83940DYLFT

Overview

The Renesas Electronics 83940DY-01LFT is a clock buffer featuring 18 LVCMOS outputs. It belongs to the 83940-01 series and is classified under Clock & Timer ICs. The component is manufactured by Renesas Electronics, formerly IDT. It operates with CMOS logic levels and utilizes an LQFP-32 package measuring 7 x 7 mm with a height of 1.40 mm. The device is designated as End-of-Life (EOL).

Feature Summary

• 18 LVCMOS output channels for clock distribution.
• Low skew clock driver architecture.
• CMOS technology with differential input multiplexer.
• Available in LQFP-32 surface-mount package.

Applications

• General clock buffering in digital systems.
• LVCMOS interface timing distribution.

Procurement Notes

This component is officially listed as End-of-Life (EOL) by Renesas Electronics. Availability is restricted, and it may not be sold in all regions through standard distributors like Mouser. Verification of current stock status and alternative sourcing strategies is required before procurement planning.

Selection Notes

Select this part only if 18 LVCMOS outputs are required and the LQFP-32 package fits the design constraints. Due to its EOL status, long-term supply continuity cannot be guaranteed. Designers should evaluate pin-compatible or functionally equivalent newer generation clock buffers from the manufacturer's active portfolio.

Part Context

The 83940DY-01LFT is part of the broader 83940 family of low skew clock drivers originally developed by Integrated Device Technology (IDT), which was acquired by Renesas Electronics. The 'DY' suffix indicates the LQFP-32 package, while '01LFT' denotes specific electrical and packaging variations within the series.

Replacement Considerations

As an EOL component, direct substitutes are not explicitly confirmed in public documentation. Engineers should consult Renesas for recommended obsolescence management solutions or next-generation replacements within their clock buffer lineup.
