Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix SSC against the manufacturer's current documentation to confirm pinout and package dimensions. Confirm that the component meets required automotive or industrial qualification standards if applicable. Check for obsolescence status as older Fairchild products may be discontinued or replaced by onsemi equivalents. Ensure compatibility with existing PCB footprints before procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when a 16-bit wide interface requires non-inverting buffering with high drive capability. The ACT logic family offers faster switching speeds compared to standard TTL while maintaining CMOS power efficiency. Verify that the system voltage aligns with the 4.5V to 5.5V operating range. Consider the 48-SSOP package constraints for board space and thermal management requirements during design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74ACT series of high-speed CMOS logic devices manufactured originally by Fairchild Semiconductor. The series provides performance comparable to Low-power Schottky TTL but with lower power consumption. The 16-bit configuration allows for parallel data handling, making it suitable for wide data buses in microprocessor systems and digital communication interfaces.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for the 74ACTQ16541 variant which shares similar functional characteristics. Verify if onsemi has released updated versions of this legacy Fairchild product. Ensure any substitute maintains the same 48-SSOP footprint and electrical specifications.
