CDC204DWG4

Overview

The CDC204DWG4 is a clock buffer and driver manufactured by Texas Instruments, housed in a 20-SOIC surface-mount package. It features a 6:6 input-to-output ratio with CMOS inputs and outputs. The device supports a maximum frequency of 80 MHz and operates on a supply voltage range of 4.75 V to 5.25 V. It is designed for commercial temperature conditions ranging from 0°C to +70°C. This component functions as a single-circuit buffer/driver within the clock distribution category.

Feature Summary

• Six-channel clock buffer with 1:1 input-to-output ratio per channel
• CMOS logic compatible inputs and outputs
• Maximum operating frequency of 80 MHz
• Standard 20-pin SOIC package for surface mount installation

Applications

• Clock signal distribution in digital systems
• Buffering clock lines for CMOS-based logic circuits
• Signal integrity maintenance in high-speed data paths

Procurement Notes

Verify the specific ordering suffix G4 against the manufacturer's datasheet to confirm lead-free status and RoHS compliance details. Ensure the procurement source provides the original manufacturer documentation rather than third-party summaries to validate the exact electrical characteristics and pinout configuration for the 20-SOIC package.

Selection Notes

Select this component when a six-channel buffer is required for 5V CMOS clock signals up to 80 MHz. Confirm that the system environment remains within the 0°C to +70°C operating temperature range. Verify that the PCB layout supports the 20-SOIC footprint dimensions and that the power supply rails are stable between 4.75 V and 5.25 V.

Part Context

This part belongs to the Texas Instruments catalog of clock drivers and buffers. It serves as a solution for distributing clock signals across multiple loads while maintaining signal integrity. The device is distinct from dividers or multipliers, focusing solely on buffering and driving capabilities for synchronous digital designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family that may offer different packaging options or extended temperature ranges. Verify that any substitute maintains the 6:6 ratio and 80 MHz frequency capability to ensure functional equivalence in the existing circuit design.
