553MILFT

Overview

The Renesas Electronics 553MILFT is a low skew, single-input to four-output clock buffer belonging to the ClockBlocks family. It operates within a supply voltage range of 2.375 V to 5.25 V and supports maximum input frequencies up to 200 MHz. The device features a maximum propagation delay of 5 ns and consumes 25 mA of operating current. Packaged in an 8-pin SOIC format for surface mount installation, it functions reliably across commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature ranges.

Feature Summary

• Low skew output performance with maximum skew of 50 ps
• Single input to four output configuration
• Output enable pin for tri-stating outputs
• 5 V tolerant input capability

Applications

• Clock distribution networks requiring low skew
• High-speed digital systems synchronization
• Embedded systems timing applications

Procurement Notes

Verify the suffix 'FT' indicates tape-and-reel packaging distinct from the tube-packaged 'LF' variant. Confirm RoHS compliance status via official datasheets. Check lead-free certification requirements against project specifications. Validate package dimensions and pinout compatibility during integration planning.

Selection Notes

Select this component when low skew is critical compared to standard buffers like the 551 series. Ensure supply voltage aligns with the 2.375 V to 5.25 V operational window. Consider the 200 MHz frequency limit for signal integrity. Compare power consumption against alternatives if battery efficiency is a priority.

Part Context

The 553MILFT is part of the broader 553M series, which includes variants such as 553MLF and 553MILF. These devices share core electrical characteristics but differ in packaging formats. The 553S series offers improved jitter performance with lower voltage operation, while the 551 series provides a lower-cost alternative with higher propagation delay.

Replacement Considerations

The 553MLF serves as a direct functional substitute with identical electrical parameters but differs in tube packaging. For lower voltage applications, the 553SDCGI8 offers enhanced jitter performance in a smaller package. The 551MILFT provides a cost-effective option with slightly reduced speed specifications.
