Product details
Overview
74AUP2G34FW3-7 from Diodes Incorporated is a dual non-inverting buffer IC in the Advanced Ultra Low Power (AUP) CMOS logic family, designed for signal buffering in battery-powered portable systems. 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-immune interfacing in handheld electronics.
For engineers reviewing the 74AUP2G34FW3-7 datasheet, 74AUP2G34FW3-7 pinout, 74AUP2G34FW3-7 application, or 74AUP2G34FW3-7 equivalent, this device is selected for ultra-low static current (<0.9µA), fast propagation delay (as low as 1.4ns at 3.3V/CL=5pF), and compact X2-DFN0910-6 packaging in space-constrained, energy-sensitive designs.
Technical Context
This dual buffer implements two independent positive-logic non-inverting functions (A → Y) with standard push-pull outputs. Its IOFF circuit actively disables outputs during power-down to prevent backflow current, enabling safe hot-insertion and multi-rail system interoperability.
Schmitt-trigger inputs provide robust noise immunity with 250mV typical hysteresis at 3.0V, supporting slow-rising/falling signals without oscillation. The device is fully characterized from –40°C to +125°C and supports 0.8V minimum VCC for compatibility with emerging ultra-low-voltage microcontrollers and sensors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8V to 3.6V - Enables direct interface with 0.9V/1.2V/1.8V/2.5V/3.3V logic domains and battery voltage decay down to 0.8V. |
| Static Supply Current (ICC) | <0.9µA at +25°C - Minimizes quiescent drain in always-on sensor nodes and sleep-mode peripherals. |
| Output Drive Strength | ±4mA at VCC = 3.0V - Sufficient to drive 50Ω transmission lines or fan-out to ≥10 standard AUP loads. |
| Propagation Delay (tpd) | 1.4ns typical at VCC = 3.3V, CL = 5pF - Supports >300MHz signal routing in high-speed control paths. |
| Input Hysteresis | 250mV typical at VCC = 3.0V - Rejects up to ±125mV of input noise without false triggering on noisy PCB traces. |
| IOFF Leakage | ±0.2µA max at 0V - Ensures <100nW power loss when powered down while inputs remain active. |
| ESD Protection | 2kV HBM, 1kV CDM, 200V MM - Meets IEC 61000-4-2 Level 2 for handheld device front-end robustness. |
Pinout & Package
X2-DFN0910-6 is a 0.9mm × 1.0mm × 0.35mm leadless package with 0.35mm pad pitch and exposed thermal pad (not electrically connected). It complies with JESD30E and supports reflow soldering per IPC/JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Data Input Channel 1 | Non-inverting input accepting 0.8V–3.6V logic levels; Schmitt-triggered for noise margin. |
| GND | Ground Reference | Primary return path for all internal logic and output currents; connects to PCB ground plane. |
| 2A | Data Input Channel 2 | Independent non-inverting input with identical Schmitt characteristics to Pin 1A. |
| 2Y | Data Output Channel 2 | Push-pull output sourcing/sinking up to ±4mA; disabled by IOFF when VCC = 0V. |
| VCC | Power Supply | Single-supply rail powering both buffers; IOFF remains functional even if VCC floats below 0.5V. |
| 1Y | Data Output Channel 1 | Electrically isolated from 2Y; supports independent loading and timing in split-bus architectures. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ICC | 0.5µA typical at +25°C - Extends coin-cell life beyond 10 years in IoT wake-up circuits. |
| IOFF Partial Power-Down | Active at VCC = 0V - Allows live insertion into powered-backplane systems without bus contention. |
| Schmitt-Trigger Inputs | 250mV hysteresis at 3.0V - Eliminates need for external RC filtering on long flex-cable interconnects. |
| Wide VCC Range | 0.8V–3.6V operation - Matches output swing of modern sub-1V MCUs and 3.3V peripherals in mixed-voltage SoC interfaces. |
| Lead-Free & Green | Halogen-free, antimony-free, RoHS-compliant - Meets EU Directive 2011/65/EU and automotive AEC-Q200 material requirements. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G34DBVR | Higher ICC (1µA typ), no Schmitt inputs, 1.65V–5.5V VCC range | Lacks hysteresis; unsuitable for noisy industrial sensor lines or slow-rising battery monitor signals | Select when interfacing only clean CMOS outputs and requiring 5V tolerance. |
| 74AHC1G125W5-7 | Single-channel, higher drive (±8mA), no IOFF, 2.0V–5.5V VCC | Requires two devices for dual function; no power-down isolation for hot-swap use cases | Choose for cost-sensitive single-buffer needs where IOFF is not required. |
Compared with SN74LVC2G34DBVR and 74AHC1G125W5-7, the 74AUP2G34FW3-7 uniquely combines ultra-low ICC, Schmitt inputs, and IOFF in a single dual-channel DFN0910 package-making it optimal for battery-constrained, noise-prone, and hot-pluggable embedded interfaces.

FAQ
What is the maximum capacitive load the 74AUP2G34FW3-7 can drive while maintaining specified tpd?
The datasheet specifies switching characteristics up to CL = 30pF, with tpd = 2.2ns (typ) at VCC = 3.3V. Driving >30pF increases delay nonlinearly and may exceed the 4.2ns max limit at 125°C. For loads >30pF, add series termination or reduce trace length to maintain signal integrity within timing budget.
Can 74AUP2G34FW3-7 be used with 0.8V logic inputs while powered at 3.3V?
Yes. VIH(min) at VCC = 3.3V is 2.0V, but the device accepts VI down to 0V regardless of VCC. A 0.8V input falls below VIH threshold and registers as logic LOW, consistent with its Boolean function. This enables reliable reset signaling from low-voltage supervisors.
Does the X2-DFN0910-6 package require thermal vias under the exposed pad?
No. The X2-DFN0910-6 has no thermal pad - its bottom surface is dielectric. Thermal dissipation occurs via copper traces connected to Pins 2 (GND) and 5 (VCC). Follow Diodes' AP02001 recommended pad layout with 0.35mm pitch and 0.15mm solder mask opening.
How does IOFF behave when VCC is ramping during power-up?
IOFF activates when VCC drops below ~0.3V and remains active until VCC exceeds ~0.5V. During ramp-up, outputs stay high-impedance until VCC crosses the turn-on threshold, preventing glitch-induced bus contention. This behavior is verified across –40°C to +125°C per DS35514 Rev. 6–2.
