8304AMILF

Overview

The Renesas 8304AMILF 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 supports a maximum output frequency of 166 MHz and operates on a single 3.3V supply voltage (3.135V to 3.465V). It is housed in an 8-SOIC package with a width of 3.90mm. The component is characterized for industrial temperature ranges from -40°C to +85°C. Key electrical specifications include a maximum output skew of 50ps and a maximum part-to-part skew of 600ps, ensuring precise timing alignment across multiple clock domains.

Feature Summary

• 1:4 Fanout Buffer with LVCMOS/LVTTL input and output compatibility
• Maximum operating frequency of 166 MHz
• Low skew characteristics: 50ps max output skew and 600ps max part-to-part skew
• Single 3.3V supply operation (3.135V ~ 3.465V)
• Industrial temperature range: -40°C to +85°C

Applications

• Clock distribution networks requiring precise skew control
• System boards needing signal buffering for LVCMOS/LVTTL interfaces
• High-speed digital circuits utilizing 3.3V logic families

Procurement Notes

The 8304AMILF is listed as obsolete and no longer manufactured by Renesas Electronics. Verification of availability should focus on surplus distributors or existing stock rather than direct factory orders. Buyers must confirm the specific revision level and moisture sensitivity status, as production has ceased. Cross-referencing with official End-of-Life (EOL) notices is recommended before finalizing procurement plans.

Selection Notes

Select the 8304AMILF when a 1:4 clock fanout solution is required within the 166 MHz limit. Ensure the design environment supports the -40°C to +85°C temperature range. Verify that the system power rail aligns with the 3.3V requirement. For designs requiring higher frequencies or different logic levels, alternative components such as the 8304AMLFT (commercial grade) or newer Renesas buffers should be evaluated.

Part Context

This component belongs to the 8304A family of low skew fanout buffers. It shares functional similarities with other members like the 8302AMILF (1:2 buffer) but offers four outputs. The 'AMI' suffix typically denotes the industrial temperature grade and specific packaging variant. It serves as a legacy replacement for older clock distribution ICs in established hardware designs.

Replacement Considerations

The 5PB1104CMGI8 is identified as a substitute part number for the 8304A series. Designers should verify pin compatibility and electrical parameters against the original datasheet before implementing this replacement.
