Product details
Overview
74AUP1G34SE-7 from Diodes Incorporated is a single non-inverting buffer gate in the Advanced Ultra Low Power (AUP) CMOS logic family, designed for signal conditioning and level translation 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 includes Schmitt-trigger inputs with ~250mV hysteresis at VCC = 3.0V - enabling robust interfacing in noisy or slow-rising input environments such as mobile sensor hubs.
For engineers reviewing the 74AUP1G34SE-7 datasheet, 74AUP1G34SE-7 pinout, 74AUP1G34SE-7 application, or 74AUP1G34SE-7 equivalent, key selection criteria include ultra-low ICC (<0.9µA), wide VCC range compatibility, guaranteed IOFF behavior during power sequencing, and verified performance across -40°C to +125°C ambient temperature.
Technical Context
This device implements a positive Boolean function (Y = A) using advanced low-threshold CMOS transistors optimized for sub-1V operation. Its IOFF circuit actively disables output terminals when VCC = 0V, preventing back-current flow into powered-down subsystems - critical for multi-rail portable architectures.
The integrated Schmitt-trigger input provides noise immunity with defined hysteresis (~250mV at 3.0V), allowing reliable operation with slow-edge signals from microcontrollers, sensors, or mechanical switches without external RC filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8V to 3.6V - supports direct interface with 1.2V, 1.8V, 2.5V, and 3.3V logic domains without level shifters. |
| Output Drive | ±4mA at VCC = 3.0V - sufficient to drive multiple standard CMOS loads or short PCB traces without signal degradation. |
| Static Current (ICC) | <0.9µA max at +25°C - enables multi-year battery life in always-on wake-up circuits or IoT endpoint nodes. |
| IOFF Leakage | <0.6µA at VCC = 0V - ensures safe isolation between powered and unpowered sections during sleep mode transitions. |
| Propagation Delay | 1.0ns min / 3.2ns typ at 3.3V, CL = 5pF - meets timing requirements for high-speed control signaling in compact embedded systems. |
| Input Hysteresis | ~250mV at VCC = 3.0V - rejects up to ±125mV of common-mode noise on input lines, eliminating false triggering. |
| ESD Rating | 2000V HBM, 1000V CDM - exceeds JEDEC standards for handling robustness in automated assembly and field deployment. |
Pinout & Package
SOT353 (2.0mm × 2.0mm × 1.1mm, 0.65mm pitch) - leadless, RoHS-compliant surface-mount package with exposed pad thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for all internal circuitry and output stage return path. |
| 2 | A | Single digital input with Schmitt-trigger action; accepts slow or noisy signals without oscillation. |
| 3 | NC | No connection - internally unconnected; must remain floating or tied to GND/VCC per layout guidelines. |
| 4 | VCC | Primary power supply rail; powers logic core and output buffer; supports dynamic voltage scaling. |
| 5 | Y | Inverting-buffered output with push-pull structure; drives high/low actively without pull-up resistors. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC < 0.9µA enables use in energy-harvesting or coin-cell-powered applications where quiescent current dominates lifetime. |
| IOFF partial power-down | Prevents destructive back-current when VCC = 0V while other system rails remain active - essential for USB-C port controllers and PMIC sequencers. |
| Schmitt-trigger input | Hysteresis ~250mV at 3.0V eliminates need for external debouncing components in switch interfaces or rotary encoder signal conditioning. |
| Wide VCC tolerance | 0.8V–3.6V operation allows seamless integration across legacy 1.2V SoCs and modern 3.3V peripherals without voltage translation ICs. |
| Lead-free & green compliance | Fully RoHS-compliant, halogen- and antimony-free construction meets IPC-1752A material declaration requirements for global OEM programs. |
Applications
| Mobile Sensor Interface | USB Type-C Port Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-buffer gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G34DBVR | Wider VCC range (1.65–5.5V); higher ICC (10µA typical); no IOFF; no Schmitt input. | Better suited for mixed-voltage industrial boards with 5V peripherals but lacks battery-safety IOFF and noise immunity. | Select when interfacing with 5V logic and thermal constraints allow higher static power. |
| 74AHC1G34GW,125 | Higher speed (tpd = 2.5ns @ 3.3V); VCC = 2–5.5V; no IOFF; no Schmitt input; higher CPD (12pF). | Preferred in high-frequency clock distribution paths where propagation delay dominates over power budget. | Choose only if system requires sub-3ns timing and can tolerate absence of IOFF and Schmitt-trigger robustness. |
Compared with SN74LVC1G34DBVR and 74AHC1G34GW,125, the 74AUP1G34SE-7 uniquely combines ultra-low ICC, guaranteed IOFF, and Schmitt-trigger input - making it the sole option for safety-critical, battery-constrained, noise-prone applications like wearable health monitors and portable diagnostic tools.

FAQ
What is the maximum recommended operating temperature for 74AUP1G34SE-7?
The device is fully specified from -40°C to +125°C ambient temperature. At TA = +125°C, electrical parameters including VOH, VOL, and tPD remain within datasheet limits, and thermal resistance (θJA = 371°C/W for SOT353) ensures junction temperature stays below 150°C under typical PCB layouts with 2oz copper.
Can 74AUP1G34SE-7 be used with 0.9V supply voltage?
Yes - the device is explicitly characterized down to 0.8V VCC. At 0.9V, it maintains valid VIH/VIL thresholds (VIH ≥ 0.72V, VIL ≤ 0.27V), delivers >1mA output drive, and retains IOFF functionality. Propagation delay increases to ~12ns (CL = 5pF), which remains acceptable for most control-signaling applications.
Is the NC pin on 74AUP1G34SE-7 required to be grounded?
No - Pin 3 (NC) is internally unconnected and must not be soldered to any net. Per Diodes' AP02002 layout guide, it should remain electrically floating; tying it to GND or VCC may cause parasitic coupling or violate package stress specifications.
Does 74AUP1G34SE-7 support hot insertion?
Yes - the combination of IOFF (preventing back-current during VCC ramp-up/down) and 2kV HBM ESD protection enables safe hot-plug operation in modular systems. However, full hot-swap compliance requires external current-limiting circuitry on VCC and controlled slew-rate on input signals per IEC 61000-4-2 Level 4.
