Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation as Rochester Electronics, LLC, which acts as an authorized distributor of original factory components. Confirm the specific suffix 'G' indicates lead-free compliance if required by your assembly process. Ensure the TSSOP-56 package matches your PCB footprint design. Request date codes to assess component freshness. Validate authenticity through official channel documentation.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit width is required for synchronous data transfer. The ACT series offers faster switching speeds compared to standard HC or HCT families. The registered nature allows for latching data at the destination. Consider the 3-state capability for multiplexed bus systems. Verify voltage compatibility with the host system's 5V logic domain.

Buffers, Drivers, Receivers, Transceivers Part Context

Rochester Electronics specializes in providing continuous availability of semiconductors, including obsolete and hard-to-find parts. They are authorized by over 70 leading manufacturers.
