Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'DW' corresponds to the SOIC-28 tube packaging configuration when ordering. Confirm RoHS compliance status as some variants may differ. Ensure the design accommodates the specified 4.5V to 5.5V supply voltage requirements. Check for any lead-free manufacturing updates or environmental declarations relevant to the current production batch before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal register with tri-state output capability is required for 5V logic systems. It is appropriate for designs needing high-speed data latching with minimal static power draw. Consider the SOIC-28 package constraints for PCB layout. Verify that the input voltage levels match the TTL compatibility specifications of the driving circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the Texas Instruments 74ACT series, which offers advanced CMOS technology for high-speed digital applications. The ACT series is designed to replace older LS/TTL logic families while providing lower power consumption and higher speed performance. It is widely used in industrial and consumer electronics where reliable 5V logic interfacing is necessary.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives within the same 74ACT family. Verify if the SN74ACT11821DR reel version meets packaging needs. Ensure substitute parts maintain the same 3-state output functionality and voltage specifications.
