CDC351DWR

Overview

The Texas Instruments CDC351DWR is a single fanout buffer designed for clock distribution applications. It accepts one LVTTL input and provides ten LVTTL tri-state outputs, offering a 1:10 signal ratio. The device supports maximum frequencies of 100 MHz and operates within a supply voltage range of 3V to 3.6V. Packaged in a 24-SOIC surface-mount case with dimensions of 0.295 inches (7.50mm) width, it is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Single circuit providing 1:10 fanout buffering capability
• LVTTL input compatible with LVTTL tri-state outputs
• Maximum operating frequency of 100 MHz
• Operates on a 3V to 3.6V power supply

Applications

• Clock distribution networks requiring signal splitting
• System boards needing LVTTL level translation and buffering
• Digital logic circuits utilizing tri-state output control

Procurement Notes

Verify the specific package variant against project requirements, as the source indicates availability in both Tape & Reel and Cut Tape formats. Confirm that the commercial temperature grade (0°C to 70°C) aligns with the operational environment constraints before finalizing procurement decisions.

Selection Notes

Select this component when a single-ended LVTTL signal requires expansion into ten buffered outputs. Ensure the design accommodates the 3V to 3.6V supply voltage limits. Verify that the 100 MHz frequency ceiling meets the system clock speed requirements and that the 24-SOIC footprint fits the PCB layout constraints.
