Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer designation and package type against current datasheets, as component availability may vary across different production eras. Confirm RoHS compliance status and ensure the pinout matches the intended PCB footprint before finalizing procurement decisions.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed octal buffering with strong drive currents is required. It serves as a suitable alternative to standard logic families needing improved switching performance and lower power dissipation while maintaining compatibility with CMOS interfaces in high-density digital systems.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the ABT (Advanced BiCMOS Technology) family, which combines the speed of bipolar technology with the low power consumption of CMOS. It is functionally related to other octal buffers like the 74AC244 but offers enhanced drive strength and switching characteristics suitable for demanding bus applications.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for equivalents such as the SN74ABT244 from Texas Instruments or the MC10ABT244 from ON Semiconductor. Ensure that any substitute maintains the same 20-pin SSOP package and electrical characteristics to guarantee direct pin-to-pin compatibility without circuit modification.
