Product details
Overview
SN74AUP1G240 from Texas Instruments is a low-power single inverter with 3-state output, designed for voltage-level translation and bus isolation in portable electronics. It operates across 0.8 V to 3.6 V, delivers 4.7 ns max propagation delay at 3.3 V, consumes ≤0.9 µA ICC, and supports Ioff partial power-down mode - enabling use in battery-powered medical sensors and industrial I/O modules.
For engineers reviewing the SN74AUP1G240 datasheet, SN74AUP1G240 pinout, SN74AUP1G240 application, or SN74AUP1G240 equivalent, key selection criteria include its 3-state active-low OE control, 1.5 pF input capacitance, 3.6-V I/O tolerance, latch-up immunity (>100 mA), and NanoStar™ SOT-23 (DBV) package compatibility with space-constrained PCB layouts.
Technical Context
The SN74AUP1G240 implements a single inverting buffer with active-low 3-state output enable (OE), performing Y = A̅. Its CMOS inputs include built-in hysteresis for noise immunity on slow transitions, and clamp diodes protect against negative transients up to –0.5 V.
It features Ioff circuitry that disables outputs and limits leakage to ≤0.6 µA when VCC = 0 V, enabling safe back-driving in partial-power-down systems. The balanced push-pull output drives ±20 mA while maintaining <10% overshoot/undershoot relative to VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interfacing between 0.8-V microcontrollers and 3.3-V peripherals without level shifters. |
| tpd Max | 4.7 ns at 3.3 V - ensures timing-critical signal inversion meets sub-5-ns budget in high-speed control loops. |
| ICC Max | 0.9 µA - extends battery life in always-on wearable health monitors by minimizing quiescent current drain. |
| Ioff Max | 0.6 µA at –40°C to +85°C - prevents damaging back-current during hot-swap or staged power sequencing in modular systems. |
| CI Typ | 1.5 pF - reduces capacitive loading on high-impedance sensor nodes, preserving signal integrity in analog front-end interfaces. |
| IO Max | ±20 mA - drives LED indicators or small logic loads directly without external buffers in compact IoT edge nodes. |
| ESD HBM | 2000 V - meets IEC 61000-4-2 Level 2 requirements for robustness in factory automation human-touch interfaces. |
Pinout & Package
SN74AUP1G240DBVR uses the 5-pin SOT-23 (DBV) package, measuring 1.60 mm × 2.90 mm, with exposed pad not present and RoHS-compliant matte-tin lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OE | Active-low output enable input | Drives output Y to high-impedance state when high; must be pulled up to VCC via external resistor during power-up/down to guarantee Z-state. |
| 2 - A | Inverter input | Accepts CMOS logic levels from 0.8 V to 3.6 V; supports floating when OE = high due to input-disable feature. |
| 3 - GND | Ground reference | Primary return path for all internal currents; requires low-inductance connection to minimize ground bounce in mixed-signal systems. |
| 4 - Y | Inverted 3-state output | Delivers A̅ when OE = low; enters high-Z when OE = high - enabling shared-bus arbitration in point-to-point data links. |
| 5 - VCC | Positive supply | Supplies core logic and output drivers; decoupling capacitor (100 nF) required within 3 mm for stable operation at 3.3 V. |
Key Features
| Feature | Design Value |
|---|---|
| Input hysteresis | Enables reliable switching with slow-rising signals (e.g., thermistor-based thresholds) without external Schmitt triggers. |
| Ioff partial power-down | Prevents current backflow into powered-down sections of multi-rail systems, eliminating need for isolation switches in portable diagnostics equipment. |
| 3.6-V I/O tolerance | Allows 3.3-V peripherals to drive A or Y pins safely even when VCC = 0.8 V - simplifying voltage translation in heterogeneous SoC interfaces. |
| NanoStar™ packaging | Reduces board area by >40% vs. standard SOT-23, supporting ultra-compact designs like hearing aid firmware update circuits. |
| Low noise (<10% VCC overshoot) | Minimizes EMI in sensitive RF co-location environments such as Bluetooth LE medical telemetry transceivers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar inverter-with-3-state-output applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G04DBVR | Higher ICC (1 µA typ), narrower VCC range (1.65–5.5 V), no Ioff support | Not suitable for partial-power-down systems; requires external isolation for hot-swap | Choose only if operating above 1.65 V and Ioff is unnecessary |
| SN74AHC1G04DBVR | Higher drive strength (±8 mA), higher Cpd (10 pF), no 3.6-V I/O tolerance | Cannot interface 3.3-V signals when VCC = 0.8–1.2 V; unsuitable for ultra-low-voltage translation | Select when faster edges (2.5 ns tpd) are needed and VCC ≥ 2 V is guaranteed |
Compared with SN74LVC1G04DBVR and SN74AHC1G04DBVR, the SN74AUP1G240DBVR uniquely combines sub-1-µA static current, 0.8-V operation, Ioff protection, and 3.6-V I/O tolerance - making it the only viable option for battery-powered systems requiring mixed-voltage interoperability and zero-power-state safety.

FAQ
What is the function of the OE pin on the SN74AUP1G240DBVR?
The OE (output enable) pin on the SN74AUP1G240DBVR is an active-low control input. When OE is low, the device performs inversion (Y = A̅); when OE is high, the output Y enters a high-impedance (3-state) condition. To ensure reliable high-Z behavior during power-up/down, OE must be tied to VCC via an external pullup resistor - minimum value determined by the driver's sink capability per TI's application guidance. This behavior is explicitly defined in the SN74AUP1G240DBVR function table and timing diagrams.
Does the SN74AUP1G240DBVR support partial power-down operation?
Yes, the SN74AUP1G240DBVR fully supports partial power-down operation via its Ioff feature. When VCC = 0 V, both inputs and outputs enter a high-impedance state with leakage current limited to ≤0.6 µA over temperature. This prevents back-current flow into powered-down sections of multi-rail systems - a critical requirement validated in TI's Electrical Characteristics table (Ioff parameter) and explicitly cited in the SN74AUP1G240DBVR Detailed Description section 8.3.4.
What is the maximum propagation delay for the SN74AUP1G240DBVR at 3.3 V?
The maximum propagation delay (tpd) for the SN74AUP1G240DBVR at 3.3 V is 4.7 ns, measured under CL = 5 pF and TA = –40°C to +85°C conditions. This value is specified in Table 6.6 (Switching Characteristics: CL = 5 pF) of the official datasheet and represents worst-case performance across full temperature and voltage ranges - confirming timing suitability for sub-5-ns-critical paths in portable control systems.
Can the SN74AUP1G240DBVR accept input voltages higher than its VCC supply?
Yes, the SN74AUP1G240DBVR supports over-voltage tolerant inputs up to 4.6 V (absolute maximum rating), regardless of VCC level - enabling safe interfacing of 3.3-V signals even when VCC = 0.8 V. This capability is documented in Section 6.1 (Absolute Maximum Ratings) and reinforced in Feature Description 8.3.5, allowing direct connection to legacy peripherals without external clamping or level-shifting circuitry.
What package type does the SN74AUP1G240DBVR use, and what are its dimensions?
The SN74AUP1G240DBVR uses the 5-pin SOT-23 (DBV) package, with nominal body dimensions of 1.60 mm × 2.90 mm. This NanoStar™ package is explicitly listed in the Device Information table of the datasheet and confirmed in the Pin Configuration and Functions section. Its compact footprint supports high-density PCB layouts in space-constrained applications such as hearing aids and smart patches.
