Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DBR' corresponds to the SSOP-24 package and tape-and-reel orientation required for your assembly process. Confirm that the LVC logic family meets your system's voltage translation needs between 1.65 V and 3.6 V rails. Ensure environmental compliance documentation matches your regional regulatory standards before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal registered interface is necessary within low-voltage logic environments. The LVC series offers lower power consumption compared to older CMOS families while maintaining adequate drive strength for standard loads. Consider the registered nature of the device if data synchronization on the bus is critical for your application timing requirements.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC543A family of octal registered transceivers manufactured by Texas Instruments. The LVC (Low-Voltage CMOS) technology ensures compatibility with modern low-power digital systems. The 'D' indicates the SSOP package type, while 'BR' specifies the reel packaging configuration for automated surface-mount assembly processes.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVC543APWR serves as a functional alternative in a TSSOP-24 package. SN74ABT543ADBR provides similar functionality but operates at higher voltages using BiCMOS technology. Verify pinout compatibility and voltage level shifts when substituting these parts.
