551AMILF

Overview

The 551AMILF is a high-speed single-input to four-output clock buffer from Renesas Electronics. 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 features a maximum propagation delay of 8 ns and consumes an operating supply current of 18 mA. It is housed in an 8-pin SOIC package with dimensions of 4.9 mm length, 3.9 mm width, and 1.5 mm height. The component functions across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Provides fanout capability by distributing a single clock signal to four independent outputs
• Supports high-frequency operation with a maximum input frequency of 160 MHz
• Ensures timing integrity with a maximum propagation delay of 8 ns

Applications

• Distributing clock signals in digital control systems
• Signal routing for level logic applications
• Timing management in general-purpose electronic circuits

Procurement Notes

Verify the specific suffix 'AMI' against official Renesas documentation to confirm the exact temperature grade and package variant. Ensure the selected part matches the required operating temperature range and pin configuration for the target design. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select the 551AMILF when a low-cost, small form-factor clock buffer is required for single-to-four output distribution. Consider this component for designs needing high-speed performance with minimal propagation delay. Evaluate the 8-pin SOIC package constraints against board space limitations. Compare against the dual-version 552-02B if multiple buffers are needed in a single package.

Part Context

The 551 series belongs to Renesas' ClockBlocks family, positioned as a low-cost, high-speed solution for clock buffering. This series includes variants like the 551MILF and 551MLF, which share similar functional architectures but may differ in temperature ranges or packaging. The 551AMILF specifically targets applications requiring reliable clock distribution in standard industrial environments.

Replacement Considerations

The 551MILF and 551MLF are related parts within the same 551 series. Verify compatibility regarding temperature ratings and package dimensions before substitution. The 552-02B serves as a monolithic dual version in a 20-pin QSOP package, offering a different footprint and channel count.
