Product details

Overview

74AXP1G125 from Nexperia is a single low-power buffer/line driver with 3-state output, Schmitt-trigger inputs for noise immunity, IOFF partial power-down support, and operation across 0.7 V to 2.75 V supply. It delivers ultra-low static current (0.6 μA max at 85 °C), 0.5 pF input capacitance, and propagation delay as low as 1.1 ns at 2.7 V - used in voltage-level translation and bus isolation in portable IoT sensor nodes.

For engineers reviewing the 74AXP1G125 datasheet, 74AXP1G125 pinout, 74AXP1G125 application, or 74AXP1G125 equivalent, key selection criteria include its sub-1V operation capability, IOFF-enabled system power sequencing, Schmitt-trigger hysteresis for slow-edge signal conditioning, and XSON/X2SON footprint compatibility with space-constrained PCB layouts.

Technical Context

This device implements a non-inverting buffer with active-low 3-state enable (OE), where output Y follows input A when OE is LOW and enters high-impedance when OE is HIGH. Its Schmitt-trigger inputs provide hysteresis (typically 0.15 × VCC) to reject noise on slow-rising/falling signals.

The IOFF circuit actively disables both output and input paths when VCC = 0 V, blocking backflow current up to ±20 mA and enabling live insertion into partially powered systems - critical for hot-swap interfaces and multi-rail power domains.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	0.7 V to 2.75 V - supports direct interfacing with 0.8 V, 1.2 V, 1.8 V, and 2.5 V logic domains without level shifters.
IOFF Leakage Current	±0.1 μA max at VCC = 0 V - ensures negligible current path during partial power-down, preventing bus contention.
Propagation Delay (tpd)	1.1 ns typical at VCC = 2.7 V - enables timing-critical signal buffering in high-speed control loops.
Input Capacitance (CI)	0.5 pF typical - minimizes loading on driving circuits, preserving signal integrity in high-frequency routing.
Static Supply Current (ICC)	0.6 μA maximum at 85 °C - extends battery life in always-on sensor interface stages.
Output Drive Strength	±8 mA at VCC = 2.3 V - sufficient to drive 15 pF loads with <3.1 ns max tpd over full temperature range.
Operating Temperature	–40 °C to +85 °C - qualified for industrial-grade embedded control and automotive body electronics.

Pinout & Package

Available in four ultra-thin no-lead packages: SOT886 (XSON6, 1.0 × 1.45 × 0.5 mm), SOT1115 (XSON6, 0.9 × 1.0 × 0.35 mm), SOT1202 (XSON6, 1.0 × 1.0 × 0.35 mm), and SOT1226-3 (X2SON5, 0.8 × 0.8 × 0.32 mm). All variants share identical pin functionality but differ in terminal count and thermal profile.

Pin/Terminal	Circuit Role	Design Meaning
1 (OE)	Output Enable (active-low)	Asserting LOW enables buffer output; HIGH forces Y into high-impedance - used for bus arbitration and power-gated subsystem control.
2 (A)	Data Input	Non-inverting input with Schmitt-trigger threshold - accepts slow edges (up to 200 ns/V transition rate) without oscillation.
3 (GND)	Ground Reference	0 V reference for all I/O and internal logic; must be low-inductance connection to minimize ground bounce.
4 (Y)	Buffered Output	3-state output replicating A when OE = LOW; high-Z when OE = HIGH - isolates downstream loads during standby.
5 (n.c.)	No Connect (SOT886/SOT1115/SOT1202)	Internally unconnected; must remain floating - not usable as thermal pad or auxiliary terminal.
5 (VCC)	Supply Voltage (SOT1226-3)	Power rail input for X2SON5 variant - pin 5 serves as VCC instead of n.c., requiring correct layout mapping per package.
6 (VCC)	Supply Voltage (SOT886/SOT1115/SOT1202)	Single-supply input for all logic and I/O - decoupling capacitor (100 nF) required within 2 mm of this pin.

Key Features

Feature	Design Value
Schmitt-trigger input hysteresis	Enables reliable switching on noisy or slow-rising signals (e.g., mechanical switch debouncing or RC-filtered sensor outputs).
IOFF partial power-down	Prevents damaging back-current flow when VCC = 0 V - essential for PCIe hot-plug, USB-C accessory detection, and modular power architectures.
Sub-1V operation capability	Functional down to 0.7 V supply - supports next-generation ultra-low-power microcontrollers and energy-harvesting systems.
Ultra-low input capacitance	0.5 pF typical - reduces capacitive loading on preceding stage, maintaining signal rise time in high-speed clock distribution paths.
JEDEC-compliant voltage standards	Fully compliant with JESD8-12A.01 through JESD8-5A.01 - guarantees interoperability across 1.1 V to 2.7 V logic families without external biasing.

Applications

Industrial Sensor Interface

Portable Wearable Hub

Use Scenario: Isolating analog-to-digital converter (ADC) digital control lines from noisy motor-driver PCB sections.

IC Role / Device Role / Timing Role: 3-state buffer isolates ADC configuration SPI lines during motor commutation bursts, preventing data corruption.

Use Value: Schmitt-trigger inputs reject EMI-induced glitches on long traces; IOFF prevents backfeed when ADC power rail is cycled independently.

Use Scenario: Level-shifting between a 0.8 V ARM Cortex-M0+ core and 1.8 V display driver IC in a fitness tracker.

IC Role / Device Role / Timing Role: Single-bit buffer translates core GPIO to display enable signal while maintaining sub-microamp quiescent draw.

Use Value: 0.7 V minimum VCC allows direct connection to core's lowest operating voltage; 0.5 pF CI avoids degrading 10 MHz SPI clock edge rates.

Automotive Body Control Module

Smart Home Zigbee Node

Use Scenario: Enabling/disabling LIN bus transceiver control lines during sleep/wake transitions in door module ECUs.

IC Role / Device Role / Timing Role: OE-controlled buffer gates transceiver EN pin, ensuring clean power-up sequencing and zero leakage during deep sleep.

Use Value: IOFF leakage ≤0.1 μA eliminates parasitic drain on 12 V backup battery; –40 °C to +85 °C rating meets automotive ambient requirements.

Use Scenario: Driving reset line of a Zigbee SoC from a 2.5 V MCU GPIO while sharing same 3.3 V power domain.

IC Role / Device Role / Timing Role: Low-capacitance buffer isolates MCU reset assertion from SoC reset pin, reducing cross-talk in RF-sensitive layout.

Use Value: 1.0 pF CO minimizes signal reflection on 20 cm PCB trace; 2.75 V max VI allows safe 3.3 V tolerant operation via clamping diodes.

Equivalent & Alternatives

The following parts are listed as comparable options for similar buffer/line driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC1G125DBVR	Wider VCC range (1.65 V–5.5 V); higher ICC (10 μA typ); no IOFF; no Schmitt input	Requires ≥1.65 V supply; unsuitable for sub-1V or partial power-down use cases	Select only if operating above 1.65 V and IOFF is unnecessary.
74LVC1G125GW,125	Same XSON6 package; identical pinout; IOFF supported; but lacks Schmitt-trigger inputs	Lower noise immunity on slow edges; higher risk of metastability with RC-filtered signals	Choose when Schmitt action is not required and cost optimization is prioritized.

Compared with SN74LVC1G125DBVR and 74LVC1G125GW,125, the 74AXP1G125 uniquely combines sub-1V operation, IOFF, and Schmitt-trigger inputs - making it the sole option for battery-powered systems requiring robust signal conditioning and multi-rail power sequencing.

FAQ

What is the minimum supply voltage at which 74AXP1G125 guarantees functional operation?

The device is fully specified from 0.7 V to 2.75 V per JEDEC standards. At 0.7 V, propagation delay is 38 ns (max) and output drive is reduced, but logic functionality, IOFF behavior, and Schmitt-trigger thresholds remain guaranteed across –40 °C to +85 °C. Below 0.7 V, operation is not characterized.

Can 74AXP1G125 safely interface between a 3.3 V microcontroller and a 1.8 V peripheral?

No - the absolute maximum input voltage is +3.3 V, but the recommended VI range is 0 V to 2.75 V. Applying 3.3 V to A or OE exceeds specification and risks damage. For 3.3 V → 1.8 V translation, use a dedicated level shifter or add external clamping diodes with current limiting.

Does the 'n.c.' pin on SOT886/SOT1115/SOT1202 packages require PCB connection?

No - pin 5 is internally unconnected and must remain floating. It is not a thermal pad or ground tie. Connecting it may cause unpredictable behavior or violate package thermal derating curves. Layout guidelines explicitly prohibit soldering or routing to this terminal.

How does the IOFF feature behave when VCC is ramping during power-up?

IOFF activates automatically when VCC drops below ~0.2 V and remains active until VCC rises above ~0.4 V. During this window, both input and output terminals are high-impedance regardless of OE state - preventing back-current flow even during asymmetric power sequencing where other rails are already active.
