Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify component authenticity through authorized distributors or TI directly. Confirm RoHS compliance status and lead finish specifications against current datasheets. Ensure storage conditions maintain moisture sensitivity level integrity prior to soldering.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when open-collector output capability is required for bus sharing or voltage translation. Compare propagation delay characteristics against system timing requirements. Verify pinout compatibility with existing PCB layouts before integration.

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. This distinction dictates specific circuit design considerations regarding load termination.
