Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix FG against official datasheets to confirm package type and tape/reel specifications. Ensure compatibility with required operating temperatures and voltage ranges. Cross-reference pinout assignments with legacy LS244 designs if used as a drop-in replacement. Confirm RoHS compliance status through manufacturer documentation prior to integration.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state outputs is required for 5V logic systems. It serves as a functional equivalent to LS244 devices but utilizes HCT CMOS technology. Consider the SOEIAJ-20 package constraints for PCB layout. Verify input/output current requirements match the load characteristics of the destination circuitry.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the MC74HCT244A series of buffers and line drivers from onsemi. The series is designed for high-speed digital applications requiring multiple buffered channels. It falls under the broader category of logic ICs, specifically within the buffer and line driver subcategory for CMOS logic families.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The datasheet states the MC74HCT244A is identical in pinout to the LS244. This allows for potential direct pin-compatible substitution in existing designs utilizing the LS244, provided voltage and speed requirements are met.
