• Asynchronous communication between data buses
• Memory interface circuits in computing systems
• Microprocessor-based system interconnects
• High-speed data routing applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free packaging compliant with RoHS standards. Confirm the SOIC-20 package dimensions match your PCB footprint requirements. Ensure the operating temperature range aligns with your system's thermal environment. Check for any specific handling instructions related to moisture sensitivity level classification during storage and assembly.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed octal bus interfacing is required within the ABT performance class. Compare against LV or LVC families if lower voltage operation is necessary, as this part typically requires higher supply voltages. Consider the 20-SOIC package availability versus TSSOP alternatives if board space is constrained. Verify that the drive current capabilities meet the load requirements of the connected bus lines.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74ABT family, which utilizes Advanced BiCMOS technology to achieve high speed while maintaining low power consumption. The SN74ABTR2245 variant specifically denotes the reel-packaged version of the standard SN74ABT2245. It serves as a bridge for transferring data between different logic domains or expanding bus width in digital designs.
