CDC341DWR

Overview

The CDC341DWR is a single-channel fanout buffer and clock distribution integrated circuit manufactured by Texas Instruments. It provides an eight-fold output expansion with a maximum operating frequency of 80 MHz. The device accepts TTL-compatible inputs and generates TTL-compatible outputs, utilizing a 20-SOIC surface-mount package. It operates within a supply voltage range of 4.75 V to 5.25 V and supports commercial temperature grades from 0°C to 70°C.

Feature Summary

• Single-channel architecture providing one input to eight outputs
• Maximum switching frequency of 80 MHz for high-speed signal distribution
• TTL-compatible input and output logic levels
• Standard 20-SOIC package with 7.50 mm width

Applications

• Clock signal distribution in synchronous digital systems
• Fanout buffering for control signals
• High-speed data bus driving applications

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure the selected variant matches the required 20-SOIC footprint and commercial temperature range for the intended design environment.

Selection Notes

Select this component when a single source requires driving up to eight 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 0°C to 70°C operating temperature range meets the environmental requirements of the final assembly.

Part Context

This part belongs to the family of clock buffers and drivers designed for signal integrity and distribution. It serves as a standard solution for expanding clock lines in digital circuits where propagation delay and load capacitance management are critical for timing accuracy.

Replacement Considerations

Consult the manufacturer's replacement guide for pin-compatible or functionally equivalent alternatives. Verify that any substitute maintains the 1:8 ratio, 80 MHz frequency limit, and 20-SOIC package dimensions.
