Product details

Quad buffer, 3-state, 5 V logic — what it does and where it fits

The Texas Instruments SN74ABT125D is a quad non-inverting buffer with 3-state outputs from the 74ABT family. Each of the four elements handles one bit. Supply range is 4.5 V to 5.5 V. Output drive is rated at 32 mA source, 64 mA sink.

Temperature grade and environment

Rated for -40°C to 85°C ambient, this buffer suits industrial control cabinets, telecom line cards, and general-purpose logic boards that see temperature swings but not extended automotive under-hood exposure. The 14-SOIC package is a standard surface-mount footprint, easy to place and reflow alongside other SOIC devices.

Lifecycle and sourcing

It is RoHS3 compliant, so it passes EU and other regulated-market requirements.

Frequently asked questions

Is SN74ABT125D RoHS compliant?

Yes, it is RoHS3 compliant — no lead or restricted substances above the exemption thresholds.

What is the difference between SN74ABT125D and SN74ABT125DW?

The difference is the package. SN74ABT125D is in a 14-SOIC (3.90 mm width) tube. SN74ABT125DW is in a 14-SOIC (7.50 mm width) — a wider body. The DW variant is also typically supplied in tape-and-reel. Functionally they are identical.

Is SN74ABT125D a direct replacement for 74ABT125 or other buffer ICs?

The SN74ABT125D is the standard 14-SOIC variant of the 74ABT125 quad buffer. It is a direct functional replacement for any 74ABT125 in the same package. For other buffer families (e.g. 74LVC, 74ACT), verify supply voltage and output drive compatibility — the 5 V supply and 32/64 mA drive differ from lower-voltage families.
