83947AYILN

Overview

The 83947AYILN is a low skew, 1-to-9 LVCMOS fanout buffer manufactured by Renesas Electronics Corporation. It features low impedance LVCMOS/LVTTL outputs designed to drive 50Ω series or parallel terminated loads. The component supports a maximum output frequency of 110MHz and operates within an ambient temperature range of -40°C to 85°C. It is housed in a 32-lead package with lead-free construction.

Feature Summary

• Provides one-to-nine signal distribution for LVCMOS applications
• Engineered for low skew performance across multiple outputs
• Capable of driving 50Ω series or parallel terminated transmission lines

Applications

• LVCMOS signal distribution networks
• High-speed digital circuit buffering
• System clock distribution architectures

Procurement Notes

Verify the obsolete lifecycle status before procurement planning. Confirm regional availability as shipping alerts may indicate restricted supply chains. Ensure compatibility with existing 32-lead package footprints and thermal requirements for the specified operating temperature range.

Selection Notes

Select this component when low skew distribution of LVCMOS signals is required. Verify that the 110MHz frequency limit meets system timing requirements. Ensure the design accommodates the 32-lead package constraints and operates within the -40°C to 85°C environmental specifications.

Part Context

This part belongs to the 83947I family of low skew fanout buffers from Renesas. It serves as a specialized logic device for managing signal integrity in high-speed digital designs. The family focuses on distributing single input signals to multiple outputs with minimal timing deviation.
