CDC351IDBR

Overview

The CDC351IDBR 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 inputs 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. Packaged in a 24-SSOP (0.209 inch width) format within a tape and reel configuration, it functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Single circuit fanout buffer with 1:10 distribution ratio
• LVTTL input and LVTTL tri-state output capabilities
• Maximum operating frequency of 100 MHz
• Operates on 3V to 3.6V supply voltage

Applications

• Clock distribution networks
• System timing synchronization
• Digital signal processing interfaces

Procurement Notes

Verify the package type matches the required 24-SSOP form factor. Confirm that the 100 MHz frequency limit meets system requirements. Ensure the 3V to 3.6V supply voltage aligns with the target power rails. Check the -40°C to +85°C operating temperature range against environmental conditions.

Selection Notes

Select this component when a single-input, ten-output clock buffer is needed. The LVTTL interface compatibility is suitable for standard logic families. The tri-state output feature allows for bus sharing or controlled signal gating. Verify pin compatibility if replacing older variants like the IDW tube version.

Part Context

This part belongs to the Texas Instruments clock buffer family. It serves as a low-skew driver for distributing clock signals across multiple loads. The TR suffix indicates tape and reel packaging, optimized for automated surface-mount assembly processes.

Replacement Considerations

The CDC351IDW is a compatible alternative in tube packaging. Both share identical electrical specifications and pinouts. Verify that the manufacturing lot date codes meet project timelines.
