Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix 'DLR' corresponds to the tape-and-reel packaging configuration, as this affects handling and assembly processes. Confirm that the active status aligns with long-term availability requirements. Ensure compatibility with existing PCB footprints designed for the 48-SSOP package dimensions. Cross-reference the manufacturer's latest documentation for any recent design or lifecycle updates.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when 16-bit unidirectional buffering with high drive strength is required. The ACT series offers speed comparable to LS TTL but with CMOS power consumption. Verify that the 4.5 V to 5.5 V supply voltage matches the system architecture. Consider the 48-SSOP package constraints regarding thermal dissipation and board space compared to other available packages.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT logic family, which bridges the performance gap between standard TTL and CMOS technologies. It is designed for high-speed digital applications where noise immunity and low power are critical. The 16240 variant specifically addresses the need for wide data path buffering in complex digital systems.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The 74ACT16240DL is a tube-packaged equivalent from Texas Instruments. The 74ACTQ16240MTD from onsemi serves as a functional alternative, though it is noted as obsolete.
