CDC341DWRG4

Overview

The CDC341DWRG4 is a fanout buffer and clock distribution integrated circuit manufactured by Texas Instruments. It provides an 8:1 output ratio from a single TTL-compatible input, supporting maximum frequencies up to 80 MHz. The device operates within a supply voltage range of 4.75 V to 5.25 V and is rated for commercial temperatures between 0°C and 70°C. Housed in a 20-SOIC surface-mount package, it functions as a non-differential clock driver suitable for distributing timing signals across digital systems.

Feature Summary

• Provides 1:8 fanout buffering for clock signal distribution
• Supports maximum operating frequency of 80 MHz
• Compatible with TTL input logic levels
• Operates on a standard 5 V supply (4.75 V to 5.25 V)

Applications

• Clock distribution networks requiring signal splitting
• Digital system timing synchronization
• Bus interface clock buffering

Procurement Notes

Verify the specific revision code associated with the RG4 suffix against the manufacturer's official documentation to ensure compliance with current environmental standards. Confirm that the 20-SOIC tape and reel packaging aligns with automated assembly requirements before finalizing procurement orders.

Selection Notes

Select this component when an 8-channel fanout buffer is required for TTL-level clock signals. Ensure the application environment remains within the 0°C to 70°C operating temperature range. Verify that the 80 MHz frequency limit meets the system's timing requirements and that the 5 V supply voltage is stable.

Part Context

This part belongs to the CDC341 series of clock buffers. The DWRG4 designation indicates a 20-SOIC package, tape and reel shipping format, and RoHS-compliant manufacturing. It serves as a specialized solution for expanding single clock sources into multiple synchronized outputs without differential signaling capabilities.

Replacement Considerations

Consult official cross-reference data for verified substitutes. Generic replacements may differ in propagation delay or drive strength.
