Product details

Quad 5 V bus buffer with asymmetric drive

Each of the four elements handles one bit, delivering 32 mA output high and 64 mA output low — asymmetric drive that gives the low-side extra fan-out for driving heavily loaded buses or long backplane traces without external line drivers. Confirm your rail stays inside that window.

Package and mounting — 14-SOIC

Housed in a 14-SOIC package (0.209" body width, 5.30 mm) with a surface-mount footprint. The supplier device package is 14-SO. Tube shipment — not Tape & Reel — so factor that into your pick-and-place setup if you're feeding from tube feeders or need to transfer to tape for high-volume lines.

Frequently asked questions

What is the difference between SN74ABT125 and SN74ABT125NS?

The 'NS' suffix on SN74ABT125NS indicates the 14-SOIC (0.209", 5.30 mm width) surface-mount package variant. The base SN74ABT125 typically refers to the same die in a different package option (often a DIP or SOIC with a different body width). Functionally identical — the difference is the physical footprint and mounting method.

What is the propagation delay of SN74ABT125NS?

The evidence does not list a propagation delay value for this specific order code. For timing closure analysis, refer to the official Texas Instruments datasheet for the 74ABT125 family; typical propagation delays for the 74ABT series under 5 V operation are in the 3–5 ns range, but verify against the datasheet for your exact load and supply conditions.
