Product details
Overview
SN74AUP1G240 from Texas Instruments is a low-power single inverter with active-low 3-state output, designed for voltage-level translation and bus isolation in portable systems. 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), ultra-low input capacitance (1.5 pF), 3.6-V I/O tolerance, and SC70-5 package compatibility with space-constrained PCB layouts.
Technical Context
The SN74AUP1G240 implements a single inverting buffer with active-low output-enable control (OE), performing Y = A̅. Its CMOS inputs feature built-in hysteresis for noise immunity on slow transitions, and its balanced push-pull 3-state outputs support bidirectional signal routing without external pull-ups when disabled.
It integrates Ioff circuitry that forces all I/O into high-impedance during VCC ramp-up/down, preventing back-current damage. Input-disable functionality allows floating A input when OE is high, and over-voltage tolerant inputs accept signals up to 4.6 V regardless of VCC level.
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 timing-critical control paths in real-time embedded systems. |
| ICC (max) | 0.9 µA - reduces quiescent current by >90% vs. LVC family, extending battery life in always-on sensor nodes. |
| Ioff (max) | 0.6 µA at –40°C to +85°C - guarantees safe isolation during partial power-down in multi-rail systems. |
| Cpd | 4.2 pF typical at 3.3 V - minimizes dynamic switching power in high-frequency clock distribution or data bus applications. |
| CI | 1.5 pF typical - lowers capacitive loading on driving sources, preserving signal integrity in high-speed GPIO expansion. |
| VOH/VOL | VCC–0.1 V / 0.1 V at 20 µA - provides rail-to-rail logic swing compatible with 1.2-V, 1.8-V, and 3.3-V logic families. |
Pinout & Package
SN74AUP1G240DCKR uses the SC70-5 (SOT-353) package, measuring 1.25 mm × 2.00 mm with 0.65-mm lead pitch. This ultra-small outline supports high-density routing in wearables and compact IoT edge devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low output enable | Drives output Y to high-impedance when logic high; must be pulled up to VCC via external resistor during power sequencing. |
| 2 (A) | Inverter input | Accepts 0.8–3.6 V logic signals; supports floating state when OE = high per input-disable feature. |
| 3 (GND) | Ground reference | Primary return path for I/O and supply currents; requires low-inductance connection to minimize ground bounce. |
| 4 (Y) | Inverted 3-state output | Delivers A̅ when OE = low; enters Hi-Z when OE = high - enabling shared-bus arbitration and load isolation. |
| 5 (VCC) | Positive supply | Supplies core logic and output drivers; decoupling capacitor (0.1 µF) required within 2 mm for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Input hysteresis | Enables reliable switching with slow-rising/falling signals (e.g., mechanical switch debouncing) without external Schmitt triggers. |
| Ioff partial power-down | Prevents back-current flow into powered-down sections, allowing hot-swap capability in modular industrial controllers. |
| 3.6-V I/O tolerance | Permits interfacing with legacy 3.3-V peripherals while operating from 1.2-V or 1.8-V rails - eliminating discrete level translators. |
| NanoStar™ packaging | Die-as-package construction reduces parasitic inductance/capacitance, improving EMI performance in RF-sensitive medical telemetry designs. |
| Low noise (<10% overshoot) | Minimizes EMI emissions and crosstalk in mixed-signal PCBs housing analog sensors and digital logic. |

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 |
|---|---|---|---|
| SN74LVC1G04DCKR | Higher ICC (10 µA max), narrower VCC range (1.65–5.5 V), no Ioff or input-disable features. | Lacks partial power-down safety; unsuitable for mixed-rail hot-swap systems. | Choose only if operating strictly at ≥1.65 V and Ioff is not required. |
| NC7SZ04P5X | Lower drive strength, no 3.6-V I/O tolerance, no hysteresis, ICC = 1 µA max. | Not suitable for level translation between 0.8-V and 3.3-V domains. | Select when cost is primary constraint and full AUP-family benefits are unnecessary. |
Compared with SN74LVC1G04DCKR and NC7SZ04P5X, SN74AUP1G240DCKR uniquely combines sub-1-µA static power, 0.8–3.6-V operation, Ioff, and 3.6-V I/O tolerance - making it the only option qualified for battery-powered, multi-voltage, safety-critical edge nodes.

FAQ
What is the maximum propagation delay of SN74AUP1G240DCKR at 3.3 V?
The maximum propagation delay (tpd) of SN74AUP1G240DCKR is 4.7 ns at VCC = 3.3 V ± 0.3 V and TA = –40°C to +85°C, measured with CL = 5 pF. This value is guaranteed across the full industrial temperature range and ensures deterministic timing in real-time control applications where SN74AUP1G240DCKR serves as a critical signal path element.
Does SN74AUP1G240DCKR support partial power-down operation?
Yes, SN74AUP1G240DCKR fully supports partial power-down via its Ioff circuitry. When VCC = 0 V, all inputs and outputs enter a high-impedance state with leakage ≤0.6 µA over temperature. This feature prevents back-current damage during hot-swap or multi-rail sequencing - a capability explicitly verified in the SN74AUP1G240DCKR datasheet Section 8.3.4 and Electrical Characteristics table.
Can SN74AUP1G240DCKR interface between 0.8-V and 3.3-V logic domains?
Yes, SN74AUP1G240DCKR is explicitly designed for this purpose. Its 0.8–3.6-V VCC range and 3.6-V I/O tolerance allow it to accept 3.3-V inputs while powered from 0.8 V, and drive 3.3-V loads while powered from 1.2 V. The SN74AUP1G240DCKR datasheet confirms this in Sections 6.3 (Recommended Operating Conditions) and 8.3.5 (Over-Voltage Tolerant Inputs).
What is the input capacitance of SN74AUP1G240DCKR, and why does it matter?
SN74AUP1G240DCKR has a typical input capacitance (CI) of 1.5 pF. This low value minimizes capacitive loading on upstream drivers - preserving rise/fall times and reducing dynamic power in high-frequency GPIO or clock fanout applications. It is directly specified in the Electrical Characteristics table (Section 6.5) and critical for maintaining signal integrity in dense, high-speed PCB layouts using SN74AUP1G240DCKR.
How should the OE pin of SN74AUP1G240DCKR be handled during power-up?
The OE pin of SN74AUP1G240DCKR must be tied to VCC through a pullup resistor during power-up and power-down to ensure the output remains in high-impedance state. TI specifies this in Section 3 (Description) and Section 8.1 (Overview). The minimum resistor value depends on the driver's current-sinking capability - typically 10 kΩ suffices for most microcontroller-driven OE control in SN74AUP1G240DCKR implementations.
