Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'N3' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the procurement source provides genuine Texas Instruments components to avoid counterfeit risks. Check for RoHS compliance status if required by your manufacturing standards. Confirm the package type is indeed 20-PDIP as specified.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed inverting buffering is required for 5V logic systems. The Schottky technology offers a balance between speed and power consumption compared to standard TTL. Consider the three-state output capability if multiple devices share a common data bus. Verify that the through-hole packaging suits your PCB assembly process.
