Product details

Overview

74AUP3G14GNX from Nexperia is a low-power triple Schmitt trigger inverter IC in XSON8 (SOT1116) package, providing three independent hysteresis-equipped inverters for noise-immune signal conditioning. It operates from 0.8 V to 3.6 V, delivers ≤0.9 μA max ICC at 25 °C, supports IOFF partial power-down, and features input hysteresis (VH up to 1.31 V at VCC = 3.0 V) for clean edge regeneration in slow-rising waveforms - used in relaxation oscillators and pulse shaping in battery-powered sensor interfaces.

For engineers reviewing the 74AUP3G14GNX datasheet, 74AUP3G14GNX pinout, 74AUP3G14GNX application, or 74AUP3G14GNX equivalent, key selection criteria include supply voltage range (0.8–3.6 V), ultra-low static current (<1 μA), guaranteed IOFF behavior at VCC = 0 V, Schmitt trigger thresholds (VT+ = 2.32 V / VT− = 1.24 V at VCC = 3.0 V), and XSON8 thermal performance (4.2 mW/K derating above 90 °C).

Technical Context

This device implements three independent CMOS Schmitt-trigger inverters with asymmetric input thresholds (VT+ > VT−) to provide hysteresis, enabling robust conversion of slow or noisy analog-like signals into clean digital edges. Each inverter has rail-to-rail output swing and supports full I/O tolerance up to 3.6 V regardless of VCC.

The IOFF circuit actively disables outputs during power-down by disconnecting internal paths when VCC = 0 V, preventing backflow current and enabling live insertion in multi-rail systems. Propagation delay ranges from 1.5 ns (VCC = 3.0 V, CL = 5 pF) to 7.4 ns (VCC = 3.0 V, CL = 30 pF), with dynamic power dissipation governed by CPD = 4.3 pF.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	0.8 V to 3.6 V - enables direct interfacing with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters.
Max ICC (25 °C)	0.5 μA - ensures sub-microwatt static power in always-on sensor nodes and real-time clock supervisors.
Hysteresis Voltage VH	Up to 1.31 V at VCC = 3.0 V - rejects noise spikes ≥650 mV peak-to-peak on input lines.
IOFF Leakage	±0.75 μA at VCC = 0 V - prevents bus contention and cross-talk when upstream/downstream sections are powered off.
Propagation Delay	1.5 ns (min) to 7.4 ns (max) - supports timing-critical monostable multivibrator designs up to ~100 MHz effective toggle rate.
Input Voltage Range	−0.5 V to +4.6 V - allows safe connection to 5 V-tolerant signals while operating at 1.8 V VCC.
Operating Temperature	−40 °C to +125 °C - qualified for under-hood automotive and industrial motor control feedback paths.

Pinout & Package

XSON8 package (SOT1116): extremely thin small outline, no leads, 1.2 × 1.0 × 0.35 mm body, 8 terminals, wettable flank design for automated optical inspection.

Pin/Terminal	Circuit Role	Design Meaning
1	3A	Third inverter input - accepts standard CMOS/TTL logic levels; Schmitt-triggered for noise margin.
2	3Y	Third inverter output - rail-to-rail CMOS drive; sinks/sours ±4 mA at VCC = 3.0 V.
3	1Y	First inverter output - independently buffered; electrically isolated from other channels.
4	GND	Digital ground reference - must be connected before VCC to ensure proper IOFF activation.
5	2Y	Second inverter output - shares no internal nodes with 1Y or 3Y; supports parallel load driving.
6	2A	Second inverter input - identical electrical characteristics to 1A and 3A; fully interchangeable.
7	1A	First inverter input - pin 1 index located below marking code; used for clock input conditioning.
8	VCC	Supply voltage - powers all three inverters; IOFF activates automatically when VCC = 0 V.

Key Features

Feature	Design Value
Triple Schmitt trigger architecture	Three independent hysteresis inverters in one die - eliminates board space and BOM count vs. discrete solutions.
IOFF partial power-down	Output disable at VCC = 0 V with <±0.75 μA leakage - enables hot-swap capability in modular power systems.
Ultra-low ICC	≤1.4 μA max over −40 °C to +125 °C - extends battery life in coin-cell-powered IoT endpoints beyond 10 years.
Wide VCC range	0.8 V to 3.6 V operation - supports direct integration with energy-harvesting PMICs and low-voltage microcontrollers.
High noise immunity	Input hysteresis ≥0.79 V (VCC = 3.0 V) - rejects EMI-induced glitches on long PCB traces or flex cables.

Applications

Waveform Shaping

Astable Multivibrator

Use Scenario: Converting slow-rising analog sensor outputs (e.g., thermistor divider, photodiode amplifier) into clean square waves for MCU capture timers.

IC Role / Device Role / Timing Role: Signal conditioner and edge regenerator - transforms monotonic but noisy transitions into jitter-free digital pulses.

Use Value: Eliminates need for external RC filtering and comparator bias networks; reduces component count by ≥4 parts per channel.

Use Scenario: Generating precise clock signals in portable medical devices where crystal oscillators are cost- or size-prohibitive.

IC Role / Device Role / Timing Role: Core relaxation oscillator element - one inverter drives RC network, second provides feedback inversion.

Use Value: Achieves <±5% frequency stability over temperature using only two passive components; occupies <1.2 mm² PCB area.

Monostable Multivibrator

Power Sequencing Monitor

Use Scenario: Creating fixed-duration enable pulses for peripheral power rails (e.g., Wi-Fi module wake-up, display backlight strobe).

IC Role / Device Role / Timing Role: Pulse stretcher and noise-filtered trigger - converts short button press or interrupt into stable 10–100 ms output.

Use Value: Guarantees minimum pulse width even with contact bounce; immune to ESD transients on mechanical switch inputs.

Use Scenario: Validating correct power-up sequence across multiple voltage domains (e.g., 1.2 V core, 3.3 V I/O, 5 V analog) in FPGA-based systems.

IC Role / Device Role / Timing Role: Power-good logic gate - combines delayed reset signals via Schmitt inputs to generate synchronized system enable.

Use Value: Prevents metastability in multi-rail SoCs by enforcing strict sequencing windows; eliminates need for dedicated sequencer IC.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Schmitt trigger inverter applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G14DBVR	Wider VCC range (1.65–5.5 V); higher ICC (10 μA typ); no IOFF; SOT-23-5 package.	Requires level-shifting for sub-1.65 V systems; unsuitable for true zero-VCC isolation.	Select when interfacing with 5 V legacy peripherals and board space permits larger footprint.
74LVC3G14GM126	Same AUP family process but XQFN8 (SOT902-2); discontinued per Rev. 4 datasheet; not recommended for new designs.	No longer supported; no lifecycle assurance; no replacement cross-reference provided by Nexperia.	Avoid - use 74AUP3G14GNX for new designs requiring long-term supply continuity and validated thermal performance.

Compared with SN74LVC1G14DBVR, the 74AUP3G14GNX offers 20× lower static current and guaranteed IOFF, making it superior for battery-constrained and hot-swap applications; versus the obsolete 74LVC3G14GM126, it delivers identical functionality in a more manufacturable, inspected XSON8 variant with extended thermal derating data.

FAQ

Can 74AUP3G14GNX operate reliably at 0.8 V VCC with full logic functionality?

Yes - the device is fully specified down to 0.8 V VCC, with guaranteed VOH ≥ VCC − 0.11 V and VOL ≤ 0.50 V at −40 °C to +125 °C. Propagation delay remains functional (up to 19.9 ns at CL = 5 pF), and Schmitt thresholds scale linearly with VCC, ensuring consistent hysteresis behavior across the entire range.

What is the maximum capacitive load each output can drive while maintaining specified tpd?

Each output is characterized up to 30 pF load capacitance, with tpd ≤ 7.4 ns at VCC = 3.0 V. Driving >30 pF increases propagation delay nonlinearly and may cause overshoot/undershoot exceeding 10 % of VCC; for loads >50 pF, add series termination or buffer stage per Nexperia Application Note AN10862.

Does the IOFF feature require external pull-up/pull-down resistors on inputs or outputs?

No - IOFF is fully internal and activates automatically when VCC = 0 V. Inputs float with ≤±0.75 μA leakage; outputs enter high-impedance state without external bias. External resistors are unnecessary and may compromise noise immunity or increase standby current.

How does the 74AUP3G14GNX handle input voltages exceeding VCC, such as 3.6 V inputs at 1.8 V VCC?

It safely accepts input voltages up to 4.6 V (per Absolute Maximum Ratings), independent of VCC. Internal clamping diodes limit VI to GND − 0.5 V and VCC + 0.5 V, and IIK is limited to ±50 mA - enabling direct interface with 3.3 V or 5 V signals without external protection in mixed-voltage systems.
