Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the exact package type against the datasheet, as the APW suffix typically denotes TSSOP-20 but cross-reference with official TI documentation to confirm pinout and thermal characteristics. Ensure the order matches the required logic family specifications and check for RoHS compliance status in the latest manufacturer release notes before finalizing procurement.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring octal buffering with inverting functionality at 5V logic levels. The ABT series offers improved speed compared to standard TTL while maintaining compatible input/output characteristics. Consider the 5.1 ns propagation delay for timing-critical paths and ensure the PCB layout accommodates the specific package dimensions and thermal requirements for the intended operating environment.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the SN74ABT2240A family of octal buffers and line drivers. It shares functional similarities with other ABT series components like the SN74ABT244A, though it differs in polarity and specific drive capabilities. The ABT technology combines advanced silicon gate CMOS with BiCMOS to achieve high-speed performance suitable for demanding digital interface applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes may include SN74ABT2240ADW (SOIC-20) or SN74ABT2240AN (PDIP-20), provided the package footprint allows adaptation. Verify that alternative packages maintain identical electrical characteristics and pin compatibility if board space permits modification.
