Product details

Quad buffer with 3-state outputs — 32 mA / 64 mA drive

The Texas Instruments SN74ABT125DR is a 74ABT-series quad buffer with non-inverting logic and 3-state outputs, packaged in a 14-SOIC (3.90 mm width) for surface-mount assembly. Each of the four elements handles one bit, with a combined output drive of 32 mA sourcing and 64 mA sinking — enough to drive a moderate backplane or a bank of LED indicators without external line drivers.

Industrial temperature and 5 V logic fit

If your design runs at 3.3 V, look at the 74LVC or 74AUC series instead — this part will not operate below 4.5 V.

Frequently asked questions

What is the difference between SN74ABT125DR and SN74LVC125A?

The LVC variant is the choice for 3.3 V or mixed-voltage buses; the ABT part is for 5 V-only rails where higher sink current is needed.
