CDC2351DW

Overview

The CDC2351DW is a single-circuit fanout buffer manufactured by Texas Instruments, designed for clock distribution applications. It provides a 1:10 output ratio with LVTTL-compatible inputs and outputs. The device supports maximum operating frequencies of 100 MHz and operates within a supply voltage range of 3V to 3.6V. Packaged in a 24-SOIC surface-mount case (0.295" width), it is rated for an industrial temperature range of 0°C to 70°C. This component functions as a dedicated signal distributor without differential input or output capabilities.

Feature Summary

• 1:10 Fanout Buffer Configuration
• LVTTL Input/Output Compatibility
• 100 MHz Maximum Frequency
• 3V to 3.6V Supply Voltage Range

Applications

• Clock distribution networks
• Signal buffering for digital systems
• Board-level timing distribution

Procurement Notes

Verify the package type corresponds to Bulk or Tube formats when sourcing. Confirm the specific temperature grade matches the 0°C to 70°C requirement for the target environment. Ensure the 24-SOIC footprint aligns with the PCB layout specifications before procurement.

Selection Notes

Select this component when a single-ended LVTTL signal requires expansion into ten identical outputs. The 100 MHz frequency limit suits standard digital clocking needs. Verify that the 3V-3.6V supply rail is available and stable for the application circuit design.

Part Context

This part belongs to the Clock Buffers and Drivers category from Texas Instruments. It serves as a signal integrity solution for distributing clock signals across multiple loads while maintaining LVTTL logic levels.

Replacement Considerations

Check for compatible 1:10 LVTTL fanout buffers with similar 24-SOIC packaging and 3V-3.6V operation if substitution is required.
