Product details
Overview
74AUP1G14FX4-7 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 0.79–1.31V hysteresis (at 3.0V), and supports partial power-down via IOFF circuitry-enabling safe I/O isolation during system sleep modes in wearables and IoT sensors.
For engineers reviewing the 74AUP1G14FX4-7 datasheet, 74AUP1G14FX4-7 pinout, 74AUP1G14FX4-7 application, or 74AUP1G14FX4-7 equivalent, key selection criteria include its sub-1µA static current (ICC < 0.9µA), 2.8ns typical propagation delay at 3.3V/CL=5pF, Schmitt-trigger noise immunity (250mV typical hysteresis), and compatibility with 0.5mm-pitch X2-DFN1409-6 chip-scale packaging for space-constrained PCB layouts.
Technical Context
This device implements a positive-Boolean inverting function (Y = A̅) with hysteresis on the input to reject slow-rising/falling or noisy signals. Its Schmitt-trigger thresholds are voltage-dependent: VT+ = 1.61–2.32V and VT− = 0.88–1.24V at VCC = 3.0V, yielding ∆VT = 0.79–1.31V.
The IOFF feature actively disables output drivers when VCC = 0V, limiting back-current to ±0.2µA (typical) and preventing bus contention in multi-rail systems. Input capacitance is 1.5pF, and dynamic power dissipation is characterized by CPD = 6.2pF (typical at 3.6V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8V to 3.6V - Enables direct interface 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 standard CMOS loads or short PCB traces without buffering. |
| Static Supply Current | ICC < 0.9µA - Minimizes quiescent drain in always-on sensor nodes or real-time clock circuits. |
| Input Hysteresis (∆VT) | 0.79–1.31V at 3.0V - Rejects up to ~400mV of input noise without false triggering on slow edges. |
| Propagation Delay | 2.8ns (typ) at 3.3V/CL=5pF - Supports >100MHz signal edge rates in timing-critical debounce or clock clean-up paths. |
| IOFF Leakage | ±0.2µA (max) - Ensures negligible current flow during power sequencing or hot-swap events. |
| ESD Robustness | 2kV HBM, 1kV CDM - Meets industrial-grade handling requirements without external protection. |
Pinout & Package
X2-DFN1409-6 is a 1.4mm × 0.9mm × 0.4mm chip-scale package with 0.5mm pad pitch and six terminals. Pin 1 is marked by a circular fiducial (Ø0.20–0.30mm) located near the top-left corner in top-view orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No Connection | Unbonded pad - must be left floating or tied to GND per layout guidelines; no electrical function. |
| 2 (GND) | Ground Reference | Primary return path for all internal logic and output currents; requires low-inductance connection to PCB ground plane. |
| 3 (VCC) | Power Supply Input | Accepts 0.8–3.6V; decoupling capacitor (≥100nF) required within 2mm for stable operation. |
| 4 (Y) | Inverted Output | Push-pull CMOS output capable of sourcing/sinking ±4mA; compatible with 3.3V/1.8V logic families. |
| 5 (NC) | No Connection | Unbonded pad - electrically isolated; may be used as thermal relief or left unconnected. |
| 6 (A) | Inverting Input | Schmitt-trigger input with hysteresis; accepts DC or slow AC signals up to 100MHz edge rate. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC < 0.9µA enables >10-year battery life in coin-cell-powered remote controls and environmental sensors. |
| Wide VCC range | 0.8V–3.6V operation supports direct integration into energy-harvesting systems with variable output voltages. |
| IOFF partial power-down | Prevents back-current flow when VCC = 0V, eliminating need for external isolation switches in multi-voltage domain designs. |
| Schmitt-trigger input | 250mV typical hysteresis at 3.0V ensures reliable switching on mechanical switch bounce or RF-coupled noise. |
| Chip-scale footprint | X2-DFN1409-6 (1.4mm × 0.9mm) reduces board area by >60% vs. SOT353, critical for TWS earbuds and smart patches. |
Applications
| Switch Debounce Circuit | Low-Power Sensor Interface |
|---|---|
Use Scenario: Mechanical push-button connected to microcontroller GPIO with long PCB traces in handheld medical device. IC Role / Device Role / Timing Role: Schmitt-trigger inverter provides noise-immune signal conditioning and eliminates contact bounce before MCU sampling. Use Value: Eliminates need for software debouncing or RC filters, reducing firmware complexity and enabling immediate wake-on-press response. | Use Scenario: Analog ambient light sensor output routed through noisy digital section of wearable fitness tracker PCB. IC Role / Device Role / Timing Role: Inverter cleans up slow-rising photodiode amplifier output and converts it to robust digital logic level for ADC trigger. Use Value: Prevents false interrupts caused by EMI coupling; hysteresis ensures stable threshold crossing despite 50mV of induced noise. |
| Battery Voltage Monitor | USB-C Power Path Control |
Use Scenario: Resistive divider from Li-ion cell feeds into comparator reference; output drives enable line of PMIC. IC Role / Device Role / Timing Role: Inverter buffers and inverts comparator output to generate active-low enable signal with rail-to-rail swing. Use Value: Delivers full 3.3V logic swing at <1µA quiescent current-extending runtime in always-monitoring battery gauges. | Use Scenario: USB-C port controller asserts open-drain alert signal; 74AUP1G14FX4-7 converts to push-pull level for host processor interrupt pin. IC Role / Device Role / Timing Role: Signal translator isolates controller's 1.2V I/O from host's 3.3V interrupt line while maintaining fast edge integrity. Use Value: IOFF prevents leakage when host is powered down but port controller remains active-avoiding phantom power draw. |
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 (1.65–5.5V); higher ICC (10µA typ); no IOFF; SOT-23-5 package (2.9mm × 1.6mm). | Requires external pull-up for 1.8V systems; unsuitable for partial power-down architectures. | Select when interfacing legacy 5V peripherals or where board space allows larger package. |
| NC7SZ14P5X | Lower max VCC (4.3V); identical 0.8–3.6V range; ICC = 0.9µA; IOFF supported; SC-70-5 (2.0mm × 1.25mm). | Same functional behavior but 30% larger footprint than X2-DFN1409-6; no NC pins. | Choose if existing SC-70 land pattern is fixed and X2-DFN rework is not feasible. |
Compared with SN74LVC1G14DBVR and NC7SZ14P5X, the 74AUP1G14FX4-7 uniquely combines chip-scale size, sub-1µA ICC, and guaranteed IOFF-making it optimal for miniaturized, battery-sensitive designs where power sequencing integrity is mandatory.

FAQ
What is the maximum operating temperature for 74AUP1G14FX4-7?
The device is rated for continuous operation from −40°C to +125°C ambient temperature. Junction temperature must not exceed +150°C; thermal resistance θJA = 470°C/W for X2-DFN1409-6 means 10mW power dissipation raises junction temp by 4.7°C above ambient-well within limits for typical use cases.
Can 74AUP1G14FX4-7 drive a 50pF load reliably?
Yes, but with increased propagation delay: at 3.3V and CL = 30pF, tPD rises to 6.1ns (max). For 50pF, extrapolation suggests ~7.5ns max delay. Ensure output drive remains within ±4mA limit and verify signal integrity with scope validation-no derating needed for static loading.
Is pin 1 polarity marked on the X2-DFN1409-6 package?
Yes-pin 1 is identified by a circular fiducial (Ø0.20–0.30mm) located at the top-left corner of the package in top-view orientation. This mark aligns with Diodes' AP02002 recommended pad layout and is visible under 20× magnification during automated optical inspection.
Does the NC pin require PCB connection?
No-pins 1 and 5 are unconnected die pads with no internal bond wire. They may be left floating, tied to GND for thermal relief, or omitted from solder paste stencil. Diodes recommends leaving them unconnected unless thermal simulation shows benefit from GND tie.
