Procurement Notes

Verify the specific suffix 'DR' corresponds to the tape-and-reel packaging configuration required for your assembly process. Confirm that the SOIC-16 package dimensions align with your PCB footprint design rules. Ensure the operating temperature range meets your environmental specifications. Cross-reference the datasheet for pinout compatibility if replacing existing components. Validate RoHS compliance status for regulatory adherence in your target market.

Selection Notes

Choose this component when low skew is critical for maintaining signal integrity in high-frequency applications. Consider the supply voltage requirements to ensure compatibility with your system's power rails. Evaluate the output drive capability against the load capacitance of your destination devices. Assess the package size constraints for space-sensitive designs. Verify the input logic levels match your source clock signals.

Part Context

The CDC303DR belongs to Texas Instruments' family of clock drivers and buffers, which are essential for managing timing signals in complex electronic systems. These components facilitate the distribution of reference clocks to multiple downstream devices while minimizing timing errors. The DR suffix indicates a specific reel-based packaging option suitable for automated surface-mount manufacturing processes.

Replacement Considerations

Check for direct cross-reference part numbers from Texas Instruments or other manufacturers offering equivalent low-skew clock drivers in SOIC-16 packages. Verify functional compatibility regarding supply voltage, output logic types, and maximum frequency specifications before substitution.
