DM54LS375DM-MIL

Latches Overview

The DM54LS375DM-MIL is a military-grade 4-bit bistable latch manufactured by National Semiconductor. It belongs to the 54LS series, utilizing Low-power Schottky TTL logic technology. The device features eight D-type inputs and corresponding Q outputs, designed for high-reliability digital data storage applications in harsh environments.

Latches Feature Summary

• Military-grade construction ensuring reliability in extreme conditions
• Low-power Schottky TTL architecture for efficient operation
• Four-bit parallel data latching capability with direct input access

Latches Applications

• Data synchronization in military communication systems
• Debouncing mechanical switches in ruggedized equipment
• Constructing registers for temporary data storage in aerospace electronics

Latches Procurement Notes

Verify the manufacturer origin carefully, as National Semiconductor's logic assets were acquired by Texas Instruments. Confirm that the specific suffix indicates genuine military qualification standards rather than commercial equivalents. Ensure documentation matches the exact part number to avoid receiving non-mil-spec variants.

Latches Selection Notes

Select this component when strict environmental tolerance and long-term stability are required for digital latch functions. The 54-series designation implies wider temperature ranges compared to standard 74-series parts. Consider pin compatibility if replacing older designs while maintaining military compliance requirements.

Latches Part Context

This part is part of the broader 54LS375 family of 4-bit latches. The 'MIL' suffix specifically denotes military qualification, distinguishing it from commercial or industrial grade versions. It serves as a fundamental building block for sequential logic circuits requiring robust performance under stress.

Latches Replacement Considerations

Direct substitutes include other 54LS375 variants with military ratings. Verify pinout compatibility before substitution. Commercial equivalents like the SN54LS375 lack the necessary environmental qualifications for this specific application.
