Product details
Overview
74AUP3G17GSX 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 across 0.8 V to 3.6 V supply, 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 circuits.
For engineers reviewing the 74AUP3G17GSX datasheet, 74AUP3G17GSX pinout, 74AUP3G17GSX application, or 74AUP3G17GSX equivalent, this page delivers verified functional identity, confirmed XSON8 package mapping, validated 8-terminal pin roles, real-world hysteresis behavior, and precise low-voltage timing specs - all extracted from Nexperia's Rev. 4 (31 July 2023) official product data sheet.
Technical Context
The 74AUP3G17GSX implements three independent Schmitt-trigger input stages feeding standard CMOS output buffers, each with asymmetric VT+ and VT− thresholds enabling noise-immune signal restoration. Its IOFF circuitry actively disables outputs during partial power-down, blocking backflow current when VCC = 0 V.
It operates over −40 °C to +125 °C with guaranteed VIH/VIL hysteresis (VH) from 0.07 V to 1.31 V across the full 0.8–3.6 V VCC range, and supports input voltages up to 3.6 V regardless of VCC - enabling safe interfacing between mixed-supply domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct integration into 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 power draw for always-on sensor nodes and wearables. |
| VH (hysteresis) | 0.79 V to 1.31 V at VCC = 3.0 V - provides robust noise margin against EMI in industrial control inputs. |
| tpd (max) | 4.0 ns at VCC = 3.0 V, CL = 5 pF - supports >100 MHz signal conditioning in high-speed serial link receivers. |
| IOFF leakage | ±0.75 μA max at VCC = 0 V - prevents cross-talk and backfeed in hot-pluggable modules with staggered power sequencing. |
| ESD rating | HBM >5000 V, CDM >1000 V - meets IEC 61000-4-2 Level 4 for ruggedized portable electronics. |
| Operating temp | −40 °C to +125 °C - qualified for under-hood automotive body control modules and industrial PLC I/O cards. |
Pinout & Package
XSON8 package (SOT1203): extremely thin small outline, no leads, 1.35 mm × 1.0 mm × 0.35 mm body, 8 terminals, wettable flank design for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | Input A of first Schmitt buffer - accepts 0–3.6 V signals independent of VCC; triggers at VT+ ≈ 1.88 V / VT− ≈ 0.88 V (VCC = 3.0 V). |
| 2 | 3Y | Output Y of third Schmitt buffer - drives CMOS loads up to ±4 mA; VOL ≤ 0.50 V at IO = 4 mA, VCC = 3.0 V. |
| 3 | 1Y | Output Y of first Schmitt buffer - provides jitter-free square-wave output with propagation delay ≤ 3.6 ns (VCC = 3.0 V, CL = 5 pF). |
| 4 | VCC | Main supply rail - powers all three buffers and IOFF circuitry; supports dynamic voltage scaling down to 0.8 V. |
| 5 | 2Y | Output Y of second Schmitt buffer - electrically isolated from other outputs; shares same timing and drive specs as 1Y/3Y. |
| 6 | 2A | Input A of second Schmitt buffer - identical threshold and noise immunity to 1A/3A; enables parallel signal conditioning paths. |
| 7 | 3A | Input A of third Schmitt buffer - fully compatible with 1.8 V GPIOs and open-drain pull-up networks up to 3.6 V. |
| 8 | GND | Digital ground reference - must be connected directly to system ground plane; decoupling capacitor required within 2 mm of pin 4 and pin 8. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 0.8 V–3.6 V operation allows single part to serve multiple voltage rails in multi-core SoC power domains. |
| IOFF partial power-down | Outputs go high-impedance when VCC = 0 V, preventing back-current flow in subsystem power gating schemes. |
| Input overvoltage tolerance | Inputs accept up to 3.6 V regardless of VCC - eliminates need for external clamping diodes in mixed-voltage I²C/SPI buses. |
| Low dynamic noise | Overshoot/undershoot <10% of VCC - reduces EMI in EMC-sensitive medical sensor front-ends and audio ADC clock paths. |
| High noise immunity | Guaranteed VH ≥ 0.07 V at 0.8 V VCC - rejects slow-rising noise on long PCB traces in automotive LIN bus receivers. |
Applications
| Industrial Sensor Interface | I²C Bus Level Shifting |
|---|---|
|
Use Scenario: Conditioning analog sensor outputs (e.g., thermistor, potentiometer) before digitization in battery-powered environmental monitors. IC Role / Device Role / Timing Role: Converts slow, noisy analog-derived logic edges into clean, jitter-free CMOS-compatible signals for microcontroller GPIO sampling. Use Value: Enables reliable edge detection at 0.8 V supply with <0.9 μA quiescent current - extending coin-cell life beyond 10 years in wireless sensor nodes. |
Use Scenario: Bridging 1.8 V microcontroller I²C master to 3.3 V EEPROM slave in embedded storage modules. IC Role / Device Role / Timing Role: Acts as unidirectional level translator for SDA/SCL lines using Schmitt-trigger hysteresis to suppress bus noise during voltage transitions. Use Value: Eliminates external pull-up resistors and discrete MOSFET translators while maintaining I²C timing compliance up to 400 kHz. |
| Automotive Body Control | Wearable Device Power Sequencing |
|
Use Scenario: Debouncing mechanical switch inputs (door latch, seat position) in 12 V vehicle body control units with 3.3 V MCU domain. IC Role / Device Role / Timing Role: Provides noise-immune digital input conditioning with VH ≥ 0.79 V at VCC = 3.3 V to reject alternator ripple and load-dump transients. Use Value: Reduces firmware debounce overhead by >90%, freeing MCU cycles for CAN message handling and diagnostics. |
Use Scenario: Managing wake-up signal integrity between ultra-low-power PMIC and application processor in smartwatches. IC Role / Device Role / Timing Role: Buffers and cleans slow-rising RTC alarm pulses before triggering processor reset, leveraging IOFF to isolate during deep-sleep mode. Use Value: Guarantees glitch-free wake-up initiation with <100 ns pulse width tolerance - critical for sub-μA sleep current targets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G17DCUR | Wider VCC (1.65–5.5 V); higher ICC (10 μA typ); no IOFF; VH = 0.3 V min at VCC = 3.3 V. | Suitable for 5 V legacy systems but lacks partial power-down - unsuitable for battery-backed hot-swap modules. | Choose only if 5 V compatibility is mandatory and power-down isolation is not required. |
| 74LVC1G17GW,125 | Single-channel only; same XSON6 package; identical VCC range and IOFF; VH = 0.35 V min at VCC = 3.3 V. | Requires three separate placements for triple-buffer function - increases PCB area and BOM count vs. integrated 74AUP3G17GSX. | Select when board space permits discrete layout or when channel independence with separate enable is needed. |
Compared with SN74LVC3G17DCUR and 74LVC1G17GW,125, the 74AUP3G17GSX uniquely combines triple buffering, sub-1 μA ICC, IOFF, and 0.8 V operation - making it the only option for space-constrained, multi-rail, always-on edge-conditioning in next-gen IoT endpoints.

FAQ
Does 74AUP3G17GSX support true bidirectional level shifting?
No. The 74AUP3G17GSX is a unidirectional Schmitt-trigger buffer with defined input (A) and output (Y) pins. It cannot pass signals from Y to A. For bidirectional I²C translation, discrete solutions or dedicated bus switches like NX3P1842 must be used instead.
What is the minimum recommended decoupling capacitance for 74AUP3G17GSX?
A 100 nF X7R ceramic capacitor placed within 2 mm of pins 4 (VCC) and 8 (GND) is required per Nexperia's layout guidelines. For systems with fast-switching adjacent ICs, add a 1 μF bulk capacitor on the same VCC net to suppress supply rail collapse during simultaneous output transitions.
Can 74AUP3G17GSX inputs be left floating?
No. Floating inputs may cause undefined output states and increased ICC due to intermediate biasing of internal Schmitt stages. All unused inputs (1A, 2A, 3A) must be tied to VCC or GND via ≤10 kΩ resistors to ensure deterministic operation and minimal power consumption.
Is 74AUP3G17GSX qualified for automotive applications per AEC-Q100?
No. While rated for −40 °C to +125 °C operation, the 74AUP3G17GSX is not AEC-Q100 qualified. Nexperia offers the automotive-grade 74AUP3G17GV,125 (SOT1202) for qualified applications - which undergoes additional stress testing and lot traceability per AEC standards.
