Product details
Overview
74AUP3G34GT115 from Nexperia is a low-power triple buffer IC with Schmitt-trigger inputs, operating across 0.8 V to 3.6 V supply, delivering ultra-low ICC ≤ 0.9 μA (max), propagation delay as low as 1.4 ns (VCC = 3.3 V, CL = 5 pF), and IOFF-enabled partial power-down protection for system-level power sequencing in portable and battery-powered logic interfaces.
For engineers reviewing the 74AUP3G34GT115 datasheet, 74AUP3G34GT115 pinout, 74AUP3G34GT115 application, or 74AUP3G34GT115 equivalent, this device is selected for high-noise-immunity signal buffering in space-constrained, multi-voltage digital subsystems requiring guaranteed input hysteresis, sub-1 μA static current, and thermal-enhanced XSON8 packaging.
Technical Context
The 74AUP3G34GT115 implements three independent non-inverting buffers with Schmitt-trigger inputs-each providing hysteresis to tolerate slow-rising/falling signals without oscillation. Its IOFF circuitry actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down sequences.
Designed for wide-VCC operation (0.8–3.6 V), it maintains consistent VIH/VIL thresholds across voltage ranges and supports dynamic loading up to 30 pF while sustaining propagation delays under 5.5 ns at 3.3 V-enabling reliable interfacing between mixed-supply domains like 1.2 V, 1.8 V, and 3.3 V logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - Enables direct interface across 1.2 V, 1.8 V, and 3.3 V logic domains without level shifters. |
| Max Static Supply Current | 0.9 μA at VCC = 0.8–3.6 V - Ensures negligible battery drain in always-on sensor nodes or sleep-mode peripherals. |
| Propagation Delay | 1.4 ns (typ) at VCC = 3.0 V, CL = 5 pF - Supports >300 MHz signal integrity for high-speed control path buffering. |
| Input Hysteresis | Schmitt-trigger action - Eliminates contact bounce or noise-induced glitches on mechanical switch or analog sensor inputs. |
| IOFF Leakage | ±0.75 μA max at VCC = 0 V - Prevents damaging back-current during hot-swap or staggered power-up of interconnected boards. |
| ESD Robustness | HBM >5000 V, CDM >1000 V - Survives handling and board assembly without external protection components. |
| Operating Temperature | -40 °C to +125 °C - Qualified for industrial and extended-temperature embedded control applications. |
Pinout & Package
XSON8 package (SOT833-1): plastic extremely thin small outline, no leads, 8-terminal, body size 1.0 mm × 1.95 mm × 0.5 mm, thermal pad optional, pin 1 indicator below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 3A | Third buffer input - Accepts 0–3.6 V signals regardless of VCC; Schmitt-triggered for noise margin. |
| 2 | 1Y | First buffer output - Drives loads up to ±4 mA at 3.3 V; VOL ≤ 0.45 V ensures clean LOW recognition. |
| 3 | VCC | Supply rail - Powers all three buffers; IOFF activates automatically when VCC drops below 0.2 V. |
| 4 | 2Y | Second buffer output - Matches 1Y/3Y timing and drive strength; enables synchronous fan-out distribution. |
| 5 | 2A | Second buffer input - Electrically identical to 1A/3A; allows independent routing of three signal paths. |
| 6 | 3Y | Third buffer output - Fully buffered output with same propagation delay and noise immunity as other channels. |
| 7 | 1A | First buffer input - Primary signal entry point; compatible with open-drain, push-pull, or analog-sourced inputs. |
| 8 | GND | Ground reference - Shared return for all I/O and supply; requires low-impedance connection to minimize ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| Triple independent buffer channels | Enables simultaneous conditioning of three critical control lines (e.g., reset, enable, interrupt) without cross-talk or shared timing skew. |
| Schmitt-trigger inputs | Provides ≥100 mV hysteresis at 1.8 V, rejecting EMI and contact bounce in industrial switch interfaces. |
| IOFF partial power-down | Guarantees output high-impedance state during VCC ramp-down, preventing backfeed into powered subsystems. |
| Ultra-low dynamic power | CPD = 4.0 pF at 3.3 V - Limits switching power to <15 μW per buffer at 1 MHz, ideal for energy-harvesting systems. |
| JEDEC-compliant voltage standards | Fully compliant with JESD8-12 through JESD8-B - Validated interoperability across 0.8 V to 3.6 V logic families. |
Applications
| Industrial Sensor Interface | Low-Power Microcontroller 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 |
|---|---|---|---|
| 74LVC3G34GW,125 | Higher ICC (max 40 μA), no Schmitt inputs, wider VCC range (1.65–5.5 V) | Lacks input hysteresis; unsuitable for noisy or slow-edge sources | Select only if interfacing clean CMOS signals above 1.65 V and higher drive strength (24 mA) is required. |
| SN74AUP3G34DCUR | VSSOP8 package (3.0 × 2.3 mm), same electrical specs, no thermal pad | Larger footprint; less suitable for ultra-dense PCB layouts | Choose when hand-soldering or legacy board compatibility with VSSOP8 is prioritized over miniaturization. |
Compared with 74LVC3G34GW,125 and SN74AUP3G34DCUR, the 74AUP3G34GT115 uniquely combines Schmitt-trigger inputs, sub-1 μA ICC, and XSON8's 1.0 × 1.95 mm footprint-making it optimal for noise-prone, space-constrained, and battery-sensitive designs where deterministic input behavior and minimal leakage are mandatory.

FAQ
What is the maximum allowable input voltage for the 74AUP3G34GT115?
The 74AUP3G34GT115 accepts input voltages up to 3.6 V regardless of VCC level-enabling safe interfacing with higher-voltage signals (e.g., 3.3 V outputs) even when powered from 1.2 V or 1.8 V rails. This tolerance is explicitly specified in Table 6 (Recommended Operating Conditions) and validated per JEDEC standards.
Does the 74AUP3G34GT115 support true bidirectional operation?
No, the 74AUP3G34GT115 is a unidirectional non-inverting buffer only-inputs (1A/2A/3A) accept signals and outputs (1Y/2Y/3Y) drive loads. It lacks bus-hold, direction control, or tri-state capability. Each channel operates independently in one direction, as confirmed by the functional diagram and truth table in Section 7.
How does the IOFF feature behave during power-down of the 74AUP3G34GT115?
When VCC drops to 0 V, the IOFF circuitry forces all three outputs (1Y/2Y/3Y) into high-impedance state, limiting power-off leakage current to ±0.75 μA max (per Table 7). This prevents back-current flow from externally driven outputs into the unpowered device, protecting upstream drivers and maintaining system-level power domain isolation.
Can the 74AUP3G34GT115 be used with 0.8 V supply in production systems?
Yes-the 74AUP3G34GT115 is fully characterized and guaranteed down to 0.8 V supply across -40 °C to +125 °C, including propagation delay (14.9 ns typ), VIH/VIL thresholds, and output drive capability. This makes it suitable for emerging ultra-low-voltage microcontrollers and energy-harvesting applications where supply rails operate near threshold voltage.
What is the thermal performance difference between the GT and GX package variants of the 74AUP3G34?
The 74AUP3G34GT (SOT833-1, XSON8) has a total power dissipation limit of 250 mW with 3.1 mW/K derating above 68 °C, while the 74AUP3G34GX (SOT1233-2, X2SON8) offers enhanced thermal performance: 300 mW limit with 7.7 mW/K derating above 118 °C. The GX variant is optimized for higher ambient or power-dense layouts, whereas GT balances miniaturization and standard thermal handling.
