Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix RE4 indicates lead-free composition and environmental compliance when sourcing. Confirm the package designation matches the required 20-TSSOP footprint for PCB layout integration. Ensure the operating temperature range aligns with system requirements, as industrial variants may differ. Cross-reference the manufacturer part number against official distributors to avoid counterfeit components.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between systems requiring 5 V logic levels and high-speed data transfer. The HCT series ensures compatibility with HC logic families while offering improved noise margins. Consider the TSSOP package for space-constrained surface-mount designs. Evaluate propagation delay specifications against system timing constraints before finalizing the design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part is a member of the SN74HCT541 family, which includes variants like SN74HCT541PWR and SN74HCT541DWR. These devices share identical logical functionality but differ in packaging and environmental certifications. The RE4 suffix specifically denotes lead-free construction and RoHS compliance, distinguishing it from older or non-compliant versions in the same functional family.
