Product details
Overview
SN74AUP3G17DQER from Texas Instruments is a low-power triple Schmitt-trigger buffer IC in an 8-pin X2SON (DQE) package, operating from 0.8 V to 3.6 V supply. It delivers 5.1 ns max propagation delay at 3.3 V, 1.5 pF typical input capacitance, and 4.3 pF typical dynamic power dissipation-optimized for battery-powered portable systems requiring noise-immune signal conditioning.
For engineers reviewing the SN74AUP3G17DQER datasheet, SN74AUP3G17DQER pinout, SN74AUP3G17DQER application, or SN74AUP3G17DQER equivalent, key selection criteria include its Schmitt-trigger hysteresis (ΔVT = 0.79–1.31 V at 3 V), Ioff partial-power-down support, 3.6-V I/O tolerance for mixed-voltage interfacing, and ultra-low ICC of 0.9 µA max.
Technical Context
The SN74AUP3G17DQER implements three independent non-inverting Schmitt-trigger buffers with asymmetric input thresholds (VT+ and VT−), enabling robust noise rejection on slow or noisy digital signals. Its AUP-family architecture ensures stable operation across the full 0.8–3.6 V VCC range while maintaining sub-5 ns timing at 3.3 V.
Each buffer supports Ioff circuitry that disables outputs during partial power-down, preventing backflow current when VCC = 0 V. Input clamping and JESD 78 Class II latch-up compliance (≥100 mA) ensure reliability in industrial and portable environments with variable supply sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters |
| tpd Max | 5.1 ns at 3.3 V, CL = 15 pF - supports high-speed signal conditioning in point-to-point interconnects |
| ΔVT (Hysteresis) | 0.79–1.31 V at 3 V - rejects >1 V of input noise without false triggering |
| ICC Max | 0.9 µA at 25°C - extends battery life in always-on sensor nodes and wearables |
| Ci Typ | 1.5 pF - minimizes loading on high-impedance sources like crystal oscillators or analog comparators |
| Ioff Max | 0.6 µA at 0 V VCC - blocks damaging back-current during hot-insertion or multi-rail power sequencing |
| Cpd Typ | 4.3 pF at 3.3 V - reduces dynamic power consumption in high-frequency clock/data buffering |
Pinout & Package
X2SON-8 (DQE) package: 1.45 mm × 1.05 mm, 0.4 mm max height, exposed thermal pad, no leads, JEDEC MO-287 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input A1 | First Schmitt-trigger buffer input; accepts 0–3.6 V logic levels with hysteresis |
| 2 | Output Y1 | Non-inverting buffered output; drives loads up to ±4 mA at 3 V |
| 3 | Input A2 | Second Schmitt-trigger buffer input; electrically isolated from A1/Y1 |
| 4 | GND | Digital ground reference; must be connected to system ground plane for noise immunity |
| 5 | VCC | Supply voltage input; decoupling capacitor (0.1 µF) required within 2 mm |
| 6 | Output Y2 | Second non-inverting buffered output; shares VCC/GND with other channels |
| 7 | Input A3 | Third Schmitt-trigger buffer input; fully independent with identical threshold specs |
| 8 | Output Y3 | Third non-inverting buffered output; supports simultaneous switching with <10% VCC overshoot |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | VT+ = 2.29 V and VT− = 1.24 V at 3 V - eliminates chatter on slow-rising signals from mechanical switches or RC networks |
| Ioff partial-power-down | Enables safe isolation when VCC = 0 V - critical for USB/SD card hot-plug interfaces and multi-supply SoC subsystems |
| 3.6-V I/O tolerant | Accepts 3.6 V inputs while powered from 1.8 V - simplifies mixed-voltage signal routing without external translators |
| Ultra-low Ci | 1.5 pF typical - preserves signal integrity when buffering high-frequency clocks or RF control lines |
| Low-noise switching | Overshoot/undershoot <10% of VCC - prevents false triggering in adjacent sensitive analog or RF circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G17DQER | Higher ICC (max 10 µA), wider VCC range (1.65–5.5 V), no Ioff, higher Cpd (12 pF) | Better suited for 5 V legacy systems; lacks partial-power-down safety for modern multi-rail designs | Select only if 5 V compatibility is mandatory and Ioff is not required |
| SN74AUP2G17DQER | Dual-channel (not triple), identical AUP family specs: same VCC range, ICC, Ci, and ΔVT performance | Reduces channel count by one; suitable where only two buffered signals needed | Choose to save board space and cost when third buffer is unused |
Compared with SN74LVC3G17DQER, SN74AUP3G17DQER cuts static power by >90% and adds Ioff protection; versus SN74AUP2G17DQER, it provides a third independent channel without increasing footprint or supply current.

FAQ
What is the maximum operating temperature for SN74AUP3G17DQER?
The SN74AUP3G17DQER is rated for continuous operation from –40°C to +85°C ambient temperature. This range is validated per TI's recommended operating conditions and supported by thermal impedance data (θJA = 261°C/W for DQE package), making SN74AUP3G17DQER suitable for industrial and automotive cabin applications where thermal margins are constrained.
Does SN74AUP3G17DQER support mixed-voltage interfacing?
Yes, SN74AUP3G17DQER supports mixed-voltage interfacing via 3.6-V I/O tolerance: inputs accept voltages up to 3.6 V regardless of VCC (0.8–3.6 V), enabling direct connection to 3.3 V peripherals while powered from 1.8 V or lower rails-no external level shifters required for SN74AUP3G17DQER signal translation.
How does the Schmitt-trigger hysteresis of SN74AUP3G17DQER improve noise immunity?
SN74AUP3G17DQER provides programmable hysteresis (ΔVT = 0.79–1.31 V at 3 V) that creates distinct positive-going (VT+) and negative-going (VT−) input thresholds. This prevents oscillation on slow or noisy edges-such as those from mechanical switches or long traces-ensuring clean, chatter-free logic transitions without software debouncing for SN74AUP3G17DQER.
Can SN74AUP3G17DQER be used in partial-power-down configurations?
Yes, SN74AUP3G17DQER includes Ioff circuitry that actively disables all outputs when VCC = 0 V, limiting Ioff to 0.6 µA max. This prevents damaging back-current flow from live I/O pins into a powered-down system rail-making SN74AUP3G17DQER ideal for hot-plug interfaces like SD card slots or USB OTG detection circuits.
What is the typical input capacitance of SN74AUP3G17DQER and why does it matter?
SN74AUP3G17DQER has a typical input capacitance (Ci) of 1.5 pF. This ultra-low value minimizes loading on high-impedance signal sources-such as crystal oscillator outputs, analog comparator stages, or RF control lines-preserving signal rise time and reducing power loss, which directly benefits SN74AUP3G17DQER performance in precision timing and low-power sensing applications.
