100371FM-MLS

Overview

The 100371FM-MLS is a low-power triple 4-input multiplexer from National Semiconductor's 100K series. It features three independent functions, each with four line inputs and one output, utilizing complementary outputs. The device operates using ECL logic levels and is housed in a 24-pin Cerquad (CFLATPACK) package. It includes enable functionality for controlled signal routing.

Feature Summary

• Triple 4-input multiplexing capability
• ECL logic family operation
• Complementary output configuration
• Enable control functionality

Applications

• Signal routing in high-speed digital systems
• Data selection in ECL-based circuits
• Multiplexing applications requiring low power consumption

Procurement Notes

Verify the manufacturer origin as National Semiconductor, now part of Texas Instruments, due to corporate acquisitions. Confirm the package type is 24-Cerquad or CFLATPACK. Ensure the suffix MLS matches the specific variant requirements. Check for obsolescence status given the age of the 100K series. Validate authenticity through authorized distributors or certified surplus suppliers.

Selection Notes

Select this component when a triple 4-to-1 multiplexer with ECL compatibility is required. Consider the 24-pin Cerquad package constraints for PCB layout. Evaluate power dissipation needs against the low-power specification. Ensure system voltage levels align with ECL standards. Verify that the enable feature meets control logic requirements.

Part Context

Part of National Semiconductor's 100K series, designed for high-speed ECL applications. The 100K series offers low power consumption compared to standard ECL devices. This specific model provides multiple independent channels within a single package, reducing board space and interconnect complexity in dense digital designs.

Replacement Considerations

Check for direct pin-compatible substitutes within the 100K series or updated ECL multiplexers from Texas Instruments. Verify electrical parameters such as propagation delay and supply current match original specifications. Ensure package dimensions are compatible with existing footprints.
