Product details
Overview
74AUP1G34FW5-7 from Diodes Incorporated is a single-channel CMOS buffer gate with push-pull output, designed for ultra-low-power signal conditioning in battery-powered portable electronics. It operates across 0.8V–3.6V supply, delivers ±4mA drive at 3.0V, features IOFF partial power-down protection, and includes Schmitt-trigger inputs (250mV hysteresis at 3.0V) for noise immunity in noisy or slow-rising environments-used in smartphone baseband signal routing and e-reader display interface buffering.
For engineers reviewing the 74AUP1G34FW5-7 datasheet, 74AUP1G34FW5-7 pinout, 74AUP1G34FW5-7 application, or 74AUP1G34FW5-7 equivalent, key selection criteria include its 0.8V minimum VCC compatibility, sub-1µA ICC static current, IOFF-enabled system-level power sequencing, and DFN1010-6 footprint suitability for space-constrained PCB layouts.
Technical Context
This device implements a non-inverting logic function (Y = A) using advanced ultra-low-power (AUP) CMOS process technology optimized for sub-1V operation. Its Schmitt-trigger input stage provides defined switching thresholds and hysteresis (250mV typ. at VCC = 3.0V), enabling robust interfacing with slow or degraded signals without external RC filtering.
The IOFF circuit actively disables output leakage during partial power-down states, preventing back-current flow when VCC = 0V while inputs remain biased-critical for multi-rail systems like USB-C PD controllers or PMIC sequenced subsystems where rail independence is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8V to 3.6V - supports direct connection to Li-ion battery voltage (2.7–4.2V) via LDO or direct to 1.2V/1.8V/3.3V rails without level shifting |
| Output Drive Strength | ±4mA at 3.0V - sufficient to drive 50Ω transmission lines or fan-out to ≥10 standard CMOS loads at 3.3V |
| Static Supply Current | <0.9µA max - enables multi-year battery life in always-on sensor nodes or RTC backup paths |
| IOFF Leakage | <0.6µA at 3.6V - ensures <10nW standby power dissipation during system sleep modes |
| Propagation Delay | 1.0ns min / 3.2ns typ at 3.3V, CL=5pF - meets timing closure for 200+ MHz clock distribution or high-speed data enable paths |
| Input Hysteresis | 250mV typ at VCC = 3.0V - rejects >200mV of common-mode noise on GPIO lines in industrial handhelds |
| ESD Rating | 2kV HBM, 1kV CDM - exceeds IEC 61000-4-2 Level 2 for consumer product front-panel interfaces |
Pinout & Package
X1-DFN1010-6 (1.0mm × 1.0mm × 0.5mm, 0.35mm pad pitch) - leadless, bottom-terminated package with exposed thermal pad; requires solder paste stencil design per AP02001 for reliable reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power return reference; must be connected to solid ground plane for EMI suppression and stable logic thresholds |
| 2 | A | Non-inverting digital input; Schmitt-triggered to tolerate slow edges and reduce metastability risk |
| 3 | NC | No internal connection - left floating or tied to GND per layout best practice to prevent parasitic coupling |
| 4 | VCC | Primary power supply; decoupling capacitor (100nF X7R) required within 2mm for transient current stability |
| 5 | Y | Push-pull buffered output; drives high/low actively without pull-up resistors; compatible with 1.2V–3.3V logic families |
| 6 | NC | No internal connection - electrically isolated; no routing or thermal relief needed |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC < 0.9µA enables integration into always-on wake-up circuits without compromising battery runtime |
| IOFF partial power-down | Prevents backflow current when VCC = 0V but input remains at valid logic level - essential for hot-swap and rail-isolation designs |
| Schmitt-trigger inputs | 250mV hysteresis eliminates need for external RC filters on noisy board traces or flex-cable interfaces |
| Wide VCC range | 0.8V–3.6V operation allows direct use with buck-boost regulators in wearables without intermediate LDOs |
| Lead-free & green compliance | Fully RoHS-compliant, halogen- and antimony-free - meets IPC-1752A material declaration requirements for EU/China markets |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G34DBVR | Higher ICC (10µA typ), no IOFF, 1.65–5.5V VCC range | Lacks partial power-down capability; unsuitable for multi-rail sequencing | Select only if operating above 1.65V and IOFF is not required |
| 74AUP1G34FS3-7 | Same die, different package (X2-DFN0808-4, 0.8mm × 0.8mm) | Smaller footprint but lower thermal resistance (θJA = 430°C/W vs. 435°C/W) | Choose for ultra-dense layouts where 0.2mm size reduction outweighs marginal thermal trade-off |
Compared with SN74LVC1G34DBVR, the 74AUP1G34FW5-7 offers 10× lower static current and critical IOFF for power-gated systems; versus 74AUP1G34FS3-7, it trades 0.2mm in size for slightly better thermal performance and identical electrical behavior-making FW5 optimal for balanced density/thermal designs.

FAQ
What is the maximum recommended operating temperature for continuous use?
The 74AUP1G34FW5-7 is rated for continuous operation from –40°C to +125°C ambient temperature. Its junction-to-ambient thermal resistance (θJA = 435°C/W) means that at 100mW power dissipation, junction temperature rises ~43.5°C above ambient-well within the +150°C absolute maximum TJ limit under typical PCB layouts with minimal copper area.
Can this device drive a 50Ω transmission line directly?
Yes-its ±4mA output drive at 3.0V corresponds to ~750Ω effective output impedance, allowing direct termination into 50Ω loads with controlled rise/fall times. At 3.3V, measured tPLH/tPHL is 2.1ns (typ) into 5pF, confirming adequate bandwidth for ≤200MHz digital signaling without external buffering.
Is the NC pin electrically isolated or internally tied?
Pins 3 and 6 are confirmed as No Connection (NC) with no internal bond wire or silicon connection. They are fully isolated-neither tied to VCC, GND, nor any internal node-and may be left unconnected, grounded, or used as thermal relief pads without affecting functionality or reliability.
Does the Schmitt-trigger input affect propagation delay consistency?
No-the Schmitt-trigger stage is integrated into the input buffer's first stage and does not add variable delay. Propagation delay (tpd) remains tightly specified across voltage and temperature: 1.0–3.2ns (3.3V, CL=5pF) with ±0.3ns variation over –40°C to +125°C, verified in DS35155 Rev.5 switching characteristics tables.
