Product details

Overview

74AUP3G14DCH 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 = 0.79–1.31 V at VCC = 3.0 V), operates across 0.8 V to 3.6 V supply, delivers jitter-free output transitions, and supports partial power-down via IOFF circuitry. It is used in waveform shaping and relaxation oscillator circuits in battery-powered IoT sensors and portable medical monitors.

For engineers reviewing the 74AUP3G14DCH datasheet, 74AUP3G14DCH pinout, 74AUP3G14DCH application, or 74AUP3G14DCH equivalent, key selection criteria include input hysteresis voltage (VT+ − VT−), 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), supply current (≤1.4 μA over −40 °C to +125 °C), and VSSOP8 package compatibility with high-density PCB layouts.

Technical Context

The 74AUP3G14DCH implements three independent Schmitt-trigger inverters with asymmetric switching thresholds: VT+ ranges from 0.30 V (VCC = 0.8 V) to 2.32 V (VCC = 3.0 V), while VT− ranges from 0.10 V to 1.24 V. This hysteresis enables robust noise immunity against slow-rising or noisy input signals.

Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V, and it maintains full functionality across −40 °C to +125 °C ambient temperature. Dynamic performance is load- and voltage-dependent: tpd varies from 1.5 ns (3.0 V, 5 pF) to 7.4 ns (3.0 V, 30 pF), with CPD = 4.3 pF enabling precise dynamic power estimation.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	0.8 V to 3.6 V - Enables direct interface with sub-1V logic families and compatibility with Li-ion, coin-cell, and multi-rail embedded systems.
Max ICC (Static)	1.4 μA at −40 °C to +125 °C - Ensures <1 μW static power at 1.8 V, critical for always-on sensor nodes.
Hysteresis Voltage (VH)	0.79–1.31 V at VCC = 3.0 V - Provides ≥400 mV noise margin for reliable edge detection in EMI-prone environments.
Propagation Delay (tpd)	1.5 ns (min) at VCC = 3.0 V, CL = 5 pF - Supports >200 MHz clock clean-up in timing-critical signal paths.
IOFF Leakage	±0.75 μA at VCC = 0 V - Prevents cross-conduction and bus contention in hot-swap or multi-voltage domain systems.
Input Voltage Tolerance	0 V to 3.6 V - Allows interfacing with higher-voltage peripherals without level shifters.
Operating Temperature	−40 °C to +125 °C - Qualified for under-hood automotive, industrial control, and extended-range portable equipment.

Pinout & Package

VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; pin 1 indicator located on lower-left corner below marking code.

Pin/Terminal	Circuit Role	Design Meaning
1A, 2A, 3A	Data input (three independent channels)	Accepts standard CMOS-level signals with Schmitt-trigger hysteresis; tolerant up to 3.6 V regardless of VCC.
1Y, 2Y, 3Y	Data output (inverted, buffered)	Provides sharp-edged, jitter-free transitions; drives capacitive loads up to 30 pF with guaranteed timing.
GND	Ground reference (0 V)	Common return path for all inputs, outputs, and supply; must be low-impedance for noise immunity.
VCC	Positive supply rail	Single supply powers all three inverters; IOFF activates automatically when VCC = 0 V.

Key Features

Feature	Design Value
Ultra-low static power	ICC ≤ 1.4 μA across full temp range - extends battery life in energy-harvesting and wearable devices.
IOFF partial power-down	Blocks backflow current when VCC = 0 V - enables safe insertion/removal in live-backplane systems.
Wide hysteresis window	VH = 0.79–1.31 V at 3.0 V - rejects >300 mV of common-mode noise on sensor or switch inputs.
High noise immunity	VIH/VIL thresholds track VCC proportionally - maintains consistent switching margins across supply variations.
ESD robustness	HBM >5000 V, CDM >1000 V - survives handling and board assembly without external protection.

Applications

Waveform Shaping

Astable Multivibrator

Use Scenario: Converting slow-rising analog sensor outputs (e.g., thermistor RC decay) into clean digital pulses for microcontroller GPIO capture.

IC Role / Device Role: Schmitt-trigger inverter providing hysteresis-based thresholding and edge sharpening.

Use Value: Eliminates contact bounce and EMI-induced false triggers; enables reliable zero-crossing detection without software debouncing.

Use Scenario: Generating continuous square-wave clock signals in low-power timing circuits using two inverters and an RC network.

IC Role / Device Role: One inverter stage provides phase inversion; feedback loop with resistor-capacitor sets oscillation frequency.

Use Value: Delivers stable, supply-voltage-independent frequency (e.g., 10–100 kHz) with no external crystal or timing IC required.

Monostable Multivibrator

Power Sequencing Control

Use Scenario: Generating fixed-duration pulses in response to manual button presses or interrupt events in portable instrumentation.

IC Role / Device Role: Inverter-based pulse stretcher triggered by edge-detected input; RC time constant defines pulse width.

Use Value: Produces jitter-free, repeatable pulse widths (e.g., 100 ms) immune to supply ripple or mechanical switch chatter.

Use Scenario: Enabling controlled power-up sequencing of multiple voltage rails in FPGA or SoC subsystems.

IC Role / Device Role: Inverter with IOFF isolates downstream enable lines during main supply ramp-up or brownout.

Use Value: Prevents latch-up and undefined states by holding peripheral enables inactive until VCC stabilizes above 0.8 V.

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 ≈ 0.5 V at 3.3 V	Requires ≥1.65 V supply; unsuitable for sub-1V systems or partial power-down scenarios	Select when interfacing with 3.3 V/5 V logic and IOFF is not required.
74LVC1G14GV	Single-channel only; same VCC range (1.65–5.5 V); no IOFF; SOT753 package (5-pin)	Lacks channel density and ultra-low-VCC support; occupies more board area per function	Choose for space-constrained single-inverter needs where 0.8 V operation is unnecessary.

Compared with SN74LVC3G14DCUR and 74LVC1G14GV, the 74AUP3G14DCH uniquely supports 0.8 V operation, delivers sub-2 μA static current, and includes IOFF-making it the only option for battery-critical, multi-rail, or hot-plug-capable designs requiring triple Schmitt inversion.

FAQ

What is the minimum supply voltage for guaranteed operation of the 74AUP3G14DCH?

The device is fully specified from 0.8 V to 3.6 V. At VCC = 0.8 V, it guarantees VT+ = 0.30–0.60 V and VT− = 0.10–0.60 V, with tpd ≤19.9 ns (CL = 5 pF) and ICC ≤1.4 μA. Operation below 0.8 V is not characterized or warranted.

Does the 74AUP3G14DCH support mixed-voltage interfacing?

Yes: inputs tolerate up to 3.6 V independent of VCC, enabling connection to higher-voltage peripherals (e.g., 3.3 V sensors) while operating at 1.2 V or 1.8 V. Outputs swing rail-to-rail (0 V to VCC), so level-shifting is required for driving 3.3 V loads from a 1.2 V supply.

How does the IOFF feature behave during power-down?

When VCC = 0 V, the IOFF circuit disables all three outputs (1Y, 2Y, 3Y), presenting high-impedance states that prevent backflow current-even if input or output pins are biased to 3.6 V. IOFF leakage remains ≤±0.75 μA, ensuring safe isolation in multi-supply systems.

Can the 74AUP3G14DCH be used in oscillator circuits?

Yes: its Schmitt-trigger action and low propagation delay make it ideal for astable and monostable multivibrators. Figure 13 in the datasheet shows a validated relaxation oscillator using one inverter, resistor, and capacitor; frequency stability is maintained across VCC and temperature due to proportional VT+/VT− tracking.
