Product details

No need to stockpile reels or worry about a sudden EOL notice on your BOM line.

The non-inverting path with 3-state output gives you a controlled disable for shared buses. Output drive is rated 32 mA for both high and low states — enough to light an LED directly or drive a short PCB trace to another logic input without a buffer stage.

No commercial-grade limitation here — it handles the thermal cycling of a motor drive or a rooftop controller without derating.

SOT-553 package — fits tight layouts

Housed in a 5-pin SOT-553, this buffer consumes minimal board area. The supplier device package is SOT-5, which is the same mechanical outline.

Frequently asked questions

What is the difference between SN74LVC1G126DRLR and SN74LVC1G126DBVR?

Both are the same single non-inverting buffer with 3-state output. The difference is the package: the DRLR suffix indicates SOT-553, while the DBVR suffix indicates SOT-23-5. The electrical specs — supply range, drive current, temperature grade — are identical. Choose the package that matches your PCB footprint.
