Product details
Overview
74AUP3G17DCH from Nexperia is a low-power triple Schmitt trigger buffer IC designed for signal conditioning in ultra-low-voltage digital systems. It provides three independent hysteresis-input buffers operating across 0.8 V to 3.6 V supply, with input hysteresis voltage (VH) up to 1.31 V at 3.0 V VCC, ICC ≤ 0.9 μA max, and propagation delay as low as 1.5 ns at 3.0 V with 5 pF load - enabling clean edge regeneration in battery-powered sensor interfaces and I²C bus level-shifting applications.
For engineers reviewing the 74AUP3G17DCH datasheet, 74AUP3G17DCH pinout, 74AUP3G17DCH application, or 74AUP3G17DCH equivalent, this device delivers verified Schmitt-trigger noise immunity, IOFF-enabled partial power-down capability, and guaranteed operation from –40 °C to +125 °C in VSSOP8 packaging - critical for industrial IoT node design, wearables power sequencing, and mixed-voltage logic interfacing where signal integrity and static current budget are constrained.
Technical Context
The 74AUP3G17DCH implements three independent Schmitt-trigger input stages feeding standard CMOS output buffers, each with asymmetric switching thresholds (VT+ and VT–) defined per supply voltage to ensure ≥0.07 V hysteresis down to 0.8 V VCC. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V while inputs/outputs remain biased up to 3.6 V.
Dynamic performance is characterized across four load capacitances (5–30 pF) and five VCC ranges (0.8–3.6 V), with propagation delay tightly specified from 1.5 ns (3.0–3.6 V, CL = 5 pF) to 3.1 ns (3.0–3.6 V, CL = 30 pF); input capacitance is 1.1 pF and output capacitance is 1.7 pF, minimizing loading on driving sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - supports direct interface with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters |
| ICC (max) | 0.9 μA at 25 °C - enables multi-year battery life in always-on sensor nodes and real-time clock supervisors |
| VH (hysteresis) | Up to 1.31 V at VCC = 3.0 V - rejects >1.3 V peak-to-peak noise on slow-rising signals like thermistor or potentiometer outputs |
| tpd (min) | 1.5 ns at VCC = 3.0 V, CL = 5 pF - ensures sub-2 ns timing margin for 300+ MHz clock domain synchronization |
| IOFF Leakage | ±0.75 μA max at VCC = 0 V - prevents cross-conduction and bus contention during hot-swap or partial system shutdown |
| ESD Rating | HBM >5000 V, CDM >1000 V - sustains handling and board-level ESD events without latch-up or parametric shift |
| Operating Temp | –40 °C to +125 °C - qualified for under-hood automotive modules, industrial motor drives, and outdoor base stations |
Pinout & Package
VSSOP8 package (SOT765-1): plastic very thin shrink small outline package, 8 leads, 2.3 mm body width, 0.5 mm pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A | Independent Schmitt-trigger inputs | Accept DC-coupled analog or digital signals up to 3.6 V; each has unique VT+/VT– thresholds for noise rejection |
| 1Y, 2Y, 3Y | CMOS-compatible buffered outputs | Drive 5 pF loads with <2 ns delay; rail-to-rail swing (VOL ≤ 0.5 V, VOH ≥ 2.3 V at 3.0 V) |
| VCC | Supply voltage input | Single supply powers all three channels; IOFF active when VCC = 0 V |
| GND | Reference ground | Common return for all inputs, outputs, and internal biasing; decoupling capacitor required within 3 mm |
Key Features
| Feature | Design Value |
|---|---|
| Triple Schmitt-trigger architecture | Three independent hysteresis-input buffers in one die - reduces PCB area vs. discrete solutions and eliminates inter-channel skew |
| IOFF partial power-down | Outputs go high-impedance when VCC = 0 V, preventing backfeed current into powered subsystems during sleep or fault isolation |
| Ultra-low ICC | 0.9 μA max supply current - allows integration into always-on wake-up circuits without depleting coin-cell batteries |
| Wide VCC hysteresis scaling | VH tracks VCC from 0.07 V (0.8 V supply) to 1.31 V (3.0 V supply) - maintains consistent noise margin across voltage domains |
| High noise immunity | Input threshold separation exceeds 1.2× typical TTL noise margin - suppresses glitches from EMI-coupled traces or mechanical switch bounce |
Applications
| Industrial Sensor Interface | I²C Bus Level Translation |
|---|---|
Use Scenario: Conditioning slow-rising analog sensor outputs (e.g., RTD, thermistor, or photoresistor) before ADC sampling in programmable logic controllers. IC Role / Device Role / Timing Role: Schmitt-trigger buffer converts noisy, millisecond-scale analog ramps into clean, jitter-free digital edges synchronized to system clock.

IC Role / Device Role / Timing Role: Three independent buffers isolate SDA, SCL, and reset lines while preserving rise/fall time integrity across voltage domains. Use Value: Enables bidirectional level translation without external pull-ups or direction control, reducing BOM count and layout complexity. |
| Wearable Power Sequencing | Automotive Body Control Module |
Use Scenario: Managing power-up sequence of BLE SoC, PMIC, and environmental sensors in hearables using single lithium-polymer cell (2.7–4.2 V). IC Role / Device Role / Timing Role: Buffers monitor battery voltage thresholds and enable/disable regulators via clean, hysteresis-controlled enable signals. Use Value: Prevents oscillation during brown-out conditions and extends functional uptime by 12–18% versus comparator-based solutions. | Use Scenario: Debouncing door lock actuator feedback switches and window position sensors exposed to automotive EMI environments. IC Role / Device Role / Timing Role: Converts slow, noisy mechanical switch closures into deterministic logic-level pulses for MCU GPIO capture.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt trigger buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G17DCUR | Higher ICC (10 μA typ), wider VCC (1.65–5.5 V), no IOFF, 1.5 ns tpd at 3.3 V | Lacks power-down isolation; unsuitable for partial shutdown architectures | Select only if system operates exclusively above 1.65 V and IOFF is not required |
| 74LVC1G17GV | Single-channel, same VCC range (1.65–5.5 V), no IOFF, 3.2 ns tpd at 3.3 V, SOT753 package | Requires three separate packages for triple functionality; higher board area and assembly cost | Choose only when space constraints prohibit 8-pin packages or channel count is variable |
Compared with SN74LVC3G17DCUR and 74LVC1G17GV, the 74AUP3G17DCH uniquely combines ultra-low ICC (<1 μA), IOFF-enabled power gating, and triple integration in VSSOP8 - making it the sole option for energy-constrained, mixed-voltage, and hot-pluggable designs requiring guaranteed hysteresis across 0.8–3.6 V.

FAQ
What is the maximum input voltage the 74AUP3G17DCH can tolerate when VCC = 0 V?
The 74AUP3G17DCH inputs accept voltages up to 3.6 V regardless of VCC state, per datasheet Table 5 (VI limit: –0.5 V to +4.6 V) and Table 6 (recommended VI range: 0 V to 3.6 V). This enables safe "live insertion" into powered buses during system maintenance or hot-swap operations without damage.
Does the 74AUP3G17DCH support true bidirectional signal conditioning?
No - the 74AUP3G17DCH is a unidirectional buffer (input → output only) with fixed Schmitt-trigger input and CMOS output stages. It does not implement bus transceivers or direction-control logic; bidirectional use requires external circuitry or a dedicated transceiver IC.
How does the hysteresis voltage (VH) scale with supply voltage?
VH scales approximately linearly with VCC: from 0.07 V at 0.8 V VCC to 1.31 V at 3.0 V VCC. Per Table 11, VH = VT+ − VT− is guaranteed ≥0.53 V at 1.1 V VCC and ≥0.92 V at 2.3 V VCC, ensuring consistent noise margin across the full operating range.
Can the 74AUP3G17DCH drive a 50 pF load reliably?
The datasheet specifies dynamic characteristics only up to 30 pF (Table 8). While functional at 50 pF, propagation delay increases beyond 7.5 ns (extrapolated from 30 pF data at 3.0 V), and output rise/fall times degrade. For 50 pF loads, verify timing margins in final layout and consider adding series termination or selecting a higher-drive buffer.
