CDC329AD

Overview

The CDC329AD is a fanout buffer manufactured by Texas Instruments, designed for clock distribution applications. It features a single circuit with a 1:6 input-to-output ratio, converting TTL inputs to CMOS outputs. The device supports a maximum frequency of 80 MHz and operates within a supply voltage range of 4.75 V to 5.25 V. It is housed in a 16-SOIC surface-mount package with a width of 3.90 mm. The component is rated for an operating temperature range of -40°C to +85°C.

Feature Summary

• 1:6 Fanout Buffer Configuration
• TTL Input to CMOS Output Conversion
• 80 MHz Maximum Frequency
• 4.75 V to 5.25 V Supply Voltage Range

Applications

• Clock distribution networks
• Digital signal processing systems
• Communication equipment timing circuits

Procurement Notes

Verify the specific ordering suffix against official Texas Instruments documentation to confirm package type and tape/reel specifications. Ensure the selected variant matches the required 16-SOIC surface-mount form factor and industrial temperature rating for the intended design environment.

Selection Notes

Select this component when a single TTL source must drive up to six CMOS loads at frequencies up to 80 MHz. Confirm that the system power supply remains stable between 4.75 V and 5.25 V. Verify that the 16-pin SOIC footprint fits the PCB layout constraints and that the -40°C to +85°C temperature range meets operational requirements.

Part Context

This part belongs to the clock buffer and driver category from Texas Instruments. It serves as a signal conditioning and distribution element within digital logic families, specifically bridging TTL-compatible sources to CMOS-driven destinations in standard 16-pin surface-mount packages.

Replacement Considerations

Consult official cross-reference guides for compatible parts with identical 1:6 ratios, 80 MHz limits, and 16-SOIC packaging. Verify pin compatibility and electrical parameters before substitution.
