Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition and RoHS compliance as per manufacturer standards. Confirm the TSSOP-20 package dimensions match the target PCB footprint. Ensure the operating temperature range meets system requirements. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an inverting octal buffer with tri-state control is required. The ABT series offers faster switching speeds compared to standard ALS logic. Consider the -32 mA source and 12 mA sink currents for load matching. Verify that the 4.5 V to 5.5 V supply range aligns with the system power rails.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ABT2240A series of octal buffers and line drivers. It is functionally similar to non-inverting variants like the SN74ABT244A but provides inverted outputs. The E4 suffix typically denotes environmental compliance. It serves as a high-performance solution for digital signal routing in industrial and commercial equipment.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

The SN74ABT2240ADWR is a tube-packaged equivalent with identical electrical characteristics. For non-inverting applications, the SN74ABT244A series may be considered if polarity inversion is not required. Verify package compatibility when substituting SOIC variants for TSSOP.
