Product details
Overview
SN74AUP1G07DBVT 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 range, delivers 3.3 ns max propagation delay at 3.3 V, supports Ioff partial-power-down protection, and features 1.5 pF typical input capacitance - enabling use in portable medical sensors and embedded interface buses.
For engineers reviewing the SN74AUP1G07DBVT datasheet, SN74AUP1G07DBVT pinout, SN74AUP1G07DBVT application, or SN74AUP1G07DBVT equivalent, key selection criteria include its ultra-low ICC (0.9 µA max), open-drain compatibility with wired-OR bus topologies, 3.6-V I/O tolerance for mixed-voltage signal interfacing, and SOT-23-5 package suitability for space-constrained PCB layouts.
Technical Context
The SN74AUP1G07DBVT implements a CMOS-based non-inverting buffer stage with open-drain output, requiring an external pull-up resistor to define high-level logic state. Its Ioff circuitry actively disables outputs when VCC = 0 V, preventing back-drive current during hot insertion or partial power-down sequences.
Input hysteresis (250 mV typ at 3.3 V) improves noise immunity against slow-rising signals, while low dynamic power consumption (Cpd = 1 pF typ at 3.3 V) and sub-1 µA quiescent current support energy-sensitive applications such as wearable biometric monitors and low-duty-cycle sensor nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface with 0.9-V microcontrollers, 1.2-V FPGAs, and 3.3-V peripherals without level shifters. |
| tpd Max | 3.3 ns at 3.3 V, CL = 5 pF - ensures timing-critical signal buffering in high-speed serial control lines (e.g., I²C pull-up extensions). |
| ICC Max | 0.9 µA at 3.6 V - reduces standby power in always-on sensor subsystems, extending battery life in portable diagnostics equipment. |
| Ioff | 0.6 µA max at 0 V VCC - guarantees safe live insertion into powered-backplane systems and prevents latch-up during power sequencing. |
| Input Hysteresis | 250 mV typ at 3.3 V - tolerates noisy or slow-switching inputs from mechanical switches, analog comparators, or long PCB traces. |
| IO Max | ±20 mA per output - supports driving moderate capacitive loads (e.g., 1000-pF bus stubs) and LED indicators without external drivers. |
| ESD Rating | 2000-V HBM, 1000-V CDM - meets industrial handling requirements for automated assembly and field-replaceable modules. |
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 plating, MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NC) | No internal connection | Unused pad; must remain unconnected - no routing or thermal relief required. |
| 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 system ground plane. |
| 4 (Y) | Open-drain output | Active-low output requiring external pull-up; sinks up to 20 mA; compatible with wired-AND bus architectures. |
| 5 (VCC) | Power supply | Single-supply rail for core logic; bypass capacitor (0.1 µF ceramic) mandatory within 2 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low static power | ICC ≤ 0.9 µA max enables multi-year operation on coin-cell batteries in remote health monitors. |
| Open-drain output architecture | Supports bidirectional bus arbitration and voltage-level translation between 1.2-V controllers and 3.3-V peripherals. |
| Ioff partial-power-down | Prevents destructive back-current flow when SN74AUP1G07DBVT is unpowered but connected to active system buses. |
| Input hysteresis | 250 mV threshold margin eliminates chatter on mechanically debounced switch inputs or noisy analog comparator outputs. |
| 3.6-V I/O tolerance | Allows direct connection to legacy 3.3-V logic without series resistors, simplifying BOM and layout in mixed-voltage designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar buffer/level-shifter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G07DBVT | Wider VCC range (1.65–5.5 V); higher ICC (10 µA typ); no Ioff; faster tpd (2.5 ns @ 3.3 V) | Better suited for 5-V legacy systems; unsuitable for sub-1-V operation or hot-swap scenarios | Select when interfacing with 5-V peripherals and higher speed is critical; avoid for battery-critical or partial-power-down designs. |
| 74AHC1G07SE-7 | Same VCC range (2–5.5 V); higher drive strength (±8 mA); no Ioff; higher Cpd (3 pF) | Targeted at industrial PLC I/O modules; lacks 0.8-V operation and Ioff protection | Choose for robust 3.3/5-V industrial control where ESD tolerance and wide temp range matter more than ultra-low power. |
Compared with SN74LVC1G07DBVT and 74AHC1G07SE-7, the SN74AUP1G07DBVT uniquely balances sub-1-µA standby current, 0.8-V operability, and Ioff-enabled live insertion - making it the only viable choice for next-generation ultra-low-power portable medical and IoT edge devices.

FAQ
What is the maximum recommended load capacitance for SN74AUP1G07DBVT to maintain 3.3 ns propagation delay?
The SN74AUP1G07DBVT achieves 3.3 ns max tpd at 3.3 V with CL = 5 pF, as specified in Section 7.6 of the datasheet. At CL = 10 pF, tpd increases to 4.5 ns max; at CL = 30 pF, it reaches 10.4 ns max. For timing-critical paths, keep total node capacitance ≤ 5 pF using short traces and minimal stubs.
Does SN74AUP1G07DBVT support true bidirectional communication like I²C?
No - the SN74AUP1G07DBVT is a unidirectional non-inverting buffer with open-drain output. While its open-drain structure allows wired-OR bus sharing (e.g., interrupt lines), it lacks built-in direction control or dual I/O capability. True bidirectional protocols require dedicated transceivers such as the PCA9515A.
Can SN74AUP1G07DBVT be used without an external pull-up resistor?
No - the SN74AUP1G07DBVT has an open-drain output and cannot drive a logic-high state internally. An external pull-up resistor (typically 1–10 kΩ to VCC or another rail) is mandatory to establish defined HIGH levels. Omitting it results in floating or undefined output states.
What is the purpose of the NC pin (Pin 1) on SN74AUP1G07DBVT?
Pin 1 of the SN74AUP1G07DBVT is a no-connect terminal with no internal bond wire or silicon connection. It must remain unconnected - neither routed nor tied to GND/VCC. This pin exists for mechanical symmetry and package compatibility, not functional use.
How does the Ioff feature of SN74AUP1G07DBVT protect during partial power-down?
The Ioff circuitry in SN74AUP1G07DBVT disables output drivers when VCC = 0 V, limiting leakage current to ≤ 0.6 µA even if input/output pins are biased to 3.3 V. This prevents damaging reverse current flow through the device during hot-plug events or staggered power sequencing in modular systems.
