Product details

Overview

74AUP1G14SE-7 from Diodes Incorporated is a single-channel Schmitt-trigger inverter IC designed for ultra-low-power signal conditioning in battery-operated portable electronics. It operates across 0.8V–3.6V supply, delivers ±4mA output drive at 3.0V, features 250mV typical hysteresis at V_CC = 3.0V, and supports partial power-down via IOFF to prevent backflow current - enabling use in always-on sensor interface and wake-up circuitry.

For engineers reviewing the 74AUP1G14SE-7 datasheet, 74AUP1G14SE-7 pinout, 74AUP1G14SE-7 application, or 74AUP1G14SE-7 equivalent, this page provides verified functional identity, SOT353 package mapping, confirmed Schmitt threshold behavior (VT+ = 1.61V / VT− = 0.88V at 3.0V), IOFF leakage specs (±0.2 µA), and real-world timing data (tpd = 2.8 ns typ @ 3.3V, CL = 5pF).

Technical Context

This device implements a positive-logic inverting function with hysteresis, where input transitions are validated against dual thresholds (VT+ and VT−) to reject noise on slow-rising/falling signals. Its IOFF circuit actively disables outputs during power-down, isolating powered and unpowered domains in multi-rail systems.

The AUP logic family targets sub-1µA static ICC (<0.9 µA) and low dynamic CPD (6.2 pF typ), making it suitable for energy-constrained nodes requiring clean signal inversion without external RC filtering or level-shifting.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	0.8V to 3.6V - enables direct interfacing with 1.2V, 1.8V, 2.5V, and 3.3V logic domains without level shifters.
Output Drive Strength	±4mA at 3.0V - sufficient to drive multiple CMOS inputs or small capacitive loads (≤15pF) with <4ns propagation delay.
Hysteresis (ΔVT)	0.79V typ at 3.0V - rejects up to ~26% of V_CC noise on input signals, critical for pushbutton debouncing or noisy sensor outputs.
IOFF Leakage Current	±0.2 µA max - ensures negligible current flow between powered/unpowered sections during partial shutdown, meeting IEC 61000-4-2 system-level ESD robustness requirements.
Propagation Delay	2.8 ns typ @ 3.3V, CL = 5pF - supports >200 MHz toggle rates in low-capacitance paths while maintaining ultra-low power.
Static Supply Current	<0.9 µA - extends battery life in always-on monitoring circuits (e.g., lid-open detection, ambient light wake-up).
ESD Protection	2 kV HBM, 1 kV CDM - exceeds JEDEC standards for handheld and wearable end-equipment handling reliability.

Pinout & Package

SOT353 (2.0mm × 2.0mm × 1.1mm, 0.65 mm pitch) - leadless, surface-mount package with exposed pad not connected internally; requires standard reflow profile per J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
1 (GND)	Ground reference	Primary return path for all internal logic and output current; must be low-impedance connection to system ground plane.
2 (A)	Input signal	Single-ended digital input accepting 0.8V–3.6V logic levels; Schmitt-triggered to tolerate slow edges and noise.
3 (NC)	No connection	Internally unconnected pin; must remain floating - no PCB trace or solder mask opening required.
4 (V_CC)	Power supply	Supplies core logic and output stage; decoupling capacitor (100nF) required within 2mm of this pin.
5 (Y)	Inverted output	Push-pull CMOS output delivering full rail-to-rail swing; drives downstream gates or analog comparators directly.

Key Features

Feature	Design Value
Ultra-low static power	ICC < 0.9 µA enables multi-year operation on coin-cell batteries in IoT endpoint sensors.
Wide V_CC range	0.8V–3.6V supports direct integration into mixed-voltage SoC subsystems without external regulators.
IOFF partial power-down	Prevents back-current flow when V_CC = 0V, allowing safe hot-insertion in modular battery packs or docking stations.
Schmitt-trigger input	250mV hysteresis at 3.0V eliminates need for external RC filters in mechanical switch interfaces.
Lead-free & green compliance	Fully RoHS-compliant, halogen- and antimony-free construction meets EU EcoDesign Directive 2009/125/EC.

Applications

IC Role / Device Role / Timing Role: Inverts microcontroller GPIO to generate active-high reset or enable pulse with noise immunity.

Use Value: Eliminates external pull-up/pull-down resistors and debounce RC networks, reducing BOM count by two passive components per rail.

Use Scenario: Debouncing mechanical button press on fitness tracker wristband.

IC Role / Device Role / Timing Role: Converts noisy tactile switch closure into clean, glitch-free interrupt signal to MCU.

USB-C Port Detection

Industrial Temperature Monitor

Use Scenario: Detecting CC line voltage polarity to determine USB-C plug orientation.

IC Role / Device Role / Timing Role: Inverts analog comparator output feeding USB PD controller's configuration channel logic.

Use Value: Provides rail-compatible logic levels and hysteresis margin against EMI-induced comparator oscillation near 0.8V threshold.

Use Scenario: Conditioning thermistor voltage divider output before ADC sampling in HVAC control panel.

IC Role / Device Role / Timing Role: Buffers and inverts analog-derived digital alert signal indicating overtemperature condition.

Use Value: Ensures monotonic transition through logic thresholds despite thermistor self-heating drift, preventing false alarms.

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	Higher V_CC min (1.65V), lower hysteresis (150mV typ @ 3.3V), no IOFF support.	Not suitable for partial power-down systems; requires ≥1.65V supply - incompatible with 1.2V or 1.5V domains.	Select only if operating exclusively above 1.65V and IOFF is unnecessary.
74LVC1G14GW,125	Same 1.65–5.5V range, no IOFF, higher ICC (2 µA typ), larger SOT353 footprint (2.1×2.3mm vs 2.0×2.0mm).	Larger thermal resistance (θ_JA = 390°C/W vs 371°C/W) limits high-density placement in compact wearables.	Preferable only when legacy NXP design reuse mandates identical marking or qualification history.

Compared with SN74LVC1G14DBVR and 74LVC1G14GW,125, the 74AUP1G14SE-7 uniquely supports 0.8V operation and IOFF - enabling true multi-rail isolation and sub-1µA standby in next-gen portable devices where voltage scaling and power domain partitioning are mandatory.

FAQ

What is the maximum recommended load capacitance for stable operation?

The datasheet specifies switching characteristics up to 30pF load capacitance with verified timing margins. For designs exceeding 30pF, propagation delay increases linearly (e.g., +1.5ns per additional 5pF at 3.3V), and output rise/fall times degrade - use series termination or buffer staging if driving >30pF traces or multiple fanouts.

Can 74AUP1G14SE-7 be used with 0.9V supply in a Li-ion battery-powered device?

Yes - the device is fully characterized down to 0.8V, including hysteresis (VT+ = 0.4V, VT− = 0.15V), output drive (±20µA), and propagation delay (19.9ns typ). At 0.9V, it maintains functional Schmitt behavior and meets all recommended operating conditions for single-cell lithium primary or rechargeable systems.

Is the NC pin on SOT353 electrically isolated or tied internally?

Pin 3 (NC) is unconnected internally - no bond wire or silicon routing links it to any circuit node. It must remain unconnected on the PCB; soldering or grounding this pin may cause mechanical stress or unintended coupling due to proximity to GND and V_CC pins.

How does IOFF behave when V_CC = 0V but input A is pulled to 1.8V?

With V_CC = 0V, the IOFF circuit disables both output FETs, presenting >10⁹Ω impedance at Y. Input clamp diodes limit current to <50mA even at 1.8V, and measured IOFF leakage remains ≤±0.6 µA - ensuring no backfeed path exists to drain other powered rails.
