CDC204DWR

Overview

The CDC204DWR is a clock buffer and driver manufactured by Texas Instruments, designed for high-speed signal distribution. It features a 6:6 input-to-output ratio, allowing one input signal to drive six outputs simultaneously. The device operates with a maximum frequency of 80 MHz and supports CMOS input and output logic levels. It requires a single power supply voltage ranging from 4.75 V to 5.25 V. The component is housed in a 20-SOIC package with a width of 7.50 mm and is rated for an operating temperature range of 25°C to 70°C.

Feature Summary

• Six-to-six (6:6) fan-out buffering capability
• Maximum operating frequency of 80 MHz
• CMOS input and output compatibility
• Single 5 V supply operation (4.75 V to 5.25 V)

Applications

• Clock distribution networks requiring multiple buffered outputs
• Digital systems utilizing CMOS logic families
• Signal integrity enhancement in high-frequency circuits

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging type, as the DWR suffix typically indicates tape and reel packaging. Ensure the procurement source provides valid traceability for the 20-SOIC surface-mount device. Confirm that the supplied units match the specified 4.75 V to 5.25 V voltage requirements and 80 MHz frequency limits before integration into the design.

Selection Notes

Select this component when a 6-channel fan-out buffer is required for CMOS clock signals up to 80 MHz. It is suitable for applications needing a single 5 V supply rail. Compare against other members of the CDC series if differential signaling or different voltage ranges are necessary. Ensure the thermal environment remains within the 25°C to 70°C commercial grade specification during operation.

Part Context

This part belongs to the Texas Instruments family of clock buffers and drivers. It serves as a non-inverting buffer solution for distributing clock signals across digital circuits. The 20-SOIC package allows for surface-mount assembly on standard PCB layouts. It is distinct from differential drivers like the CDCLV series, focusing instead on single-ended CMOS signal propagation.

Replacement Considerations

Check for direct pin-compatible replacements within the same CDC series that offer extended temperature ranges or alternative packaging options. Verify that any substitute maintains the 6:6 ratio and 80 MHz frequency capability while supporting the 5 V supply voltage.
