Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the complete part number including the G4 suffix to ensure compliance with RoHS directives and lead-free manufacturing standards. Confirm the SOIC-20 package variant matches the required PCB footprint. Cross-reference the datasheet revision history to validate electrical characteristics against specific design requirements before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing between systems requiring HCT logic compatibility and higher drive capabilities than standard HC devices. The three-state feature allows multiple drivers to share a common data bus without contention. Ensure the application voltage remains within the specified 4.5 V to 5.5 V range to maintain signal integrity and timing specifications.
