Product details
Overview
SN74AUP1G07DBVR from Texas Instruments is a single non-inverting buffer with open-drain output, designed for low-voltage logic translation and level-shifting in battery-powered systems. It operates across 0.8 V to 3.6 V supply, delivers 3.3 ns max propagation delay at 3.3 V, consumes ≤0.9 µA ICC, and supports Ioff for live insertion-used in barcode scanners, CPAP machines, and embedded PC I/O expansion.
For engineers reviewing the SN74AUP1G07DBVR datasheet, SN74AUP1G07DBVR pinout, SN74AUP1G07DBVR application, or SN74AUP1G07DBVR equivalent, key selection criteria include its ultra-low static/dynamic power (ICC ≤ 0.9 µA, Cpd = 1 pF), 0.8–3.6 V wide VCC range, open-drain compatibility with wired-AND/wired-OR bus topologies, and SOT-23-5 package with 2.90 mm × 1.60 mm footprint.
Technical Context
The SN74AUP1G07DBVR implements a CMOS-based single-buffer architecture with open-drain output stage, enabling bidirectional voltage translation and bus arbitration without external pull-ups in some configurations. Its input hysteresis (250 mV typ at 3.3 V) improves noise immunity for slow-rising signals in noisy industrial sensor interfaces.
It features Ioff circuitry that disables outputs when VCC = 0 V, preventing back-drive current during partial power-down-critical for hot-swap applications like modular ATCA solutions and field-transmitter signal conditioning. The device is fully specified from –40°C to 85°C and rated for 100 mA latch-up per JESD78 Class II.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interfacing between sub-1 V microcontrollers and 3.3 V peripherals without external level shifters. |
| tpd (max) | 3.3 ns at 3.3 V, CL = 5 pF - supports high-speed point-to-point signaling in compact portable devices like e-books and wireless headsets. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Must be left unconnected; no electrical function or thermal path - avoids unintended coupling in high-density layouts. |
| 2 (A) | Input | CMOS-compatible digital input with hysteresis; accepts 0–3.6 V regardless of VCC, enabling down-translation from 3.3 V to 1.2 V domains. |
| 3 (GND) | Ground reference | Primary return path for all internal logic and output current; must be connected to system ground plane with low-inductance trace. |
| 4 (Y) | Open-drain output | Active-low sinking output requiring external pull-up; supports wired-AND bus structures and I²C-compatible signaling. |
| 5 (VCC) | Power supply | Supplies core logic and output driver; bypass capacitor (0.1 µF) required within 2 mm for stable operation under dynamic load. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ICC | ≤0.9 µA max at 3.6 V - reduces quiescent power in always-on IoT edge nodes and wearable health monitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/level-shifter 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; 3.5 ns tpd at 3.3 V. | Not suitable for sub-1.65 V operation or hot-swap; better for 5 V legacy systems. | Select when interfacing with 5 V peripherals and full-power operation is acceptable. |
| 74AHC1G07SE-7 | Same 0.8–3.6 V range; higher drive (±25 mA); no Ioff; 2.8 ns tpd at 3.3 V; SOT-23-5 package. | Lacks live-insertion support; less suited for partial-power-down systems. | Prefer when maximum speed and drive strength are prioritized over Ioff and ultra-low ICC. |
Compared with SN74LVC1G07DBVR and 74AHC1G07SE-7, the SN74AUP1G07DBVR uniquely balances sub-1 V operation, <1 µA quiescent current, and Ioff-enabled hot-swap-making it optimal for battery-critical, modular, and mixed-voltage embedded designs where power sequencing and layout density are constrained.

FAQ
What is the maximum operating temperature for SN74AUP1G07DBVR?
The SN74AUP1G07DBVR is rated for continuous operation from –40°C to +85°C ambient temperature, validated per JEDEC JESD22-A104 thermal cycling and JESD22-A108 high-temperature storage tests. This range supports deployment in medical devices like CPAP machines and industrial field transmitters exposed to variable environmental conditions. The SOT-23-5 package's RθJA of 298.6°C/W ensures adequate thermal margin under typical PCB copper pour conditions.
Does SN74AUP1G07DBVR support level shifting between 1.2 V and 3.3 V domains?
Yes, the SN74AUP1G07DBVR supports bidirectional level shifting: its 3.6-V tolerant inputs accept 3.3 V signals even when VCC = 1.2 V, and its open-drain output can be pulled up to 3.3 V while driven by a 1.2 V logic source. This enables seamless interface between modern ultra-low-voltage MCUs and legacy 3.3 V peripherals without external translators - confirmed in TI's Application Report SCBA004 and Figure 5 of SCES591J.
Can SN74AUP1G07DBVR be used in I²C bus applications?
Yes, the SN74AUP1G07DBVR's open-drain output and Ioff functionality make it suitable for I²C bus extension and voltage-level translation. When configured with appropriate pull-up resistors on the Y pin, it replicates standard I²C open-drain behavior. Its 250 mV input hysteresis suppresses noise on shared SDA/SCL lines, and Ioff prevents bus contention during power sequencing - verified in TI's I²C Bus Guide SLVA689.
What is the purpose of the NC pin (Pin 1) on SN74AUP1G07DBVR?
Pin 1 of the SN74AUP1G07DBVR is a no-connect (NC) terminal with no internal silicon connection. It must remain unconnected - neither tied to VCC nor GND - to avoid parasitic coupling or unintended capacitance that could degrade signal integrity in high-frequency or low-noise applications. TI's mechanical drawings and Pin Functions table in SCES591J explicitly define this pin as "No Connection" for the DBV package.
How does the Ioff feature of SN74AUP1G07DBVR improve system reliability?
The Ioff feature in SN74AUP1G07DBVR disables output drivers when VCC = 0 V, blocking reverse current flow from powered I/O lines into the unpowered IC. This prevents latch-up, overheating, and data corruption during hot-swap events in modular systems like ATCA boards or field-replaceable sensor modules. Tested per JESD78 Class II, it enables safe live insertion without requiring external isolation circuitry - a key differentiator versus standard LVC or AHC buffers.
