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 enable timing (tdis ≤ 4.1 ns at 3.3 V), input hysteresis for noise immunity, 3.6-V I/O tolerance for mixed-voltage interfacing, and NanoStar™ SOT-23 package compatibility with space-constrained PCB layouts.
Technical Context
The SN74AUP1G240 implements a single inverting buffer with active-low output-enable (OE) control, performing Y = A̅. Its CMOS inputs feature built-in hysteresis (≈100 mV typical) to tolerate slow transitions and reject switching noise, while balanced push-pull outputs support symmetrical sourcing/sinking up to ±20 mA.
It integrates Ioff circuitry that places all I/O pins in high-impedance state when VCC = 0 V, preventing back-current damage during hot insertion or partial power-down. The device is fully characterized for operation from –40°C to +85°C and meets JESD 78 Class II latch-up (>100 mA) and JESD 22 HBM (2000 V) / CDM (1000 V) ESD standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface between 0.8-V microcontrollers and 3.3-V peripherals without level shifters. |
| tpd (max) | 4.7 ns at 3.3 V - ensures sub-5-ns signal inversion for high-speed point-to-point data paths. |
| 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 - guarantees safe isolation during system power sequencing. |
| Cpd | 4.2 pF at 3.3 V - minimizes dynamic power in high-frequency clock distribution or data strobe lines. |
| Input Hysteresis | ≈100 mV - rejects >100-mV noise spikes on slow-rising control signals (e.g., reset, enable lines). |
| 3.6-V I/O Tolerance | Supports 3.3-V inputs even when VCC = 0.8 V - simplifies mixed-voltage board design without external clamping. |
Pinout & Package
SN74AUP1G240DBVT uses the 5-pin SOT-23 (DBV) package, measuring 1.60 mm × 2.90 mm, with exposed pad not present. Pin 1 is OE (active-low output enable), Pin 2 is A (inverting input), Pin 3 is GND, Pin 4 is Y (inverted output), and Pin 5 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low output enable | Drives Y to high-impedance when high; requires pullup to VCC for power-up safety. |
| 2 (A) | Inverting logic input | Accepts 0.8–3.6 V signals; hysteresis prevents chatter on noisy or slow edges. |
| 3 (GND) | Ground reference | Common return path for logic and Ioff leakage current; must be low-impedance. |
| 4 (Y) | Inverted 3-state output | Sources/sinks ±20 mA; floats to high-Z when OE = high; 3.6-V tolerant. |
| 5 (VCC) | Positive supply | Supplies core logic and output drivers; powers Ioff circuitry for safe shutdown. |
Key Features
| Feature | Design Value |
|---|---|
| Input-disable capability | Allows A input to float safely when OE = high - eliminates need for external pull resistors in standby mode. |
| Ioff partial power-down | Prevents back-current flow into powered-down sections - critical for hot-swap I/O expansion cards. |
| Low noise overshoot/undershoot | <10% of VCC - reduces EMI and eliminates need for series termination in short traces. |
| NanoStar™ packaging | Dies-as-package construction achieves 1.6 × 2.9 mm footprint - saves >40% board area vs. standard SOT-23. |
| Wide VCC hysteresis margin | Operates reliably down to 0.8 V while maintaining 100-mV noise immunity - ideal for brown-out detection circuits. |

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), wider VCC range (1.65–5.5 V), no Ioff, no input hysteresis | Better suited for 5-V legacy interfaces but lacks partial power-down safety for hot-plug systems | Select when interfacing to 5-V logic and thermal budget allows higher static power |
| NC7SZ240P5X | Lower drive (±8 mA), no Ioff, 1.65–5.5 V VCC, smaller SC70-5 package (1.25 × 2.00 mm) | Optimized for cost-sensitive consumer devices where Ioff and ultra-low ICC are not required | Select for space-constrained designs needing lowest footprint, not lowest power or hot-swap robustness |
Compared with SN74LVC1G240DBVR and NC7SZ240P5X, SN74AUP1G240DBVT uniquely combines sub-1-µA ICC, Ioff-enabled safe power sequencing, and input hysteresis - making it the only choice for battery-critical, hot-pluggable, or noise-prone embedded systems requiring guaranteed 3-state behavior at 0.8 V.

FAQ
What is the maximum propagation delay of SN74AUP1G240DBVT at 3.3 V?
The maximum propagation delay (tpd) of SN74AUP1G240DBVT is 4.7 ns at VCC = 3.3 V ± 0.3 V, measured under –40°C to +85°C ambient conditions with CL = 5 pF. This value is specified in the Switching Characteristics table (Section 6.6) of the official TI datasheet SCES627D. SN74AUP1G240DBVT maintains this performance across its full operating temperature range, enabling reliable timing in high-speed point-to-point links.
Does SN74AUP1G240DBVT support partial power-down operation?
Yes, SN74AUP1G240DBVT fully supports partial power-down via its integrated Ioff circuitry. When VCC = 0 V, all I/O pins enter a high-impedance state with leakage ≤0.6 µA over temperature, preventing back-current flow that could damage upstream or downstream components. This feature is explicitly documented in Section 8.3.4 and Electrical Characteristics (Section 6.5) of the SN74AUP1G240DBVT datasheet.
What is the input hysteresis value of SN74AUP1G240DBVT, and why does it matter?
SN74AUP1G240DBVT features built-in input hysteresis of approximately 100 mV, as confirmed by functional description (Section 8.3.2) and application notes in the datasheet. This hysteresis improves noise immunity on slow-rising control signals (e.g., reset, enable lines) by creating distinct VIH and VIL thresholds - preventing oscillation or false triggering in electrically noisy environments like motor-driven industrial equipment.
Can SN74AUP1G240DBVT accept 3.3-V inputs while operating at 0.8 V VCC?
Yes, SN74AUP1G240DBVT supports 3.6-V tolerant inputs, meaning it can safely accept 3.3-V logic signals even when VCC is as low as 0.8 V. This capability is explicitly stated in the Features section and verified in Absolute Maximum Ratings (Section 6.1), where VI max = 4.6 V. This eliminates external level-shifting components in mixed-voltage systems such as wearables interfacing 3.3-V sensors to 0.8-V processors.
What package type and dimensions does SN74AUP1G240DBVT use?
SN74AUP1G240DBVT uses the 5-pin SOT-23 (DBV) package, with nominal body dimensions of 1.60 mm × 2.90 mm. This information is confirmed in the Device Information table (page 2) and Mechanical Drawings section of the TI datasheet SCES627D. The DBV variant is distinct from DCK (SC70), DRY/DSF (SON), and YFP/YZP (DSBGA) variants - SN74AUP1G240DBVT is exclusively available in SOT-23.
