Product details
Overview
74AUP2G241DC,125 from Nexperia is a dual non-inverting 3-state buffer/line driver in VSSOP8 (SOT765-1) package, operating from 0.8 V to 3.6 V supply. It features Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and input-disable functionality. Each channel has independent output enable control (1OE active LOW, 2OE active HIGH), enabling flexible bus isolation in low-power portable and industrial interface applications.
For engineers reviewing the 74AUP2G241DC,125 datasheet, 74AUP2G241DC,125 pinout, 74AUP2G241DC,125 application, or 74AUP2G241DC,125 equivalent, key selection criteria include its ultra-low ICC (≤1.4 μA max), wide VCC range, guaranteed operation up to +125 °C, and compatibility with mixed-voltage I/O systems where 3.6 V-tolerant inputs interface with sub-1.2 V logic domains.
Technical Context
This device implements two independent non-inverting buffers with asymmetric 3-state control logic: 1Y is disabled by HIGH on 1OE, while 2Y is disabled by LOW on 2OE. Schmitt-trigger inputs ensure robust signal integrity across slow-rising signals and full VCC range (0.8–3.6 V), eliminating external hysteresis components.
The IOFF circuit actively blocks current flow when VCC = 0 V, preventing backfeed during partial power-down. Input-disable behavior-where 1A is electrically isolated when 1OE = HIGH and 2A when 2OE = LOW-reduces dynamic leakage and enables floating-bus operation without pull resistors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage (VCC) | 0.8 V to 3.6 V - supports single-supply operation across 1.0 V, 1.2 V, 1.8 V, 2.5 V, and 3.3 V logic families. |
| Max ICC (static) | 1.4 μA at +125 °C - enables battery-powered systems with multi-year standby life. |
| Input voltage tolerance | Up to 3.6 V - allows interfacing with higher-voltage peripherals while powered from lower VCC. |
| Propagation delay (tpd) | 1.4 ns (min) to 4.4 ns (max) at VCC = 3.0–3.6 V, CL = 5 pF - ensures timing-critical signal buffering with minimal latency. |
| Operating temperature | -40 °C to +125 °C - qualified for automotive under-hood, industrial motor control, and harsh-environment IoT nodes. |
| IOFF leakage | ±0.75 μA max at VCC = 0 V - prevents damaging back-current during hot-swap or staged power sequencing. |
| ESD rating | HBM >5000 V, CDM >1000 V - meets IEC 61000-4-2 Level 4 for system-level robustness in field-deployed equipment. |
Pinout & Package
VSSOP8 package (SOT765-1), plastic very thin shrink small outline, 8 leads, body width 2.3 mm, pin 1 indicator at lower-left corner below marking code "p41".
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-LOW output enable for Channel 1 - drives 1Y to high-impedance when HIGH. |
| 2 | VCC | Positive supply rail - powers internal logic and output drivers; decoupling required near pin. |
| 3 | 1A | Data input for Channel 1 - Schmitt-triggered, 3.6 V tolerant, disabled when 1OE = HIGH. |
| 4 | 2OE | Active-HIGH output enable for Channel 2 - drives 2Y to high-impedance when LOW. |
| 5 | 2Y | Data output for Channel 2 - non-inverting, 3-state, capable of sourcing/sinking ±20 mA. |
| 6 | 1Y | Data output for Channel 1 - non-inverting, 3-state, compatible with 5 pF to 30 pF load capacitance. |
| 7 | GND | Ground reference - must be low-impedance return path for both logic and output current. |
| 8 | 2A | Data input for Channel 2 - Schmitt-triggered, 3.6 V tolerant, disabled when 2OE = LOW. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range | 0.8 V to 3.6 V - eliminates level shifters in multi-rail SoC interfaces and battery-voltage-tracking systems. |
| Asymmetric OE logic | 1OE active LOW / 2OE active HIGH - enables simultaneous enable/disable coordination with complementary control signals in bus arbitration logic. |
| Input-disable function | 1A disabled when 1OE = HIGH; 2A disabled when 2OE = LOW - reduces input leakage and eliminates need for external pull-ups/downs on unused channels. |
| IOFF protection | Blocks current flow when VCC = 0 V - ensures safe hot-plug operation and prevents backfeed into powered subsystems during partial shutdown. |
| Schmitt-trigger inputs | Hysteresis ≥0.3 V typical at VCC = 3.3 V - rejects noise on long traces or unshielded cables without external RC filtering. |
Applications
| Industrial Sensor Interface | Low-Power Wearable Data Bus |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC2G241GW,125 | Higher ICC (max 10 μA), narrower VCC range (1.65–5.5 V), no IOFF or input-disable | Not suitable for partial power-down or sub-1.65 V systems; lacks Schmitt-trigger noise immunity | Select only if operating strictly above 1.65 V and IOFF is unnecessary |
| SN74AUP2G241DCKR | Identical electrical specs but in SC70-6 package (6-pin); missing 2OE pin - single-enable only | Cannot support independent dual-channel control; requires external logic for asymmetric OE | Use only when both outputs share the same enable signal and space constraints favor SC70 |

FAQ
What is the maximum capacitive load this device can drive reliably?
The 74AUP2G241DC,125 is characterized for loads up to 30 pF across all VCC conditions (0.8–3.6 V). Propagation delay increases predictably with load: tpd = 4.4 ns max at 30 pF, VCC = 3.3 V, CL = 30 pF. For loads >30 pF, output rise/fall times degrade beyond specification, risking setup/hold violations in synchronous systems.
Can 1OE and 2OE be tied together for synchronized control?
No - 1OE is active LOW while 2OE is active HIGH, so tying them directly causes conflicting logic states. To synchronize both outputs, invert one enable signal externally (e.g., use a 74AUP1G04) or route complementary control signals. The asymmetric design intentionally supports independent bus arbitration, not forced synchronization.
Does this part support hot insertion when VCC is unpowered?
Yes - the IOFF circuitry actively disables outputs and blocks current flow when VCC = 0 V, limiting backfeed current to ±0.75 μA max. This meets JEDEC JESD78 Class II latch-up immunity and enables safe hot-plug operation in modular backplane or docking station applications.
How does the input-disable feature affect signal integrity on unused inputs?
When 1OE = HIGH or 2OE = LOW, the corresponding input (1A or 2A) is electrically disconnected from internal circuitry, reducing input leakage to ±0.1 μA and eliminating switching noise coupling. This prevents floating-input oscillation and removes need for external termination resistors, simplifying PCB layout in multi-channel systems.
