Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer origin, as Fairchild Semiconductor operations were acquired by onsemi. Confirm that the 74ABT2244CSC designation aligns with current onsemi product lines or legacy Fairchild stock. Ensure the SOP-20 package variant matches the required PCB footprint. Check RoHS compliance status against the specific manufacturing date code. Validate availability through authorized distributors given potential lifecycle changes.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring high-speed unidirectional buffering with strong drive capabilities. The ABT series offers superior switching speed compared to standard AC/ACT families while maintaining CMOS power efficiency. Ensure the design accommodates the 4.5V to 5.5V supply requirement. Consider the 20-SOP package constraints for thermal management and board space. Verify that the three-state enable logic levels are compatible with the system's control signals.

Buffers, Drivers, Receivers, Transceivers Part Context

The 74ABT2244CSC belongs to the widely adopted 74ABT logic family, which bridges the performance gap between older Schottky TTL and newer CMOS technologies. This specific part number represents the octal buffer variant, distinct from the bidirectional transceiver versions like the 2245. The 'CSC' suffix typically denotes the SOP-20 plastic surface-mount package. It serves as a critical interface component in digital systems requiring signal isolation and amplification.
