CDC2351DWRG4

Overview

The CDC2351DWRG4 is a fanout buffer and clock distribution device manufactured by Texas Instruments. It provides a single circuit with a 1:10 input-to-output ratio, designed to distribute clock signals in digital systems. The device accepts LVTTL inputs and generates LVTTL outputs, supporting a maximum operating frequency of 100 MHz. It operates within a supply voltage range of 3 V to 3.6 V and is rated for an ambient temperature range of 0°C to 70°C. The component is housed in a 24-SOIC surface-mount package.

Feature Summary

• Single-channel fanout buffer with 1:10 distribution ratio
• Supports LVTTL input and output logic levels
• Maximum operating frequency of 100 MHz
• Operates on a 3 V to 3.6 V power supply

Applications

• Clock signal distribution in high-speed digital circuits
• Buffering reference clocks for multiple loads
• LVTTL-compatible system interconnects

Procurement Notes

Verify the specific revision level and manufacturing date code upon receipt. Confirm that the 24-SOIC package dimensions match the design footprint requirements. Ensure the supply voltage remains strictly within the 3 V to 3.6 V range to maintain signal integrity and prevent device damage during operation.

Selection Notes

Select this component when a single-ended LVTTL clock source requires expansion to ten identical loads. It is suitable for applications where propagation delay is less critical than fanout capability. Compare against differential drivers if noise immunity is a primary constraint, as this device uses single-ended signaling.

Part Context

This part belongs to the Texas Instruments clock buffer family. It serves as a standard solution for distributing low-voltage TTL compatible clock signals. The DWRG4 suffix indicates the 24-SOIC tape-and-reel packaging configuration.

Replacement Considerations

Check for direct pin-compatible alternatives from the same manufacturer series. Verify that any substitute maintains the 1:10 ratio and LVTTL compatibility. Ensure the replacement supports the required 100 MHz frequency and 3.6 V maximum supply voltage.
