Product details

Overview

74AUP1G125GX,125 from Nexperia is a single low-power 3-state buffer/line driver with Schmitt-trigger inputs, operating across 0.8 V to 3.6 V supply range. It delivers ultra-low static current (≤1.4 μA at −40 °C to +125 °C), IOFF-enabled partial power-down protection, and 5-pin X2SON5 (SOT1226-3) packaging for space-constrained IoT sensor interfaces and battery-powered wearables.

For engineers reviewing the 74AUP1G125GX,125 datasheet, 74AUP1G125GX,125 pinout, 74AUP1G125GX,125 application, or 74AUP1G125GX,125 equivalent, key selection criteria include its 0.8 V minimum VCC support, <0.5 μA ICC at 25 °C, IOFF leakage ≤±0.75 μA during power-down, and guaranteed operation up to +125 °C in thermally demanding embedded control nodes.

Technical Context

This device implements a non-inverting buffer with active-low 3-state output enable (OE), where Schmitt-trigger input thresholds provide noise immunity against slow-rising signals in noisy industrial bus environments. The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current from live buses into unpowered subsystems.

Its dynamic performance is characterized by propagation delay as low as 1.4 ns (VCC = 3.0–3.6 V, CL = 5 pF), with enable/disable times under 4 ns - enabling reliable signal conditioning in high-speed serial data paths while maintaining sub-100 nW dynamic power at 1 MHz switching.

Key Specifications

Parameter Value and Actual Design Meaning
VCC Range 0.8 V to 3.6 V - supports direct interface with 0.9 V logic families and legacy 3.3 V systems without level shifters.
ICC (max) 1.4 μA at −40 °C to +125 °C - enables multi-year battery life in always-on sensor nodes.
IOFF Leakage ±0.75 μA at VCC = 0 V - prevents damaging back-current in hot-swap or partial-power-down architectures.
tpd (min) 1.4 ns at VCC = 3.3 V, CL = 5 pF - ensures timing-critical signal buffering in high-frequency clock distribution paths.
VIH/VIL VIL ≤ 0.3×VCC, VIH ≥ 0.7×VCC (at VCC = 1.4 V) - provides robust noise margin >300 mV in electrically noisy automotive body-control modules.
Operating Temp −40 °C to +125 °C - qualified for under-hood automotive ECUs and industrial motor drive control boards.
ESD Rating HBM >5000 V, CDM >1000 V - withstands handling and board assembly without special ESD precautions.

Pinout & Package

X2SON5 package (SOT1226-3): plastic thermal-enhanced extremely thin small outline, no leads, 5 terminals, body size 0.8 mm × 0.8 mm × 0.32 mm, thermal pad on bottom, side-wettable flanks not present.

Pin/Terminal Circuit Role Design Meaning
1 (OE) Output Enable (active-low) Drives Y to high-impedance when logic HIGH; enables bus sharing in multi-driver systems.
2 (A) Data Input Schmitt-trigger input accepts slow edges (Δt/ΔV ≤ 200 ns/V) without oscillation in noisy environments.
3 (GND) Ground Reference 0 V reference for all I/O and internal logic; must be low-inductance connection for stable 3-state transitions.
4 (Y) Buffered Output Non-inverting output with 3-state capability; drives capacitive loads up to 30 pF with <5 ns delay variation.
5 (VCC) Supply Voltage Power rail for core logic and output drivers; supports wide-range operation from 0.8 V (ultra-low-power mode) to 3.6 V.

Key Features

Feature Design Value
Wide VCC range 0.8 V to 3.6 V enables single-bom compatibility across 0.9 V, 1.2 V, 1.8 V, 2.5 V, and 3.3 V system domains.
IOFF partial power-down Prevents destructive back-current flow when VCC = 0 V but A or Y remain biased - critical for modular hot-plug designs.
Schmitt-trigger inputs Input hysteresis ≥150 mV at VCC = 1.2 V eliminates false triggering from EMI-induced ringing on long PCB traces.
Ultra-low ICC ≤0.9 μA max at 25 °C allows integration into always-on wake-up circuits without measurable battery drain.
Thermal-enhanced X2SON5 0.32 mm height and exposed die pad improve thermal resistance (RθJA ≈ 220 K/W) for sustained operation in sealed enclosures.

Equivalent & Alternatives

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

Alternative Part Technical Difference Application Difference Selection Advice
74LVC1G125GW,125 Higher ICC (max 10 μA), narrower VCC range (1.65 V–5.5 V), no IOFF, TSSOP5 package (larger footprint) Not suitable for sub-1.65 V systems or partial power-down designs; requires external pull-down on OE for default disable Select only if operating above 1.65 V and cost is primary constraint; avoid for battery-powered or hot-swap systems.
SN74AUP1G125DBVR Texas Instruments variant; identical electrical specs but different package (SOT-23-5), slightly higher tpd (1.8 ns typical at 3.3 V) Same functional behavior but incompatible pinout (OE on pin 1 vs. pin 1 on GX); requires PCB redesign Use only for TI-design ecosystems; verify layout compatibility - pin 1 location differs despite identical logic function.

Compared with 74LVC1G125GW,125 and SN74AUP1G125DBVR, the 74AUP1G125GX,125 uniquely combines ultra-low-voltage operation (0.8 V), guaranteed IOFF, and the smallest industry-standard footprint (X2SON5), making it optimal for next-gen ultra-compact, energy-harvesting, and automotive-grade designs.

FAQ

What is the maximum load capacitance supported by the 74AUP1G125GX,125 without violating timing specifications?

The device is fully characterized up to 30 pF load capacitance across all VCC and temperature ranges. At VCC = 3.3 V and Tamb = 25 °C, propagation delay remains ≤5.8 ns with CL = 30 pF, and output rise/fall times stay within 1.5 ns. Exceeding 30 pF may increase delay unpredictably and degrade noise margins due to increased capacitive loading on the output driver stage.

Can the 74AUP1G125GX,125 safely interface with 5 V logic signals?

No - absolute maximum input voltage is +4.6 V, but the device is not 5 V tolerant. Inputs must remain ≤3.6 V per specification. Direct connection to 5 V buses risks latch-up or accelerated degradation. Use a resistive divider or dedicated level translator (e.g., TXB0104) when interfacing with 5 V systems.

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

IOFF activates only when VCC falls to 0 V; during power-up, the device operates normally once VCC exceeds ~0.4 V. No special sequencing is required - OE can be asserted before VCC stabilizes, and the output remains high-impedance until VCC reaches valid logic thresholds (~0.7×VCC). This avoids bus contention during cold-start sequences.

Is the X2SON5 (SOT1226-3) package compatible with standard reflow profiles for lead-free assembly?

Yes - the package is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL-1) and supports peak reflow temperatures up to 260 °C. Its thermal-enhanced construction allows full compliance with standard Pb-free reflow profiles (e.g., JEDEC Level 3), including preheat, soak, and ramp-to-peak phases, without delamination or solder voiding.
