CDC208DWRG4

Overview

The CDC208DWRG4 is a dual 1-to-4 clock buffer and driver manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum frequency of 60 MHz. The device features two independent circuits, each providing a 1:4 fanout ratio with TTL input and CMOS output capabilities. It is housed in a 20-SOIC surface-mount package with a width of 7.50mm. The component is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual circuit architecture providing two independent 1:4 clock distribution paths
• TTL input and CMOS output interface compatibility
• Maximum operating frequency of 60 MHz
• Wide supply voltage range from 4.5V to 5.5V

Applications

• Clock distribution networks requiring dual-channel buffering
• Digital systems utilizing TTL inputs and CMOS logic levels
• Industrial equipment operating within extended temperature ranges

Procurement Notes

Verify the specific ordering suffix 'G4' against manufacturer documentation to confirm lead-free status or RoHS compliance details. Ensure the 20-SOIC package dimensions match the target PCB footprint requirements. Confirm that the 4.5V to 5.5V supply voltage aligns with the system power design before procurement.

Selection Notes

Select this component when dual independent clock buffers are required for 1:4 fanout applications. It is suitable for designs needing TTL-compatible inputs and CMOS outputs. Consider the 60 MHz maximum frequency limit and the 20-SOIC package size during layout planning. Verify thermal management needs for the -40°C to +85°C operating range.

Part Context

This part belongs to the CDC208 series of clock drivers and buffers. It serves as a specialized solution for distributing clock signals in digital circuits. The device integrates two separate buffer channels into a single package, optimizing board space compared to using individual single-channel buffers.

Replacement Considerations

Check for direct pin-to-pin replacements within the same family. Verify electrical parameters such as supply voltage and frequency limits for any alternative components. Ensure package compatibility and operational temperature ranges match the original specifications.
