Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix '1N' against the manufacturer's current datasheet to confirm pinout and electrical specifications, as variations exist within the ALS family. Ensure the procurement source provides valid RoHS compliance documentation if required by your assembly standards. Cross-reference the part number with official Texas Instruments catalogs to confirm current production status and availability constraints.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with built-in pull-ups is required for bus structures. The ALS series offers a balance of speed and power consumption superior to standard 74LS devices. Consider the PDIP-20 package constraints for PCB layout. Verify that the application voltage remains strictly within the 4.5 V to 5.5 V range to ensure reliable operation and prevent device damage.

Buffers, Drivers, Receivers, Transceivers Part Context

This component is part of the SN74ALSxxA family, representing Advanced Low-power Schottky technology. It serves as a successor to earlier 74Sxx and 74LSxx series devices, offering improved switching speeds while maintaining lower power dissipation. The octal buffer design allows for efficient management of multiple signal lines in complex digital systems without requiring external pull-up components.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct functional equivalents include the SN74ALS746DWR (SOIC-20) and SN74ALS746PW (TSSOP-20). For legacy compatibility, the SN74LS746 may be considered, though it lacks the integrated pull-up resistors and exhibits different electrical characteristics. Verify pinout compatibility before substituting packages.
