8304AM-01LFT

Overview

The Renesas 8304AM-01LFT is a low skew, 1-to-4 inverting fanout buffer designed for clock distribution applications. It accepts LVCMOS or LVTTL inputs and provides four corresponding outputs. The device operates with a maximum frequency of 166 MHz and supports mixed supply modes, allowing the input (VDD) to run at 3.3V while outputs (VDDO) operate at either 3.3V or 2.5V. Packaged in an 8-lead SOIC, it ensures well-defined performance with guaranteed output skew of 50ps maximum and part-to-part skew of 600ps maximum.

Feature Summary

• 1-to-4 Inverting Fanout Buffer with LVCMOS/LVTTL compatibility
• Maximum operating frequency of 166 MHz
• Low skew characteristics: 50ps output skew, 600ps part-to-part skew
• Mixed voltage operation: 3.3V input with 3.3V or 2.5V output options

Applications

• Clock distribution networks requiring precise timing
• Systems demanding repeatability in clock signal integrity
• Board space-constrained designs utilizing 8-lead SOIC packaging

Procurement Notes

The 8304AM-01LFT is identified as obsolete and no longer manufactured by Renesas Electronics Corporation. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or third-party suppliers. Buyers must account for potential lead time variations and ensure compliance with RoHS standards, as the component is available in lead-free packages.

Selection Notes

Select this component when a single-ended LVCMOS or LVTTL clock source needs to drive four loads with minimal skew. It is suitable for designs requiring mixed voltage domains, specifically 3.3V logic driving 2.5V or 3.3V receivers. Engineers should consider the 166 MHz frequency limit and the 8-SOIC package dimensions during PCB layout. Due to its obsolescence, alternative solutions like the 5PB1104CMGI8 may be evaluated for new designs.

Part Context

This part belongs to the 8304A family of high-performance clock buffers from IDT, now part of Renesas Electronics. The family specializes in low-skew fanout buffers for digital systems. The specific suffix 'AM-01' denotes the inverting configuration and temperature/package variant, while 'LFT' indicates a lead-free, RoHS-compliant assembly. These components are widely used in telecommunications and computing infrastructure.

Replacement Considerations

The 5PB1104CMGI8 is listed as a substitute part number by Renesas. Designers should verify pin compatibility and electrical specifications against the original datasheet before implementation.
