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 IoT edge nodes.
For engineers reviewing the SN74AUP1G240 datasheet, SN74AUP1G240 pinout, SN74AUP1G240 application, or SN74AUP1G240 equivalent, key selection factors include its 5-pin DSBGA (YZP) package, active-low OE control, 3.6-V I/O tolerance, input hysteresis for noise immunity, and verified compatibility with 0.8–1.2 V core logic interfacing to 3.3 V peripherals.
Technical Context
The SN74AUP1G240 implements a single inverting buffer with active-low 3-state enable (OE), performing Y = A̅. Its CMOS input stage includes built-in hysteresis (≈100 mV typical) to tolerate slow-rising signals and reject switching noise - critical for direct connection to mechanical switches or low-speed microcontroller GPIOs.
It features Ioff circuitry that disables all I/Os when VCC = 0 V, preventing back-current flow during partial power-down sequences. The balanced push-pull output drives ±20 mA while maintaining <10% VCC overshoot/undershoot, and its 1.5 pF input capacitance minimizes loading on high-impedance sources.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 0.8 V to 3.6 V - enables direct interface between sub-1-V processors 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 latency budgets in sensor data paths. |
| 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 - guarantees safe isolation during hot-swap or multi-rail power sequencing. |
| Cpd | 4.2 pF typical at 3.3 V - reduces dynamic power consumption in high-frequency clock distribution or data strobe lines. |
| CI | 1.5 pF typical - preserves signal integrity when driving long PCB traces or capacitive touch interfaces. |
| VOH/VOL | VCC – 0.1 V / 0.1 V at 20 µA - provides rail-to-rail output swing compatible with downstream CMOS inputs. |
Pinout & Package
SN74AUP1G240YZPR uses a 5-pin DSBGA (YZP) package measuring 0.89 mm × 1.39 mm with bottom-side ball layout. Pin 1 (A) is the inverting input; Pin 2 (OE) is active-low output enable; Pin 3 (GND) is ground; Pin 4 (Y) is the inverted 3-state output; Pin 5 (VCC) is the supply rail. No internal connection (N.C.) is present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Inverting input | Accepts logic levels from 0.8 V to 3.6 V; floats safely when OE = high due to input-disable feature. |
| OE | Active-low output enable | Pulls output Y to high-impedance when high; requires external pullup to VCC for power-up safety. |
| GND | Ground reference | Return path for all internal logic and output current; must be low-inductance for EMI control. |
| Y | Inverted 3-state output | Drives complementary logic; sinks/sources up to ±20 mA; enters Hi-Z when OE = high. |
| VCC | Positive supply | Power rail for core logic and output drivers; tolerant of 3.6-V transients per I/O specification. |
Key Features
| Feature | Design Value |
|---|---|
| Input hysteresis | Enables reliable switching with slow or noisy inputs (e.g., mechanical buttons), eliminating need for external Schmitt triggers. |
| Ioff partial power-down | Prevents back-current damage when VCC is off but I/Os remain biased - essential for modular system hot-plug compliance. |
| 3.6-V I/O tolerance | Allows direct connection to 3.3-V buses while powered from 1.2-V or 1.8-V rails, simplifying mixed-voltage board design. |
| Low Cpd (4.2 pF) | Reduces dynamic power by >50% vs. LVC-family equivalents at 10 MHz, extending runtime in portable diagnostics devices. |
| NanoStar™ DSBGA packaging | 0.89 mm × 1.39 mm footprint saves >60% board area vs. SOT-23, enabling ultra-compact wearables and implantables. |

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 tpd range (5.5 ns max at 3.3 V), no Ioff support | Lacks partial power-down capability; unsuitable for hot-swap or multi-rail systems requiring back-current blocking | Choose for cost-sensitive non-battery applications where Ioff is not required and 5.5-ns latency is acceptable |
| NC7SZ240P5X | Smaller 5-pin SC70 package (1.25 mm × 2.00 mm), higher Cpd (6.5 pF), no input hysteresis | Less noise immunity on slow inputs; larger footprint than YZP DSBGA; higher dynamic power at 10+ MHz | Choose when SC70 is preferred for reworkability, and hysteresis is unnecessary for clean digital sources |

FAQ
What is the function of SN74AUP1G240YZPR?
The SN74AUP1G240YZPR is a single inverter with active-low 3-state output enable (OE). It performs the Boolean function Y = A̅ and places the output Y in high-impedance state when OE is high. Its design supports voltage translation, bus isolation, and low-power signal conditioning in portable electronics.
Does SN74AUP1G240YZPR support partial power-down operation?
Yes, SN74AUP1G240YZPR includes Ioff circuitry that disables all inputs and outputs when VCC = 0 V, limiting leakage current to ≤0.6 µA over temperature. This prevents back-current flow during partial power-down sequences - a critical requirement for hot-pluggable modules and multi-rail systems.
What is the recommended pullup resistor value for OE on SN74AUP1G240YZPR?
To ensure high-impedance state during power-up/power-down, OE must be tied to VCC via a pullup resistor. The minimum value is determined by the driver's current-sinking capability; TI recommends ≥10 kΩ for standard operation, with lower values (e.g., 4.7 kΩ) acceptable if faster enable timing is needed and sink current remains within spec.
Can SN74AUP1G240YZPR interface between 1.2-V and 3.3-V logic domains?
Yes, SN74AUP1G240YZPR supports 0.8–3.6 V VCC operation and has 3.6-V tolerant I/Os. When powered from 1.2 V, it accepts 3.3-V inputs safely and outputs 0–1.2 V logic levels - enabling bidirectional level translation without external components in mixed-voltage designs.
Is input hysteresis present on SN74AUP1G240YZPR, and what benefit does it provide?
Yes, SN74AUP1G240YZPR includes built-in input hysteresis (~100 mV typical), which improves noise immunity and allows reliable switching with slow-rising signals - such as those from mechanical switches or RC-filtered microcontroller outputs - without requiring external Schmitt-trigger buffers.
