Product details
Overview
74AXP1G14GMH from Nexperia is a single-channel Schmitt trigger inverter IC designed for signal conditioning in ultra-low-power digital systems. It operates across 0.7 V to 2.75 V supply, delivers jitter-free output from slow-rising inputs, features IOFF partial power-down protection, and is specified for -40 °C to +85 °C industrial environments - used in battery-powered sensor interfaces and I²C bus level-shifting circuits.
For engineers reviewing the 74AXP1G14GMH datasheet, 74AXP1G14GMH pinout, 74AXP1G14GMH application, or 74AXP1G14GMH equivalent, key selection criteria include its sub-1 μA static ICC at 85 °C, 0.5 pF input capacitance, Schmitt hysteresis (0.2–1.0 V), IOFF-enabled backflow prevention, and XSON6 (SOT886) 6-terminal package compatibility with high-density PCB layouts.
Technical Context
This device implements a single inverting buffer with hysteresis to reject noise on slow-transitioning signals, enabling reliable logic-level restoration in mixed-voltage domains. Its IOFF circuit actively disables outputs during power-down, blocking reverse current flow when VCC = 0 V while inputs/outputs remain biased up to 2.75 V.
The Schmitt trigger thresholds are voltage-scalable: VT+ ranges from 0.3VCC to 0.9 V and VT− from 0.2VCC to 0.7 V depending on VCC, delivering consistent noise immunity across 0.7–2.75 V operation. Propagation delay is as low as 1.2 ns (typ.) at VCC = 2.7 V with 15 pF load, and transition time remains under 1.0 ns at full rail.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 0.7 V to 2.75 V - enables direct interface with 0.8 V, 1.2 V, 1.8 V, and 2.5 V logic domains without level shifters. |
| Static Supply Current | 0.6 μA max at 85 °C - ensures negligible battery drain in always-on sensor nodes and IoT wake-up circuits. |
| Input Capacitance | 0.5 pF typical - minimizes loading on high-impedance sources like crystal oscillator outputs or capacitive touch sensors. |
| Hysteresis Voltage | 0.2 V to 1.0 V - provides robust noise margin against EMI in noisy industrial control signal paths. |
| IOFF Leakage | ±0.1 μA max at VCC = 0 V - prevents cross-talk and backfeed in multi-rail systems during partial power-down sequencing. |
| Propagation Delay | 1.2 ns typical at VCC = 2.7 V, CL = 15 pF - supports clean edge generation for clock clean-up and debounce in real-time subsystems. |
| Operating Temperature | -40 °C to +85 °C - validated for deployment in industrial automation controllers and automotive body electronics (non-safety). |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT886); no leads; 6 terminals; body dimensions 1.0 × 1.45 × 0.5 mm; thermal padless; moisture sensitivity level MSL1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Not connected | Electrically isolated; no internal connection - must be left floating or grounded per layout best practice. |
| 2 | Data input (A) | Schmitt-triggered inverter input accepting 0–2.75 V; tolerant of overvoltage beyond VCC. |
| 3 | Ground (GND) | Reference node for all I/O and supply; requires low-inductance connection to system ground plane. |
| 4 | Data output (Y) | Inverted, rail-to-rail CMOS output; drives loads up to ±20 mA; supports IOFF disable when VCC = 0 V. |
| 5 | Not connected | Electrically isolated; no internal connection - must be left floating or grounded per layout best practice. |
| 6 | Supply (VCC) | Primary power rail; IOFF circuit activates automatically when VCC drops below ~0.2 V, isolating Y and A terminals. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 0.7–2.75 V operation enables seamless integration into heterogeneous voltage domains including sub-1 V logic and legacy 2.5 V systems. |
| IOFF partial power-down | Prevents damaging back-current flow during hot-insertion or asymmetric power sequencing in multi-supply boards. |
| Low input/output capacitance | 0.5 pF CI and 1.0 pF CO minimize signal distortion and timing skew in high-speed trace routing and RF-adjacent layouts. |
| JEDEC-compliant voltage standards | Fully compliant with JESD8-12A.01 through JESD8-5A.01 - certified for interoperability across 1.1 V to 2.7 V logic families. |
| High ESD robustness | HBM > 2 kV and CDM > 1000 V - reduces need for external TVS protection in handheld and field-deployable equipment. |
Applications
| Industrial Sensor Interface | I²C Bus Level Translation |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schmitt trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G14DBVR | Wider VCC range (1.65–5.5 V); higher ICC (10 μA typ.); no IOFF; 5-pin SOT-23 package. | Requires ≥1.65 V supply; unsuitable for sub-1 V systems or partial power-down designs. | Select when interfacing with 3.3 V/5 V logic and IOFF is not required. |
| 74LVC1G14GW,125 | Same XSON6 package; identical pinout; but lacks IOFF and has higher ICC (2 μA max at 85 °C). | Cannot safely isolate during VCC ramp-down; may allow back-current in multi-rail hot-swap scenarios. | Choose only if cost is primary constraint and IOFF functionality is unused in target design. |
Compared with SN74LVC1G14DBVR and 74LVC1G14GW,125, the 74AXP1G14GMH uniquely supports sub-1 V operation and IOFF-enabled power sequencing - critical for energy-harvesting nodes and USB-C port controllers where supply staging and leakage control are mandatory.

FAQ
Does 74AXP1G14GMH support true bidirectional level shifting?
No - it is a unidirectional inverter. For bidirectional I²C translation, two units are used in push-pull configuration with external pull-ups. The device does not contain internal pass transistors or direction control; its IOFF feature only disables output drive during power-down, not signal directionality.
What is the minimum recommended load capacitance for stable Schmitt operation?
No minimum load capacitance is required. The device functions correctly with open-drain or unterminated outputs. However, for optimal noise immunity in high-noise environments, a 10–22 pF capacitor to GND on the output is recommended to dampen ringing without degrading propagation delay beyond 2.5 ns.
Can pin 1 (n.c.) be tied to GND or VCC for improved thermal performance?
No - pin 1 is electrically unconnected and internally isolated. Connecting it to GND or VCC provides no thermal or electrical benefit and risks violating the SOT886 package's mechanical stress limits. Thermal dissipation relies solely on copper pad area under the exposed die paddle (not present in this variant) and PCB trace conduction.
Is the 74AXP1G14GMH qualified for automotive applications?
No - it is specified for industrial temperature range (-40 °C to +85 °C) and carries no AEC-Q200 qualification. Nexperia offers automotive-grade variants (e.g., 74AXP1G14GMHE) with extended testing and PPAP documentation; this GMH suffix denotes standard industrial grade only.
