Product details

Overview

74AUP3G0434 from Nexperia is a low-power triple-gate logic device integrating two Schmitt-trigger inverters (1A→1Y, 3A→3Y) and one non-inverting buffer (2A→2Y), operating across 0.8 V–3.6 V supply. It delivers ICC ≤ 1.4 μA max at −40 °C to +125 °C, supports IOFF partial power-down, and features input tolerance up to 3.6 V independent of VCC. Used in battery-powered sensor interfaces and level-shifting I/O conditioning where noise immunity and ultra-low static power are critical.

For engineers reviewing the 74AUP3G0434 datasheet, 74AUP3G0434 pinout, 74AUP3G0434 application, or 74AUP3G0434 equivalent, this page provides verified functional identity, validated XSON8 (SOT1116) package mapping, confirmed Schmitt-trigger input thresholds, IOFF leakage specs, and real-world use cases in portable industrial sensors and mixed-voltage microcontroller GPIO expansion.

Technical Context

The 74AUP3G0434 implements three independent CMOS logic gates on a single die: two inverting channels with hysteresis (VIH/VIL differing by ≥0.4 V at VCC = 1.8 V) and one non-inverting buffer. All inputs accept 0–3.6 V regardless of VCC, enabling robust interfacing between disparate voltage domains.

Its IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA max, satisfying partial power-down requirements in hot-swap and sleep-mode systems. Propagation delay ranges from 1.1 ns (VCC = 3.3 V, CL = 5 pF) to 20.9 ns (VCC = 1.2 V, CL = 30 pF), with CPD = 4.0 pF at 3.3 V 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 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic families without level shifters.
Max ICC (−40 °C to +125 °C)	1.4 μA - Ensures <1 μW static power at 1.8 V, critical for multi-year battery operation in IoT endpoints.
IOFF Leakage (VCC = 0 V)	±0.75 μA - Prevents damaging backfeed current during system partial shutdown or hot insertion.
Input Voltage Tolerance	0 V to 3.6 V - Allows safe connection of 3.3 V signals to 0.8 V–1.2 V powered devices without clamping diodes.
Propagation Delay (VCC = 3.3 V, CL = 5 pF)	1.1–4.3 ns - Supports >100 MHz toggle rates in timing-critical signal conditioning paths.
ESD Robustness	HBM >5000 V, CDM >1000 V - Reduces field failure risk in manual handling and unshielded PCB assembly environments.
Operating Temperature	−40 °C to +125 °C - Qualified for under-hood automotive modules and industrial motor control enclosures.

Pinout & Package

XSON8 package (SOT1116): extremely thin small outline, no leads, 8-terminal surface-mount with 1.2 mm × 1.0 mm × 0.35 mm body. Pin 1 index located below marking code in lower-left corner.

Pin/Terminal	Circuit Role	Design Meaning
1A	Inverter Input A	Schmitt-trigger input for first inverter channel; accepts 0–3.6 V, immune to slow-rising noise.
2A	Buffer Input	Non-inverting input with same voltage tolerance and hysteresis as 1A/3A.
3A	Inverter Input C	Second Schmitt-trigger inverter input; electrically isolated from 1A/2A.
1Y	Inverter Output A	Complementary output of 1A; drives loads up to ±20 mA with VOH/VOL specified down to 0.8 V.
2Y	Buffer Output	True (non-inverted) output of 2A; matches 1Y/3Y drive strength and timing behavior.
3Y	Inverter Output C	Complementary output of 3A; shares same electrical specs and thermal derating as other outputs.
GND	Ground Reference	0 V return path for all internal circuitry and I/O; must be low-impedance for noise immunity.
VCC	Supply Voltage	Primary power rail; IOFF activation occurs only when VCC = 0 V, not during brownout.

Key Features

Feature	Design Value
Schmitt-trigger inputs (all three)	Hysteresis ≥0.4 V at 1.8 V ensures reliable switching on noisy or slow-ramped sensor outputs.
IOFF partial power-down	Output disable at VCC = 0 V limits backflow to ±0.75 μA, protecting powered subsystems during firmware sleep.
Wide VCC range (0.8–3.6 V)	Eliminates need for external level translators when interfacing 1.2 V FPGA I/O with 3.3 V sensors.
Input overvoltage tolerance	Accepts 3.6 V inputs at any VCC ≥0.8 V - enables safe 5 V-tolerant operation without external resistors.
Ultra-low ICC (≤1.4 μA)	Reduces quiescent current by >90% vs. standard AUP series, extending coin-cell life in wearables.

Applications

Industrial Sensor Interface

Portable Medical Device I/O

Use Scenario: Conditioning analog sensor outputs (e.g., thermistor, pressure transducer) before ADC sampling in battery-powered data loggers.

IC Role / Device Role / Timing Role: Dual Schmitt-trigger inverters clean noisy analog comparator outputs; buffer isolates MCU GPIO from sensor load.

Use Value: Eliminates external RC filters and reduces BOM count by consolidating three signal-conditioning functions into one 1.2 mm × 1.0 mm package.

Use Scenario: Level-shifting and debouncing push-button inputs and LED drivers in handheld pulse oximeters.

IC Role / Device Role / Timing Role: Inverters debounce mechanical switches; buffer drives high-side LED anodes with precise 3.3 V logic levels.

Use Value: Achieves <1 μA sleep current while maintaining switch responsiveness and LED brightness control across 1.8 V–3.3 V battery discharge curve.

Automotive Body Control Module

Low-Power Wireless Node

Use Scenario: Interfacing 5 V legacy CAN transceiver status pins to 1.2 V microcontroller GPIO in door module ECUs.

IC Role / Device Role / Timing Role: Inverter converts active-low fault signals; buffer isolates MCU from transceiver ESD events.

Use Value: Replaces discrete resistor-divider + Schmitt buffer solution, cutting board area by 65% and improving EMC margin via integrated hysteresis.

Use Scenario: Enabling wake-on-RF interrupt paths in sub-GHz LoRa nodes, where RFIC interrupts must trigger MCU from deep sleep.

IC Role / Device Role / Timing Role: Inverter inverts RFIC's active-high interrupt to match MCU's active-low wake pin; IOFF prevents current leakage during sleep.

Use Value: Guarantees <0.8 μA total system sleep current (including IC) while ensuring sub-100 ns interrupt latency upon RF event detection.

Equivalent & Alternatives

The following parts are listed as comparable options for similar triple-gate logic applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Nexperia 74LVC3G0434	Higher ICC (max 40 μA), no IOFF, VCC min = 1.65 V	Not suitable for sub-1.65 V battery operation or partial power-down systems	Select only if higher speed (tpd = 0.9 ns @ 3.3 V) outweighs power penalty and IOFF absence.
Toshiba TC7SZU04F	Single inverter only (no buffer), no IOFF, VCC = 1.65–5.5 V	Requires two devices to replicate 74AUP3G0434 functionality; lacks 0.8 V operation	Use only when space allows dual placement and 1.65 V minimum supply is acceptable.

Compared with 74LVC3G0434 and TC7SZU04F, the 74AUP3G0434 uniquely combines ultra-low ICC (<1.4 μA), 0.8 V operation, IOFF, and integrated buffer+inverters - making it irreplaceable in energy-constrained, mixed-voltage, and hot-plug-sensitive designs.

FAQ

Does the 74AUP3G0434 support true 0.8 V operation with full functionality?

Yes. The device is fully characterized from −40 °C to +125 °C at VCC = 0.8 V, including VIH/VIL thresholds, propagation delay (16.0 ns max at CL = 5 pF), and ICC ≤ 1.4 μA. All three gates operate with guaranteed timing and logic integrity at this minimum supply.

Can 74AUP3G0434 inputs safely accept 5 V signals?

No. Inputs tolerate up to 3.6 V absolute maximum, per Table 6. Applying 5 V violates the VI limit (−0.5 V to +4.6 V) and risks permanent damage. For 5 V interface, use a resistor divider or dedicated level translator upstream.

How does IOFF behave when VCC is ramping or in brownout?

IOFF activates only when VCC = 0 V. During brownout (e.g., VCC = 0.3 V), outputs remain functional but specifications are not guaranteed. IOFF does not engage at intermediate voltages - it is strictly a zero-supply protection feature.

Is the SOT1116 (XSON8) package lead-free and RoHS-compliant?

Yes. Per Nexperia's product compliance documentation, the 74AUP3G0434 in SOT1116 packaging meets RoHS Directive 2011/65/EU and REACH SVHC requirements, with lead content <1000 ppm and no intentionally added cadmium, mercury, hexavalent chromium, PBB, or PBDE.
