542-DPK

Overview

The Renesas 542-DPK is an active fanout buffer and divider IC designed for clock distribution applications. It features a single circuit with a 1:2 input-to-output ratio, supporting CMOS inputs and three-state CMOS outputs. The device operates within a supply voltage range of 3V to 5.5V and supports a maximum frequency of 156 MHz. It is housed in an 8-SOIC package (0.154 inch width) and is suitable for surface mount installation.

Feature Summary

• Provides one-to-two signal distribution for clock signals
• Supports high-speed operation up to 156 MHz
• Features three-state CMOS outputs for flexible bus driving

Applications

• Clock distribution networks
• Digital system timing circuits
• Drop-in replacement for legacy buffer designs

Procurement Notes

Verify the specific suffix variant against official documentation, as ordering codes may indicate different temperature ranges or packaging options. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure the selected package matches the required PCB footprint specifications.

Selection Notes

Select this component when a single clock source needs to drive two distinct loads with minimal skew. Consider the 3V to 5.5V operating range for compatibility with standard logic families. Evaluate the 8-SOIC package constraints against available board space and thermal requirements for the target application environment.

Part Context

This part belongs to the Renesas clock buffer and driver family, which provides timing signal conditioning and distribution solutions. These components are essential for maintaining signal integrity in complex digital systems requiring precise clock synchronization across multiple subsystems.

Replacement Considerations

The 542-DPK serves as a drop-in replacement for similar legacy buffer devices. Verify pin compatibility and electrical characteristics before substitution. No direct public substitute part numbers are confirmed in the provided data.
