Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix MSAX against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the ordering number with official distributor catalogs to confirm availability status, as this part may be subject to lifecycle changes or obsolescence notices from onsemi.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring eight-bit bidirectional data transfer with high drive strength. The ACT series offers faster propagation delays compared to standard AC series, making it suitable for higher-speed bus applications. Ensure the system voltage remains within the 4.5 V to 5.5 V range to maintain proper logic level compatibility and output drive characteristics.
