Product details
Overview
74AUP1G17GV from Nexperia is a single-channel CMOS Schmitt-trigger buffer optimized for low-voltage, low-power signal conditioning in battery-powered and noise-prone digital interfaces. It operates across 0.8 V to 3.6 V supply, delivers ±20 mA output drive, features IOFF partial power-down protection, and ensures robust noise immunity with hysteresis (VH = 0.79–1.31 V at VCC = 3.0 V) - used in I²C bus level-shifting, sensor signal cleanup, and microcontroller GPIO debouncing.
For engineers reviewing the 74AUP1G17GV datasheet, 74AUP1G17GV pinout, 74AUP1G17GV application, or 74AUP1G17GV equivalent, key selection criteria include its 5-pin SC-74A (SOT753) package, guaranteed operation from –40 °C to +125 °C, sub-1 μA max ICC at 25 °C, Schmitt-trigger input thresholds (VT+ = 1.88–2.32 V, VT– = 0.88–1.24 V at VCC = 3.0 V), and IOFF-enabled system-level power sequencing compliance.
Technical Context
The device implements a single non-inverting Schmitt-trigger buffer with asymmetric input hysteresis to reject slow-rising or noisy signals. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down - critical for hot-swap and multi-rail systems.
It supports JEDEC-compliant voltage standards across five VCC ranges (0.8–1.3 V, 0.9–1.65 V, 1.2–1.95 V, 1.8–2.7 V, 2.7–3.6 V) and maintains stable propagation delay (tpd = 1.5–4.0 ns at CL = 5 pF, VCC = 3.0–3.6 V) and low dynamic power dissipation (CPD = 4.0 pF at VCC = 3.0–3.6 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - enables direct interfacing with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Max ICC (Static) | 1.4 μA at –40 °C to +125 °C - ensures negligible quiescent drain in always-on sensor nodes or real-time clock circuits. |
| IOFF Leakage | ±0.75 μA at VCC = 0 V - prevents cross-conduction and backfeed in powered-down subsystems. |
| Hysteresis Voltage (VH) | 0.79–1.31 V at VCC = 3.0 V - provides ≥400 mV noise margin for reliable edge detection on slow analog-like inputs. |
| Propagation Delay (tpd) | 1.5–4.0 ns at CL = 5 pF, VCC = 3.0–3.6 V - supports >200 MHz signal conditioning in high-speed control loops. |
| ESD Robustness | HBM >5000 V, CDM >1000 V - eliminates need for external ESD protection in handheld and industrial I/O designs. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and outdoor IoT deployments. |
Pinout & Package
74AUP1G17GV uses the SC-74A (SOT753) surface-mount package: plastic, 5-lead, body size 2.7 mm × 1.3 mm × 1.1 mm, with gull-wing leads and pin 1 index marked by a dot or bevel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | n.c. | No internal connection - left unconnected; no routing or grounding required. |
| 2 | A | Schmitt-trigger input - accepts slow or noisy signals; threshold hysteresis rejects glitches < 400 mV. |
| 3 | GND | Ground reference - must be low-impedance return path for both input and output current. |
| 4 | Y | Inverted-buffered output - drives CMOS loads up to ±20 mA; compatible with 1.2–3.3 V logic families. |
| 5 | VCC | Power supply - supplies core logic and output stage; IOFF activates automatically if pulled to 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (0.8–3.6 V) | Eliminates separate LDOs for mixed-voltage SoC peripherals - e.g., connects 1.8 V sensor to 3.3 V MCU GPIO directly. |
| IOFF partial power-down | Prevents destructive back-current flow when VCC is off but A or Y remains biased - essential for PCIe hot-plug and USB-C PD arbitration. |
| Overvoltage-tolerant inputs | Accepts up to 3.6 V on A pin regardless of VCC setting - simplifies interface to legacy 3.3 V buses without clamping diodes. |
| Low noise overshoot/undershoot | <10 % of VCC - reduces EMI and eliminates need for series termination resistors in space-constrained PCB layouts. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - guarantees robust operation in high-noise factory automation environments. |
Applications
| Industrial Sensor Interface | I²C Bus Signal Conditioning |
|---|---|
Use Scenario: Cleaning slow-rising analog sensor outputs (e.g., thermistor, potentiometer) before digitization by an ADC or microcontroller. IC Role / Device Role / Timing Role: Schmitt-trigger buffer converts noisy, slow analog edges into clean digital transitions with defined hysteresis. Use Value: Eliminates software debouncing overhead and prevents false triggers caused by EMI or mechanical contact bounce. | Use Scenario: Strengthening weak pull-up signals on I²C SDA/SCL lines in multi-master embedded systems with long traces. IC Role / Device Role / Timing Role: Non-inverting buffer isolates and regenerates open-drain bus signals while preserving timing integrity.

| Microcontroller GPIO Debouncing | Power Sequencing Control Logic |
Use Scenario: Debouncing mechanical pushbuttons or rotary encoders connected directly to MCU GPIO pins. IC Role / Device Role / Timing Role: Input hysteresis filters contact bounce; IOFF ensures safe state during MCU reset or sleep mode. Use Value: Reduces firmware complexity and eliminates need for RC filters or polling-based debounce algorithms. | Use Scenario: Enabling/disabling power rails in multi-stage DC-DC converter sequences where one rail must stabilize before enabling the next. IC Role / Device Role / Timing Role: Buffer gates enable signals between isolated voltage domains with precise timing control and power-down isolation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt-trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G17DBVR | Wider VCC range (1.65–5.5 V); higher ICC (max 10 μA); no IOFF; lower hysteresis (VH ≈ 0.5 V at 3.3 V). | Not suitable for sub-1.65 V operation or partial power-down systems; requires external isolation for hot-swap. | Select when interfacing with 5 V logic or when IOFF is unnecessary and cost is primary constraint. |
| 74LVC1G17GW | Same 5-pin TSSOP5 (SOT353) package; identical functional spec; rated only to +85 °C (not +125 °C); no IOFF. | Limited to commercial-temperature applications; lacks power sequencing safety for automotive or industrial use. | Select only for cost-sensitive consumer electronics with ambient temperature < 85 °C and no partial power-down requirement. |
Compared with SN74LVC1G17DBVR and 74LVC1G17GW, the 74AUP1G17GV uniquely combines ultra-low ICC (<1.4 μA), full –40 °C to +125 °C qualification, and IOFF - making it the sole choice for extended-temperature, battery-critical, and hot-swap-safe designs.

FAQ
Can 74AUP1G17GV operate reliably at 0.85 V supply?
Yes. The device is fully specified down to 0.8 V per JEDEC JESD8-12, with guaranteed functionality including VOH ≥ VCC − 0.1 V, VOL ≤ 0.1 V, and tpd ≤ 10.6 ns (CL = 5 pF) at VCC = 0.85 V. This enables direct integration with emerging ultra-low-voltage MCUs and energy-harvesting systems.
Does the n.c. pin (Pin 1) require PCB routing or grounding?
No. Pin 1 is internally not connected and must remain unconnected on the PCB. Routing or grounding this pin may cause mechanical stress or unintended coupling; Nexperia's package drawings explicitly define it as "n.c." with no electrical function or thermal role.
How does IOFF behave when VCC is ramping during power-up?
IOFF activates only when VCC falls below ~0.2 V. During controlled power-up, the output remains high-impedance until VCC exceeds the minimum operating threshold (~0.8 V), then transitions to active drive. No external enable control is needed - the feature is fully automatic and integrated into the core logic.
What is the maximum capacitive load the Y output can drive while maintaining timing specs?
The device is characterized up to CL = 30 pF, with tpd ≤ 7.5 ns at VCC = 3.0–3.6 V. Driving >30 pF increases propagation delay nonlinearly and may degrade edge monotonicity; for loads >50 pF, a second-stage buffer or series resistor is recommended to maintain signal integrity and avoid ringing.
