Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific revision status, as some listings indicate this part may be obsolete or have limited availability. Confirm the package type matches the design footprint, specifically the 56-SSOP variant. Ensure the operating voltage requirements align with the 2.7V to 3.6V specification before integration into the final circuit design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require simultaneous buffering and latching of 16-bit data words. It is suitable for applications needing isolation between source and destination buses while maintaining data integrity through registered outputs. Consider the thermal performance of the SSOP package if multiple units are placed closely together on the PCB.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the Texas Instruments LVT (Low-Voltage TTL) logic family, optimized for 3.3V operation. It serves as a bridge between microprocessors and peripheral devices, providing both signal buffering and temporary data storage. The integrated register feature distinguishes it from standard transceivers by allowing data retention during bus transitions.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for SN74ABT16646DLR for similar functionality with different electrical characteristics. Verify compatibility with SN74LVT16646DL if the reel packaging differs but the die remains identical. Ensure any substitute maintains the 56-SSOP form factor and 3.3V operating range.
