Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-24 package variant during procurement. Ensure the component meets RoHS compliance requirements as indicated in official documentation. Confirm that the LVC series specifications align with the target system's voltage and timing constraints before finalizing orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal registered transceiver is required for low-voltage applications between 1.65 V and 3.6 V. The LVC series offers improved performance over standard CMOS while maintaining compatibility with LVTTL logic levels. Consider the TSSOP-24 package for surface-mount assembly needs.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC543A series of octal registered transceivers. It is distinct from unregistered variants like the SN74LVC540 and differs from other logic families such as ABT or LVTH which operate at different voltage ranges or offer varying speed characteristics. The LVC series is optimized for low-power consumption in portable applications.
