CDC351DBRG4

Overview

The CDC351DBRG4 is a single fanout buffer manufactured by Texas Instruments, designed for clock distribution applications. It provides one input to ten outputs with an LVTTL input interface and LVTTL tri-state outputs. The device supports a maximum frequency of 100 MHz and operates on a supply voltage ranging from 3V to 3.6V. It is housed in a 24-SSOP package (0.209 inch width) and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Single circuit fanout buffer with 1:10 input-to-output ratio
• LVTTL input compatible with LVTTL tri-state outputs
• Maximum operating frequency of 100 MHz
• Operates within a 3V to 3.6V supply voltage range

Applications

• Clock distribution networks requiring 1:10 fanout
• System timing architectures using LVTTL logic levels
• Board-level clock buffering for digital circuits

Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's current documentation to confirm environmental compliance status and active production lifecycle. Ensure the 24-SSOP tape and reel packaging matches the automated assembly requirements of the target manufacturing line.

Selection Notes

Select this component when a 1:10 fanout buffer with LVTTL compatibility is required. Confirm that the 0°C to 70°C commercial temperature range meets the system's thermal specifications. Verify that the 3V to 3.6V supply voltage aligns with the available power rails in the design.

Part Context

This part belongs to the Texas Instruments clock buffer family, specifically functioning as a fanout buffer for distribution. It serves as a surface-mount solution for routing clock signals across multiple destinations within a single circuit board.

Replacement Considerations

The CDC351IDBR is a similar device offering the same electrical performance but features an extended industrial temperature range of -40°C to 85°C and utilizes a 24-SOIC package instead of SSOP.
