Product details

Overview

74AXP1G17GXH from Nexperia is a single-channel low-power Schmitt trigger buffer in X2SON5 (SOT1226-3) package with 5 terminals, operating from 0.7 V to 2.75 V supply, delivering 0.2 V to 1.0 V hysteresis and sub-3 ns propagation delay at 2.5 V, used for signal conditioning in battery-powered IoT sensors and ultra-low-voltage microcontroller I/O interfaces.

For engineers reviewing the 74AXP1G17GXH datasheet, 74AXP1G17GXH pinout, 74AXP1G17GXH application, or 74AXP1G17GXH equivalent, key selection criteria include its IOFF-enabled partial power-down capability, 0.5 pF input capacitance, ±0.1 μA static current at 85 °C, and guaranteed operation across –40 °C to +85 °C industrial temperature range.

Technical Context

This device implements a single non-inverting Schmitt trigger with asymmetric threshold hysteresis (VT+ and VT–), enabling clean digital edge regeneration from slow-rising analog or noisy signals. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.

Designed for multi-rail systems, it accepts input voltages up to 2.75 V independent of VCC and maintains defined logic states across its full 0.7 V–2.75 V supply range, with JEDEC-compliant voltage-level standards covering 1.1 V–2.7 V operation bands.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	0.7 V to 2.75 V - enables direct interface with sub-1 V logic domains and legacy 1.2/1.8/2.5 V rails without level shifters
Hysteresis Voltage (VH)	0.2 V to 1.0 V - provides noise immunity margin against EMI-induced glitches on long PCB traces or unshielded sensor lines
Propagation Delay (tpd)	1.1 ns to 3.3 ns - supports high-speed signal cleanup in real-time control loops with < 4 ns total latency
Input Capacitance (CI)	0.5 pF typical - minimizes loading on high-impedance sources like crystal oscillators or capacitive touch sensors
IOFF Leakage Current	±0.1 μA max at VCC = 0 V - prevents cross-talk and unintended biasing in powered-down subsystems
Operating Temperature	–40 °C to +85 °C - qualified for industrial automation, smart metering, and automotive body electronics (non-safety-critical)

Pinout & Package

X2SON5 (SOT1226-3) package: plastic thermal-enhanced extremely thin small outline, no leads, 5 terminals, body dimensions 0.8 mm × 0.8 mm × 0.32 mm, thermal pad exposed on bottom for improved heat dissipation in dense layouts.

Pin/Terminal	Circuit Role	Design Meaning
n.c.	No-connect terminal	Unused pad; must remain unconnected to avoid parasitic coupling or solder bridging
VCC	Positive supply rail	Primary power input; supplies internal logic and output drivers; requires local 100 nF decoupling
GND	Ground reference	Return path for all currents; must be connected to system ground plane with minimal impedance
A	Data input	Schmitt-triggered input accepting 0–2.75 V; tolerant of overvoltage relative to VCC
Y	Data output	Inverting-buffered output with rail-to-rail swing; drives CMOS loads up to 8 mA sink/source

Key Features

Feature	Design Value
IOFF Partial Power-Down	Disables output and blocks backflow current when VCC = 0 V - essential for hot-swap and multi-voltage domain isolation
Ultra-Low Static Current	0.6 μA maximum at 85 °C - extends battery life in always-on sensor nodes beyond 10 years
Sub-1 pF Input/Output Capacitance	CI = 0.5 pF, CO = 1.0 pF - preserves signal integrity in RF-adjacent or high-frequency sampling circuits
Multi-Voltage JEDEC Compliance	Validated per JESD8-12A.01 (1.1–1.3 V), JESD8-11A.01 (1.4–1.6 V), JESD8-7A (1.65–1.95 V), JESD8-5A.01 (2.3–2.7 V) - ensures interoperability across mixed-supply SoC designs
High-Noise Immunity	Minimum 0.2 V hysteresis at 0.75 V VCC - rejects >200 mV peak-to-peak noise on weak signal lines

Applications

Industrial Sensor Interface

Low-Power Microcontroller I/O

Use Scenario: Signal conditioning for analog-output temperature/humidity sensors feeding into ADC inputs of battery-powered edge nodes.

IC Role / Device Role / Timing Role: Schmitt trigger buffer cleans slow-rising thermistor-derived signals before digitization, eliminating metastability in sampling clocks.

Use Value: Enables reliable 12-bit ADC conversion without external RC filtering, reducing BOM count by one passive component per channel.

Use Scenario: Level-shifting and noise suppression between 0.8 V FPGA I/O banks and 1.8 V peripheral UART transceivers.

IC Role / Device Role / Timing Role: Single-gate buffer isolates mismatched voltage domains while preserving timing margins via sub-3 ns propagation.

Use Value: Eliminates need for discrete MOSFET translators, saving 0.5 mm² PCB area and simplifying layout routing near high-speed serial links.

Wearable Biometric Monitoring

Smart Energy Metering

Use Scenario: Debouncing mechanical switch inputs from heart-rate monitor buttons operating under variable battery voltage (0.9–2.4 V).

IC Role / Device Role / Timing Role: Schmitt input rejects contact bounce and ESD-induced transients while maintaining consistent threshold behavior across discharge curve.

Use Value: Achieves >99.9% switch recognition accuracy without firmware polling overhead or timer-based software debouncing.

Use Scenario: Isolating pulse outputs from utility meter flow sensors exposed to electromagnetic interference in distribution panels.

IC Role / Device Role / Timing Role: Input hysteresis suppresses 50/60 Hz magnetic coupling and switching noise from nearby relays or inverters.

Use Value: Reduces false pulse counting errors from 5–10 per hour to zero, meeting IEC 62053-21 Class 1 accuracy requirements.

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 (10 μA typ); no IOFF; SOT-23-5 package (1.6 × 2.8 mm)	Requires ≥1.65 V supply; unsuitable for sub-1 V systems or partial power-down architectures	Select when interfacing with 3.3 V or 5 V peripherals and board space permits larger footprint
74LVC1G17GW,125	Same XSON6 package (1.0 × 1.0 mm); identical 0.7–2.75 V range; lacks IOFF; 1.5× higher CPD (3.8 pF vs 2.5 pF)	No power-down isolation; higher dynamic power in burst-mode operation	Prefer for cost-sensitive designs where IOFF is not required and thermal budget allows +15% dynamic dissipation

Compared with SN74LVC1G17DBVR and 74LVC1G17GW,125, the 74AXP1G17GXH uniquely combines sub-1 V operation, IOFF protection, and X2SON5's 0.8 mm × 0.8 mm footprint-making it optimal for space-constrained, multi-rail, battery-operated systems requiring robust signal integrity.

FAQ

Does 74AXP1G17GXH support true bidirectional signal conditioning?

No. It is a unidirectional non-inverting Schmitt trigger buffer with dedicated input (A) and output (Y) pins. The device does not implement bus-hold, auto-direction sensing, or dual-role I/O functionality. Its architecture is optimized for deterministic edge regeneration from source to load only.

Can 74AXP1G17GXH drive a 50 Ω transmission line directly?

No. With an output drive strength of ±8 mA at VCC = 2.3 V, it cannot sustain 50 Ω termination without excessive VOL/VOH deviation. For controlled-impedance lines, use a dedicated line driver or add series termination; this device is intended for point-to-point CMOS loading within same-board subsystems.

What is the maximum allowable input voltage when VCC = 0 V?

The absolute maximum input voltage is –0.5 V to +3.3 V regardless of VCC state. However, with VCC = 0 V, the IOFF circuit clamps input current to ±0.1 μA max, allowing safe application of up to 2.75 V at pin A without damage or backfeed-critical for hot-plug scenarios.

Is the X2SON5 package lead-free and RoHS compliant?

Yes. The SOT1226-3 package uses lead-free matte tin plating over copper, fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with no exemptions applied. Full material declarations are available in Nexperia's IPC-1752-compliant documentation.
