CDC351IDWG4

Overview

The CDC351IDWG4 is a single fanout buffer manufactured by Texas Instruments, designed for clock distribution applications. It accepts one LVTTL input and provides ten LVTTL tri-state outputs. The device supports maximum frequencies of 100 MHz and operates on a supply voltage ranging from 3V to 3.6V. It is housed in a 24-SOIC surface-mount package with a width of 7.50mm. The component functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Single circuit configuration providing a 1:10 output ratio
• LVTTL input interface with LVTTL tri-state outputs
• Maximum operating frequency of 100 MHz
• Operates on a 3V to 3.6V power supply

Applications

• Clock distribution networks
• Fanout buffering for digital systems
• System timing signal routing

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and reel specifications. Ensure compatibility with existing board layouts regarding the 24-SOIC footprint and pin assignments. Confirm that the LVTTL logic levels align with the target system requirements before procurement.

Selection Notes

Select this component when a single-ended LVTTL clock signal requires expansion into ten buffered outputs. Verify that the system voltage falls within the 3V to 3.6V range. Ensure the design accommodates the 24-SOIC package dimensions and that the 100 MHz frequency limit meets the application's timing needs.

Part Context

This part belongs to the CDC351 series of clock buffers. The 'G4' suffix typically indicates lead-free and RoHS compliance, while 'DW' denotes the 24-SOIC package. The 'G4' variant may differ in packaging format compared to non-G4 equivalents like the CDC351IDW.

Replacement Considerations

The CDC351IDWRG4 serves as a tape-and-reel alternative to the tube-packaged CDC351IDWG4. Both share identical electrical characteristics and pinouts. Verify package availability requirements before substitution.
