SN54SC8T373MPWTSEP

Latches Overview

The SN54SC8T373MPWTSEP is a radiation-tolerant octal transparent D-type latch with three-state outputs, designed for space applications. It features reduced input voltage thresholds to support up-translation capabilities. The device operates within a military temperature range of -55°C to +125°C and utilizes a 20-pin ceramic flatpack (MPW) package. It belongs to the SCASE63 family, ensuring reliability in high-radiation environments.

Latches Feature Summary

• Radiation tolerant design suitable for space missions
• Octal transparent D-type latch architecture with three-state outputs

• Satellite telemetry processing

Latches Procurement Notes

Verify the complete part number including the SEP suffix to ensure radiation tolerance specifications are met. Confirm the MPW package variant matches the required footprint. Check for specific lot traceability requirements if mandated by the program. Ensure environmental testing standards align with project constraints before finalizing procurement.

Latches Selection Notes

Select this component when radiation hardness is critical for system reliability. The reduced input thresholds make it suitable for level-shifting applications in mixed-voltage environments. Consider the ceramic package for superior thermal and mechanical stability compared to plastic alternatives in harsh operating conditions.

Latches Part Context

This device is part of Texas Instruments' SCASE63 family of radiation-tolerant logic components. It shares functional similarities with standard SN54SC373 devices but includes enhanced hardening against total ionizing dose and single-event effects. It serves as a specialized solution for aerospace and defense electronics requiring robust performance.

Latches Replacement Considerations

SN54SC8T373MPWTSEP.A is listed as a related variant. Verify pinout compatibility and radiation specs before substitution. Standard commercial SN54SC373 parts lack radiation tolerance and are not direct replacements for space applications.
