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 and battery-powered systems. It operates across 0.8 V to 3.6 V, delivers 4.7 ns max propagation delay at 3.3 V, supports Ioff partial power-down, and features 1.5 pF input capacitance - enabling use in point-to-point signal routing for 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 ultra-low ICC (0.9 µA max), 3.6-V I/O tolerance for mixed-voltage interfacing, active-low OE control, and SC70-5 package compatibility with space-constrained PCB layouts.
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 Ioff circuitry ensures high-impedance inputs/outputs during power-down, preventing back-current flow into powered-down subsystems - critical for hot-swap and partial-power-down architectures.
It uses standard CMOS inputs with built-in hysteresis for noise immunity on slow transitions, and balanced push-pull outputs capable of ±20 mA drive. Input-disable functionality allows floating A input when OE is high, eliminating need for external pull resistors in tri-state idle mode.
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 - supports >100 MHz signal routing in low-latency sensor interfaces. |
| ICC Max | 0.9 µA - extends battery life in always-on wearable health monitors by minimizing quiescent drain. |
| Ioff Max | 0.6 µA at –40°C to +85°C - guarantees safe isolation during partial power-down in multi-rail industrial controllers. |
| CI Typ | 1.5 pF - reduces capacitive loading on high-speed clock or data lines in compact IoT edge nodes. |
| IO Max | ±20 mA - drives LED indicators or small capacitive loads directly without external buffers. |
| Cpd Typ | 4.2 pF at 3.3 V - lowers dynamic power consumption in burst-mode communication links. |
Pinout & Package
SN74AUP1G240DCKT is packaged in a 5-pin SC70 (DCK) package measuring 1.25 mm × 2.00 mm, optimized for high-density portable PCBs.
| 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 sequencing. |
| 2 (A) | Inverter input | Accepts 0.8–3.6 V logic signals; supports floating when OE = H due to input-disable feature. |
| 3 (GND) | Ground reference | Common return path for all internal logic and I/O; requires low-inductance connection to minimize ground bounce. |
| 4 (Y) | Inverted 3-state output | Provides true inverted logic (Y = A) when OE = L; enters high-Z when OE = H - enables bus sharing. |
| 5 (VCC) | Positive supply | Supplies core logic and I/O; tolerant of 3.6-V transients while operating down to 0.8 V - supports mixed-voltage domains. |
Key Features
| Feature | Design Value |
|---|---|
| Input hysteresis | Enables reliable switching with slow or noisy input edges (e.g., mechanical switch debouncing without external RC). |
| Ioff partial power-down | Prevents current backflow from live buses into unpowered sections - essential for modular industrial PLC backplanes. |
| 3.6-V I/O tolerance | Allows 3.3-V peripherals to safely drive inputs while VCC = 1.2 V - simplifies voltage translation in multi-supply SoC interfaces. |
| NanoStar™ packaging | Die-as-package construction reduces parasitic inductance/capacitance - improves signal integrity in RF-adjacent digital routing. |
| Low noise overshoot/undershoot | <10% of VCC - eliminates need for series termination resistors in short trace applications like display timing control. |

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 |
|---|---|---|---|
| SN74LVC1G240DBVT | Higher ICC (10 µA typ), 1.65–5.5 V VCC range, no Ioff, 3.3-V only I/O tolerance | Not suitable for partial power-down; requires separate isolation for hot-swap | Choose for higher-speed (3.5 ns tpd) operation above 1.65 V where full power is always applied. |
| 74AHC1G04GW,125 | Non-3-state inverter; 2–5.5 V VCC; 3.3-V I/O tolerance; no Ioff or input-disable | Lacks bus isolation capability; cannot float inputs or enter high-Z state | Choose only when simple inversion is needed without enable control or power-gating requirements. |

FAQ
What is the function of the OE pin on the SN74AUP1G240DCKT?
The OE (output enable) pin on the SN74AUP1G240DCKT is an active-low control that places the Y output into high-impedance (3-state) when driven high. When OE is low, the device performs inversion (Y = A). To ensure high-Z during power-up/down, OE must be tied to VCC via a pullup resistor - minimum value determined by the driver's sink capability. This behavior is explicitly defined in the function table and pin description of the SN74AUP1G240DCKT datasheet.
Does the SN74AUP1G240DCKT support partial power-down operation?
Yes, the SN74AUP1G240DCKT fully supports partial power-down via its Ioff feature. When VCC = 0 V, both inputs and outputs enter a high-impedance state with leakage limited to 0.6 µA maximum over temperature. This prevents current backflow from live system buses into unpowered sections - a requirement validated in TI's Electrical Characteristics table and Detailed Description section for the SN74AUP1G240DCKT.
What is the maximum propagation delay of the SN74AUP1G240DCKT at 3.3 V?
The maximum propagation delay (tpd) of the SN74AUP1G240DCKT is 4.7 ns at VCC = 3.3 V ± 0.3 V, measured under recommended operating conditions with CL = 5 pF and TA = –40°C to +85°C. This value is specified in Table 6.6 (Switching Characteristics, CL = 5 pF) of the official SN74AUP1G240DCKT datasheet and reflects worst-case performance across voltage, temperature, and load.
Can the input A be left floating on the SN74AUP1G240DCKT?
Yes, the A input may be floated only when OE is high (output disabled), thanks to the input-disable feature explicitly documented for the SN74AUP1G240DCKT. When OE is low, A must be driven to a valid logic level (VCC or GND) to ensure correct operation. This behavior is confirmed in the "Features" and "Detailed Description" sections of the SN74AUP1G240DCKT datasheet.
What package type is used for the SN74AUP1G240DCKT?
The SN74AUP1G240DCKT uses the SC70-5 (DCK) package: a 5-pin surface-mount package with nominal body dimensions of 1.25 mm × 2.00 mm. This information is listed in the Device Information table and Mechanical, Packaging, and Orderable Information section of the SN74AUP1G240DCKT datasheet, and is distinct from the SOT-23 (DBV) and SON (DRY/DSF) variants.
