Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or TI directly. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to your production timeline. Ensure proper ESD handling protocols are followed during storage and assembly to maintain device integrity.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when non-inverting octal transfer with open-collector outputs is required. Verify that the 74LS logic family speed and power consumption align with system constraints. Ensure the 20-pin SOIC footprint matches the PCB layout design specifications.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74LS64x family of octal bus transceivers. It shares functional similarities with the SN74LS640 but differs in output structure, utilizing open-collector rather than three-state outputs. The '1' suffix indicates non-inverting polarity, distinguishing it from inverting variants within the same series.
