Product details
Overview
74LVC2G241DC-Q100 from Nexperia is a dual non-inverting buffer/line driver with 3-state outputs, designed for automotive signal routing and level translation between 3.3 V and 5 V logic domains. It features Schmitt-trigger inputs for noise immunity, ±24 mA output drive at 3.0 V, IOFF partial power-down protection, and AEC-Q100 Grade 1 qualification (−40 °C to +125 °C). It is used in body control modules and infotainment interface circuits requiring bidirectional voltage compatibility.
For engineers reviewing the 74LVC2G241DC-Q100 datasheet, 74LVC2G241DC-Q100 pinout, 74LVC2G241DC-Q100 application, or 74LVC2G241DC-Q100 equivalent, key selection criteria include 3-state enable polarity asymmetry (1OE active LOW, 2OE active HIGH), 1.65 V to 5.5 V supply range, 5 V-tolerant I/O, IOFF backflow prevention, and VSSOP8 (SOT765-1) package footprint compatibility.
Technical Context
This device implements two independent non-inverting buffers, each with asymmetric 3-state control: Output 1Y is disabled by HIGH on 1OE (pin 1), while output 2Y is disabled by HIGH on 2OE (pin 7). Schmitt-trigger inputs accept slow-rising signals and tolerate input voltages up to 5 V regardless of VCC, enabling mixed-voltage interfacing without external level shifters.
The IOFF circuit actively disables outputs when VCC = 0 V, blocking damaging backflow current during hot insertion or partial power-down. Static and dynamic characteristics are fully specified across −40 °C to +125 °C, with propagation delays as low as 0.5 ns at 5 V and enable/disable times under 4.6 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports single-rail operation across 1.8 V, 2.5 V, 3.3 V, and 5 V systems |
| Input Voltage Tolerance | Up to 5.5 V - allows direct connection to 5 V TTL or CMOS outputs without clamping diodes |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 Ω transmission lines or multiple CMOS loads |
| Propagation Delay | 0.5 ns (min) to 4.6 ns (max) at VCC = 4.5–5.5 V - enables high-speed bus buffering in automotive serial links |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - prevents >100 μA backfeed into powered-down subsystems |
| Operating Temperature | −40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for under-hood and cabin electronics |
| ESD Protection | HBM >2000 V, CDM >1000 V - exceeds automotive ESD robustness requirements per ISO 10605 |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; pin 1 indicator located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-LOW output enable for buffer 1 - drives 1Y to high-impedance when HIGH |
| 2 | VCC | Positive supply rail - powers both buffers and internal logic; decoupling required near pin |
| 3 | 1A | Data input for buffer 1 - Schmitt-triggered, 5 V tolerant, referenced to GND |
| 4 | 2OE | Active-HIGH output enable for buffer 2 - drives 2Y to high-impedance when HIGH |
| 5 | 2Y | Inverted-output terminal for buffer 2 - non-inverting output, 3-state capable |
| 6 | 1Y | Non-inverting output for buffer 1 - driven only when 1OE = LOW; high-Z otherwise |
| 7 | GND | Ground reference - return path for all currents; must be low-inductance connection |
| 8 | 2A | Data input for buffer 2 - identical electrical behavior to 1A; independent signal path |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetric 3-state control | 1OE active LOW and 2OE active HIGH allow independent, polarity-matched enable signaling in multi-master buses |
| IOFF partial power-down protection | Prevents reverse current flow when VCC = 0 V, enabling safe hot-swap in modular automotive ECUs |
| Schmitt-trigger inputs | Provides >0.3 V hysteresis, rejecting noise on slow-rising sensor or switch signals in harsh vehicle environments |
| 5 V-tolerant I/O | Accepts 0–5.5 V inputs and drives 5 V logic levels even at VCC = 1.65 V, eliminating external translators |
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from −40 °C to +125 °C ambient, meeting automotive engine bay requirements |

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 |
|---|---|---|---|
| SN74LVC2G241DBVR | Industrial grade (−40 °C to +85 °C); no AEC-Q100 qualification; identical pinout and electrical specs | Not suitable for automotive under-hood or safety-critical modules requiring Grade 1 temperature range | Select only for cost-sensitive non-automotive designs where extended temperature and qualification are unnecessary |
| 74LVC2G125DC-Q100 | Same package and AEC-Q100 Grade 1 rating, but features two independent 3-state buffers with active-HIGH enables on both channels | Lacks asymmetric enable polarity; cannot replace 74LVC2G241DC-Q100 in designs requiring one active-LOW and one active-HIGH enable | Choose when both enables must be active-HIGH; verify enable logic compatibility before substitution |
Compared with SN74LVC2G241DBVR and 74LVC2G125DC-Q100, the 74LVC2G241DC-Q100 uniquely combines automotive qualification with asymmetric enable polarity-enabling precise bus arbitration control in mixed-voltage automotive networks where one channel must respond to LOW-enable logic and the other to HIGH-enable logic.

FAQ
What is the function of the asymmetric enable inputs (1OE active LOW, 2OE active HIGH)?
The asymmetric enable configuration allows independent control of two buffered signals using complementary logic polarities-enabling direct interface with legacy microcontrollers that provide one enable signal as active LOW and another as active HIGH. This eliminates external inverters in bus arbitration or multiplexing circuits, reducing BOM count and PCB area while preserving timing integrity.
Can 74LVC2G241DC-Q100 operate with VCC = 1.8 V while interfacing with 5 V inputs?
Yes. The device accepts input voltages up to 5.5 V regardless of VCC level, including at 1.8 V supply. Input thresholds scale with VCC (e.g., VIH ≈ 0.65 × VCC at 1.65–1.95 V), and Schmitt-trigger hysteresis ensures clean switching. Outputs swing rail-to-rail but are limited to VCC, so 5 V logic levels must be received-not generated-at 1.8 V operation.
How does IOFF protect the device during partial power-down?
When VCC = 0 V, the IOFF circuit disables both outputs and isolates input pins, limiting backflow current to ±2 μA even if 5 V signals are applied to inputs or outputs. This prevents damage to unpowered ICs in modular systems and avoids unintended activation of downstream circuitry, satisfying ISO 11898-2 and automotive functional safety requirements for power sequencing.
Is the VSSOP8 (SOT765-1) package compatible with standard TSSOP8 (SOT505-2) footprints?
No. The VSSOP8 package has 2.3 mm body width and 0.5 mm lead pitch, while TSSOP8 measures 3.0 mm body width with same pitch. Though pin numbering and functions match, mechanical incompatibility requires separate PCB land patterns. Thermal resistance differs (4.9 mW/K derating above 99 °C vs. 4.6 mW/K above 96 °C), affecting high-power layout decisions.
