CDC351IDWR

Overview

The CDC351IDWR is a single fanout buffer from Texas Instruments, designed for clock distribution applications. It provides one input to ten outputs with an LVTTL interface and tri-state capability. The device operates within a supply voltage range of 3V to 3.6V and supports maximum frequencies up to 100 MHz. It is housed in a 24-SOIC surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Single circuit fanout buffer with 1:10 input-to-output ratio
• LVTTL input and LVTTL/Tri-state output interfaces
• Maximum operating frequency of 100 MHz
• Available in 24-SOIC surface-mount package

Applications

• Clock distribution networks
• Fanout buffering for digital systems
• High-speed data transmission timing circuits

Procurement Notes

Verify the specific ordering suffix 'WR' corresponds to the Tape & Reel packaging configuration as indicated in the source data. Confirm that the component status is obsolete before initiating procurement actions. Ensure the selected quantity aligns with the manufacturer's standard reel sizes if applicable.

Selection Notes

Select this component when a single-ended LVTTL clock signal requires expansion into ten separate lines. The 100 MHz frequency limit suits moderate-speed digital designs. Verify that the system power supply remains strictly between 3V and 3.6V to ensure proper logic level operation and avoid damage.

Part Context

This part belongs to the Texas Instruments clock buffer and driver category. It serves as a distribution element within larger timing architectures, converting a single source signal into multiple synchronized outputs for downstream logic components.
