Product details
Overview
74AUP3G34GXX 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 74AUP3G34GXX datasheet, 74AUP3G34GXX pinout, 74AUP3G34GXX application, or 74AUP3G34GXX equivalent, key selection criteria include its sub-1 μA static current, IOFF-enabled isolation during system sleep modes, Schmitt-trigger hysteresis (≥0.3×VCC), and compatibility with mixed-voltage logic domains (inputs tolerate up to 3.6 V independent of VCC).
Technical Context
This device implements three independent non-inverting buffers, each with Schmitt-trigger input thresholds that provide ≥0.3×VCC hysteresis - enabling robust operation with slow-rising or noisy signals. The IOFF circuit actively disables outputs when VCC = 0 V, limiting backflow current to ±0.75 μA maximum.
It complies with JEDEC standards JESD8-12 through JESD8-B across five voltage bands and meets HBM ESD >5000 V and CDM >1000 V. Propagation delay ranges from 1.0 ns (VCC = 3.3 V, CL = 5 pF) to 20.8 ns (VCC = 1.2 V, CL = 30 pF), scaling predictably with load and supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 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 without level shifters. |
| Max ICC (Static) | 0.9 μA at +125 °C - ensures negligible battery drain in always-on sensor nodes or real-time clock backup paths. |
| IOFF Leakage | ±0.75 μA at VCC = 0 V - prevents damaging back-current when one rail powers down while others remain active. |
| Input Hysteresis | ≥0.3×VCC - rejects noise spikes up to 30% of supply, critical for pushbutton debouncing or analog-sensor digitization. |
| Propagation Delay | 1.0 ns to 20.8 ns (CL = 5–30 pF, VCC = 0.8–3.6 V) - supports timing-critical signal routing in high-speed MCU peripheral buses. |
| ESD Rating | HBM >5000 V, CDM >1000 V - sustains handling and board-level transients without external protection components. |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive modules, industrial PLC I/O, and outdoor IoT edge devices. |
Pinout & Package
X2SON8 package (SOT1233-2): plastic thermal-enhanced extremely thin small outline, no leads, 8 terminals, body size 1.35 × 0.8 × 0.32 mm, pin 1 index located on lower-left corner below marking code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Data input (three independent channels) | Accepts DC or slow-edge signals up to 3.6 V regardless of VCC; Schmitt-triggered for noise margin. |
| 1Y, 2Y, 3Y | Data output (three independent channels) | Drives capacitive loads ≤30 pF with rail-to-rail swing; IOFF disables output when VCC = 0 V. |
| GND | Ground reference (0 V) | Common return path for all inputs, outputs, and internal circuitry; must be low-impedance for noise immunity. |
| VCC | Supply voltage input | Power rail for internal logic; IOFF activation is tied directly to this pin's state. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 0.8 V to 3.6 V - eliminates need for separate voltage translators in multi-rail embedded systems. |
| IOFF partial power-down | Active output disable at VCC = 0 V - enables safe hot-plug operation and zero-power standby in modular designs. |
| Schmitt-trigger inputs | Hysteresis ≥0.3×VCC - removes need for external RC debounce networks in mechanical switch or sensor interfaces. |
| Ultra-low ICC | ≤0.9 μA max at +125 °C - extends battery life in coin-cell-powered wearables and remote sensors beyond 10 years. |
| High-noise immunity | Overshoot/undershoot <10% of VCC - maintains signal integrity in electrically noisy environments like motor drives or power supplies. |
Applications
| Portable Sensor Interface | MCU I/O Expansion |

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 (max 10 μA), no IOFF, wider VCC (1.65–5.5 V), no Schmitt inputs | Requires external pull-ups and lacks power-down isolation; suitable only for always-on 3.3 V/5 V systems | Select only if higher drive strength (24 mA) is required and IOFF is unnecessary. |
| 74LVC1G34GW | Single-channel, same VCC range and IOFF, but no Schmitt inputs; smaller XSON6 package | Lacks noise immunity for slow signals; requires three units to match channel count | Choose only for space-constrained single-buffer use cases where input slew rate exceeds 200 ns/V. |
Compared with SN74LVC3G34DCUR and 74LVC1G34GW, the 74AUP3G34GXX uniquely combines triple-channel integration, sub-1 μA static current, Schmitt-trigger noise rejection, and IOFF - making it the sole option for ultra-low-power, noise-prone, multi-rail systems requiring guaranteed power-down safety.

FAQ
Does 74AUP3G34GXX support true bidirectional signal flow?
No - it is a unidirectional non-inverting buffer with dedicated input (A) and output (Y) pins per channel. There is no internal direction-control logic or bus-switch functionality. Each of the three channels operates independently from input to output only, with no feedback path or enable/disable per channel beyond global VCC control.
Can 74AUP3G34GXX be used with 5 V inputs?
No - absolute maximum input voltage is +4.6 V, but recommended operating input voltage is limited to 0–3.6 V per datasheet Table 6. Inputs exceeding 3.6 V risk violating the 0.3×VCC hysteresis specification and may cause excessive ICC or premature wear. For 5 V-tolerant interfacing, an external voltage divider or level translator is required.
What is the thermal performance difference between SOT1233-2 and other packages?
The SOT1233-2 (X2SON8) package has a higher total power dissipation rating (300 mW vs. 250 mW for VSSOP8/XSON8 variants) and improved thermal resistance due to its copper-exposed thermal pad design. This allows sustained operation at +125 °C ambient with higher output loading or longer duty cycles without derating penalties.
Is the IOFF feature activated automatically when VCC drops below a threshold?
Yes - IOFF activates when VCC falls below approximately 0.2 V, disabling all outputs and limiting leakage to ±0.75 μA. This occurs without external control signals or biasing; the circuitry is intrinsic to the silicon design and requires no configuration. Output remains high-impedance until VCC rises above the functional minimum (~0.8 V).
