CDC351IDWRG4

Overview

The CDC351IDWRG4 is a single-circuit fanout buffer manufactured by Texas Instruments, designed for clock distribution applications. It provides a 1:10 input-to-output ratio with LVTTL input and LVTTL tri-state outputs. The device supports maximum frequencies of 100 MHz and operates on a supply voltage range of 3V to 3.6V. It is housed in a 24-SOIC package (0.295 inch width) and is rated for an operating temperature range of -40°C to 85°C. This component is packaged in Tape & Reel format.

Feature Summary

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

Applications

• Clock distribution networks requiring 1:10 fanout
• System boards utilizing LVTTL logic families
• Industrial equipment operating between -40°C and 85°C

Procurement Notes

Verify the specific ordering suffix G4 against manufacturer documentation to confirm RoHS compliance and environmental classification. Confirm that the Tape & Reel packaging matches the required handling specifications for automated assembly processes. Ensure the 24-SOIC footprint aligns with the target PCB design constraints.

Selection Notes

Select this component when a single LVTTL source must drive ten LVTTL loads. Verify that the system power supply remains strictly within the 3V to 3.6V window to ensure proper operation. Check that the 100 MHz frequency limit meets the signal requirements. Consider the 24-SOIC package dimensions if space is constrained.

Part Context

This part belongs to the Texas Instruments clock buffer family. It serves as a distribution element for digital clock signals. The device replaces older variants like the CDC351IDW while maintaining similar electrical characteristics. It is distinct from differential drivers or multi-channel buffers.

Replacement Considerations

The CDC351IDWR is a direct functional equivalent in tape-and-reel packaging. The CDC351IDW is available in tube packaging. Verify pin compatibility and electrical parameters before substituting.
