Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix CSJ corresponds to the 14-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow Pb-Free package when sourcing. Confirm that the component meets RoHS specifications and is lead-free as indicated for this series. Ensure the manufacturer designation aligns with Fairchild Semiconductor or its successor entity for accurate part identification.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring ABT series performance with specific SOIC packaging constraints. The 74ABT125CSJ offers distinct sink and source current capabilities suitable for driving bus loads. Consider the disable time being less than enable time to prevent bus contention in multi-driver environments. Verify thermal requirements against the specified -40°C to +85°C operating range.
