Product details

Overview

74AUP3G34GSX from Nexperia is a low-power triple buffer IC with Schmitt-trigger inputs, designed for signal conditioning and noise-immune level translation in battery-powered and space-constrained systems. It operates across 0.8 V to 3.6 V supply, delivers ≤0.9 μA max ICC, supports partial power-down via IOFF, and functions from −40 °C to +125 °C - used in portable sensor interfaces and ultra-low-power microcontroller I/O expansion.

For engineers reviewing the 74AUP3G34GSX datasheet, 74AUP3G34GSX pinout, 74AUP3G34GSX application, or 74AUP3G34GSX equivalent, key selection criteria include its 0.8 V minimum VCC compatibility, IOFF-enabled isolation during system sleep states, Schmitt-trigger input hysteresis (≥0.3×VCC), sub-1 ns propagation delay at 3.3 V/15 pF load, and XSON8 (SOT1203) 1.35 × 1.0 × 0.35 mm package.

Technical Context

This device implements three independent non-inverting buffers, each featuring Schmitt-trigger inputs to tolerate slow-rising signals and reject high-frequency noise. Its IOFF circuit actively disables outputs when VCC = 0 V, preventing backflow current into powered-down subsystems - critical for mixed-voltage domain sequencing.

All inputs accept up to 3.6 V regardless of VCC, enabling level-shifting between 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains. Dynamic performance is characterized across four temperature ranges (−40 °C to +125 °C), with propagation delay specified down to 1.4 ns (typ.) at VCC = 3.0 V and CL = 5 pF.

Key Specifications

Parameter	Value and Actual Design Meaning
VCC Range	0.8 V to 3.6 V - enables direct interface with modern ultra-low-voltage MCUs and SoCs without level shifters.
ICC (max)	0.9 μA at 25 °C - ensures negligible quiescent drain in always-on sensor nodes and real-time clock domains.
tpd (typ.)	1.4 ns at VCC = 3.0 V, CL = 5 pF - supports high-speed data routing in compact timing-critical paths.
IOFF Leakage	±0.75 μA max at VCC = 0 V - guarantees safe isolation during partial power-down without external blocking diodes.
VIH/VIL Hysteresis	Min. 0.3×VCC - provides ≥240 mV noise margin at 0.8 V supply, rejecting EMI in noisy industrial environments.
ESD Rating	HBM >5000 V, CDM >1000 V - eliminates need for external ESD protection in handheld and wearable designs.
Operating Temp	−40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor control PCBs.

Pinout & Package

XSON8 package (SOT1203): plastic extremely thin small outline, no leads, 8 terminals, body dimensions 1.35 mm × 1.0 mm × 0.35 mm, thermal pad optional, pin 1 marked by laser etch in lower-left corner below marking code "aA".

Pin/Terminal	Circuit Role	Design Meaning
1A, 2A, 3A	Input (3 independent)	Accepts 0–3.6 V logic signals; Schmitt-triggered for noise immunity and monotonic transition.
1Y, 2Y, 3Y	Output (3 independent)	Non-inverting buffered output; drives capacitive loads up to 30 pF with controlled edge rates.
GND	Ground reference	0 V return path for all internal circuitry and output current sinks.
VCC	Supply voltage	Single rail powers all three buffers; IOFF activates automatically when VCC = 0 V.

Key Features

Feature	Design Value
Ultra-low static power	ICC ≤ 0.9 μA max across full VCC and temperature range - extends battery life in coin-cell applications.
IOFF partial power-down	Outputs enter high-Z state with ±0.75 μA leakage when VCC = 0 V - prevents backfeeding in multi-rail systems.
Schmitt-trigger inputs	Hysteresis ≥0.3×VCC - eliminates contact bounce and EMI-induced glitches on mechanical switch or sensor inputs.
Wide voltage interoperability	Inputs tolerate 0–3.6 V regardless of VCC - enables seamless 1.2 V ↔ 3.3 V bidirectional level translation.
JEDEC-compliant packaging	SOT1203 (XSON8) footprint - supports automated placement and reflow in high-density HDI PCBs.

Applications

Portable Medical Sensors

Automotive Body Control Modules

Use Scenario: Signal conditioning for analog sensor outputs (e.g., thermistors, accelerometers) interfacing with ultra-low-power MCU ADC inputs.

IC Role / Device Role / Timing Role: Buffering and noise filtering of slow-rising sensor signals before digitization; Schmitt trigger rejects EMI from nearby motors or RF sources.

Use Value: Eliminates external RC filters and discrete Schmitt triggers, reducing BOM count and board area in disposable wearable patches.

Use Scenario: Isolating wake-up signals from door latch switches and seat occupancy sensors in 12 V vehicle architectures with 3.3 V domain MCUs.

IC Role / Device Role / Timing Role: Level-shifting and debouncing mechanical switch inputs while maintaining IOFF isolation during MCU sleep cycles.

Use Value: Enables reliable wake-on-event functionality with <1 μA standby current draw per channel, meeting ISO 16750-2 quiescent current requirements.

Industrial IoT Edge Nodes

Consumer Wearable Displays

Use Scenario: Driving LED status indicators and SPI bus segments in battery-operated gateways deployed in remote locations.

IC Role / Device Role / Timing Role: Fan-out buffer for GPIO-controlled LEDs and isolated SPI clock/data lines; IOFF prevents reverse current during partial system shutdown.

Use Value: Reduces total system standby power by 300 nA per buffered line versus standard logic, extending field deployment intervals.

Use Scenario: Interfacing capacitive touch controller I/O with OLED display driver in smartwatch mainboard.

IC Role / Device Role / Timing Role: Signal integrity enhancement for high-impedance touch sense lines; Schmitt action suppresses crosstalk from adjacent display data traces.

Use Value: Improves touch response reliability without increasing layout spacing, enabling <0.5 mm trace pitch in constrained 6-layer flex-rigid stacks.

Equivalent & Alternatives

The following parts are listed as comparable options for similar triple buffer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC3G34DCUR	Higher ICC (10 μA typ.), no Schmitt inputs, 1.65–5.5 V VCC range	Lacks noise immunity for slow-switching sensors; requires external hysteresis for switch debouncing	Select only if higher VCC (>3.6 V) or legacy LVC logic family compatibility is required
74LVC1G34GW	Single-channel, same Schmitt + IOFF features, identical SOT353 package	Requires three devices for triple buffering; increases PCB area and assembly cost	Choose when design flexibility demands independent enable control per channel

Compared with SN74LVC3G34DCUR and 74LVC1G34GW, the 74AUP3G34GSX uniquely combines triple buffering, sub-μA quiescent current, Schmitt inputs, and IOFF in a single 1.35 mm × 1.0 mm XSON8 package - delivering optimal integration for space- and power-constrained edge nodes.

FAQ

Does 74AUP3G34GSX support true bidirectional level shifting?

No - it is a unidirectional non-inverting buffer. Inputs accept 0–3.6 V regardless of VCC, enabling upward level translation (e.g., 1.2 V input → 3.3 V output), but outputs cannot drive higher voltages than VCC. For bidirectional translation, dedicated bus switches like NXSA1047 must be used.

Can the IOFF feature be disabled or bypassed?

No - IOFF is an intrinsic, always-active circuit that engages automatically when VCC drops below ~0.2 V. There is no enable/disable pin or configuration register. This ensures fail-safe isolation without firmware intervention during brown-out or controlled power sequencing.

What is the maximum capacitive load this device can drive reliably?

The datasheet specifies dynamic characteristics up to 30 pF load capacitance. At 3.3 V and 25 °C, tpd remains ≤5.1 ns with 30 pF. Driving >30 pF may increase propagation delay nonlinearly and cause overshoot; for >50 pF loads, series termination or a higher-drive buffer is recommended.

Is the SOT1203 (XSON8) package compatible with standard reflow profiles?

Yes - SOT1203 meets JEDEC J-STD-020D moisture sensitivity level 1 (MSL1) and is qualified for standard lead-free reflow profiles (peak 260 °C, 60 s above 217 °C). Its 0.35 mm height and exposed thermal pad (optional) support consistent solder joint formation in automated assembly.
