Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DGGR' corresponds to the TSSOP-48 package and tape-and-reel quantity when ordering. Confirm RoHS compliance status through official manufacturer documentation. Ensure the design supports the 5.5-V input tolerance if interfacing with legacy 5-V logic sources. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when 16-bit parallel buffering is required with mixed-voltage compatibility. The LVCH series offers higher speed compared to standard LVC counterparts. Consider the TSSOP-48 package constraints for PCB layout. Verify that the 5.5-V input tolerance meets the source device output requirements without additional level shifting components.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to Texas Instruments' Widebus family of 16-bit logic devices. It shares architectural similarities with the SN74LVT162245A transceiver but functions specifically as a unidirectional buffer. The LVCH technology combines low power consumption with high-speed performance, suitable for modern embedded applications requiring voltage translation capabilities.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74LVCH16541ADGGR may be functionally replaced by other 16-bit LVCH buffers such as the SN74LVCH16245A if bidirectional operation is acceptable. Verify pinout compatibility before substitution. Check propagation delay specifications to ensure timing margins are maintained in the target application.
