Product details

Overview

74AUP1G14FS3-7 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 circuitry-enabling robust noise immunity in GPS receivers and e-reader display interfaces.

For engineers reviewing the 74AUP1G14FS3-7 datasheet, 74AUP1G14FS3-7 pinout, 74AUP1G14FS3-7 application, or 74AUP1G14FS3-7 equivalent, key selection criteria include supply voltage flexibility (0.8V–3.6V), Schmitt-trigger hysteresis tolerance for slow-rising sensor signals, IOFF-enabled system-level power sequencing, and DFN0808-4 footprint compatibility with space-constrained PCB layouts.

Technical Context

This device implements a positive-logic inverting function (Y = A̅) with hysteresis-based input thresholding-VT+ = 1.61V and VT− = 0.88V at 3.0V V_CC, yielding ∆VT = 0.73V-ensuring reliable switching despite noisy or slow-transition inputs. Its IOFF circuit actively disables outputs during power-down, blocking reverse current flow between powered and unpowered rails.

Designed for sub-1µA static current (I_CC < 0.9µA) and low dynamic power (C_PD = 6.2pF), it targets high-efficiency signal inversion in always-on sensor nodes and wake-up logic paths where quiescent power dominates total energy budget.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	0.8V to 3.6V - Enables direct interface with Li-ion, coin-cell, and multi-rail SoC I/O domains without level-shifting.
Output Drive Strength	±4mA at 3.0V - Sufficient to drive multiple CMOS loads or small capacitive traces in handheld UI subsystems.
Input Hysteresis (∆VT)	0.79V typical at 3.0V - Rejects up to ~800mV of input noise without false triggering on slow analog-like signals.
Static Supply Current (I_CC)	< 0.9µA - Minimizes battery drain in always-on monitoring circuits over multi-year deployments.
IOFF Leakage Current	±0.2µA max - Prevents backfeed-induced latch-up or data corruption when adjacent rails are powered down.
Propagation Delay (t_PD)	2.8ns typical at 3.3V, CL=5pF - Supports clean digital edge regeneration up to ~100MHz signal rates in timing-critical paths.
ESD Protection	2kV HBM, 1kV CDM - Meets industrial handling requirements without external protection components.

Pinout & Package

The 74AUP1G14FS3-7 uses the X2-DFN0808-4 leadless package: 0.8mm × 0.8mm × 0.35mm body, diamond pad layout, 0.5mm pad pitch, and no exposed thermal pad. Pin 1 is marked by a chamfered corner.

Pin/Terminal	Circuit Role	Design Meaning
1 (NC)	No Connection	Internally unconnected; must be left floating or tied to GND per layout best practice-no electrical function.
2 (GND)	Ground Reference	Primary return path for all internal logic and output current; requires low-inductance connection to system ground plane.
3 (A)	Inverting Input	Accepts TTL/CMOS-compatible signals; Schmitt-trigger thresholds reject noise on slow-rising sensor or switch inputs.
4 (V_CC)	Power Supply	Supplies core logic and output stage; decoupling capacitor (100nF) required within 2mm for stable operation.
5 (Y)	Inverting Output	Push-pull CMOS output driving downstream logic; supports rail-to-rail swing and bidirectional current sourcing/sinking.
6 (NC)	No Connection	Internally unconnected; must be left floating or tied to GND-no routing or soldering required.

Key Features

Feature	Design Value
Ultra-low static power	I_CC < 0.9µA enables multi-year operation on coin-cell batteries in IoT endpoint sensors.
Schmitt-trigger input hysteresis	250mV typical at 3.0V ensures reliable switching on mechanical switch bounce or RC-filtered analog signals.
IOFF partial power-down	Blocks >99.9% of backflow current when V_CC = 0V, enabling safe hot-swap and multi-rail sequencing.
Wide V_CC range (0.8V–3.6V)	Eliminates level shifters in mixed-voltage systems-direct interface with 1.2V, 1.8V, 2.5V, and 3.3V domains.
Lead-free, halogen-free DFN0808-4	0.8mm × 0.8mm footprint reduces board area by 75% vs. SOT353 while maintaining thermal reliability.

Applications

GPS Receiver Signal Conditioning

E-Reader Display Interface

Use Scenario: Cleaning noisy NMEA serial clock edges from GNSS modules before feeding into baseband processor UART inputs.

IC Role / Device Role / Timing Role: Schmitt-trigger inverter regenerates degraded clock waveforms, restoring sharp edges and eliminating metastability in asynchronous domain crossings.

Use Value: Enables reliable 4800–115200 baud communication without external filtering or re-timing PLLs, reducing BOM count by one active component.

Use Scenario: Debouncing tactile buttons controlling page-turn functions in e-ink displays with microsecond-level response requirements.

IC Role / Device Role / Timing Role: Inverter with hysteresis converts slow-rising mechanical switch transitions into clean, jitter-free digital pulses for MCU GPIO interrupts.

Use Value: Eliminates need for software debouncing routines or RC + comparator circuits-reducing firmware complexity and interrupt latency by >10×.

Wearable Sensor Wake-Up Logic

USB-C Port Status Indicator

Use Scenario: Converting analog output from ultra-low-power motion sensor (e.g., accelerometer interrupt) into a clean enable signal for main MCU power domain.

IC Role / Device Role / Timing Role: Low-I_CC inverter acts as power-gating trigger, activated only when sensor asserts valid wake event above hysteresis threshold.

Use Value: Extends wearable battery life by ensuring MCU remains fully off until genuine motion event occurs-cutting average system current by 2.3µA.

Use Scenario: Driving bi-color LED status indicators on USB-C receptacles that must operate across host-supplied 3.3V, 5V, or PD negotiation voltages.

IC Role / Device Role / Timing Role: Level-flexible inverter buffers CC line state changes, providing consistent LED drive regardless of V_CC source (3.3V or 5V).

Use Value: Removes need for dual-voltage LED drivers or discrete FET switches-simplifying layout and enabling single-BOM design for multiple host platforms.

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 V_CC range (1.65V–5.5V); higher I_OH/I_OL (±32mA); no IOFF; larger SOT-23-5 package.	Better suited for 5V industrial control I/O but incompatible with sub-1.65V battery rails and lacks partial power-down capability.	Select when interfacing with legacy 5V logic or requiring higher drive; avoid for coin-cell or multi-rail hot-swap systems.
74LVC1G14GW,125	Same 1.65V–5.5V range; SC-70-5 package (2.0mm × 1.25mm); no IOFF; slightly higher I_CC (1.5µA).	Offers better thermal performance than DFN0808-4 but occupies >3× more PCB area and cannot support 0.8V operation.	Choose for prototyping or lower-volume designs where board space is less constrained and 5V compatibility is mandatory.

Compared with SN74LVC1G14DBVR and 74LVC1G14GW,125, the 74AUP1G14FS3-7 uniquely supports sub-1V operation and IOFF-making it the only viable option for ultra-low-voltage wearables and multi-rail power-gated systems, despite lower drive strength.

FAQ

What is the minimum supply voltage for guaranteed operation?

The 74AUP1G14FS3-7 is fully specified from 0.8V to 3.6V. At 0.8V, it maintains functional logic levels and propagation delay (t_PD ≤ 19.9ns, CL = 5pF), with input thresholds scaled proportionally (VT+ = 0.4V, VT− = 0.15V). Below 0.8V, timing and noise margin degrade unpredictably.

Can Pin 1 (NC) and Pin 6 (NC) be connected to GND?

Yes-Pins 1 and 6 are internally unconnected and may be tied to GND for mechanical stability or ESD mitigation. Diodes Incorporated's recommended pad layout (AP02001) shows both NC pins grounded in standard footprints; doing so improves solder joint reliability without affecting electrical performance.

How does IOFF behave when V_CC = 0V and input A is pulled to 3.3V?

When V_CC = 0V, the IOFF circuit disables the output Y, limiting leakage current to ±0.2µA maximum-even if A is externally biased to 3.3V. This prevents backfeed into the unpowered V_CC rail, protecting downstream regulators and avoiding unintended power-up of adjacent circuits.

Is the X2-DFN0808-4 package compatible with standard reflow profiles?

Yes-the X2-DFN0808-4 meets JEDEC J-STD-020D moisture sensitivity level 1 (MSL-1) and supports standard Pb-free reflow profiles (peak 260°C, 30s dwell). Its 0.35mm height and copper-leadframe construction ensure uniform thermal transfer; recommended stencil aperture is 0.25mm × 0.25mm with 50% area reduction for controlled solder volume.
