Product details
Overview
74AUP2G34FW4-7 from Diodes Incorporated is a dual non-inverting buffer IC in the Advanced Ultra Low Power (AUP) CMOS logic family, designed for signal conditioning and level translation in battery-powered portable electronics. It operates across 0.8V–3.6V supply, delivers ±4mA output drive at 3.0V, features IOFF partial power-down protection, and uses Schmitt-trigger inputs with ~250mV hysteresis at VCC = 3.0V for noise immunity in low-slew-rate interfaces.
For engineers reviewing the 74AUP2G34FW4-7 datasheet, 74AUP2G34FW4-7 pinout, 74AUP2G34FW4-7 application, or 74AUP2G34FW4-7 equivalent, this device is selected for ultra-low static current (<0.9µA ICC), fast propagation delay (as low as 1.4ns typ at 3.3V/CL=5pF), and robust ESD tolerance (2kV HBM), especially where supply voltage scalability and I/O isolation during power sequencing are critical.
Technical Context
This dual buffer implements two independent positive-logic A → Y functions with standard push-pull outputs and no internal inversion. Its IOFF circuit actively disables outputs when VCC = 0V, preventing back-current flow into powered subsystems - essential for hot-plug and multi-rail partial-power-down architectures.
Schmitt-trigger inputs provide defined switching thresholds (VIH/VIL ratios vary by VCC range: e.g., 0.80×VCC min VIH at 0.8–1.65V), enabling reliable operation with slow-rising signals common in sensor interfaces or legacy bus stubs. The device supports full rail-to-rail input and output swing under all valid supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8V to 3.6V - enables direct interface with 1.2V, 1.8V, 2.5V, and 3.3V logic domains without level shifters. |
| Static Supply Current (ICC) | <0.9µA max at +25°C - extends battery life in always-on sensor nodes and standby circuits. |
| Output Drive Strength | ±4mA at VCC = 3.0V - sufficient to drive 50Ω transmission lines or multiple CMOS inputs (fan-out ≥10 @ 3.3V). |
| Propagation Delay (tpd) | 1.4ns typical at VCC = 3.3V, CL = 5pF - supports >300MHz data rates in short-reach digital interconnects. |
| Input Hysteresis | ~250mV at VCC = 3.0V - rejects noise up to ±125mV on slow edges (e.g., from RC-filtered microcontroller GPIOs). |
| IOFF Leakage | ±0.6µA max at VCC = 0V - ensures safe isolation between unpowered and active voltage domains during system sleep. |
| ESD Protection | 2kV HBM, 1kV CDM - meets industrial IEC 61000-4-2 Level 2 requirements without external protection diodes. |
Pinout & Package
X2-DFN1010-6 package: 1.0mm × 1.0mm × 0.4mm body, 0.35mm pad pitch, leadless, RoHS-compliant, thermal pad optional.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Input A of Buffer 1 | Primary logic input for first buffer; accepts 0.8V–3.6V CMOS-compatible signals with Schmitt-trigger threshold. |
| GND | Ground Reference | Common return path for both buffers and internal logic; must be low-impedance for stable noise margin. |
| 2A | Input A of Buffer 2 | Independent logic input for second buffer; electrically isolated from 1A but shares same VCC/GND rails. |
| 2Y | Output Y of Buffer 2 | Push-pull output sourcing/sinking up to ±4mA; driven high/low per input state with no pull-up required. |
| VCC | Power Supply | Single-supply rail powering both buffers; IOFF activates automatically when VCC = 0V. |
| 1Y | Output Y of Buffer 1 | Matched-output drive capability and timing to 2Y; supports parallel buffering or signal fan-out. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC < 0.9µA ensures negligible quiescent drain in battery-backed real-time clocks or memory retention circuits. |
| IOFF partial power-down | Active output disable at VCC = 0V prevents backfeeding into powered buses - critical for PCIe slot hot-plug and USB-C port controllers. |
| Schmitt-trigger inputs | 250mV hysteresis at 3.0V eliminates chatter on noisy or slow-rising signals from mechanical switches or analog comparators. |
| Wide VCC scalability | 0.8V–3.6V operation allows direct use with modern sub-1V SoC I/Os and legacy 3.3V peripherals without voltage translation. |
| Leadless DFN packaging | X2-DFN1010-6 footprint saves >60% board area vs. SOT363 while maintaining thermal performance via exposed pad option. |
Applications
| Mobile Device Power Sequencing | Low-Power Sensor Interface |

Use Scenario: Isolating enable signals between a PMIC's 1.2V domain and an MCU's 3.3V I/O bank during deep-sleep wake-up sequences. IC Role / Device Role / Timing Role: Dual buffer provides level-shifted, glitch-free enable propagation with IOFF ensuring no leakage when PMIC is off. Use Value: Eliminates need for discrete MOSFET level shifters and reduces BOM count by 2 components per signal path. |
Use Scenario: Conditioning output from a thermistor-based analog comparator with 10ms rise time before feeding to an ADC trigger input. IC Role / Device Role / Timing Role: Schmitt-trigger input cleans slow, noisy comparator edge; push-pull output drives ADC's digital input with fast, rail-to-rail swing. Use Value: Prevents false triggers caused by noise-induced oscillation at comparator threshold, improving measurement reliability. |
| Wearable Display Backlight Control | IoT Edge Node GPIO Expansion |
|
Use Scenario: Driving PWM-controlled LED backlight in a smartwatch where main SoC operates at 0.8V but display driver requires 1.8V logic levels. IC Role / Device Role / Timing Role: Buffer translates 0.8V PWM signal to full 1.8V swing while maintaining <2ns jitter for flicker-free dimming. Use Value: Enables direct SoC-to-display connection without dedicated level shifter IC, reducing power and latency. |
Use Scenario: Expanding limited GPIO count on a BLE SoC to control four external sensors, each requiring clean, isolated enable signals. IC Role / Device Role / Timing Role: Two independent buffers provide synchronized, low-skew enable pulses with matched propagation delay (Δtpd < 0.3ns). Use Value: Ensures simultaneous sensor activation for coherent multi-sensor sampling, avoiding timestamp skew in fusion algorithms. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G34DBVR | Higher ICC (10µA typ), narrower VCC range (1.65–5.5V), no Schmitt inputs, no IOFF. | Requires external pull-ups for open-drain compatibility; unsuitable for partial-power-down systems. | Select only if operating exclusively above 1.65V and ESD/leakage specs are secondary. |
| 74AHC2G34GW,125 | Higher drive (±8mA), faster tpd (1.1ns typ), but ICC = 2µA and no IOFF or Schmitt inputs. | Better for speed-critical paths but lacks noise immunity and power-domain isolation features. | Prefer when maximum throughput is prioritized over battery life and mixed-voltage robustness. |
Compared with SN74LVC2G34DBVR and 74AHC2G34GW,125, the 74AUP2G34FW4-7 uniquely combines ultra-low ICC, IOFF, Schmitt inputs, and sub-1V operation - making it the sole choice for energy-constrained, multi-rail, noise-prone portable designs.

FAQ
What is the minimum supply voltage for guaranteed operation of the 74AUP2G34FW4-7?
The device is fully specified down to 0.8V VCC, with validated performance including VIH/VIL thresholds, output drive, and propagation delay across the entire –40°C to +125°C temperature range. Below 0.8V, functionality is not guaranteed per datasheet limits.
Does the 74AUP2G34FW4-7 require external pull-up or pull-down resistors on its inputs?
No. Inputs feature Schmitt-trigger action with defined hysteresis, eliminating need for external biasing. Unused inputs should be tied to VCC or GND per recommended operating conditions to prevent floating states and excess current draw.
Can the 74AUP2G34FW4-7 safely interface between a 1.2V domain and a 3.3V domain?
Yes - its 0.8V–3.6V VCC range and rail-to-rail input thresholds allow direct connection to both domains. However, output swing follows VCC, so level translation requires either VCC = 3.3V (to drive 3.3V loads) or external circuitry for bidirectional translation.
Is the X2-DFN1010-6 package thermally enhanced?
The package has no integral thermal pad, but its 1.0mm × 1.0mm footprint and copper-exposed side walls enable effective heat dissipation through PCB copper pour. Thermal resistance θJA is 210°C/W (typ) with 25mm² 1-oz copper, sufficient for ≤1mW total power dissipation.
