| FFF Compatibility | The SN74ABT240APWR shares the identical 20-pin TSSOP footprint and logical pin assignment, meaning it functions as a direct physical and logical drop-in replacement. Note that pin descriptions in the datasheet use 1-based indexing (1A1-1A4, 2A1-2A4) instead of 0-based indexing (1A0-1A3, 2A0-2A3), but the physical mappings are identical.Both parts are housed in a 20-pin TSSOP package with matching lead pitch, body width, and mounting dimensions.Meets or exceeds all electrical characteristics of the original part, including the 4.5V to 5.5V operating range and the ±32mA/64mA high-drive outputs. | Shares the exact same physical package layout and 20-pin TSSOP configuration, allowing it to fit onto the same board footprint. Pin numbering matches the logical connections.Standard 20-TSSOP package format is fully interchangeable.The 74ACT family uses CMOS technology rather than BiCMOS. While logic levels are TTL-compatible, the maximum output drive current is lower (±24mA source/sink compared to the original's +64mA/-32mA). This might be a limitation in heavily loaded bus-driving designs. | |
74ABT240PW by Nexperia: Buffer, Inverting 2 Element 4 Bit per Element 3-State Output 20-TSSOP. | The SN74ABT240APWR is the direct parametric equivalent and manufacturer-recommended replacement from Texas Instruments. It preserves the same high-drive BiCMOS logic family performance, making it the most reliable drop-in alternative for the obsolete NXP part.
| The onsemi 74ACT240MTCX is a high-speed CMOS alternative with TTL-compatible inputs. It is fully pin-compatible and ideal for designs that do not strictly require the extreme 64mA drive current of the original BiCMOS part.

You searched one part. Parter watches your whole BOM.
All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
