83940DYILFT

Overview

The Renesas Electronics 83940DYILFT is a clock buffer component belonging to the 83940I-01 series. It functions as an 18-output LVCMOS buffer designed for clock distribution applications. The device is characterized by its ability to drive multiple loads with low skew characteristics, ensuring signal integrity across synchronous systems. This specific part number indicates a lead-free (LF) and halogen-free (H) compliant package variant manufactured by Renesas. The component falls under the broader category of Clock & Timer ICs, specifically serving as a clock driver or distributor within electronic circuits requiring precise timing signals.

Feature Summary

• Provides 18 LVCMOS output channels for fan-out buffering
• Designed for low skew clock distribution applications
• Compliant with RoHS standards (Lead-Free/Halogen-Free)
• Part of the 83940I-01 series family

Applications

• Clock distribution in high-speed digital systems
• Buffering clock signals for multiple synchronous loads
• Embedded systems requiring precise timing alignment

Procurement Notes

The 83940DYILFT is listed as a discontinued product with an End-of-Life (EOL) status. Availability is restricted, and distributors may not stock this item. Verification of current supply status through official Renesas channels or authorized partners is required before procurement planning. Last-time buy options may have expired depending on the notification date.

Selection Notes

When selecting this component, verify that the 18 LVCMOS output configuration matches the system requirements. Ensure compatibility with the input signal levels supported by the 83940I-01 series. Since the part is discontinued, evaluate alternative sources or replacement components from the same manufacturer if long-term supply stability is critical for the design.

Part Context

This component is part of Renesas' portfolio of clock management solutions, derived from IDT technology acquired by Renesas. The 83940 series is known for low skew performance. The 'DYI' suffix typically denotes a specific package type and temperature range, while 'LFT' confirms environmental compliance. It serves as a bridge between source clocks and downstream logic devices.

Replacement Considerations

As a discontinued part, direct replacements should be sought within the 83940I-01 family or newer Renesas clock buffer series. Verify pinout compatibility and electrical specifications such as output drive strength and skew characteristics when substituting.
