Product details
Overview
74AUP3G17GTX from Nexperia is a low-power triple Schmitt trigger buffer IC designed for signal conditioning in ultra-low-voltage digital systems. It provides three independent hysteresis-enabled buffers operating from 0.8 V to 3.6 V, with ICC ≤ 0.9 μA (max), VH ≥ 0.07 V (at VCC = 0.8 V), and tpd ≤ 3.6 ns (at VCC = 3.0 V, CL = 5 pF). It enables clean edge regeneration in battery-powered sensor interfaces and I²C bus level-shifting applications.
For engineers reviewing the 74AUP3G17GTX datasheet, 74AUP3G17GTX pinout, 74AUP3G17GTX application, or 74AUP3G17GTX equivalent, this page delivers verified electrical parameters, package-specific pin mapping, real-world use cases, and validated alternative options - all grounded in Nexperia's Rev. 4 (2023) product data sheet.
Technical Context
The 74AUP3G17GTX implements three independent Schmitt-trigger input stages with asymmetric VT+ and VT− thresholds, delivering input hysteresis (VH) from 0.07 V to 1.31 V across its 0.8–3.6 V supply range. Each buffer drives CMOS-compatible outputs with rail-to-rail VOH/VOL performance and supports IOFF partial power-down mode.
Its dynamic behavior is characterized by propagation delay (tpd) scaling inversely with VCC and load capacitance: 3.6 ns typical at 3.0 V/5 pF, degrading to 7.5 ns at 3.0 V/30 pF. Static power consumption remains stable (ICC ≤ 1.4 μA over −40 °C to +125 °C), and input leakage stays below ±0.75 μA across temperature and voltage ranges.
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. |
| ICC (max) | 0.9 μA at 25 °C - Ensures sub-1 μA static current draw for multi-year battery operation in IoT endpoints. |
| VH (min) | 0.07 V at VCC = 0.8 V - Provides noise margin against slow-rising signals in noisy industrial sensor nodes. |
| tpd (typ) | 2.7 ns at VCC = 3.0 V, CL = 5 pF - Supports >100 MHz signal edge regeneration in high-speed control loops. |
| IOFF Leakage | ±0.75 μA max at VCC = 0 V - Prevents backfeed current during partial system power-down in modular embedded designs. |
| ESD Rating | HBM > 5000 V, CDM > 1000 V - Sustains handling and board-level ESD events without functional degradation. |
| Operating Temp | −40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor drive control units. |
Pinout & Package
XSON8 package (SOT833-1): plastic extremely thin small outline, no leads, 8 terminals, body size 1.0 mm × 1.95 mm × 0.5 mm, thermal pad omitted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Input (Schmitt-triggered) | Three independent buffered inputs accepting up to 3.6 V regardless of VCC; enable mixed-voltage signal routing. |
| 1Y, 2Y, 3Y | Output (CMOS push-pull) | Three rail-to-rail outputs with VOH ≥ 2.6 V / VOL ≤ 0.44 V at VCC = 3.0 V, IO = ±4 mA. |
| VCC | Supply voltage | Single supply pin supporting 0.8–3.6 V; powers all three buffers and internal hysteresis circuitry. |
| GND | Ground reference | Common return path for supply and I/O; must be low-impedance to maintain noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 0.8 V to 3.6 V - Eliminates need for external regulators when interfacing with diverse SoC I/O banks. |
| IOFF partial power-down | Active at VCC = 0 V - Isolates powered subsystems from unpowered ones, preventing back-current damage in hot-swap systems. |
| Input hysteresis (VH) | 0.07 V to 1.31 V (VCC-dependent) - Rejects noise on slow analog-like signals (e.g., thermistor or potentiometer wipers). |
| Low dynamic noise | Overshoot/undershoot < 10 % of VCC - Reduces EMI and avoids false triggering in adjacent high-speed traces. |
| High noise immunity | VIH/VIL thresholds differ by VH - Guarantees reliable switching even with 200 mV of superimposed noise on input edges. |
Applications
| Industrial Sensor Interface | I²C Bus Level Translation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Wider VCC (1.65–5.5 V); higher ICC (10 μA typ); no IOFF; VH ≈ 0.3 V at 3.3 V | Not suitable for sub-1.2 V systems or partial power-down architectures | Select when interfacing legacy 5 V peripherals and higher drive strength (>32 mA) is required. |
| 74LVC1G17GW,125 | Same VCC range (1.65–5.5 V); no IOFF; VH ≈ 0.25 V at 3.3 V; SOT353 (5-pin) package | Lacks power-down isolation; incompatible pinout; unsuitable for ultra-low-IQ designs | Choose only if footprint compatibility with existing LVC-family layouts is mandatory and IOFF is not needed. |
Compared with SN74LVC1G17DBVR and 74LVC1G17GW,125, the 74AUP3G17GTX uniquely supports 0.8 V operation and IOFF - critical for energy harvesting and modular power-gating systems where other alternatives fail to meet quiescent current or voltage-range requirements.

FAQ
What is the maximum input voltage the 74AUP3G17GTX can tolerate when VCC = 0.8 V?
The device accepts input voltages up to 3.6 V regardless of VCC level, as confirmed in Section 2 ("Inputs accept voltages up to 3.6 V") and Table 5 (VI absolute max = +4.6 V). This allows safe interfacing with higher-voltage signals in mixed-supply systems without clamping diodes or resistive dividers.
Does the 74AUP3G17GTX support true bidirectional level shifting?
No - it is a unidirectional buffer with Schmitt-trigger inputs and CMOS outputs. For I²C bidirectional translation, two gates per line are used in open-drain configuration with external pull-ups, relying on hysteresis to stabilize transitions. True bidirectional level shifters (e.g., TXB0108) require different architecture.
How does the IOFF feature behave during partial power-down?
When VCC = 0 V, the IOFF circuit disables all three outputs, limiting back-current to ±0.75 μA max (Table 7). This prevents current flow from live inputs (e.g., 3.3 V sensors) into the unpowered IC, protecting both the device and upstream circuitry in modular power architectures.
Can the 74AUP3G17GTX replace standard 74HC14 hex inverters in low-power designs?
Only one gate at a time - the 74AUP3G17GTX contains three non-inverting Schmitt buffers, not inverters. Its lower ICC (0.9 μA vs. ~2 μA for HC14), wider VCC (0.8 V vs. 2 V min), and IOFF make it superior for ultra-low-power non-inverting signal conditioning, but functional replacement requires redesigning logic polarity.
