CDC208N

Overview

The CDC208N is a low skew clock driver manufactured by Texas Instruments, designed for high-speed digital signal distribution. It functions as a fanout buffer with two independent circuits, converting TTL input signals to CMOS outputs. The device supports a maximum operating frequency of 60 MHz and operates within a supply voltage range of 4.5 V to 5.5 V. It is housed in a 20-SOIC surface-mount package and is rated for an industrial temperature range of -40°C to +85°C.

Feature Summary

• Low skew performance for precise timing distribution
• Dual-channel architecture with TTL-to-CMOS conversion
• Maximum frequency capability of 60 MHz
• Standard 20-pin SOIC surface-mount packaging

Applications

• High-speed data acquisition systems requiring precise clock synchronization
• Digital signal processing (DSP) clock distribution networks
• Communication equipment utilizing CMOS logic interfaces

Procurement Notes

Verify the specific package variant against the 20-SOIC (0.209 inch width) specification. Confirm that the application environment remains within the -40°C to +85°C operating temperature limits. Ensure the system power supply strictly adheres to the 4.5 V to 5.5 V range to maintain signal integrity and device reliability.

Selection Notes

Select this component when a dual-channel clock buffer with TTL inputs and CMOS outputs is required. It is suitable for designs needing low skew distribution at frequencies up to 60 MHz. Consider alternative packages if board space constraints differ from the standard 20-SOIC footprint or if different voltage levels are necessary.

Part Context

The CDC208N belongs to the family of low skew clock drivers from Texas Instruments. These components are engineered to minimize propagation delay differences between outputs, ensuring synchronized signal delivery across multiple loads in complex digital systems.

Replacement Considerations

Consult official cross-reference lists for compatible devices offering identical pinouts and electrical characteristics. Verify that any substitute maintains the same TTL input and CMOS output compatibility along with the 60 MHz frequency limit.
