The Texas Instruments SN74ABT2240APWLE is a 4-bit bus driver from the ABT (Advanced BiCMOS Technology) logic family. It is designed for high-speed, low-power bus driving in digital systems, commonly used in backplane or memory-interface applications where signal integrity and drive strength matter. The ABT series offers a balance of speed and output current that suits 5 V and mixed-voltage logic environments.
No last-time-buy or obsolescence risk is associated with this part at present. However, it is listed as RoHS non-compliant, which is a critical factor for designs that must meet EU RoHS or similar lead-free directives. If your assembly process requires lead-free solder, you will need to evaluate exemptions or consider a RoHS-compliant alternate within the ABT family.
This part is — typically tubes or trays, not tape-and-reel. For automated pick-and-place lines, verify that your feeder setup can accommodate tube-fed devices, or plan for manual placement.
