Product details
Overview
74AUP2G34DW-7 from Diodes Incorporated is a dual non-inverting buffer IC in the Advanced Ultra Low Power (AUP) CMOS logic family, designed for level-shifting and signal conditioning in battery-powered systems. It operates from 0.8V to 3.6V, 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 portable electronics.
For engineers reviewing the 74AUP2G34DW-7 datasheet, 74AUP2G34DW-7 pinout, 74AUP2G34DW-7 application, or 74AUP2G34DW-7 equivalent, this device is selected for ultra-low static current (<0.9µA ICC), fast propagation delay (as low as 1.4ns at 3.3V/CL=5pF), and robust ESD tolerance (2kV HBM), especially where supply voltage scalability and power-gating compatibility are critical.
Technical Context
This dual buffer implements two independent positive-logic functions (Y = A) with standard push-pull outputs and no internal inversion. Its IOFF circuit actively disables outputs during power-down to prevent back-current flow between powered and unpowered rails - essential for mixed-voltage domain interconnects.
Schmitt-trigger inputs provide hysteresis (~250mV at 3.0V), enabling reliable operation with slow-rising or noisy signals without external RC filtering. The device is fully characterized across –40°C to +125°C and supports dynamic loading up to 30pF with sub-5ns typical propagation delay at 3.3V.
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 at +25°C - minimizes quiescent drain in always-on subsystems like real-time clocks or wake-up monitors. |
| Output Drive Strength | ±4mA at VCC = 3.0V - sufficient to drive multiple CMOS loads or short PCB traces without buffering. |
| Propagation Delay (tpd) | 1.4ns typical at VCC = 3.3V, CL = 5pF - supports >300MHz signal integrity in high-speed control paths. |
| Input Hysteresis | ~250mV at VCC = 3.0V - rejects noise on slow-switching lines such as mechanical switch debouncing or sensor outputs. |
| IOFF Leakage | ±0.2µA max at 0V - ensures safe isolation when one side of a bus is powered down while the other remains active. |
| ESD Protection | 2kV HBM, 1kV CDM - exceeds JEDEC JESD22-A114/A101 requirements for handheld and portable assembly environments. |
Pinout & Package
SOT363 (2.0mm × 2.0mm × 1.1mm, 0.65mm lead pitch) surface-mount package with exposed pad not electrically connected. Six-pin layout optimized for compact routing and thermal dissipation in space-constrained PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A | Data Input Channel 1 | Non-inverting input for first buffer; accepts 0.8–3.6V logic levels with Schmitt-trigger threshold. |
| GND (Pin 2) | Ground Reference | Primary return path for both buffers and internal bias networks; must be low-impedance for noise immunity. |
| 2A | Data Input Channel 2 | Independent non-inverting input for second buffer; electrically isolated from 1A except via shared VCC/GND. |
| 2Y | Data Output Channel 2 | Push-pull output sourcing/sinking up to ±4mA; IOFF active when VCC = 0V to block backfeed. |
| VCC (Pin 5) | Power Supply | Single-supply rail powering both buffers; supports brown-out tolerant operation down to 0.8V. |
| 1Y | Data Output Channel 1 | Matched-output driver with identical timing and drive specs as 2Y; enables dual-signal fanout. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ICC | 0.5–0.9µA over full voltage range - extends battery life in IoT sensors and wearables operating for years on coin cells. |
| IOFF Partial-Power-Down | Active output disable below VCC = 0.2V - prevents cross-talk and latch-up in hot-plug or multi-rail power sequencing. |
| Schmitt-Trigger Inputs | 250mV hysteresis at 3.0V - eliminates need for external RC filters on noisy GPIO lines or mechanical switch interfaces. |
| Wide-Voltage Operation | 0.8–3.6V supply range - allows direct connection to Li-ion battery (2.7–4.2V), LDO outputs (1.2/1.8/2.5/3.3V), or energy-harvesting sources. |
| Lead-Free & Green | Halogen- and antimony-free, RoHS-compliant construction - meets IPC-1752A material declaration and automotive PPAP requirements. |
Applications
| Portable Power Management | Low-Power Sensor Interface |

Use Value: Reduces required base drive current by 60% compared to discrete transistor solutions, improving thermal margin and long-term reliability under continuous 24/7 operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G34DBVR | Wider VCC range (1.65–5.5V); higher ICC (10µA typ); no Schmitt inputs; IOFF not supported. | Better suited for 5V legacy systems; unsuitable for sub-1.2V operation or partial-power-down architectures. | Select only if interfacing with 5V peripherals and power sequencing is not required. |
| 74AHC2G34GW,125 | Higher speed (tpd = 2.3ns @ 3.3V); higher drive (±8mA); no IOFF; 2.0–5.5V supply; higher ICC (40µA). | Optimized for speed-critical control paths (e.g., FPGA configuration buses); lacks battery-life optimization. | Choose when propagation delay dominates over static power - e.g., clock distribution or high-frequency data strobes. |
Compared with SN74LVC2G34DBVR and 74AHC2G34GW,125, the 74AUP2G34DW-7 uniquely balances ultra-low ICC, IOFF-enabled power gating, and Schmitt-trigger noise immunity - making it the only option among the three viable for always-on, multi-rail, battery-operated endpoints.

FAQ
What is the minimum operating voltage for reliable logic-level translation?
The 74AUP2G34DW-7 is fully specified from 0.8V to 3.6V. At 0.8V, it maintains valid VIH/VIL thresholds (VIH = 0.8×VCC = 0.64V, VIL = 0.3×VCC = 0.24V) and delivers ≥20µA output drive - enabling direct interface with sub-1V processors and energy-harvesting SoCs without level-shifting overhead.
Does the device support hot insertion or live board swapping?
Yes - the IOFF feature actively disables outputs when VCC drops below ~0.2V, preventing damaging back-current flow into powered downstream circuits. This makes the 74AUP2G34DW-7 suitable for hot-plug modules, modular sensor nodes, and field-replaceable units where power sequencing cannot be guaranteed.
Can Schmitt-trigger inputs be bypassed for standard CMOS behavior?
No - Schmitt-trigger action is inherent to the input structure and cannot be disabled. However, its 250mV hysteresis at 3.0V improves noise margin without degrading speed; for pure CMOS thresholds, select the non-Schmitt 74AUP2G125 variant instead.
Is the SOT363 package compatible with standard reflow profiles?
Yes - the SOT363 package meets JEDEC J-STD-020D moisture sensitivity level 1 (MSL-1) and is qualified for peak reflow temperatures up to 260°C. Its 0.65mm pitch and 2.0×2.0mm footprint align with standard 0402-class placement equipment and IPC-7351B land patterns.
