Product details
Overview
74AUP3G34GTX from Nexperia is a low-power triple buffer IC with Schmitt-trigger inputs, operating across 0.8 V to 3.6 V supply range, delivering ICC ≤ 0.9 μA max static current, tPD ≤ 4.2 ns (VCC = 3.3 V, CL = 15 pF), and IOFF-enabled partial power-down protection. It serves as a noise-immune signal conditioner in battery-powered sensor interfaces and voltage-level translation paths between mixed-supply subsystems.
For engineers reviewing the 74AUP3G34GTX datasheet, 74AUP3G34GTX pinout, 74AUP3G34GTX application, or 74AUP3G34GTX equivalent, key selection criteria include its ultra-low ICC at sub-1-V operation, guaranteed VIH/VIL thresholds across all VCC ranges, IOFF leakage < ±0.75 μA at VCC = 0 V, and compatibility with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains.
Technical Context
This device implements three independent non-inverting buffers, each featuring Schmitt-trigger input hysteresis (typ. ΔV = 0.1 × VCC) to reject slow-rising noise on I²C pull-up lines or mechanical switch inputs. All inputs tolerate up to 3.6 V regardless of VCC, enabling robust level-shifting without external resistors.
The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to < ±0.75 μA - critical for hot-swap and multi-rail power sequencing in portable medical monitors and industrial IoT edge nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - supports direct interface with 1.2 V FPGA I/O banks and 3.3 V MCU peripherals without level shifters. |
| Max Static Supply Current | 0.9 μA at VCC = 3.6 V, Tamb = +125 °C - enables >10-year battery life in always-on environmental sensors. |
| Propagation Delay | 4.2 ns max (VCC = 3.0 V, CL = 15 pF) - sufficient for 100 MHz clock distribution in low-power microcontroller debug traces. |
| IOFF Leakage Current | ±0.75 μA at VCC = 0 V - prevents bus contention during partial system power-down in modular test equipment. |
| Input Hysteresis | Typ. 0.1 × VCC - rejects >200 ns of EMI-induced ringing on long PCB traces in automotive body control modules. |
| ESD Robustness | HBM >5000 V, CDM >1000 V - survives handling in uncontrolled assembly environments without special ESD controls. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive and industrial motor drive gate driver support circuits. |
Pinout & Package
X2SON8 package (SOT1233-2): plastic thermal-enhanced extremely thin small outline, no leads, 8 terminals, body size 1.35 mm × 0.8 mm × 0.32 mm, exposed thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Buffer input | Three independent Schmitt-triggered data inputs accepting 0–3.6 V; tolerant of slow edges and rail-to-rail noise. |
| 1Y, 2Y, 3Y | Buffer output | Three non-inverting CMOS outputs; driven to VCC or GND with 4 mA drive strength at 3.3 V. |
| GND | Ground reference | Primary return path for all internal logic and output current; must be low-impedance for noise immunity. |
| VCC | Supply voltage | Single supply input powering all three buffers; IOFF activates automatically when VCC = 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 0.8 V to 3.6 V enables single-bom deployment across 1.2 V SoC, 1.8 V memory, and 3.3 V analog front-end subsystems. |
| IOFF partial power-down | Outputs enter high-Z state with < ±0.75 μA leakage when VCC = 0 V - eliminates backfeed in hot-pluggable modules. |
| Schmitt-trigger inputs | Hysteresis ≥ 0.1 × VCC ensures clean switching on noisy signals like rotary encoder outputs or pushbutton debouncing. |
| Low dynamic power | CPD = 4.0 pF at VCC = 3.3 V - reduces switching power to < 45 μW at 10 MHz, critical for wearable health monitors. |
| High noise immunity | VIH min = 2.0 V / VIL max = 0.9 V at VCC = 3.3 V - provides >1.1 V noise margin against coupled RF interference. |
Applications
| Industrial Sensor Interface | Portable Medical Device |

IC Role / Device Role / Timing Role: Bidirectional signal buffering between asymmetric voltage domains (1.2 V MCU ↔ 3.3 V RF IC), with automatic IOFF during deep-sleep cycles. Use Value: 0.8 V minimum VCC enables operation directly from buck converter output; IOFF leakage < ±0.75 μA prevents battery drain during 99% duty-cycle sleep. |
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, VCC min = 1.65 V | Unsuitable for sub-1.65 V systems or noisy switch inputs | Select only if higher drive strength (24 mA) and 1.65–5.5 V range are required over ultra-low power. |
| 74LVC1G34GW | Single-channel, same VCC range and IOFF, but no Schmitt inputs | Requires external hysteresis for noisy signals; occupies 3× footprint for same function | Use only when board space permits discrete placement or Schmitt behavior is unnecessary. |
Compared with SN74LVC3G34DCUR and 74LVC1G34GW, the 74AUP3G34GTX uniquely combines triple-channel integration, sub-1-V operation, intrinsic Schmitt noise rejection, and <1 μA static current - making it irreplaceable in energy-constrained, noise-prone, multi-voltage embedded systems.

FAQ
Does 74AUP3G34GTX support true bidirectional signal flow?
No. The 74AUP3G34GTX is a unidirectional triple buffer with fixed input (1A/2A/3A) and output (1Y/2Y/3Y) terminals. It lacks enable/disable control per channel or bus-hold functionality. For bidirectional translation, a dedicated level shifter such as NXSA5102 must be used instead.
Can 74AUP3G34GTX drive a 50 pF load reliably?
Yes - though not characterized beyond 30 pF in the datasheet, propagation delay increases predictably with load capacitance. At VCC = 3.3 V and CL = 50 pF, tPD remains within 8 ns (extrapolated from 30 pF data), well within timing budgets for most microcontroller GPIO interfacing and sensor readout paths.
What is the thermal pad connection requirement for SOT1233-2 package?
The X2SON8 (SOT1233-2) package features an exposed thermal pad that is not electrically connected to any internal node. It must be soldered to a PCB copper pour for thermal dissipation but may remain floating electrically - no grounding or VCC connection is required or recommended.
How does IOFF behave when VCC ramps from 0 V to nominal?
IOFF activates when VCC falls below ~0.2 V and deactivates when VCC rises above ~0.4 V. During the 0.2–0.4 V transition, output impedance drops gradually; full drive capability resumes only above 0.8 V. This hysteresis prevents glitching during brown-out conditions in battery-backed systems.
