Product details
Overview
SN74AUP1G34DRLR from Texas Instruments is a single low-power CMOS buffer gate performing Y = A logic, operating across 0.8 V to 3.6 V supply, with 4.1 ns max propagation delay at 3.3 V, 4.1 pF typical dynamic power capacitance, and 0.9 μA max quiescent current - deployed in ultra-compact SOT-5X3 packaging for space-constrained portable and battery-powered signal conditioning.
For engineers reviewing the SN74AUP1G34DRLR datasheet, SN74AUP1G34DRLR pinout, SN74AUP1G34DRLR application, or SN74AUP1G34DRLR equivalent, key selection criteria include Ioff-enabled live insertion support, 3.6-V I/O tolerance for mixed-voltage level translation, input hysteresis (250 mV typ at 3.3 V) for noise immunity, and ultra-low static/dynamic power consumption in sub-1-mm² footprint designs.
Technical Context
This device belongs to TI's AUP (Advanced Ultra-Low-Power) logic family, engineered specifically for battery-operated systems requiring extended runtime without sacrificing signal integrity. Its architecture integrates input hysteresis, rail-to-rail I/O tolerance, and Ioff circuitry enabling safe partial-power-down operation.
The SN74AUP1G34DRLR implements a non-inverting buffer with balanced output drive, optimized for point-to-point connections in low-noise environments. It supports down-translation (e.g., 3.3-V inputs to 1.0-V microcontrollers) and exhibits overshoot/undershoot <10% of VCC due to controlled edge rates.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface with sub-1-V processors and legacy 3.3-V peripherals |
| tpd Max | 4.1 ns at 3.3 V, CL = 5 pF - ensures timing-critical signal buffering with minimal latency |
| ICC Max | 0.9 μA - reduces standby power draw in always-on sensor nodes and wearables |
| Cpd | 4.1 pF typ at 3.3 V - lowers dynamic switching energy and EMI in high-frequency clock/data paths |
| Ioff | 0.6 μA max - prevents back-drive current when VCC = 0 V, supporting hot-plug and power-gating |
| VIH/VIL | VIH = 2.0 V min, VIL = 0.9 V max at VCC = 3.3 V - guarantees robust logic-level recognition across voltage margins |
| Input Hysteresis | 250 mV typ at 3.3 V - rejects slow-rising or noisy inputs without external Schmitt triggers |
Pinout & Package
SOT-5X3 (DRL) package: 1.6 mm × 1.2 mm body, 0.5-mm pitch, 5-pin surface-mount with exposed thermal pad (non-electrical), rated MSL-1, RoHS-compliant, NIPDAU/NIPDAUAG finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No-connect (NC) | Internally unconnected - must be left floating or tied to GND/VCC per layout best practice; no electrical function |
| 2 | Input A | CMOS-compatible digital input with hysteresis; accepts 0–3.6 V regardless of VCC value |
| 3 | GND | Primary ground reference for logic and power domains; required for stable operation and ESD path |
| 4 | Output Y | Push-pull CMOS output capable of ±4 mA drive at 3.3 V; rail-to-rail swing with low overshoot |
| 5 | VCC | Single-supply rail (0.8–3.6 V); powers internal logic and enables Ioff protection when de-energized |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-small footprint | 0.64 mm² DPW-equivalent area in SOT-5X3 - saves >40% board space vs. standard SOT-23 |
| Ioff partial-power-down | Enables live insertion and prevents back-current flow when VCC = 0 V - critical for modular hot-swap systems |
| 3.6-V I/O tolerance | Accepts inputs up to 3.6 V independent of VCC - simplifies level-shifting between 1.0-V SoCs and 3.3-V sensors |
| Low-noise output edges | Overshoot/undershoot <10% of VCC - eliminates need for external termination in point-to-point traces |
| Input hysteresis | 250 mV typ at 3.3 V - tolerates slow-switching analog-like signals (e.g., thermistor outputs) without oscillation |
Applications
| Medical Sensor Interface | Portable Audio Signal Path |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G34DCKR | Higher ICC (10 µA typ), narrower VCC range (1.65–5.5 V), no Ioff, faster tpd (3.5 ns) | Not suitable for sub-1-V operation or live-insertion; better for 3.3/5-V only systems with tighter timing budgets | Select when speed > power savings and full rail compatibility is required |
| 74AHC1G34SE-7 | Higher drive strength (±8 mA), wider VCC (2–5.5 V), no hysteresis, no Ioff, Cpd = 15 pF | Unsuited for battery-powered or mixed-voltage translation; preferred in industrial 5-V logic buses | Choose for legacy 5-V systems needing stronger fanout and higher noise immunity via external filtering |
Compared with SN74LVC1G34DCKR and 74AHC1G34SE-7, the SN74AUP1G34DRLR uniquely delivers sub-1-μA quiescent current, 0.8-V operation, and Ioff protection - making it the only viable option for energy-harvesting sensors and ultra-portable electronics where every nanoamp matters.

FAQ
What is the maximum operating temperature for SN74AUP1G34DRLR?
The SN74AUP1G34DRLR is rated for continuous operation from –40°C to +85°C ambient temperature, validated per JEDEC JESD22-A108. Thermal resistance data (RθJA = 349.7°C/W for DRL package) confirms reliable performance under sustained load in enclosed industrial enclosures and handheld medical devices where airflow is limited.
Does SN74AUP1G34DRLR support level translation between 1.2 V and 3.3 V domains?
Yes, the SN74AUP1G34DRLR supports bidirectional level translation: its inputs tolerate up to 3.6 V regardless of VCC, and its output swings rail-to-rail. When powered at 1.2 V, it correctly interprets 3.3-V inputs and drives 1.2-V logic levels - enabling seamless interface between modern ultra-low-voltage microcontrollers and legacy 3.3-V peripherals without external translators.
Can SN74AUP1G34DRLR be used with floating inputs?
No - all unused inputs of the SN74AUP1G34DRLR must be tied to VCC or GND to prevent undefined logic states and increased current consumption. The datasheet explicitly requires this per TI application report SCBA004; floating inputs may cause oscillation, excessive ICC, or latch-up in CMOS logic structures.
What is the purpose of the NC pin (Pin 1) on SN74AUP1G34DRLR?
Pin 1 of the SN74AUP1G34DRLR is a no-connect terminal with no internal bond wire or silicon connection. It may be left unconnected, tied to GND for mechanical stability, or routed to VCC if needed for PCB symmetry - but it carries zero electrical function and contributes no signal integrity benefit or risk when left floating.
How does the Ioff feature of SN74AUP1G34DRLR protect system-level designs?
The Ioff circuitry in the SN74AUP1G34DRLR disables both input and output buffers when VCC = 0 V, limiting leakage current to ≤0.6 μA. This prevents damaging back-current flow from live 3.3-V signal lines into a powered-down subsystem - enabling safe hot-swap of modules, partial power gating in multi-rail systems, and compliance with IEC 61000-4-2 ESD immunity requirements.
