551MLFT

Overview

The Renesas Electronics 551MLFT is a low-cost, high-speed clock buffer featuring one input and four outputs. It operates within a supply voltage range of 3 V to 5.5 V and supports maximum input frequencies up to 160 MHz. The device exhibits a maximum propagation delay of 8 ns and is housed in an 8-pin SOIC package with surface-mount installation. It functions as part of the ClockBlocks family, providing non-inverting CMOS outputs suitable for distributing clock signals in digital systems.

Feature Summary

• Single input to four output configuration
• Supply voltage range of 3 V to 5.5 V
• Maximum input frequency of 160 MHz
• Maximum propagation delay of 8 ns

Applications

• General clock distribution in digital circuits
• System timing synchronization
• High-speed data path clocking

Procurement Notes

Verify the specific suffix 'ILFT' against official Renesas documentation to confirm lead-free status and tape-and-reel packaging details. Ensure the operating temperature range requirements align with the industrial specifications found in the datasheet before finalizing procurement orders.

Selection Notes

Select the 551MLFT when a single-source, four-way clock fan-out solution is required within the 3 V to 5.5 V range. Consider this component for designs prioritizing cost-efficiency and small form factor over ultra-low jitter performance compared to higher-end series members.

Part Context

The 551MLFT belongs to the Renesas 551 series of ClockBuffers. This series is characterized by low cost and small physical footprint. The device serves as a fundamental building block for clock distribution networks where moderate speed and multiple output drives are necessary without complex programmability.

Replacement Considerations

Consult official Renesas substitution guides for verified equivalents. Generic cross-references may not match the specific electrical characteristics or pinout configurations required for direct replacement in existing designs.
