Product details
Overview
SN74AUP3G34YFPR from Texas Instruments is a low-power triple non-inverting buffer gate in an 8-ball DSBGA (YFP) 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 and 0.9 µA max static ICC - optimized for battery-powered portable logic interfacing.
For engineers reviewing the SN74AUP3G34YFPR datasheet, SN74AUP3G34YFPR pinout, SN74AUP3G34YFPR application, or SN74AUP3G34YFPR equivalent, this page provides verified functional identity, YFP-package–specific terminal mapping, Ioff-enabled partial-power-down capability, and validated alternatives for point-to-point signal buffering in ultra-low-power systems.
Technical Context
The SN74AUP3G34YFPR implements three independent positive-logic buffers (Y = A) with rail-to-rail input compatibility and 3.6-V tolerant I/Os, enabling mixed-voltage domain interfacing. Its AUP-family architecture delivers sub-1-µA static current across full VCC range and supports Ioff isolation during partial power-down.
Signal integrity is maintained via low input capacitance (1.5 pF typ), low output overshoot/undershoot (<10% of VCC), and latch-up immunity exceeding 100 mA per JESD 78 Class II - critical for noise-sensitive portable and wearable applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface with 0.9-V, 1.2-V, 1.8-V, 2.5-V, and 3.3-V logic domains without level shifters. |
| tpd (Max) | 4.3 ns at 3.3 V, CL = 15 pF - ensures timing-critical signal routing in high-speed digital subsystems with minimal latency. |
| ICC (Max) | 0.9 µA at TA = 25°C - extends battery life in always-on sensor nodes and IoT edge devices by minimizing quiescent drain. |
| Ioff Support | Active at VCC = 0 V - prevents backflow current when powered down, allowing safe hot-insertion and multi-rail sequencing. |
| Input Capacitance | 1.5 pF typical - reduces loading on preceding drivers and preserves signal edge rates in high-impedance or long-trace paths. |
| Output Drive | ±4 mA at 3.0 V - sufficient for driving one standard CMOS load or short PCB traces without external buffering. |
| ESD Rating | 2000-V HBM, 1000-V CDM - meets industrial-grade robustness requirements for handheld and field-deployable equipment. |
Pinout & Package
SN74AUP3G34YFPR uses an 8-ball DSBGA (NanoStar™ YFP) package with 0.4-mm pitch, 1.2 mm × 1.2 mm body, and solder-bump-defined terminals. Pin 1 is identified by a distinct bump composition marker (• = Pb-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 (Pin 1) | 1A Input | First buffer input; accepts 0.8–3.6 V logic levels and tolerates up to 4.6 V transient voltage. |
| A2 (Pin 2) | 1Y Output | Non-inverted output of first buffer; drives downstream loads with ±4 mA capability at 3 V. |
| B1 (Pin 3) | 2A Input | Second buffer input; electrically isolated from other inputs; supports independent signal routing. |
| B2 (Pin 4) | 2Y Output | Non-inverted output of second buffer; shares same VCC/GND rails but no internal coupling. |
| C1 (Pin 5) | 3A Input | Third buffer input; fully compatible with 0.8-V minimum VCC operation and Ioff shutdown mode. |
| C2 (Pin 6) | 3Y Output | Non-inverted output of third buffer; maintains <10% VCC overshoot/undershoot under fast switching. |
| D1 (Pin 7) | GND | Ground reference for all logic and I/O circuits; must be connected to system ground plane for EMI control. |
| D2 (Pin 8) | VCC | Supply rail for all buffers; decoupling capacitor (≥100 nF) required within 2 mm of this ball for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| NanoStar™ DSBGA packaging | 1.2 mm × 1.2 mm footprint with 0.4-mm pitch - enables ultra-compact layout in space-constrained wearables and medical sensors. |
| Wide VCC range (0.8–3.6 V) | Eliminates need for external voltage translators when interfacing between legacy and modern low-voltage SoCs. |
| Ioff partial-power-down | Disables outputs and blocks current flow when VCC = 0 V - essential for multi-supply domain power gating. |
| Low dynamic power (Cpd = 4.3 pF) | Reduces switching energy consumption by >50% vs. older AUC/AHC families at 3.3 V, lowering thermal load. |
| 3.6-V I/O tolerance | Allows safe connection to 3.3-V peripherals even when operating at 1.8-V VCC - simplifies mixed-signal board design. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC3G34DCUR | Higher ICC (max 10 µA), wider tpd range (2.5–7.5 ns), 1.65–5.5 V VCC range, VSSOP-8 package. | Supports 5-V systems and higher-speed interfaces but consumes ~11× more static power than SN74AUP3G34YFPR. | Select when 5-V compatibility or legacy board reuse is required; avoid for sub-µA battery lifetime targets. |
| SN74AUP2G34YFPR | Dual (not triple) buffer, identical AUP family specs, same YFP-8 package and 0.8–3.6 V operation. | Provides two independent buffers instead of three - suitable only where channel count reduction is acceptable. | Choose when system requires exactly two buffered paths and board area is constrained; verify pinout alignment before substitution. |
Compared with SN74LVC3G34DCUR, SN74AUP3G34YFPR delivers 90% lower static current and smaller footprint, while SN74AUP2G34YFPR trades one buffer channel for identical ultra-low-power performance in the same package.

FAQ
What is the maximum propagation delay of SN74AUP3G34YFPR at 3.3 V?
The maximum propagation delay (tpd) of SN74AUP3G34YFPR is 4.3 ns at VCC = 3.3 V ± 0.3 V with CL = 15 pF and TA = –40°C to 85°C. This value is specified under worst-case process/voltage/temperature conditions and ensures timing margin for high-reliability portable designs. The SN74AUP3G34YFPR achieves this while maintaining sub-1-µA static current - a key differentiator versus standard LVC-family buffers.
Does SN74AUP3G34YFPR support partial power-down operation?
Yes, SN74AUP3G34YFPR supports partial power-down via its Ioff feature: when VCC = 0 V, the outputs enter high-impedance state and block current flow from live inputs, preventing damaging backflow. This behavior is tested and guaranteed per datasheet Section 6.5 (Ioff = 0.2–0.6 µA at VCC = 0 V). The SN74AUP3G34YFPR thus enables safe multi-rail sequencing in battery-powered systems where subsystems power up/down independently.
What is the package type and size of SN74AUP3G34YFPR?
SN74AUP3G34YFPR uses a NanoStar™ DSBGA (YFP) package: 8-ball, 0.4-mm pitch, 1.2 mm × 1.2 mm body size, 0.5-mm max height, with Pb-free SnAgCu solder bumps. Pin 1 is marked by a distinct bump composition (•). This package eliminates leads entirely, reducing parasitic inductance and enabling direct die-to-board mounting - ideal for miniaturized wearable and medical devices where board space is at a premium. The SN74AUP3G34YFPR footprint is significantly smaller than equivalent VSSOP or uQFN variants.
Can SN74AUP3G34YFPR interface between 1.8-V and 3.3-V logic domains?
Yes, SN74AUP3G34YFPR supports mixed-voltage interfacing: it operates from VCC = 0.8 V to 3.6 V and features 3.6-V tolerant I/Os. When powered at 1.8 V, its inputs accept 0–3.6 V signals, and outputs swing rail-to-rail (0–1.8 V), allowing direct connection to 3.3-V receivers with appropriate pull-up configuration. This eliminates level-shifters in many portable designs. The SN74AUP3G34YFPR's guaranteed VIH/VIL thresholds across VCC ensure reliable switching even at 1.2-V or 0.9-V supply - a capability not found in standard LVC buffers.
What are the absolute maximum ratings for SN74AUP3G34YFPR?
The absolute maximum ratings for SN74AUP3G34YFPR are: VCC = –0.5 V to 4.6 V; VI/VO = –0.5 V to 4.6 V (output in high-Z or power-off); VO = –0.5 V to VCC + 0.5 V (output driven); continuous output current = ±20 mA; continuous VCC/GND current = ±50 mA. Exceeding these may cause permanent damage. These limits are defined per JEDEC JESD78 and validated across process corners. The SN74AUP3G34YFPR's 4.6-V input tolerance enables robust handling of transient overvoltage events common in portable charging and docking scenarios.
