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 5-pin X2SON package (0.80 mm × 0.80 mm), active-low OE control, 3.6-V I/O tolerance, input hysteresis for noise immunity, and verified performance down to 0.8 V supply.
Technical Context
The SN74AUP1G240 implements a single inverting buffer with active-low 3-state enable logic (Y = A when OE = L; Y = Z when OE = H). Its CMOS inputs feature built-in hysteresis (≈100 mV typical) and support floating inputs when OE is high, eliminating external pull resistors in disabled state.
It uses TI's AUP (Advanced Ultra-Low-Power) process, delivering balanced push-pull output drive (±20 mA), 1.5 pF typical input capacitance, and Ioff protection that limits leakage to ≤0.6 µA over –40°C to +85°C when VCC = 0 V - critical for hot-swap and multi-rail system interoperability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface between 0.8-V core logic and 3.3-V peripherals without level shifters |
| tpd Max | 4.7 ns at 3.3 V - ensures timing compliance in high-speed point-to-point data paths up to ~100 MHz |
| ICC Max | 0.9 µA - extends battery life in always-on sensor nodes and wearable health monitors |
| Ioff Max | 0.6 µA at –40°C to +85°C - prevents back-current damage during partial power-down in mixed-voltage systems |
| Input Hysteresis | ≈100 mV - rejects switching noise on slow-rising control lines (e.g., microcontroller GPIOs driving OE) |
| IOH/IOL | ±20 mA - drives moderate capacitive loads (≤30 pF) without external buffers in compact PCB layouts |
| Cpd | 4.2 pF at 3.3 V - minimizes dynamic power in clocked or toggling signal paths |
Pinout & Package
X2SON-5 package (0.80 mm × 0.80 mm, 0.40 mm pitch), ultra-compact footprint optimized for space-constrained portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low output enable input | Drives output Y to high-impedance when logic HIGH; requires pull-up to VCC for power-up safety |
| 2 (A) | Inverter input | Accepts 0.8–3.6 V signals; supports floating state when OE = H due to input-disable feature |
| 3 (GND) | Ground reference | Return path for all internal logic and output current; must be low-inductance connection |
| 4 (Y) | Inverted 3-state output | Drives inverted A when OE = L; enters high-Z when OE = H - isolates downstream circuitry |
| 5 (VCC) | Positive supply | Supplies core logic and output drivers; tolerant of 0.8–3.6 V; powers Ioff circuitry |
Key Features
| Feature | Design Value |
|---|---|
| Input-disable capability | Allows A input to float safely when OE = H - eliminates need for external pull resistors in standby mode |
| Ioff partial power-down | Blocks current flow into/out of I/O pins when VCC = 0 V - protects powered subsystems during hot insertion |
| 3.6-V I/O tolerance | Permits 3.3-V signals on A or Y while VCC = 0.8–1.2 V - enables seamless voltage translation in multi-rail SoC interfaces |
| Low noise design | Overshoot/undershoot <10% of VCC - reduces EMI and eliminates need for series termination in short traces |
| NanoStar™ packaging | Dies-as-package construction achieves 0.80 mm × 0.80 mm footprint - saves >60% board area vs. SOT-23 |

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 |
|---|---|---|---|
| SN74LVC1G240DBVR | Higher ICC (10 µA typ), 1.65–5.5 V VCC range, no Ioff, no input hysteresis | Suitable for 5-V legacy systems but lacks partial power-down and noise immunity for battery operation | Choose only if 5-V compatibility is required and Ioff/hysteresis are not needed. |
| NC7SZ240P5X | Smaller 1.2 mm × 1.6 mm SC70-5 package, 1.65–5.5 V VCC, no Ioff, 3.5 ns tpd at 3.3 V | Better speed for 3.3-V fixed-rail systems but incompatible with sub-1.2-V cores and unsafe for hot-swap | Select when layout space allows SC70 and system uses stable 3.3-V supply without partial power sequencing. |

FAQ
What is the minimum supply voltage for reliable operation of SN74AUP1G240?
The SN74AUP1G240 is fully specified from 0.8 V to 3.6 V. At 0.8 V, it maintains functional logic behavior with tpd ≤17.1 ns (CL = 5 pF), enabling direct interface with sub-1-V microcontrollers and energy-harvesting PMUs. Below 0.8 V, timing and drive strength are not guaranteed per datasheet specifications.
Does SN74AUP1G240 support hot-plug or partial power-down scenarios?
Yes. SN74AUP1G240 incorporates Ioff circuitry that limits input/output leakage to ≤0.6 µA when VCC = 0 V, preventing back-current damage during hot-insertion or staggered power sequencing. This makes SN74AUP1G240 suitable for modular systems where boards may be powered independently.
Can the A input of SN74AUP1G240 be left unconnected?
Yes - but only when OE is held HIGH. The input-disable feature allows the A pin to float safely in 3-state mode. When OE = LOW, A must be driven to a valid logic level (VCC or GND) to ensure predictable output behavior and avoid increased ICC.
What is the recommended pull-up resistor value for OE on SN74AUP1G240?
To ensure high-impedance state during power-up/power-down, OE should be tied to VCC via a pull-up resistor. Minimum value is determined by the driver's sink capability: for typical 1.1-mA sink at 1.1 V, R ≤ 1 kΩ is safe; 10 kΩ is common for low-current systems. Avoid values >100 kΩ to prevent slow enable/disable transitions.
How does SN74AUP1G240 handle slow or noisy input signals on the A pin?
SN74AUP1G240 includes built-in input hysteresis (~100 mV), which provides noise margin against ringing and slow edges on the A input. This eliminates the need for external Schmitt-trigger buffers in most industrial and medical applications where switch debouncing or long trace routing introduces signal degradation.
