Product details

Overview

74AUP3G14GTX from Nexperia is a low-power triple Schmitt trigger inverter IC designed for signal conditioning in ultra-low-voltage digital systems. It provides three independent hysteresis-equipped inverters, operates from 0.8 V to 3.6 V, delivers <0.9 μA max ICC at 25 °C, supports IOFF partial power-down, and functions across –40 °C to +125 °C - enabling robust noise immunity in battery-powered sensor interfaces and timing circuits.

For engineers reviewing the 74AUP3G14GTX datasheet, 74AUP3G14GTX pinout, 74AUP3G14GTX application, or 74AUP3G14GTX equivalent, key selection criteria include input hysteresis voltage (VH ≥ 0.07 V at 0.8 V), propagation delay (as low as 1.5 ns at VCC = 3.0 V, CL = 5 pF), IOFF leakage (<±0.75 μA at VCC = 0 V), and compatibility with 1.2 × 1.0 × 0.35 mm XSON8 (SOT1116) packaging.

Technical Context

The 74AUP3G14GTX implements three independent Schmitt-trigger inverters with asymmetric input thresholds (VT+ and VT−), delivering hysteresis-based waveform sharpening for slow-rising/falling signals. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

It features rail-to-rail input tolerance (VI up to 3.6 V independent of VCC), sub-1.0 μA static supply current, and dynamic performance characterized by CPD = 3.1 pF at 1.65 V - enabling energy-efficient operation in always-on microcontroller peripherals and IoT edge nodes.

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)	1.4 μA at –40 °C to +125 °C - ensures nanoamp-level quiescent power for multi-year battery life in wearables
VH (Hysteresis)	0.79 V min at VCC = 3.0 V - provides strong noise margin against EMI-induced glitches on long PCB traces
tpd (min)	1.5 ns at VCC = 3.0 V, CL = 5 pF - supports >300 MHz clock shaping in high-speed control loops
IOFF Leakage	±0.75 μA max at VCC = 0 V - prevents cross-conduction and bus contention in hot-swap or multi-rail systems
ESD Rating	HBM >5000 V, CDM >1000 V - meets industrial IEC 61000-4-2 immunity requirements without external protection
Operating Temp	–40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and outdoor wireless modules

Pinout & Package

XSON8 package (SOT1116): plastic extremely thin small outline, no leads, 8-terminal, 1.2 × 1.0 × 0.35 mm body. Pin 1 index located on lower-left corner below marking code "pK".

Pin/Terminal	Circuit Role	Design Meaning
1	3A	Third inverter input - accepts standard CMOS/TTL logic levels up to 3.6 V regardless of VCC
2	3Y	Third inverter output - drives capacitive loads ≤30 pF with <4.7 ns delay at 3.0 V
3	1Y	First inverter output - Schmitt-triggered inversion with hysteresis prevents metastability on noisy inputs
4	GND	Digital ground reference - must be connected directly to low-impedance ground plane to maintain noise immunity
5	2Y	Second inverter output - independently buffered; no internal coupling between channels
6	2A	Second inverter input - electrically isolated from other inputs; supports mixed-voltage domain interfacing
7	1Y	First inverter output - matches pin 3 per functional diagram; dual-output labeling reflects package orientation
8	VCC	Supply voltage - powers all three inverters; IOFF activates automatically when VCC = 0 V

Key Features

Feature	Design Value
Triple Schmitt-trigger inversion	Three independent hysteresis buffers in one die - eliminates need for discrete RC networks in oscillator or debouncing circuits
IOFF partial power-down	Output disable at VCC = 0 V with <±0.75 μA leakage - enables safe insertion/removal in live-backplane systems
Ultra-low ICC	1.4 μA max over full temperature range - reduces system standby power by >90% vs. standard AUP-series logic
Rail-tolerant inputs	VI up to 3.6 V at any VCC (0.8–3.6 V) - allows direct connection to higher-voltage sensors or legacy peripherals
High noise immunity	VH ≥ 0.79 V at 3.0 V supply - rejects >26% amplitude noise without additional filtering components

Applications

Waveform Shaping

Astable Multivibrator

Use Scenario: Converting slow-rising analog sensor outputs (e.g., thermistor voltage ramps) into clean digital edges for MCU GPIO capture.

IC Role / Device Role / Timing Role: Schmitt-trigger inverter providing hysteresis-based threshold discrimination and jitter-free edge generation.

Use Value: Eliminates external RC components and software debouncing; achieves sub-5 ns edge jitter at 3.0 V supply.

Use Scenario: Generating precise square-wave clocks for LED drivers or PWM modulators using only two inverters and an RC network.

IC Role / Device Role / Timing Role: One inverter stage configured as relaxation oscillator core; remaining inverters buffer and invert output.

Use Value: Enables stable oscillation from 10 kHz to 2 MHz with <±2% frequency drift over temperature - no external crystal required.

Monostable Multivibrator

Power Sequencing Control

Use Scenario: Creating fixed-duration pulses from push-button presses or interrupt signals in portable medical devices.

IC Role / Device Role / Timing Role: Inverter-based pulse stretcher with RC time constant defining output pulse width.

Use Value: Delivers consistent 10–100 ms pulses across 0.8–3.6 V supply range - immune to supply droop during battery discharge.

Use Scenario: Enabling controlled power-up sequencing of multiple voltage rails (e.g., 1.2 V core before 3.3 V I/O) in FPGA-based systems.

IC Role / Device Role / Timing Role: Inverter used as delay element and level shifter between reset controllers and enable pins of DC/DC converters.

Use Value: Provides >100 ns propagation delay margin and IOFF isolation during brown-out - prevents latch-up during rail transitions.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC3G14DCUR	Wider VCC range (1.65–5.5 V); higher ICC (max 10 μA); no IOFF; VH ≈ 0.3 V at 3.3 V	Suitable for 3.3 V/5 V mixed-signal systems but not sub-1.2 V operation or hot-swap isolation	Select when interfacing with 5 V peripherals and higher drive strength (>24 mA) is needed
74LVC1G14GW,125	Single-channel only; same VCC (1.65–5.5 V); no IOFF; VH ≈ 0.25 V at 3.3 V; SOT353 (5-pin)	Requires three units for triple functionality; lacks power-down capability and ultra-low ICC	Choose for space-constrained single-inverter needs where cost-per-channel is prioritized over integration

Compared with SN74LVC3G14DCUR and 74LVC1G14GW,125, the 74AUP3G14GTX uniquely combines triple integration, sub-1 μA ICC, IOFF, and 0.8 V operation - making it the only option for energy-critical, multi-rail, or hot-pluggable designs requiring Schmitt-trigger signal conditioning.

FAQ

What is the minimum supply voltage for guaranteed operation of the 74AUP3G14GTX?

The 74AUP3G14GTX is fully specified from 0.8 V to 3.6 V. At VCC = 0.8 V, it guarantees VOH ≥ VCC − 0.11 V and VOL ≤ 0.11 V with 20 μA load, and maintains functional hysteresis (VH ≥ 0.07 V). This enables direct use with single-cell LiFePO₄ or NiMH batteries without regulation.

How does the IOFF feature behave during partial power-down?

When VCC = 0 V, the IOFF circuit disables all three outputs (1Y, 2Y, 3Y), limiting leakage to ±0.75 μA maximum regardless of input/output voltage (0–3.6 V). This prevents backflow current into powered sections of the system, satisfying IEC 62379-3 hot-swap safety requirements.

Can the 74AUP3G14GTX drive a 30 pF load at 3.0 V with sub-5 ns propagation delay?

Yes. At VCC = 3.0 V and CL = 30 pF, the typical tpd is 3.8 ns with a maximum of 5.4 ns over –40 °C to +125 °C - verified per Table 8. This meets timing budgets for 100+ MHz clock distribution and high-speed serial interface conditioning.

Is the XSON8 (SOT1116) package of the 74AUP3G14GTX compatible with standard reflow profiles?

Yes. The SOT1116 package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL-1), supporting peak reflow temperatures up to 260 °C. Its 0.35 mm profile and copper-leadframe construction ensure reliable solder joint formation using standard lead-free profiles.
