Product details

Overview

74AUP3G14GM,125 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 inverting buffers with hysteresis (VH = 0.79 V min at VCC = 3.0 V), operates across 0.8 V–3.6 V supply, delivers jitter-free output transitions, and supports partial power-down via IOFF circuitry. It is used in wave shaping and relaxation oscillator circuits in battery-powered IoT sensors and portable medical monitors.

For engineers reviewing the 74AUP3G14GM,125 datasheet, 74AUP3G14GM,125 pinout, 74AUP3G14GM,125 application, or 74AUP3G14GM,125 equivalent, this device is selected when precise input hysteresis, sub-1 μA static ICC, and guaranteed operation down to 0.8 V are required - especially in space-constrained, thermally sensitive, or always-on edge-node designs.

Technical Context

The 74AUP3G14GM,125 implements three independent Schmitt-trigger inverters in a single monolithic CMOS die, each with asymmetric input thresholds (VT+ = 1.88 V, VT− = 0.88 V at VCC = 3.0 V) enabling robust noise rejection on slow-rising signals. Its IOFF feature actively disables outputs during power-down, limiting backflow current to ±0.75 μA max at VCC = 0 V.

It uses advanced AUP (Advanced Ultra Low Power) process technology to achieve 0.9 μA max ICC across −40 °C to +125 °C while maintaining propagation delay as low as 1.5 ns (CL = 5 pF, VCC = 3.0 V). Input voltage tolerance up to 3.6 V allows interfacing with higher-voltage logic without level shifters.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage 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
Max Static Supply Current	1.4 μA at −40 °C to +125 °C - ensures nanoamp-level quiescent draw in always-on sensor nodes
Hysteresis Voltage (VH)	0.79 V min at VCC = 3.0 V - rejects >700 mV of common-mode noise on input edges
Propagation Delay	1.5 ns min (CL = 5 pF, VCC = 3.0 V) - supports >200 MHz clock clean-up in timing-critical paths
IOFF Leakage Current	±0.75 μA max at VCC = 0 V - prevents damaging backfeed in multi-rail partial-power-down systems
Input Voltage Tolerance	0 V to 3.6 V - allows safe connection to 3.3 V drivers even when VCC = 1.8 V
Operating Temperature	−40 °C to +125 °C - qualified for under-hood automotive and industrial control environments

Pinout & Package

XSON8 package (SOT1203): extremely thin small outline, no leads, 1.35 mm × 1.0 mm × 0.35 mm body, 8-terminal surface-mount design optimized for high-density PCB layouts and thermal performance in compact enclosures.

Pin/Terminal	Circuit Role	Design Meaning
1	3A (Input)	Third inverter input; accepts standard CMOS levels up to 3.6 V regardless of VCC
2	3Y (Output)	Third inverter output; driven high/low with VOH ≥ 2.30 V / VOL ≤ 0.50 V at VCC = 3.0 V
3	1Y (Output)	First inverter output; electrically isolated from other outputs; supports independent load switching
4	GND	Digital ground reference; must be low-impedance return path for all three channels
5	2Y (Output)	Second inverter output; shares same VCC/GND but has independent drive capability
6	2A (Input)	Second inverter input; Schmitt-trigger threshold hysteresis applies independently per channel
7	1A (Input)	First inverter input; pin 1 index located below marking code; compatible with automated optical alignment
8	VCC	Single supply rail; powers all three inverters; IOFF activation occurs when VCC = 0 V

Key Features

Feature	Design Value
Triple independent Schmitt triggers	Enables simultaneous wave shaping of three asynchronous analog or noisy digital signals without cross-talk
IOFF partial power-down	Prevents reverse current flow through powered-down sections in mixed-supply systems, eliminating need for external isolation switches
Ultra-low ICC (≤1.4 μA)	Extends battery life in coin-cell-powered devices beyond 10 years in sleep mode (e.g., BLE beacon wake-up circuits)
Input overvoltage tolerance (3.6 V)	Eliminates external clamping diodes when interfacing with legacy 3.3 V peripherals in 1.8 V systems
ESD robustness (HBM 5 kV, CDM 1 kV)	Reduces field failure risk during manual handling and board assembly in uncontrolled environments

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 (10 μA typ); no IOFF; VH = 0.35 V min at VCC = 3.3 V	Better suited for 5 V legacy interfaces; unsuitable for sub-1.2 V operation or zero-VCC isolation	Select when interfacing with 5 V logic and thermal budget allows higher static power
74LVC1G14GW,125	Single-channel only; identical VCC range and IOFF; VH = 0.35 V min at VCC = 3.3 V; same XSON6 package	Requires three separate placements for triple functionality; increases layout area and BOM count	Select when design requires modularity, testability per channel, or incremental channel enablement

Compared with SN74LVC3G14DCUR and 74LVC1G14GW,125, the 74AUP3G14GM,125 uniquely combines triple integration, sub-1 μA ICC, 0.8 V minimum operation, and IOFF - making it the only choice for miniaturized, battery-critical, multi-rail systems requiring guaranteed zero-backfeed behavior.

FAQ

What is the minimum supply voltage at which 74AUP3G14GM,125 guarantees full functionality?

The device is fully specified from 0.8 V to 3.6 V. At VCC = 0.8 V, it maintains functional Schmitt-trigger behavior with VT+ = 0.30 V and VT− = 0.10 V (min), propagation delay ≤19.9 ns (CL = 5 pF), and ICC ≤1.4 μA - confirmed across −40 °C to +125 °C per datasheet Table 7 and Table 10.

Does 74AUP3G14GM,125 support hot insertion or live swapping in multi-rail systems?

Yes - its IOFF circuitry actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA max. This prevents damage during hot-plug events in systems with powered-backplane architectures, such as modular industrial I/O carriers or reconfigurable test equipment.

Can the three inverters be used with different supply voltages simultaneously?

No - the device has a single VCC pin (pin 8) and GND pin (pin 4). All three Schmitt inverters share the same supply rail; independent voltage domains are not supported. For multi-supply signal translation, discrete level-shifters or dual-supply logic families are required.

How does the hysteresis voltage (VH) vary with supply voltage and temperature?

VH = VT+ − VT− ranges from 0.07 V (min, VCC = 0.8 V) to 1.31 V (max, VCC = 3.0 V) at 25 °C, and remains stable across temperature: at −40 °C to +125 °C, VH stays within ±0.02 V of room-temperature values per datasheet Table 11, ensuring consistent noise margin in automotive under-hood environments.
