CDC351DB

Overview

The CDC351DB 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-compatible inputs and outputs that support tri-state functionality. The device operates within a supply voltage range of 3V to 3.6V and supports maximum frequencies up to 100 MHz. Packaged in a 24-SSOP (5.30mm width) surface-mount case, it is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Single circuit providing 1:10 fanout distribution
• LVTTL input and LVTTL tri-state outputs
• Maximum operating frequency of 100 MHz
• Supply voltage range of 3V to 3.6V

Applications

• Clock signal distribution in digital systems
• Buffering LV TTL clock sources
• Multi-load clock tree architectures

Procurement Notes

Verify the package type against project requirements, as this specific part number utilizes a 24-SSOP tube packaging format. Confirm that the commercial temperature range of 0°C to 70°C meets the environmental specifications for the intended deployment scenario before finalizing procurement decisions.

Selection Notes

Select the CDC351DB when a single-input, ten-output buffer is required for LVTTL clock signals. Ensure the design environment remains within the 0°C to 70°C operational limit. For industrial temperature ranges or differential signaling requirements, alternative models such as the CDC351IDW series should be evaluated instead.

Part Context

This component belongs to the Texas Instruments clock buffer family, specifically engineered for low-power clock distribution tasks. It serves as a standard solution for expanding clock signals in consumer electronics and general-purpose digital logic circuits where LVTTL compatibility is essential.

Replacement Considerations

The CDC351IDB offers identical electrical characteristics but extends the operating temperature range to -40°C ~ 85°C. The CDC351IDWR variant provides tape-and-reel packaging for automated assembly processes while maintaining the extended temperature rating.
