Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'W' indicates the TSSOP-24 package configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure voltage supply ranges align with system requirements of 1.65 V to 3.6 V. Check for any recent product change notifications regarding pinout or electrical characteristics updates.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring eight-bit registered data transfer in low-voltage environments. Compare against standard unregistered transceivers if latching functionality is necessary. Consider the 8 ns propagation delay for timing-critical paths. Evaluate thermal performance within the specified operating temperature range during PCB layout.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LVC543A series of octal bus transceivers. It is functionally similar to the SN74LVC543APWR but differs in packaging format. The LVC series provides wide operating voltage ranges suitable for mixed 5-V and 3.3-V systems. It serves as a registered interface between microprocessors and peripheral devices.
