Product details
Overview
SN74AUP1G07DCKT 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 SN74AUP1G07DCKT datasheet, SN74AUP1G07DCKT pinout, SN74AUP1G07DCKT application, or SN74AUP1G07DCKT equivalent, key selection criteria include its 0.8–3.6 V VCC range, open-drain output compatibility with 3.6-V-tolerant inputs, ultra-small SC70-5 package (2.0 mm × 1.25 mm), and verified Ioff behavior enabling partial-power-down operation.
Technical Context
The SN74AUP1G07DCKT implements a CMOS-based single-buffer architecture with no internal pull-up; output requires external pull-up for logic-high assertion. Its input hysteresis (250 mV typ at 3.3 V) improves noise immunity against slow-rising signals, while low dynamic power (Cpd = 1 pF typ at 3.3 V) minimizes switching energy in high-frequency data paths.
Designed for mixed-voltage interfacing, it accepts 3.6-V-tolerant inputs independent of VCC, enabling down-translation from 3.3-V peripherals to 1.0–1.2-V microcontrollers. The Ioff feature disables output current flow when VCC = 0 V, preventing back-drive during hot-plug events or system power sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface between sub-1-V logic and 3.3-V systems without level shifters. |
| tpd Max | 3.3 ns at 3.3 V, CL = 5 pF - supports >100 MHz signal routing in compact timing-critical paths. |
| ICC Max | 0.9 µA at 3.6 V - extends battery life in always-on sensor nodes and wearable health monitors. |
| Ioff Max | 0.6 µA at 0 V VCC - blocks damaging back-current during partial power-down or live insertion. |
| Input Hysteresis | 250 mV typical at 3.3 V - rejects EMI and accommodates slow GPIO transitions in industrial control inputs. |
| Output Drive | ±20 mA sink capability - drives standard 10-kΩ pull-ups or interfaces directly with I²C bus loads. |
| ESD Rating | 2000-V HBM, 1000-V CDM - meets robustness requirements for handheld and field-deployable equipment. |
Pinout & Package
SN74AUP1G07DCKT uses the SC70-5 (DCK) package: 2.00 mm × 1.25 mm body, 0.65 mm height, 0.65 mm lead pitch, and wettable flank leads for automated optical inspection. Pin 1 is marked by a dot; Pin 3 is GND; Pin 5 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connection (NC) | Internally unconnected - must be left floating or tied to GND/VCC per layout guidelines; no electrical function. |
| 2 | Input A | CMOS-compatible digital input with 3.6-V tolerance and 250-mV hysteresis - accepts slow or noisy control signals. |
| 3 | GND | Primary ground reference for all internal circuitry and I/O - requires low-inductance connection to system ground plane. |
| 4 | Output Y | Open-drain NMOS output - sinks current only; requires external pull-up to define logic-high voltage level. |
| 5 | VCC | Single power supply input - bypass with 0.1-µF ceramic capacitor placed within 2 mm of pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 0.9 µA across full 0.8–3.6 V range - eliminates quiescent drain in always-on IoT edge nodes. |
| Open-drain output | Supports wired-AND/OR logic and I²C/SMBus compatibility - enables multi-master bus arbitration without external components. |
| Ioff protection | Blocks current flow on I/O pins when VCC = 0 V - allows safe board insertion into powered-backplane systems. |
| 3.6-V I/O tolerance | Accepts input voltages up to 3.6 V regardless of VCC setting - simplifies voltage translation from legacy 3.3-V peripherals. |
| Low-noise switching | Overshoot/undershoot <10% of VCC - maintains signal integrity in noise-sensitive analog-front-end interfaces. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DCKT | Higher ICC (10 µA typ), wider VCC (1.65–5.5 V), no Ioff support | Suitable for higher-speed 5-V systems but lacks live-insertion safety | Choose when 5-V compatibility is required and partial-power-down is not needed. |
| TC7SZ07FU,EL | Lower drive (8 mA), smaller USON-5 package (1.6 × 1.6 mm), same 0.8–3.6 V range | Better space-constrained fit but reduced sink current limits reliability with heavy pull-ups | Prefer for ultra-dense PCBs where 20-mA sink margin is unnecessary. |
Compared with SN74LVC1G07DCKT and TC7SZ07FU,EL, SN74AUP1G07DCKT uniquely combines sub-1-µA quiescent current, Ioff-enabled hot-swap capability, and 20-mA sink strength - making it optimal for battery-critical, mixed-voltage, and field-serviceable designs.

FAQ
What is the maximum sink current capability of the SN74AUP1G07DCKT output?
The SN74AUP1G07DCKT output can sink up to ±20 mA continuously, as specified in its Absolute Maximum Ratings table. This allows direct driving of standard pull-up resistors (e.g., 10 kΩ at 3.3 V yields 0.33 mA) or interfacing with I²C bus loads without external buffering. Exceeding this limit risks latch-up or parametric shift over time.
Does SN74AUP1G07DCKT support level translation between 3.3 V and 1.2 V domains?
Yes, SN74AUP1G07DCKT supports bidirectional level translation in open-drain configurations: its 3.6-V-tolerant input accepts 3.3-V signals while powered from 1.2 V, and its open-drain output can be pulled up to 3.3 V independently. No direction-control pin is needed, simplifying interface design for mixed-voltage sensor hubs.
Can SN74AUP1G07DCKT be used in I²C bus applications?
Yes, SN74AUP1G07DCKT is commonly deployed as an I²C bus extender or voltage translator due to its open-drain output, 3.6-V I/O tolerance, and low input capacitance (1.5 pF). When configured with appropriate pull-ups, it preserves I²C timing margins and supports standard-mode (100 kHz) and fast-mode (400 kHz) operation across voltage domains.
What is the purpose of the NC pin (Pin 1) on SN74AUP1G07DCKT?
Pin 1 of SN74AUP1G07DCKT is a No Connection (NC) terminal with no internal bond wire or circuit connection. It may be left unconnected, tied to GND for mechanical stability, or routed to a test point - but it must never be driven or loaded, as it serves no functional role in the device's logic or power path.
How does the Ioff feature of SN74AUP1G07DCKT improve system reliability?
The Ioff feature in SN74AUP1G07DCKT disables output current flow when VCC = 0 V, preventing back-driving of powered-down sections by active signals on A or Y pins. This protects downstream logic during hot-swap events, power sequencing mismatches, or partial system resets - a critical safeguard in modular medical and industrial equipment.
