Product details

Three-channel buffer with Schmitt-trigger inputs for noisy environments

The Texas Instruments SN74AUP3G17DQER is a triple non-inverting buffer from the 74AUP family, each channel with a Schmitt-trigger input for clean switching on slow or noisy edges. It operates from 0.8V up to 3.6V, making it suitable for battery-powered portable gear as well as core-logic level translation in mixed-voltage boards. The push-pull outputs sink and source 4mA each, enough to drive a few CMOS loads or a low-power LED through a series resistor, but not a relay coil or high-current bus. Packaged in an 8-X2SON measuring 1.4x1 mm, it fits tight layouts where every square millimetre counts.

Package reality — small footprint, careful assembly

The 8-X2SON (1.4x1 mm) is a leadless package with exposed pads underneath. It saves board area but demands a well-controlled reflow profile and post-solder inspection — not a hand-solder part. Plan for a solder-paste stencil with appropriate aperture ratio and X-ray inspection to confirm joint quality.

Lifecycle — active, no EOL concern

The 74AUP series remains a current portfolio family at Texas Instruments.

Frequently asked questions

What voltage does SN74AUP3G17DQER support?

The supply voltage range is 0.8V to 3.6V, covering single-cell battery operation up to standard 3.3V logic rails.

What is the equivalent of SN74AUP3G17DQER?

The closest functional peer is the SN74LVC2G17QDCKRQ1, also a Schmitt-trigger buffer but with two channels instead of three, a higher minimum supply (1.65V), and automotive qualification (AEC-Q100, -40°C to 125°C). It is not a pin-for-pin replacement — the package and channel count differ.
