Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required packaging and environmental standards. Confirm that the 20-SOIC package dimensions match the target PCB footprint. Check RoHS compliance status as defined in the official documentation before finalizing procurement specifications.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring robust bidirectional data transfer across multiple lines with low power consumption. The LVCR series offers improved performance over standard LVC devices. Ensure the system voltage remains within the 2 V to 3.6 V range and that the load capacitance requirements are met for the specified propagation delay.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVCR2245A family of bus transceivers. It shares functional similarities with other octal transceivers like the SN74LVC245 but utilizes specific LVCR technology for enhanced characteristics. The 'ADWR' suffix indicates the SOIC-20 package and reel tape packaging format.
