Product details

Single-bit buffer with Schmitt-trigger input for noise-prone rails

The Texas Instruments SN74AUP1G17DBVR is a single non-inverting buffer from the 74AUP low-power logic family. Its Schmitt-trigger input provides clean switching even on slow or noisy signal edges, making it a natural choice for debouncing pushbuttons, conditioning sensor outputs, or squaring up oscillator signals in battery-powered and portable gear. Housed in a 5-pin SOT-23-5, the part occupies minimal board area while remaining hand-solderable for prototype rework.

Supply voltage and temperature — fit for industrial and portable designs

It is not intended for heavy fan-out or line driving.

For dual-sourcing flexibility, the SN74LVC2G17QDCKRQ1 is a functionally similar dual buffer with automotive AEC-Q100 qualification and a wider temperature range (-40°C to 125°C), but it operates from a 1.65 V minimum supply and comes in a different footprint — verify the pinout before substituting.

This saves two passives and a board via per channel.

Frequently asked questions

Is SN74AUP1G17DBVR active or obsolete?

The SN74AUP1G17DBVR is listed as Active by Texas Instruments with ROHS3 compliance. No end-of-life notice or last-time-buy date has been issued, so it remains a safe choice for new designs.

What is the difference between SN74AUP1G17 and SN74LVC1G17?

The SN74AUP1G17 operates down to 0.8 V, while the SN74LVC1G17 has a minimum supply of 1.65 V. Both offer Schmitt-trigger inputs and similar output drive, but the AUP variant is the choice for sub-1.8 V rails. Package and pinout are the same in the SOT-23-5 case.

Can I use SN74AUP1G17DBVR as a replacement for SN74AUP1G17DBVT?

The SN74AUP1G17DBVR and SN74AUP1G17DBVT share the same die and electrical specifications. The difference is the shipping medium: DBVR is Tape & Reel, DBVT is Cut Tape. For a one-to-one functional replacement on the board, yes — the part is identical.
