Product details
Overview
SN74AUP3G34DQER from Texas Instruments is a low-power triple non-inverting buffer gate in an 8-pin X2SON (DQE) package, operating across 0.8 V to 3.6 V supply range, delivering 4.3 ns max propagation delay at 3.3 V with 4.3 pF typical dynamic power dissipation. It supports mixed-mode I/O (3.6-V tolerant), partial-power-down via Ioff, and is optimized for battery-powered portable systems requiring ultra-low static current (≤0.9 µA).
For engineers reviewing the SN74AUP3G34DQER datasheet, SN74AUP3G34DQER pinout, SN74AUP3G34DQER application, or SN74AUP3G34DQER equivalent, key selection criteria include its 0.8–3.6 V wide VCC range, Ioff-enabled partial-power-down capability, 1.5 pF typical input capacitance, and suitability for point-to-point signal buffering in space-constrained, low-power embedded interfaces.
Technical Context
The SN74AUP3G34DQER implements three independent non-inverting buffer functions (Y = A) with rail-to-rail output swing and CMOS-compatible input thresholds that scale with VCC. Its logic diagram confirms direct input-to-output mapping without inversion or enable control.
Designed for ultra-low power, it features sub-1 µA static ICC across full VCC range and maintains low dynamic power (Cpd = 4.3 pF typ at 3.3 V) while meeting JESD 78 Class II latch-up performance (>100 mA). Ioff circuitry actively disables outputs during power-down to prevent backflow current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables single-supply operation across legacy 1.2 V, 1.8 V, 2.5 V, and 3.3 V domains with mixed-voltage interface support. |
| tpd Max | 4.3 ns at 3.3 V, CL = 15 pF - ensures fast signal integrity for high-speed point-to-point routing in compact PCB layouts. |
| ICC Max | 0.9 µA at TA = 25°C - extends battery life in always-on sensor nodes and wearable devices by minimizing quiescent drain. |
| Ioff | ≤0.6 µA at 0 V - allows safe isolation of powered-down sections without external blocking components in multi-rail systems. |
| Input Capacitance | 1.5 pF typical - reduces loading on preceding drivers and preserves signal edge rate in high-frequency digital paths. |
| IOH/IOL | ±4 mA at 3 V - provides sufficient drive strength for fanout-1 buffering without external level-shifting or amplification. |
| ESD Rating | 2000-V HBM, 1000-V CDM - meets industrial-grade robustness requirements for handling and board-level reliability. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A (Input) | First buffer input; accepts 0.8–3.6 V logic levels with VCC-scaled VIH/VIL thresholds. |

| 3 | 3A (Input) | Third buffer input; identical electrical characteristics to Pins 1 and 2. |
| 4 | GND | Ground reference for all logic and power domains; must be connected to system ground plane. |
| 5 | VCC | Primary supply rail; powers all three buffers; supports decoupling capacitor placement adjacent to Pin 5. |
| 6 | 1Y (Output) | Non-inverted output of Buffer 1; rail-to-rail swing from GND to VCC; drives capacitive loads ≤30 pF. |
| 7 | 2Y (Output) | Non-inverted output of Buffer 2; independently driven; no shared output stage with other Y pins. |
| 8 | 3Y (Output) | Non-inverted output of Buffer 3; fully buffered output with same timing and drive specs as Pins 6 and 7. |
Key Features
| Feature | Design Value |
|---|---|
| NanoStar™-compatible X2SON packaging | 1.4 mm × 1.2 mm footprint with exposed thermal pad - enables ultra-dense layout in wearables and IoT edge nodes. |
| Ioff partial-power-down support | Active output disable when VCC = 0 V - eliminates need for external isolation switches in hot-plug or sleep-mode subsystems. |
| 3.6-V I/O tolerance | Inputs and outputs withstand up to 3.6 V regardless of VCC setting - simplifies level translation in mixed-voltage FPGA/ASIC interfaces. |
| Low-noise switching | Overshoot/undershoot <10% of VCC - reduces EMI and signal integrity risk in noise-sensitive analog-mixed-signal environments. |
| Wide temperature operation | –40°C to +85°C ambient range - qualified for industrial and automotive cabin applications without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G34DQER | Higher ICC (max 10 µA), 1.65–5.5 V VCC range, no Ioff, 32 ns tpd at 3.3 V | Lacks partial-power-down; suited for higher-speed, non-battery-critical designs | Select when wider VCC range and legacy 5 V compatibility outweigh ultra-low power needs. |
| SN74AUC3G34DQER | Lower VCC range (0.8–2.7 V), faster tpd (2.3 ns at 2.5 V), no 3.6-V I/O tolerance | Not suitable for 3.3 V I/O domains; requires strict sub-2.7 V system design | Choose only if system operates exclusively below 2.7 V and demands sub-3 ns propagation delay. |
Compared with SN74LVC3G34DQER and SN74AUC3G34DQER, the SN74AUP3G34DQER uniquely balances ultra-low static power (<0.9 µA), 3.6-V I/O tolerance, and Ioff support-making it the sole option among the three for battery-powered, mixed-voltage, partial-power-down systems.

FAQ
What is the maximum propagation delay of the SN74AUP3G34DQER at 3.3 V?
The SN74AUP3G34DQER has a maximum propagation delay (tpd) of 4.3 ns at VCC = 3.3 V with CL = 15 pF, measured from input transition to output transition crossing VCC/2. This value is guaranteed across –40°C to +85°C and reflects worst-case timing for design margining in high-reliability applications.
Does the SN74AUP3G34DQER support partial-power-down mode?
Yes, the SN74AUP3G34DQER supports partial-power-down mode via its Ioff feature. When VCC = 0 V, the Ioff circuitry disables all three outputs, limiting off-state current to ≤0.6 µA and preventing damaging backflow current into powered-down sections of the system.
What is the input voltage tolerance of the SN74AUP3G34DQER relative to VCC?
The SN74AUP3G34DQER inputs are 3.6-V tolerant regardless of VCC setting - meaning they accept VI up to 3.6 V even when VCC is as low as 0.8 V. This enables seamless interfacing with higher-voltage controllers without external level-shifting circuitry.
Can the SN74AUP3G34DQER operate at 1.2 V supply voltage?
Yes, the SN74AUP3G34DQER is fully specified for operation at 1.2 V (within its 0.8 V to 3.6 V VCC range). At 1.2 V, it delivers tpd ≤12.8 ns (CL = 5 pF), ICC ≤0.9 µA, and VIH/VIL thresholds scaled to 0.75×VCC and 0.35×VCC respectively - ensuring robust logic behavior in ultra-low-voltage subsystems.
What package type and dimensions does the SN74AUP3G34DQER use?
The SN74AUP3G34DQER uses the X2SON-8 (DQE) package: 1.4 mm × 1.2 mm body size, 0.4 mm maximum height, with an exposed thermal pad on the underside. Pin 1 is located in the top-left corner (Q1 quadrant) per JEDEC-standard tape orientation.
