Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer marking matches National Semiconductor specifications. Confirm the package type is 20-SOIC with the specified width. Check for RoHS compliance status if required by your assembly process. Ensure the part number suffix 'X' aligns with your reel or tube requirements. Cross-reference the datasheet revision date to confirm technical parameters.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with three-state outputs is required for bus applications. Consider the FCT series compatibility with existing TTL or CMOS logic families. Evaluate the 20-SOIC package size against board space constraints. Verify that the 5.25V maximum supply voltage meets system power requirements. Assess the need for non-inverting functionality versus other logic types.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74FCT family of high-speed CMOS logic devices. It serves as a direct replacement for older 74LS244 designs in many applications due to improved speed and lower power. The FCT series is known for its compatibility with standard TTL inputs while offering CMOS performance characteristics. It is widely used in computer and communication equipment requiring reliable signal buffering.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for pin-compatible alternatives from other manufacturers such as ON Semiconductor MM74HC244N, noting differences in supply voltage ranges and speed characteristics. Verify that substitute parts maintain the same 20-pin SOIC package and three-state output functionality. Ensure logical equivalence in terms of non-inverting behavior and bit count.
