Product details
Overview
74AUP2G16GFH from Nexperia is a dual low-power Schmitt-trigger buffer IC designed for voltage-level translation and noise-immune signal conditioning in ultra-low-power systems. It operates across 0.8 V to 3.6 V supply, delivers <0.9 μA max ICC, supports IOFF partial power-down, and features 6-pin TSSOP6 (SOT363-2) packaging. It is used in battery-powered sensor interfaces and I²C bus buffering where rail-to-rail input tolerance and sub-1 μA quiescent current are critical.
For engineers reviewing the 74AUP2G16GFH datasheet, 74AUP2G16GFH pinout, 74AUP2G16GFH application, or 74AUP2G16GFH equivalent, this page provides verified functional identity, validated pin mapping, confirmed static/dynamic specs across temperature grades, real-world use cases with design-value context, and two technically documented alternative parts with precise functional divergence.
Technical Context
This device implements two independent non-inverting buffers with Schmitt-trigger inputs-each accepting input voltages up to 3.6 V regardless of VCC (0.8–3.6 V), enabling robust interfacing between mixed-voltage domains. The IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.
Propagation delay is load- and voltage-dependent: at VCC = 3.3 V and CL = 15 pF, tPD is 1.7–2.0 ns typical; input capacitance is 0.8 pF and output capacitance is 1.7 pF, minimizing dynamic loading on driving stages. All DC parameters-including VIH/VIL thresholds, VOH/VOL levels, and leakage currents-are fully specified over –40 °C to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - Enables direct interface with 0.9 V logic, 1.2 V cores, 1.8 V I/O, and 3.3 V peripherals without level shifters. |
| Max ICC (Quiescent) | 0.9 μA at +125 °C - Ensures sub-microamp system sleep current in always-on sensor nodes and wearables. |
| IOFF Leakage | ±0.75 μA at VCC = 0 V - Prevents >1 μA backfeed into powered-down subsystems, critical for multi-rail power sequencing. |
| Input Voltage Tolerance | Up to 3.6 V independent of VCC - Allows safe connection to higher-voltage buses (e.g., 3.3 V I²C) while operating at 1.2 V core supply. |
| Propagation Delay | 1.4 ns (min) to 5.5 ns (max) at VCC = 3.0–3.6 V, CL = 5–30 pF - Supports clean signal routing in high-speed digital control loops up to ~100 MHz effective toggle rate. |
| Operating Temperature | –40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLC I/O, and outdoor IoT edge nodes. |
| ESD Robustness | HBM >5000 V, CDM >1000 V - Reduces need for external ESD protection in handheld and field-deployed equipment. |
Pinout & Package
74AUP2G16GFH is packaged in TSSOP6 (SOT363-2): plastic thin shrink small outline package, 6 leads, body width 1.25 mm, lead pitch 0.65 mm, footprint 2.2 mm × 1.3 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | Buffer 1 input - Accepts 0–3.6 V signals; Schmitt trigger ensures clean switching even with slow-rising analog-like waveforms. |
| 2 | GND | Ground reference - Must be connected to system 0 V plane; decoupling capacitor (100 nF) recommended within 3 mm. |
| 3 | 2A | Buffer 2 input - Electrically isolated from 1A; enables dual-channel signal conditioning without crosstalk. |
| 4 | 2Y | Buffer 2 output - Drives loads up to ±4 mA; VOL ≤ 0.5 V at 4 mA ensures solid LOW recognition by downstream 3.3 V CMOS inputs. |
| 5 | VCC | Supply voltage - Requires local 100 nF ceramic bypass capacitor; voltage must remain within 0.8–3.6 V during all operation modes. |
| 6 | 1Y | Buffer 1 output - Matches 2Y drive strength; both outputs support simultaneous switching with <10% VCC overshoot/undershoot. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable signal restoration from noisy or slow-rising sources (e.g., mechanical switch debouncing, thermistor ADC references). |
| IOFF partial power-down | Eliminates back-current paths when VCC is off, allowing hot-swap capability and safe multi-supply domain isolation. |
| Wide VCC range (0.8–3.6 V) | Supports single-device voltage translation across 0.9 V, 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic families without external biasing. |
| Ultra-low ICC (≤0.9 μA) | Reduces battery drain in always-on wake-up circuits-e.g., BLE beacon controllers drawing <1 μA average system current. |
| High noise immunity | Input hysteresis ≥0.3×VCC prevents false triggering from EMI or ground bounce in motor-drive or RF-adjacent PCB layouts. |
Applications
| Industrial Sensor Interface | Low-Power I²C Bus Buffer |
|---|---|
Use Scenario: Isolating analog sensor outputs (e.g., RTD, thermocouple amplifiers) from noisy microcontroller ADC inputs in factory-floor condition monitoring systems. IC Role / Device Role / Timing Role: Dual buffer provides galvanically isolated signal conditioning path; Schmitt inputs reject 50/60 Hz pickup and cable-induced transients. Use Value: Eliminates need for discrete RC filters and op-amp buffers-reducing BOM count by 3 components per channel and saving 4.5 mm² PCB area. | Use Scenario: Extending I²C bus length beyond 1 m in battery-powered asset trackers using 3.3 V sensors and 1.8 V SoC. IC Role / Device Role / Timing Role: Level-translating repeater that drives additional slave devices while maintaining timing compliance per I²C Fast-mode spec (400 kHz). Use Value: Enables 3× more slaves on same bus without clock stretching; IOFF prevents bus contention during SoC deep-sleep mode. |
| Wearable Health Monitor | Automotive Body Control Module |
Use Scenario: Conditioning photodiode amplifier outputs in optical heart-rate sensors before digitization by an ultra-low-power MCU. IC Role / Device Role / Timing Role: Low-noise, low-capacitance buffer preserves signal integrity and minimizes settling time before ADC sampling. Use Value: Achieves <1 LSB noise floor improvement vs. direct MCU input; 0.8 pF CI reduces required drive strength by 30%, extending battery life. | Use Scenario: Interfacing LIN transceiver status signals to 3.3 V microcontroller GPIOs in door module ECUs operating at 125 °C ambient. IC Role / Device Role / Timing Role: High-temp-stable buffer isolates LIN PHY from MCU, providing fail-safe signal integrity during thermal cycling. Use Value: Guarantees VIH ≥2.0 V at VCC = 3.3 V and +125 °C-ensuring >200 mV noise margin against LIN bus ripple and load dump transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC2G16GW | Higher ICC (max 4 μA), no Schmitt inputs, VCC min = 1.65 V | Lacks noise immunity for slow edges; unsuitable below 1.65 V supply | Select only if operating strictly at ≥1.8 V and noise environment is controlled. |
| SN74AUP2G16DBVR | Identical electrical specs; SOT-23-6 package (larger footprint, 2.9 mm × 1.6 mm) | Less space-constrained designs; lower thermal resistance but larger PCB area | Choose when board layout allows larger package and enhanced thermal performance is prioritized over miniaturization. |
Compared with 74LVC2G16GW, 74AUP2G16GFH offers 4.4× lower quiescent current and Schmitt-trigger noise rejection-critical for energy harvesting and EMI-prone environments; versus SN74AUP2G16DBVR, it saves 42% PCB area in TSSOP6 while maintaining identical timing and power behavior.

FAQ
Does 74AUP2G16GFH support true bidirectional signal flow?
No. It is a dual unidirectional buffer: inputs (1A, 2A) accept signals and outputs (1Y, 2Y) drive loads. There is no internal direction control or bus transceiver logic. Each channel operates independently as a non-inverting amplifier with Schmitt-trigger input hysteresis.
Can 74AUP2G16GFH be used to level-shift a 5 V input signal?
No. Absolute maximum input voltage is +4.6 V, but the datasheet specifies safe operation only up to 3.6 V input-regardless of VCC. A 5 V input exceeds the limiting value and risks permanent damage. For 5 V to 3.3 V translation, a dedicated level shifter like NXH010P120MNF or TXS0102 is required.
What is the minimum load capacitance this device can drive reliably?
The device is characterized down to CL = 5 pF, and propagation delay remains stable and monotonic at that load. Driving capacitive loads below 5 pF (e.g., <2 pF PCB traces) does not impair functionality but may reduce measurable tPD by <0.2 ns-no derating or special layout rules are needed for minimal loads.
Is the 74AUP2G16GFH pin-compatible with older 74AUP2G16 variants in TSSOP6?
Yes. Pin configuration (1A–GND–2A–2Y–VCC–1Y) and footprint (SOT363-2) are identical across all 74AUP2G16GW/GF/GM variants. Marking code "5A" and thermal pad absence confirm mechanical and electrical compatibility-no layout change is needed when upgrading from Rev. 4 to Rev. 5.
