Product details
Overview
74AUP1G34FS3-7 from Diodes Incorporated is a single-channel CMOS buffer gate with push-pull output, designed for ultra-low-power operation across 0.8V–3.6V supply rails. It delivers ±4mA drive at 3.0V, features IOFF partial-power-down protection, and integrates Schmitt-trigger inputs (250mV hysteresis at VCC = 3.0V) for robust noise immunity in portable battery-powered systems such as e-readers and GPS receivers.
For engineers reviewing the 74AUP1G34FS3-7 datasheet, 74AUP1G34FS3-7 pinout, 74AUP1G34FS3-7 application, or 74AUP1G34FS3-7 equivalent, key selection criteria include its sub-1µA static ICC, 3.2ns typical propagation delay at 3.3V/CL=5pF, IOFF-enabled power sequencing capability, and X2-DFN0808-4 package compatibility with high-density PCB layouts.
Technical Context
This device implements a non-inverting logic function (Y = A) using advanced ultra-low-power (AUP) CMOS process technology. Its Schmitt-trigger input stage provides defined switching thresholds and tolerance to slow-rising/falling signals, while the IOFF circuit actively disables output leakage when VCC = 0V - enabling safe back-drive prevention during partial power-down sequences in multi-rail systems.
The buffer operates across industrial temperature range (−40°C to +125°C) and supports dynamic loading up to 30pF. Propagation delay scales predictably with supply voltage and load capacitance: 3.2ns (typ) at 3.3V/5pF, increasing to 7.2ns (typ) at same voltage with 30pF load - critical for timing-critical signal buffering in low-voltage microcontroller I/O expansion paths.
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 translation. |
| Output Drive Strength | ±4mA at VCC = 3.0V - sufficient to drive multiple standard CMOS loads or short PCB traces without signal degradation. |
| Static Supply Current | ICC < 0.9µA - minimizes quiescent power draw in always-on subsystems like real-time clock buffers or sensor wake-up circuits. |
| Propagation Delay | 3.2ns typical at VCC = 3.3V, CL = 5pF - supports >100MHz signal routing in low-latency control paths. |
| Input Hysteresis | 250mV typical at VCC = 3.0V - rejects noise on slow-switching signals (e.g., mechanical switch debouncing, battery monitor outputs). |
| IOFF Leakage | ≤0.6µA at VCC = 0V - prevents destructive current flow when this buffer is powered off while connected to active system buses. |
| ESD Rating | 2kV HBM, 1kV CDM - meets IEC 61000-4-2 Level 2 requirements for handheld consumer electronics assembly and field use. |
Pinout & Package
X2-DFN0808-4 is a 0.8mm × 0.8mm × 0.35mm leadless chip-scale package with diamond-pattern 0.5mm pad pitch and bottom-side thermal pad. Pin 1 identification is marked by a laser-etched dot adjacent to corner pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry; must be connected to low-impedance system ground plane for stable operation and EMI suppression. |
| 2 | A | CMOS-compatible digital input with Schmitt-trigger threshold; accepts 0.8V–3.6V logic levels regardless of VCC. |
| 3 | NC | No internal connection; electrically isolated - may be left floating or tied to GND for mechanical stability. |
| 4 | VCC | Primary power supply rail; decoupling capacitor (100nF ceramic) required within 2mm for noise immunity and transient response. |
| 5 | Y | Push-pull CMOS output driving full rail-to-rail swing; capable of sourcing/sinking ±4mA at 3.0V with <0.45V VOL and >2.6V VOH. |
| 6 | NC | No internal connection; electrically isolated - may be left floating or tied to GND for mechanical stability. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC < 0.9µA ensures negligible battery drain in always-on monitoring nodes (e.g., lid-open detection in notebooks). |
| IOFF partial-power-down | Blocks bidirectional current flow when VCC = 0V - essential for hot-plug interfaces and multi-voltage domain isolation. |
| Schmitt-trigger inputs | 250mV hysteresis eliminates chatter on noisy or slowly transitioning signals (e.g., thermistor-based analog comparator outputs). |
| Wide VCC operating range | 0.8V–3.6V support enables direct integration into energy-harvesting systems and legacy 3.3V/2.5V infrastructure without external regulators. |
| Lead-free & halogen-free | Meets RoHS 2 and JEDEC JS709C green standards (<900ppm Br+Cl, <1000ppm Sb) for global environmental compliance. |

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 Schmitt trigger, IOFF not supported | Lacks noise immunity and power-down safety; requires external pull-up/down for unused inputs | Select only if cost is primary constraint and system lacks partial-power-down requirements |
| 74AUP1G07FS3-7 | Open-drain output instead of push-pull; requires external pull-up resistor | Suitable for wired-OR bus applications but adds component count and limits drive strength | Choose only when bus arbitration or mixed-voltage open-drain signaling is required |
Compared with SN74LVC1G34DBVR and 74AUP1G07FS3-7, the 74AUP1G34FS3-7 uniquely combines ultra-low ICC, Schmitt-trigger input noise rejection, and IOFF-enabled safe power sequencing - making it optimal for battery-constrained, multi-rail portable systems where reliability and power efficiency are co-primary design goals.

FAQ
What is the maximum capacitive load the 74AUP1G34FS3-7 can drive while maintaining specified propagation delay?
The device is characterized up to 30pF load capacitance. At 3.3V supply, typical tPD increases from 3.2ns (CL = 5pF) to 7.2ns (CL = 30pF). Driving >30pF risks violating timing margins in high-speed paths and may require series termination or buffer staging.
Can the NC pins on the X2-DFN0808-4 package be used for thermal relief or grounding?
No - pins 3 and 6 are internally unconnected and electrically isolated. They may be left floating or tied to GND solely for mechanical reinforcement during reflow; connecting them to any active net risks unintended coupling or solder bridging due to their proximity to GND and VCC pads.
Does the 74AUP1G34FS3-7 support mixed-voltage operation where input exceeds VCC?
No - absolute maximum input voltage is VCC + 0.5V. Applying an input > VCC + 0.5V (e.g., 3.3V input to 1.8V-powered device) violates absolute ratings and risks latch-up or permanent damage. Use level translators for cross-voltage domain interfacing.
How does the Schmitt-trigger input affect timing analysis in synchronous designs?
The hysteresis introduces asymmetric threshold voltages (VIH ≈ 2.0V, VIL ≈ 0.9V at VCC = 3.0V), which delays recognition of rising edges relative to falling edges. This must be accounted for in setup/hold calculations when interfacing with clocks or data strobes exhibiting slow slew rates.
