Product details
Overview
74AXP2G14GSH from Nexperia is a dual 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 input edges, and features IOFF partial power-down protection. Used in battery-powered sensor interfaces and level-shifting I²C/SPI bus buffers.
For engineers reviewing the 74AXP2G14GSH datasheet, 74AXP2G14GSH pinout, 74AXP2G14GSH application, or 74AXP2G14GSH equivalent, key selection criteria include its sub-1 μA static ICC at 85 °C, 0.5 pF input capacitance, Schmitt-trigger hysteresis (0.2–1.0 V), and XSON6 package compatibility with high-density PCB layouts.
Technical Context
This device implements two independent Schmitt-trigger inverters in a single die, each with asymmetric threshold voltages (VT+ and VT−) enabling noise-immune signal regeneration. Its IOFF circuit actively disables outputs during VCC = 0 V, preventing backflow current in mixed-voltage partial-power-down systems.
Dynamic performance is defined by propagation delay (1.0–126 ns depending on VCC and load), transition time ≤1.0 ns at 2.7 V, and low CPD (2.3–2.9 pF) ensuring minimal dynamic power dissipation in high-frequency switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 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 (ICC) | ≤1.0 μA at 85 °C - ensures negligible quiescent drain in always-on sensor nodes and real-time clock backup paths |
| Input Capacitance (CI) | 0.5 pF typical - minimizes loading on high-impedance sources such as crystal oscillator outputs or capacitive touch sensors |
| Hysteresis Voltage (VH) | 0.2 V to 1.0 V (VCC-dependent) - provides robust noise margin against EMI in industrial control feedback loops |
| IOFF Leakage Current | ≤0.5 μA at VCC = 0 V - prevents unintended current paths when one rail is powered down in multi-rail SoC subsystems |
| Propagation Delay (tpd) | 1.2 ns typical at VCC = 2.7 V - supports clean edge generation for timing-critical reset synchronization |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial-grade embedded controllers and automotive body electronics |
Pinout & Package
XSON6 plastic extremely thin small outline package (no leads); 6-terminal surface-mount; body dimensions 1.0 × 1.0 × 0.35 mm (SOT1202). Compatible with standard reflow profiles and 0.4 mm pitch PCB routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First inverter input - accepts up to 2.75 V regardless of VCC; Schmitt-trigger threshold adapts to supply voltage |
| 2 | GND | Digital ground reference - must be connected directly to system ground plane to maintain noise immunity |
| 3 | 2A | Second inverter input - electrically isolated from 1A; enables dual independent signal conditioning paths |
| 4 | 2Y | Second inverter output - drives CMOS loads up to ±8 mA; VOH/VOL specified across full VCC range |
| 5 | VCC | Power supply input - supports decoupling with 100 nF ceramic capacitor placed within 2 mm of pin |
| 6 | 1Y | First inverter output - complements 1A with sharp edge transitions; used for clock cleanup or debounced switch inputs |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (0.7–2.75 V) | Eliminates need for external regulators in multi-voltage IoT nodes using 0.8 V core and 1.8 V I/O rails |
| IOFF partial power-down | Enables safe hot-swap and rail sequencing in modular systems where VCC may be absent while other signals remain active |
| Low input capacitance (0.5 pF) | Preserves signal integrity on long traces or high-Z sensor outputs without requiring buffer amplification |
| HBM ESD rating >2000 V | Reduces need for external TVS diodes in handheld medical devices and portable test equipment |
| Latch-up immunity >100 mA | Ensures robustness against transient overvoltage events in factory automation PLC I/O modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schmitt-trigger inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G14DBVR | Wider VCC range (1.65–5.5 V); higher ICC (10 μA max); no IOFF | Requires external isolation for partial power-down; unsuitable for sub-1.65 V operation | Select when interfacing legacy 3.3 V/5 V peripherals and IOFF is not required |
| 74LVC2G14GM | Same XSON6 package; higher minimum VCC (1.65 V); 10× higher static ICC (10 μA) | Cannot operate below 1.65 V; less suitable for energy-harvesting or coin-cell designs | Select when design uses ≥1.65 V rails and cost is prioritized over ultra-low ICC |
Compared with SN74LVC2G14DBVR and 74LVC2G14GM, the 74AXP2G14GSH uniquely supports 0.7 V operation and sub-1 μA static current-critical for battery lifetime in always-on edge nodes-while maintaining identical XSON6 footprint and Schmitt functionality.

FAQ
Does 74AXP2G14GSH support true bidirectional level shifting?
No. The 74AXP2G14GSH is a unidirectional inverter with fixed input and output terminals. While its inputs accept voltages up to 2.75 V irrespective of VCC, it cannot pass signals from output to input. For bidirectional level translation, a dedicated bus switch or dual-supply translator like NXSA1041 must be used.
What is the maximum capacitive load this device can drive reliably?
The device is characterized up to 140 pF load capacitance per output, with propagation delay increasing predictably (e.g., 12 ns at 140 pF, VCC = 1.2 V). Driving >140 pF risks violating setup/hold times in synchronous systems; for heavier loads, add a dedicated buffer stage or reduce trace length and parasitic capacitance.
Can 74AXP2G14GSH be used with 3.3 V I/O signals?
No. Absolute maximum input voltage is +3.3 V, but recommended operating input voltage is limited to 0–2.75 V. Applying 3.3 V continuously exceeds specification and risks accelerated degradation. Use a resistive divider or level translator if interfacing with 3.3 V sources.
How does the IOFF feature behave when VCC = 0 V but input signals are present?
When VCC = 0 V, the IOFF circuit disables both outputs (1Y and 2Y), presenting high-impedance states. Input pins (1A, 2A) remain functional and tolerate 0–2.75 V, but no output is driven-preventing backfeed current into powered-down sections of the system.
