CDC328ADR

Overview

The CDC328ADR is a single-channel fanout buffer manufactured by Texas Instruments, designed for clock distribution applications. It accepts TTL input signals and provides six TTL outputs with a 1:6 splitting ratio. The device supports maximum operating frequencies up to 100 MHz and functions within a supply voltage range of 4.75V to 5.25V. It is housed in a 16-SOIC surface-mount package (0.154 inch width) and operates reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Single circuit configuration providing one input to six outputs
• Maximum frequency capability of 100 MHz
• TTL-compatible input and output logic levels
• Operates on standard 5V supply (4.75V–5.25V)

Applications

• Clock signal distribution in digital systems
• Fanout buffering for high-speed data paths
• System timing architecture in industrial equipment

Procurement Notes

Verify the specific ordering suffix 'ADR' against the manufacturer's official documentation to confirm tape and reel packaging specifications. Ensure the selected variant matches the required 16-SOIC footprint and thermal characteristics for the intended application environment.

Selection Notes

Select this component when a 1:6 fanout ratio with TTL compatibility is required at frequencies up to 100 MHz. Confirm that the system power supply remains stable within the 4.75V to 5.25V range. Verify that the 16-SOIC package dimensions fit the available PCB real estate and that the -40°C to 85°C operating range meets environmental requirements.

Part Context

This part belongs to the CDC328 series of clock buffers and drivers. It serves as a distribution element within Texas Instruments' broader portfolio of timing solutions, specifically engineered to drive multiple loads from a single source without signal degradation.

Replacement Considerations

Check for direct cross-references within the CDC328 family or other 1:6 TTL fanout buffers from Texas Instruments. Verify pin-to-pin compatibility and electrical parameter alignment before substituting.
