Product details
Overview
74AUP2G126GF,115 from Nexperia is a dual CMOS buffer/line driver with independent 3-state outputs controlled by active-HIGH output enable inputs (1OE, 2OE). It operates across 0.8 V to 3.6 V supply, delivers propagation delay as low as 1.4 ns at 3.6 V (CL = 5 pF), supports partial power-down via IOFF circuitry, and features Schmitt-trigger inputs for noise immunity in noisy digital interfaces such as I²C bus extensions and sensor signal conditioning.
For engineers reviewing the 74AUP2G126GF,115 datasheet, 74AUP2G126GF,115 pinout, 74AUP2G126GF,115 application, or 74AUP2G126GF,115 equivalent, this device is selected for ultra-low static current (≤1.4 μA max), rail-to-rail input tolerance up to 3.6 V, and guaranteed operation from –40 °C to +125 °C in space-constrained industrial control and battery-powered IoT node designs.
Technical Context
The device implements two independent non-inverting buffers, each with dedicated output enable (nOE) and Schmitt-trigger input (nA), enabling robust signal restoration in slow-rising or noisy environments. Its IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V.
All inputs tolerate voltages up to 3.6 V regardless of VCC level, and the output structure supports high-impedance (Z) states with leakage ≤±0.75 μA over full temperature range. Dynamic performance is characterized across CL = 5–30 pF and VCC = 0.8–3.6 V, with disable time as low as 1.2 ns at 3.6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - enables direct interfacing with 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic domains without level shifters. |
| Max ICC (Static) | 1.4 μA at –40 °C to +125 °C - ensures negligible battery drain in always-on sensor nodes or backup circuits. |
| tpd (nA → nY) | 1.4 ns typical at VCC = 3.6 V, CL = 5 pF - supports >350 MHz data rates in short trace applications like FPGA I/O expansion. |
| IOFF Leakage | ±0.75 μA at VCC = 0 V - prevents cross-talk and damage in hot-swap or multi-rail systems during power sequencing. |
| Input Hysteresis | Typical 120 mV (Schmitt-trigger) - rejects noise spikes up to 120 mV on slow edges, critical for mechanical switch debouncing or long PCB traces. |
| ESD Rating | HBM >5000 V, CDM >1000 V - meets industrial IEC 61000-4-2 immunity requirements without external protection. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives. |
Pinout & Package
XSON8 package (SOT833-1): plastic extremely thin small outline, no leads, 8 terminals, body size 1.0 mm × 1.95 mm × 0.5 mm, thermal padless, pin 1 marked by lower-left corner notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1Y | Output (Buffer 1) | Non-inverting buffered output; driven HIGH/LOW when 1OE = HIGH, high-impedance when 1OE = LOW. |
| 2OE | Output Enable (Buffer 2) | Active-HIGH control: enables/disables 2Y output independently of 1OE and other channels. |
| VCC | Power Supply | Single supply input; powers both buffers and IOFF circuitry; accepts 0.8–3.6 V with full functionality. |
| 2A | Input (Buffer 2) | Data input with Schmitt-trigger action; accepts 0–3.6 V regardless of VCC, enabling mixed-voltage interfacing. |
| 2Y | Output (Buffer 2) | Non-inverting buffered output; identical timing and drive strength to 1Y; fully isolated from 1Y path. |
| 1A | Input (Buffer 1) | Data input with Schmitt-trigger action; immune to slow edges and EMI-induced glitches on PCB traces. |
| 1OE | Output Enable (Buffer 1) | Active-HIGH control: enables/disables 1Y output; allows independent channel gating in multiplexed buses. |
| GND | Ground Reference | 0 V reference for all inputs, outputs, and internal logic; must be low-impedance for stable IOFF operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 1.4 μA over full temperature range - extends battery life in energy-harvesting sensors and wearable devices. |
| IOFF partial power-down | Blocks backflow current when VCC = 0 V - eliminates risk of unintended powering from I/O lines in modular systems. |
| Schmitt-trigger inputs | 120 mV typical hysteresis - eliminates need for external RC filtering in noisy industrial environments or mechanical switch interfaces. |
| Rail-tolerant inputs | VI up to 3.6 V independent of VCC - simplifies interconnection between 1.8 V microcontrollers and 3.3 V peripherals without translators. |
| High noise immunity | CMOS design with >40 % noise margin at VCC = 3.3 V - maintains signal integrity in motor-drive adjacent PCB layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer/line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G126DPWR | Wider VCC range (1.65–5.5 V); higher ICC (10 μA typ); no IOFF; no Schmitt inputs. | Requires external level translation below 1.65 V; unsuitable for true zero-VCC isolation. | Select when interfacing legacy 5 V peripherals and higher drive strength (24 mA) is needed. |
| 74LVC2G126GM,132 | Same XSON8 package; VCC = 1.65–5.5 V; ICC = 10 μA; no IOFF; standard CMOS inputs (no hysteresis). | Lacks Schmitt-trigger noise rejection and IOFF protection - requires external clamping for hot-swap use. | Choose for cost-sensitive consumer applications where 1.65 V minimum supply and no power-down are acceptable. |
Compared with SN74LVC2G126DPWR and 74LVC2G126GM,132, the 74AUP2G126GF,115 uniquely combines sub-μA static current, Schmitt-trigger inputs, and IOFF in a 1.0 mm × 1.95 mm XSON8 package - making it the only option for battery-critical, noise-prone, or multi-rail hot-swap designs.

FAQ
What is the maximum input voltage rating for 74AUP2G126GF,115 when VCC = 1.2 V?
The device supports overvoltage-tolerant inputs up to 3.6 V regardless of VCC level. When VCC = 1.2 V, inputs may safely swing from 0 V to 3.6 V without damage or latch-up, enabling direct connection to 3.3 V sensors or microcontrollers without level-shifting circuitry.
Does 74AUP2G126GF,115 support true bidirectional signal buffering?
No - it is a unidirectional non-inverting buffer with fixed input (nA) and output (nY) paths. Each channel has independent active-HIGH output enable (nOE), but no internal direction control or bus transceiver functionality. Bidirectional operation requires external control logic or a dedicated transceiver IC.
How does the IOFF feature behave during power sequencing in multi-rail systems?
When VCC drops to 0 V, the IOFF circuit automatically places both outputs (1Y, 2Y) in high-impedance state and limits OFF-state leakage to ±0.75 μA. This prevents back-driving from live I/O lines into a powered-down domain, protecting downstream circuitry during asymmetric power-up/down sequences.
Can 74AUP2G126GF,115 drive a 50 pF load while maintaining timing specifications?
No - the datasheet characterizes dynamic performance only up to CL = 30 pF. At 50 pF, propagation delay increases beyond guaranteed limits (e.g., >8.3 ns at VCC = 3.6 V), and output rise/fall times degrade. For >30 pF loads, add series termination or select a higher-drive buffer such as 74AUP2G04.
