Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the E4 suffix indicates lead-free composition and RoHS compliance when sourcing. Confirm the TSSOP-24 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your specific environmental constraints. Check for any specific tape and reel specifications required for automated assembly processes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring registered data latching alongside bus driving capabilities. The LVC series offers lower power consumption compared to older logic families. Verify that the 1.65 V to 3.6 V supply range aligns with your system's voltage rails. Consider the 8 ns propagation delay for timing analysis in your signal paths.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC543A family of octal bus transceivers. The E4 suffix typically denotes lead-free packaging compliant with international environmental standards. It is categorized under CMOS logic integrated circuits designed for general-purpose digital applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

SN74LVC543APWR is the standard commercial version without the E4 suffix. SN74ABT543APWR offers higher drive current but requires a 5 V supply. SN74LVCR2245APWRE4 provides similar functionality but lacks the registered feature.
