CDC351IDW

Overview

The CDC351IDW is a single fanout buffer manufactured by Texas Instruments, designed for clock distribution applications. It features a 1:10 input-to-output ratio with LVTTL-compatible 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-SOIC surface-mount case (0.295 inch width), it functions within 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 compatibility
• Maximum operating frequency of 100 MHz
• Surface mount 24-SOIC package

Applications

• Clock signal distribution in digital systems
• Fanout buffering for LVTTL logic interfaces
• Industrial control system timing circuits

Procurement Notes

Verify the specific ordering suffix 'DW' corresponds to the tube packaging configuration when sourcing. Confirm that the 24-SOIC footprint matches the target PCB design constraints. Ensure the 3V to 3.6V supply voltage aligns with the system power rails before integration.

Selection Notes

Select this component when a single-ended LVTTL input requires expansion into ten tri-stateable LVTTL outputs. The 100 MHz frequency limit defines the maximum clock speed capability. Verify that the 24-SOIC package dimensions fit the available board space and thermal requirements for the -40°C to 85°C operating environment.

Part Context

This part belongs to the Texas Instruments clock buffer family, specifically engineered for high-speed signal integrity. The CDC351 series provides reliable fanout capabilities for synchronous digital designs requiring precise timing distribution across multiple loads.

Replacement Considerations

Check for direct pin-compatible alternatives from the same manufacturer or other vendors offering identical 1:10 LVTTL fanout buffers in 24-SOIC packages. Verify electrical parameter equivalence regarding propagation delay and drive strength.
