551MLF

Overview

The Renesas 551MLF is a low-cost, high-speed clock buffer featuring one input and four outputs. It belongs to the ClockBlocks family and utilizes an advanced CMOS process. The device operates within a supply voltage range of 3 V to 5.5 V and supports maximum input frequencies up to 160 MHz. Key electrical parameters include a maximum propagation delay of 8 ns. It is housed in an 8-pin SOIC package with surface-mount installation. The component functions as a non-inverting output clock buffer suitable for general timing applications.

Feature Summary

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

Applications

• General clock distribution systems
• Timing signal buffering in electronic circuits
• Low-cost clocking solutions requiring single-to-multi-channel conversion

Procurement Notes

Verify the specific suffix 'MLF' against official Renesas documentation to confirm package type and temperature grade. Ensure compatibility with the required operating voltage range of 3 V to 5.5 V. Confirm that the 8-lead SOIC package dimensions meet the target PCB layout constraints before finalizing procurement decisions.

Selection Notes

Select this component when a low-cost, single-input to four-output clock buffer is required. It is appropriate for designs needing up to 160 MHz operation with a 3 V to 5.5 V supply. Consider the 8 ns propagation delay and SOIC-8 package form factor during schematic capture and layout planning.

Part Context

The 551MLF is part of the Renesas 551 series, classified as a ClockBlocks family member. This series represents a line of low-cost, small-form-factor clock buffers designed for efficient signal distribution without complex phase-locked loop functionality.
