M38510/30901BEA

Overview

The M38510/30901BEA is a military-grade 8-line-to-1-line data selector and multiplexer manufactured by Texas Instruments. It belongs to the SN54LS151 series, utilizing Low-Power Schottky TTL logic technology. The component is housed in a 16-pin Ceramic Dual In-Line Package (CDIP). It operates within an extended temperature range of -55°C to +125°C and is qualified under MIL-M-38510 standards for defense applications.

Feature Summary

• Provides high-speed selection of one of eight digital input channels to a single output line
• Features active-low enable functionality for precise control over data routing operations
• Constructed with Low-Power Schottky technology to optimize power consumption relative to switching speed

Applications

• Military communication systems requiring reliable signal routing
• Defense avionics data bus management
• High-reliability industrial control logic circuits

Procurement Notes

Verify that the specific order includes the correct suffix 'BEA' to ensure the CDIP package variant. Confirm that the procurement channel provides traceability documentation required for MIL-M-38510 components. Ensure handling procedures account for the ceramic package construction during installation.

Selection Notes

Select this component when an 8-channel multiplexer is required for harsh environments. The LS family offers a balance of speed and power dissipation suitable for battery-operated or thermally constrained military platforms. Verify voltage compatibility with existing TTL logic levels before integration into the circuit design.

Part Context

This part is a specialized military version of the commercial SN54LS151. While functionally identical to the standard catalog device, it undergoes rigorous screening and testing protocols mandated by Department of Defense specifications. It ensures long-term reliability and performance consistency in critical aerospace and defense hardware deployments.

Replacement Considerations

Direct functional equivalents include the SNJ54LS151J and SNJ54LS151FK. Commercial alternatives such as the SN74LS151 are not suitable replacements due to restricted operating temperature ranges and lack of military qualification.
