Is there a pin-compatible replacement for SN74LVC1G125DBVR?

This analysis did not identify a verified pin-compatible replacement. Candidates with similar part numbers from other vendors should be checked for identical pinouts, especially the location of the Output Enable (OE) pin.

What risks should I check before replacing SN74LVC1G125DBVR?

Verify the package (SOT-23-5), pinout (A, Y, OE, VCC, GND), logic function (non-inverting buffer), output type (3-state), supply voltage (1.65V-5.5V), and temperature range (-40°C to 125°C).

SN74LVC1G125DBVR Alternatives, Datasheet & Cross Reference | Texas Instruments

SN74LVC1G125DBVR is a single non-inverting buffer gate with a 3-state output. Finding a direct replacement requires careful matching of the 3-state function and pinout.

AI replacement insight

Electrical riskhigh

Output type (Open-Drain vs 3-State) and pinout mismatch are critical functional differences.

Package risklow

SOT-23-5 is a common package, so physical fit is not a primary concern.

Can it be replaced directly?

No direct, pin-compatible replacements were found in this analysis. Alternatives like the SN74LVC1G07DBVR have a different output type (open-drain) and pinout, requiring circuit modification.

Best replacement path

Search for other single non-inverting buffers with 3-state outputs in a SOT-23-5 package, ensuring the pinout for input, output, and output enable (OE) match.

Main risk

The primary risk is mismatching the output stage; replacing a 3-state output with an open-drain or standard push-pull output will likely cause circuit failure.
