Product details

Overview

74AUP2G14GX from Nexperia is a dual Schmitt-trigger inverter IC operating from 0.8 V to 3.6 V supply, delivering ultra-low static current (≤1.4 μA at −40 °C to +125 °C), input hysteresis (up to 1.31 V at 3.0 V), and IOFF-enabled partial power-down protection. It serves as a noise-immune signal conditioner in low-power sensor interfaces and timing circuits.

For engineers reviewing the 74AUP2G14GX datasheet, 74AUP2G14GX pinout, 74AUP2G14GX application, or 74AUP2G14GX equivalent, key selection criteria include its 6-terminal X2SON6 package (SOT1255-2), −40 °C to +125 °C temperature rating, Schmitt-trigger threshold stability across voltage rails, and IOFF leakage < ±0.75 μA during power-down.

Technical Context

This device implements two independent CMOS inverters with Schmitt-trigger inputs-each featuring asymmetric positive-going (VT+) and negative-going (VT−) thresholds that create voltage hysteresis (VH) up to 1.31 V at VCC = 3.0 V. Thresholds scale predictably with supply voltage (e.g., VT+ = 1.88 V, VT− = 0.88 V at 3.0 V).

The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ≤±0.75 μA and enabling safe hot-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 Range	0.8 V to 3.6 V - supports direct interfacing with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters
Max ICC (Static)	1.4 μA at −40 °C to +125 °C - enables decade-long battery life in always-on IoT endpoints
Hysteresis Voltage (VH)	Up to 1.31 V at VCC = 3.0 V - rejects >1.3 V of noise on slow-rising signals in industrial sensor lines
IOFF Leakage	±0.75 μA at VCC = 0 V - prevents bus contention and latch-up during partial system shutdown
Propagation Delay	1.5 ns to 7.4 ns (VCC = 3.0 V, CL = 5–30 pF) - suitable for sub-100 MHz clock conditioning and pulse shaping
Input Overvoltage Tolerance	3.6 V - allows safe connection to 3.3 V signals even when VCC = 1.2 V
ESD Rating	HBM >5000 V, CDM >1000 V - survives handling and board-level ESD events without shielding

Pinout & Package

X2SON6 plastic thermal enhanced extremely thin small outline package (SOT1255-2); no leads; 6 terminals; body dimensions 1.0 mm × 0.8 mm × 0.32 mm; thermal pad exposed on bottom for improved heat dissipation.

Pin/Terminal	Circuit Role	Design Meaning
1	2A	Second inverter input - accepts Schmitt-triggered logic levels; tolerant to 3.6 V regardless of VCC
2	1A	First inverter input - identical electrical behavior to Pin 1; enables dual independent signal conditioning
3	2Y	Second inverter output - drives capacitive loads up to 30 pF with <7.4 ns delay at 3.0 V
4	GND	Digital ground reference - must be connected to system ground plane; shared return for both inverters
5	VCC	Supply voltage input - powers both inverters; IOFF activates automatically when pulled to 0 V
6	1Y	First inverter output - complements 1A with hysteresis; used for feedback in relaxation oscillators

Key Features

Feature	Design Value
Ultra-low power operation	ICC ≤ 1.4 μA over full temperature range - eliminates need for power gating in energy-harvesting nodes
Schmitt-trigger input hysteresis	VH = 0.79–1.31 V depending on VCC - converts noisy analog-like edges into clean digital transitions
IOFF partial power-down	Output disable at VCC = 0 V with <±0.75 μA leakage - enables live insertion into powered backplanes
Overvoltage-tolerant inputs	VI max = 3.6 V independent of VCC - simplifies mixed-voltage interconnect without external clamps
Wide temperature operation	Specified from −40 °C to +125 °C - qualified for under-hood automotive and industrial control environments

Applications

Waveform Shaping

Astable Multivibrator

Use Scenario: Converting slow-rising analog sensor outputs (e.g., thermistor divider, photodiode amplifier) into rail-to-rail digital pulses for microcontroller GPIO capture.

IC Role / Device Role / Timing Role: Dual Schmitt-trigger inverter providing noise-immune signal squaring and edge sharpening.

Use Value: Eliminates external RC filtering and reduces firmware debouncing overhead by >90% in battery-powered environmental monitors.

Use Scenario: Generating continuous square-wave clock signals for LED blinkers, status indicators, or low-frequency test clocks in portable diagnostics tools.

IC Role / Device Role / Timing Role: Cross-coupled inverter pair forming a self-oscillating relaxation oscillator with resistor-capacitor timing network.

Use Value: Requires only one external capacitor and two resistors; achieves stable 1–10 kHz oscillation without quartz or dedicated timer ICs.

Monostable Multivibrator

Power Sequencing Control

Use Scenario: Creating precise, single-shot timing pulses (e.g., 10–100 ms) to trigger reset sequences, enable delays, or gate power to peripherals after wake-up.

IC Role / Device Role / Timing Role: Inverter-based edge-triggered monostable using RC differentiator and feedback path.

Use Value: Delivers jitter-free pulse widths with <5% variation across voltage/temperature; replaces discrete transistor timers with 70% board space reduction.

Use Scenario: Managing startup order of multiple voltage rails (e.g., 1.2 V core before 3.3 V I/O) in FPGA or SoC carrier boards where sequencing margin is tight.

IC Role / Device Role / Timing Role: Inverter with IOFF used as a controlled enable switch - output disabled until VCC stabilizes, then asserts downstream enable signal.

Use Value: Prevents backfeed through unpowered regulators; ensures strict monotonic ramp-up without external supervisor ICs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC2G14DSFR	Wider VCC range (1.65–5.5 V); higher ICC (max 10 μA); no IOFF; SOT-23-6 package	Not suitable for sub-1.65 V operation or partial power-down systems	Select when interfacing with 5 V logic or when IOFF is unnecessary and cost is primary
74LVC2G14GW,125	Same SOT363-2 package; VCC = 1.65–5.5 V; ICC ≤ 10 μA; no IOFF; lower hysteresis (VH ≈ 0.3 V at 3.3 V)	Lacks robust noise immunity below 2 V and cannot support hot-swap architectures	Choose for legacy TSSOP6 footprint compatibility where 3.3 V-only operation suffices

Compared with SN74LVC2G14DSFR and 74LVC2G14GW,125, the 74AUP2G14GX uniquely supports 0.8 V operation, delivers 5× lower static current, provides IOFF for system-level power management, and offers 4× greater hysteresis-making it optimal for ultra-low-power, mixed-voltage, and hot-plug-sensitive designs.

FAQ

What is the maximum load capacitance supported while maintaining guaranteed propagation delay?

The datasheet specifies propagation delay performance up to 30 pF load capacitance across all VCC conditions (0.8 V–3.6 V). At VCC = 3.0 V, tpd remains ≤7.4 ns with CL = 30 pF. Driving larger capacitive loads may increase delay unpredictably and is not characterized.

Can 74AUP2G14GX be used with VCC = 0 V while other system rails remain active?

Yes - the IOFF feature actively disables both outputs when VCC = 0 V, limiting leakage to ±0.75 μA. This prevents back-current flow into the device and avoids bus contention, making it safe for use in partial-power-down scenarios like hot-swap card slots.

How does the Schmitt-trigger hysteresis vary with supply voltage?

Hysteresis voltage (VH = VT+ − VT−) scales with VCC: it is 0.07 V at 0.8 V, 0.46 V at 1.1 V, 0.56 V at 1.4 V, 0.66 V at 1.65 V, 0.92 V at 2.3 V, and 1.31 V at 3.0 V. This proportional behavior ensures consistent noise margin across all supported rails.

Is the X2SON6 (SOT1255-2) package compatible with standard reflow profiles?

Yes - the SOT1255-2 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) and supports standard lead-free reflow profiles (peak 260 °C). Its 0.32 mm profile and thermal pad improve solder joint reliability and thermal transfer in dense layouts.
