CDC329ADG4

Overview

The CDC329ADG4 is a single-circuit fanout buffer manufactured by Texas Instruments, designed for clock distribution applications. It accepts TTL-compatible input signals and provides six CMOS outputs with a 1:6 ratio. The device supports maximum operating frequencies up to 80 MHz and functions within a supply voltage range of 4.75V to 5.25V. Packaged in a 16-SOIC surface-mount case measuring 0.154 inches (3.90mm) wide, it operates reliably across an industrial temperature range of -40°C to 85°C without differential signaling capabilities.

Feature Summary

• Single circuit configuration providing one input to six outputs
• Supports maximum frequency of 80 MHz
• TTL input compatible with CMOS output drivers
• Operates on 4.75V to 5.25V power supply

Applications

• Clock signal distribution in digital systems
• Fanout buffering for timing circuits
• Industrial control system clocking

Procurement Notes

Verify the specific ordering suffix 'G4' against current manufacturer documentation to confirm compliance status and package details. Ensure the selected variant matches the required 16-SOIC footprint and lead-free specifications defined in the official datasheet before finalizing procurement orders.

Selection Notes

Select this component when a single TTL source must drive multiple CMOS loads at frequencies up to 80 MHz. Confirm that the 16-SOIC package dimensions fit the PCB layout constraints. Verify that the 4.75V to 5.25V supply voltage aligns with the system's power architecture requirements.

Part Context

This part belongs to the CDC329 family of clock buffers. The 'G4' suffix typically indicates lead-free manufacturing and RoHS compliance, consistent with Texas Instruments' product naming conventions for environmental upgrades. It serves as a direct replacement for earlier non-G4 versions where pin compatibility remains unchanged.

Replacement Considerations

Check for CDC329AD variants if lead-free certification is not required. Verify pin-to-pin compatibility with other 1:6 fanout buffers from the same series before substitution.
