Product details
Overview
SN74AUP1G07DBVRG4 from Texas Instruments is a single non-inverting buffer with open-drain output, designed for level translation and wired-OR logic in ultra-low-power systems. It operates across 0.8 V to 3.6 V supply, delivers 3.3 ns max propagation delay at 3.3 V, draws ≤0.9 µA ICC, and supports Ioff for live insertion-used in portable medical sensors and battery-powered interface circuits.
For engineers reviewing the SN74AUP1G07DBVRG4 datasheet, SN74AUP1G07DBVRG4 pinout, SN74AUP1G07DBVRG4 application, or SN74AUP1G07DBVRG4 equivalent, key selection criteria include its 0.8–3.6 V VCC range, open-drain drive capability up to 20 mA, input hysteresis (250 mV typ), Ioff-enabled partial-power-down operation, and SOT-23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The SN74AUP1G07DBVRG4 implements a CMOS-based single-buffer architecture with no internal pull-up; its open-drain output requires external pull-up for logic high assertion. Input hysteresis (250 mV typ at 3.3 V) enables robust operation with slow-rising signals and noise immunity in noisy environments like industrial sensor interfaces.
It features Ioff circuitry that disables outputs when VCC = 0 V, preventing back-drive current and enabling hot-plug capability. The device is fully characterized from –40°C to +85°C and supports 3.6-V I/O tolerance-allowing safe interfacing between 3.3-V peripherals and sub-1-V microcontrollers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - Enables direct interface with 0.8-V ASICs, 1.2-V microcontrollers, and 3.3-V peripherals without level shifters. |
| tpd (max) | 3.3 ns at 3.3 V, CL = 5 pF - Supports >100 MHz signal routing in point-to-point digital control paths. |
| ICC (max) | 0.9 µA at 3.6 V - Delivers multi-year battery life in always-on wearable and IoT endpoint nodes. |
| IOL (min) | 4 mA at 3.0 V - Drives standard 10-kΩ pull-up resistors to 3.3 V while maintaining VOL ≤ 0.45 V. |
| Input Hysteresis | 250 mV typical at 3.3 V - Rejects >250 mV of switching noise on input lines, eliminating need for external RC filtering. |
| Ioff Current | 0.6 µA max at 3.6 V - Ensures <1 µA leakage during system sleep mode, critical for energy harvesting designs. |
| ESD Rating | ±2000 V HBM - Meets IEC 61000-4-2 Level 2 for handheld and field-deployable equipment. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, 0.95 mm pitch, lead-free NiPdAu finish, RoHS-compliant, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused pad; must be left floating or grounded per layout guidelines-no electrical function. |
| 2 (A) | Input | CMOS-compatible digital input with hysteresis; accepts 0–3.6 V regardless of VCC setting. |
| 3 (GND) | Ground reference | Primary return path for all internal logic and output current; requires low-inductance connection to PCB ground plane. |
| 4 (Y) | Open-drain output | Active-low sinking output only; requires external pull-up resistor to define logic-high voltage level. |
| 5 (VCC) | Power supply | Single supply input for core logic; bypass capacitor (0.1 µF) required within 2 mm for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 0.9 µA ensures negligible quiescent drain in always-on sensor wake-up circuits. |
| Open-drain output architecture | Enables wired-AND bus sharing and mixed-voltage level translation without direction control pins. |
| Ioff partial-power-down support | Blocks back-current flow when VCC = 0 V-enables hot-swap capability in modular instrumentation systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVR | Wider VCC range (1.65–5.5 V); higher ICC (10 µA typ); no Ioff; no hysteresis. | Requires ≥1.65 V supply; unsuitable for sub-1-V systems or hot-swap scenarios. | Select when interfacing legacy 5-V logic or when higher drive strength (32 mA) outweighs power penalty. |
| 74AHC1G07GW,125 | NXP variant: same AUP-equivalent speed/power; identical 0.8–3.6 V range; Ioff supported; different marking and MSL rating (Level-3). | Compatible pinout and electrical behavior; validated for automotive AEC-Q200 stress testing. | Choose for automotive-grade qualification or dual-sourcing where TI and NXP supply continuity is strategic. |
Compared with SN74LVC1G07DBVR, the SN74AUP1G07DBVRG4 offers 10× lower ICC and Ioff support-critical for battery longevity and live-insertion safety-while matching open-drain functionality. Against 74AHC1G07GW,125, it provides identical low-power performance but differs in qualification scope and packaging traceability.

FAQ
What is the maximum output sink current for SN74AUP1G07DBVRG4?
The SN74AUP1G07DBVRG4 supports a continuous output sink current of ±20 mA per output pin. At VCC = 3.0 V and IOL = 4 mA, the output voltage remains ≤0.45 V-ensuring reliable low-state assertion when driving standard 10-kΩ pull-ups to 3.3 V. Exceeding 20 mA risks thermal overstress and parametric shift.
Does SN74AUP1G07DBVRG4 support true bidirectional level shifting?
No, SN74AUP1G07DBVRG4 is a unidirectional buffer with open-drain output only-it does not support automatic bidirectional translation. It can translate low-voltage inputs (e.g., 0.8 V) to higher-voltage outputs (e.g., 3.3 V via external pull-up), but cannot pass signals upstream. For bidirectional use, discrete MOSFET translators or dedicated level shifters like TXS0102 are required.
Can SN74AUP1G07DBVRG4 operate with VCC = 0 V while signals are present on A or Y pins?
Yes. SN74AUP1G07DBVRG4 includes Ioff circuitry that disables the output stage and limits input/output leakage to ≤0.6 µA when VCC = 0 V. This allows safe "live insertion" into powered-backplane systems and prevents damaging back-current flow-verified per JESD78 Class II latch-up testing (>100 mA).
What is the purpose of the NC pin (Pin 1) on SN74AUP1G07DBVRG4?
Pin 1 of SN74AUP1G07DBVRG4 is a no-connect (NC) terminal with no internal silicon connection. It may be left floating, tied to GND, or used as a mechanical anchor-TI confirms no electrical function or timing impact. Layout best practice recommends grounding it to reduce EMI susceptibility in high-density routing.
How does input hysteresis improve noise immunity in SN74AUP1G07DBVRG4?
SN74AUP1G07DBVRG4 features 250 mV typical input hysteresis at 3.3 V, meaning the VIH threshold is ~250 mV higher than VIL. This creates a noise margin that prevents multiple toggles during slow or noisy transitions-critical for interfacing with analog sensors, mechanical switches, or long PCB traces where ringing or crosstalk exceeds 100 mV.
