Product details

It delivers push-pull output with 9mA source and sink capability, packaged in a 5-pin SOT-553. The Schmitt-trigger input provides hysteresis for noise-tolerant signal conditioning on slow or noisy edges, making it suitable for level translation, clock buffering, and sensor interface in battery-powered portable devices, IoT nodes, and low-voltage industrial control logic where the supply rail stays under 2.7V.

Supply voltage — the hard constraint

The 0.8V to 2.7V supply range is the defining spec for this buffer. It will not operate at 3.3V or 5V — the absolute maximum is 2.7V. If your design runs on a 1.8V or 2.5V rail, this part fits directly. For 3.3V systems, you need a different logic family such as the 74LVC or 74AHC series.

Industrial temperature and small footprint

The SOT-553 package measures roughly 1.6 mm x 1.6 mm, saving board space in dense layouts.

No direct second-source alternate is listed, but the 74AUC series is a standard TI logic family with broad distributor stocking.

Frequently asked questions

Can SN74AUC1G17DRLR be used at 3.3V?

No. The supply voltage range is 0.8V to 2.7V. Operating at 3.3V exceeds the absolute maximum rating and will damage the device. For 3.3V logic, use a 74LVC or 74AHC family buffer instead.

What is the equivalent to SN74AUC1G17DRLR?

There is no direct pin-compatible second source listed. For a dual-channel buffer with Schmitt-trigger input in a similar footprint, the SN74LVC2G17QDCKRQ1 (automotive grade, 1.65V to 5.5V) is a functional alternative but has different supply range and dual elements.
