Product details
Overview
74AUP1G126GW,125 from Nexperia is a single non-inverting 3-state buffer/line driver in TSSOP5 (SOT353-1) package, operating from 0.8 V to 3.6 V supply. It features Schmitt-trigger inputs for noise immunity, input-disable functionality during OE low, and IOFF circuitry enabling partial power-down with <±0.75 μA off-state leakage. Used in voltage-level translation and bus isolation in ultra-low-power IoT sensor nodes.
For engineers reviewing the 74AUP1G126GW,125 datasheet, 74AUP1G126GW,125 pinout, 74AUP1G126GW,125 application, or 74AUP1G126GW,125 equivalent, key selection criteria include its 0.9 μA max ICC at 3.6 V, 1.4 ns min propagation delay at 3.3 V/CL=5 pF, -40 °C to +125 °C rating, and TSSOP5 thermal profile for space-constrained PCBs.
Technical Context
This device implements a single-channel non-inverting logic buffer with active-high output enable (OE), where OE LOW forces Y into high-impedance state and disables A input. Schmitt-trigger inputs ensure robust operation across full VCC range (0.8–3.6 V) with hysteresis ≥0.1 V typical, tolerating slow edges up to 200 ns/V.
The IOFF protection circuit actively blocks backflow current when VCC = 0 V, limiting IOFF to ±0.75 μA - critical for hot-swap and multi-rail systems. Input voltage tolerance extends to 3.6 V regardless of VCC, enabling mixed-voltage interfacing without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 0.8 V to 3.6 V - supports direct interface with 0.9 V, 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains |
| Max ICC | 0.9 μA at VCC = 3.6 V - enables >10-year battery life in always-on sensor wake-up circuits |
| tpd (A→Y) | 1.4 ns min at VCC = 3.0 V, CL = 5 pF - meets timing closure for sub-500 MHz digital control loops |
| VIH / VIL | VIL ≤ 0.25×VCC, VIH ≥ 0.70×VCC at VCC = 0.8 V - ensures reliable switching with degraded signal integrity |
| IOFF Leakage | ±0.75 μA at VCC = 0 V - prevents cross-rail current in powered-down subsystems |
| Operating Temp | -40 °C to +125 °C - qualified for under-hood automotive and industrial motor drive control |
| ESD Rating | HBM >5000 V, CDM >1000 V - withstands handling and board assembly without additional protection |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, 0.65 mm pitch, 0.8 mm height - optimized for automated placement and thermal dissipation in dense layouts.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OE (Output Enable) | Active-HIGH control: HIGH enables non-inverting buffer; LOW disables output and input (floating-tolerant) |
| 2 | A (Data Input) | Schmitt-trigger input accepting 0–3.6 V; disabled when OE = LOW to prevent floating-induced current |
| 3 | GND | Reference ground terminal - must be low-inductance connection to minimize switching noise coupling |
| 4 | Y (Data Output) | 3-state non-inverting output; high-impedance when OE = LOW; drives up to ±4 mA at VCC = 3.0 V |
| 5 | VCC | Power supply input - decoupling capacitor (100 nF) required within 2 mm for stable high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC Range | 0.8 V to 3.6 V enables single-bom deployment across 0.9 V microcontrollers, 1.8 V FPGAs, and 3.3 V peripherals |
| Input-Disable Logic | Automatic A-input disable when OE = LOW eliminates static current from floating inputs in standby mode |
| IOFF Protection | Prevents damaging backflow current during partial power-down - essential for PCIe hot-plug and modular power systems |
| Schmitt-Trigger Inputs | ≥0.1 V hysteresis rejects noise on slow-rising signals (e.g., mechanical switch debouncing, long trace interfaces) |
| Low Dynamic Power | CPD = 4.2 pF at VCC = 3.3 V - reduces dynamic power by >60% vs. standard AUP series at same frequency |
Applications
| Industrial Sensor Interface | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G126DBVR | Wider VCC (1.65–5.5 V); higher ICC (10 μA typ); no input-disable feature | Lacks IOFF and input-disable - unsuitable for partial power-down systems | Select only if 5 V compatibility is mandatory and system lacks hot-swap requirements |
| 74LVC1G125GW,125 | Inverting function; identical package, VCC range, and timing specs | Requires logic inversion in signal path - adds design complexity for non-inverting use cases | Choose only when inverting behavior aligns with existing schematic topology |

FAQ
What is the maximum capacitive load the 74AUP1G126GW,125 can drive while maintaining specified tpd?
The device is characterized up to 30 pF load capacitance. At VCC = 3.3 V and CL = 30 pF, tpd is 4.6 ns (typical) and 5.8 ns (max) over -40 °C to +125 °C - verified per JEDEC JESD78 latch-up and JESD22-A114 HBM test standards. Exceeding 30 pF increases propagation delay nonlinearly and may violate setup/hold margins in synchronous systems.
Does the input-disable feature affect timing parameters like tpd or ten?
No - input-disable only gates internal input stage current when OE = LOW; it does not alter propagation or enable/disable timing. All dynamic specifications (tpd, ten, tdis) are measured with OE = HIGH and A switching. The feature solely reduces ICC by eliminating input leakage paths during standby.
Can 74AUP1G126GW,125 be used with VCC = 0.8 V and still meet VIH/VIL thresholds?
Yes - at VCC = 0.8 V, VIH is guaranteed ≥0.70 × VCC = 0.56 V and VIL ≤0.25 × VCC = 0.20 V. This provides 360 mV noise margin for 0.8 V logic systems, validated across -40 °C to +125 °C with Schmitt-trigger hysteresis ensuring monotonic transitions.
Is there a recommended PCB layout practice for minimizing ground bounce in high-frequency switching?
Place a 100 nF X7R ceramic decoupling capacitor between pins 3 (GND) and 5 (VCC), with trace length <2 mm and direct connection to solid ground plane. Avoid routing A or Y traces parallel to VCC/GND; maintain ≥3× trace width spacing to reduce crosstalk. Thermal pad (if present in variant) must be tied to GND with ≥4 thermal vias.
