Product details
Overview
SN74AUP1G07DSFR from Texas Instruments is a single non-inverting buffer/driver 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 range, delivers <0.9 µA quiescent current, achieves 2.2 ns typical propagation delay at 3.3 V, and supports Ioff for live insertion-used in CPAP machines, barcode scanners, and embedded PC I/O expansion.
For engineers reviewing the SN74AUP1G07DSFR datasheet, SN74AUP1G07DSFR pinout, SN74AUP1G07DSFR application, or SN74AUP1G07DSFR equivalent, key selection criteria include its 0.8–3.6 V operation, open-drain output compatibility with wired-AND/wired-OR bus topologies, ultra-low ICC, Ioff-enabled partial-power-down capability, and SON (DSF) 6-pin 1.45 mm × 1.00 mm package footprint.
Technical Context
The SN74AUP1G07DSFR implements a CMOS-based single-buffer architecture with open-drain output stage, enabling active-low wired-OR and active-high wired-AND configurations when multiple outputs share a common pull-up. Its input hysteresis (250 mV typ at 3.3 V) improves noise immunity for slow-rising signals.
It features Ioff circuitry that disables output paths when VCC = 0 V, preventing back-drive current and supporting hot-plug operation. The device is fully characterized from –40°C to +85°C, with 3.6-V I/O tolerance allowing down-translation from higher-voltage peripherals to sub-1.2-V microcontrollers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 0.8 V to 3.6 V - enables direct interface with 0.8-V core logic, 1.8-V I/O, and 3.3-V peripherals without external level shifters. |
| Quiescent Current (ICC) | 0.9 µA max at 3.3 V - extends battery life in always-on sensor nodes and portable medical devices. |
| Propagation Delay (tpd) | 2.2 ns max at 3.3 V, CL = 5 pF - supports high-speed point-to-point signaling in compact embedded interfaces. |
| Ioff Current | 0.6 µA max at 0 V VCC - ensures safe live insertion and prevents back-current damage during partial power-down. |
| Input Hysteresis (Vhys) | 250 mV typ at 3.3 V - tolerates slow or noisy input transitions without chatter, critical in mechanical switch debouncing. |
| Output Drive (IOL) | 4 mA min at 3 V - sufficient to drive standard 10-kΩ pull-ups for I²C-compatible buses or LED indicators. |
| Input Capacitance (Ci) | 1.5 pF typ - minimizes loading on high-impedance source signals such as crystal oscillator outputs or sensor amplifiers. |
Pinout & Package
SN74AUP1G07DSFR uses the SON (DSF) package: 6-pin, 1.45 mm × 1.00 mm body, 0.5-mm pitch, wettable flank terminations. Pin 1 is marked by a dot; pins are numbered counterclockwise from top-left corner in top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connection (N.C.) | Internally unconnected; must be left floating or tied to GND per layout best practice-no electrical function. |
| 2 | Input A | CMOS-compatible digital input with hysteresis; accepts 0–3.6 V regardless of VCC, enabling mixed-voltage interfacing. |
| 3 | GND | Ground reference for all internal circuitry and output stage; requires low-inductance connection to system ground plane. |
| 4 | Output Y | Open-drain NMOS output; requires external pull-up to define logic HIGH; supports wired-logic and bus arbitration. |
| 5 | VCC | Primary power supply input; bypass with 0.1 µF ceramic capacitor placed within 2 mm of pin for stable low-noise operation. |
| 6 | No Connection (N.C.) | Internally unconnected; no routing or soldering required; may be used as thermal pad anchor if grounded per DSF mechanical spec. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 0.9 µA max enables multi-year operation from coin-cell batteries in IoT endpoint sensors. |
| Open-drain output | Supports bidirectional bus protocols (e.g., I²C), wired-AND logic, and voltage-level translation without direction control pins. |
| Ioff support | Prevents current backflow when VCC = 0 V, allowing safe hot-swap in modular industrial controllers and field-replaceable modules. |
| Input hysteresis | 250 mV threshold margin eliminates false triggering from EMI or contact bounce in medical front-end switches and HVAC controls. |
| 0.8–3.6 V operation | Single device replaces multiple voltage-tier buffers, simplifying BOM and reducing PCB area in multi-rail embedded systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DSFR | Higher ICC (10 µA typ), wider VCC range (1.65–5.5 V), no Ioff, no hysteresis. | Not suitable for partial-power-down or noisy sensor inputs; better for general-purpose 3.3/5-V logic buffering. | Select when interfacing legacy 5-V peripherals and lower cost is prioritized over ultra-low power. |
| NC7SZ07P5X | Smaller SOT-353 (5-pin) package, ICC = 1 µA max, no Ioff, VCC = 1.65–5.5 V, no hysteresis. | Lacks live-insertion support and noise immunity; limited to stable, clean 3.3-V environments. | Choose for space-constrained consumer electronics where Ioff and hysteresis are not required. |
Compared with SN74LVC1G07DSFR and NC7SZ07P5X, SN74AUP1G07DSFR uniquely combines sub-1-µA quiescent current, Ioff-enabled hot-swap, input hysteresis, and 0.8-V operation-making it the only option qualified for battery-critical, mixed-voltage, and field-serviceable medical and industrial designs.

FAQ
What is the maximum operating temperature for SN74AUP1G07DSFR?
The SN74AUP1G07DSFR is rated for operation from –40°C to +85°C ambient temperature. This industrial-grade range is validated per JEDEC JESD22-A108 and supports deployment in medical devices like CPAP machines and blood pressure monitors where thermal stability is critical. The SON (DSF) package's thermal resistance (RθJA = 407.1°C/W) ensures reliable performance under continuous load at maximum junction temperature.
Does SN74AUP1G07DSFR support I²C bus interfacing?
Yes, SN74AUP1G07DSFR supports I²C-compatible operation due to its open-drain output and 3.6-V I/O tolerance. When configured with an external pull-up resistor on Output Y, it can serve as a level translator between 1.2-V microcontroller GPIOs and 3.3-V I²C peripherals. Its 250 mV input hysteresis also improves noise margin on shared SDA/SCL lines in electrically noisy environments.
What is the purpose of the N.C. pins on SN74AUP1G07DSFR?
SN74AUP1G07DSFR has two No Connection (N.C.) pins-Pin 1 and Pin 6-in its 6-pin SON (DSF) package. These pins have no internal silicon connection and serve mechanical or thermal roles only. Per TI's DSF mechanical drawing, Pin 6 may be used as a thermal pad anchor if soldered to a copper pour, but neither pin must be connected for functional operation.
Can SN74AUP1G07DSFR drive a 10-kΩ pull-up resistor reliably?
Yes, SN74AUP1G07DSFR can reliably drive a 10-kΩ pull-up resistor. At VCC = 3.3 V and IOL = 4 mA (minimum specified), the output voltage drop (VOL) remains ≤0.45 V, ensuring a valid LOW logic level. This meets standard I²C and SMBus requirements and supports direct interface with common LED indicators and optocoupler inputs without additional buffering.
How does the Ioff feature of SN74AUP1G07DSFR improve system reliability?
The Ioff feature in SN74AUP1G07DSFR disables output paths when VCC = 0 V, limiting off-state leakage to ≤0.6 µA. This prevents damaging back-current flow from powered peripherals into unpowered sections-critical during hot-swap events in modular medical equipment or field-replaceable industrial modules. It eliminates the need for external isolation components and ensures compliance with JEDEC JESD78 latch-up Class II requirements.
