheet to confirm pinout compatibility and material specifications. Ensure the supplier provides traceability documentation suitable for military or aerospace procurement standards, as this package type indicates specialized manufacturing requirements.

Selection Notes

Select this component when hermetic sealing and wide temperature tolerance are mandatory. The CDIP package offers superior durability compared to plastic variants. Confirm that the circuit design supports the specific voltage levels and timing characteristics defined in the official SN54HC175 family documentation.

Part Context

This part belongs to the SN54 series, which denotes military-grade performance standards. The 'HC' designation indicates High-Speed CMOS technology, offering lower power consumption than older TTL equivalents while maintaining compatible logic levels. The 8408901EA represents the specific packaging and variant configuration within this logical family.

Replacement Considerations

Direct replacements must match the SN54HC175 functional specification and 16-CDIP physical footprint. Verify that substitute parts maintain the same extended temperature rating and hermetic seal properties required for the original application environment.
