MC100EL31DT

Flip Flops Overview

The MC100EL31DT is a single D-type flip-flop from the onsemi 100LVEL series, designed for high-speed clock distribution and timing applications. It operates with a negative supply voltage ranging from -3V to -3.8V and supports clock frequencies up to 2.9 GHz. The device features positive-edge triggering with set and reset functions, providing complementary outputs in an 8-TSSOP surface-mount package. It is rated for operation between -40°C and 85°C but does not comply with RoHS standards.

Flip Flops Feature Summary

• Supports high-frequency clock signals up to 2.9 GHz
• Integrates set and reset control functions for precise timing management
• Provides differential output signals for noise immunity

Flip Flops Applications

• High-speed clock distribution networks
• Timing synchronization circuits
• Data sampling and storage systems

Flip Flops Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking authorized distributors or third-party suppliers for remaining stock. Buyers must confirm the non-RoHS status and ensure compatibility with existing -3V to -3.8V power supplies before procurement.

Flip Flops Selection Notes

Select this part when a single D-flip-flop with set/reset capabilities is required for ECL-level logic at frequencies near 3 GHz. Ensure the design accommodates the specific -3V to -3.8V operating range and the 8-TSSOP footprint. Consider the RoHS exemption if environmental compliance is mandatory for the final assembly.

Flip Flops Part Context

Part of the 100LVEL family of low-voltage ECL devices, offering enhanced speed compared to standard 10EL variants. It shares functional similarities with MC100EL31D (SOIC) and MC100EL31DG (RoHS-compliant SOIC), differing primarily in package type and regulatory compliance status.

Flip Flops Replacement Considerations

MC100EL31D offers identical functionality in an 8-SOIC package. MC100EL31DG provides the same electrical performance in an 8-SOIC package with RoHS compliance. Verify pinout compatibility and thermal requirements when substituting.
