Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'SJX' against the official onsemi datasheet to confirm package type and tape/reel specifications. Ensure the ordering part number matches the exact mechanical dimensions required for your PCB footprint. Cross-reference the manufacturer's latest documentation to confirm active status and any recent pinout or electrical parameter updates before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring eight-bit bidirectional data transfer with high drive strength. The wide 2V-6V supply range allows compatibility with various logic families. Consider the 8ns propagation delay for timing constraints in your bus architecture. Verify that the SOIC-20 package fits your assembly capabilities and thermal requirements compared to alternative packages like TSSOP.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the 74AC series of high-speed CMOS logic products. It serves as a standard interface solution for connecting microprocessors, memory, and peripheral devices in digital systems.
