Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'A' against official datasheets to confirm it denotes the automotive grade variant or specific manufacturing revision. Ensure the SOIC-20 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring wide voltage operation from 2V to 3.6V. It is suitable for designs needing high drive capability with 24mA output current. Consider the extended industrial temperature range if operating in harsh environments. Compare propagation delays against other LVC series parts if timing constraints are critical.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments SN74LV245 family of octal bus transceivers. It shares functional similarities with standard LVC devices but offers specific voltage and temperature characteristics defined by its series designation. It serves as a key interface component for managing data flow across multiple digital buses in complex electronic architectures.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74LVC245ADWRG4 as a potential alternative within the same manufacturer lineup. Verify pin compatibility and electrical parameters before substitution. Other manufacturers may offer equivalent octal bus transceivers, but ensure voltage ranges and drive strengths align with the original design specifications.
