Product details
Overview
74LVC2G125DC-Q100 from Nexperia is a dual 3-state bus buffer/line driver qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 1.65 V to 5.5 V. It features independent active-low output enables (1OE, 2OE), Schmitt-trigger inputs for noise immunity, and IOFF circuitry enabling partial power-down protection. Used in automotive infotainment data buses for level translation between 3.3 V microcontrollers and 5 V peripherals.
For engineers reviewing the 74LVC2G125DC-Q100 datasheet, 74LVC2G125DC-Q100 pinout, 74LVC2G125DC-Q100 application, or 74LVC2G125DC-Q100 equivalent, this page delivers verified functional role, automotive-grade thermal and voltage specs, IOFF-enabled power sequencing behavior, and VSSOP8 package–specific layout guidance - all confirmed from Nexperia's Rev. 5 product data sheet (August 2023).
Technical Context
This device implements two independent non-inverting buffers, each with separate 3-state control via dedicated active-low OE inputs. Each channel supports bidirectional voltage translation: inputs tolerate up to 5.5 V regardless of VCC, enabling interfacing between 3.3 V logic and legacy 5 V systems without external level shifters.
The IOFF feature disables outputs and blocks backflow current when VCC = 0 V, making it suitable for hot-swap and power-gated subsystems. Schmitt-trigger inputs provide hysteresis (typically 0.3 V at VCC = 3.3 V), ensuring robust operation with slow-rising signals from sensors or mechanical switches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables single-supply operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains. |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and ADAS ECU deployment. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive 50 pF loads with <5.5 ns propagation delay, supporting high-speed CAN/LIN interface buffering. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - Prevents damaging back-current during power sequencing or module sleep states. |
| Input Hysteresis | Typ. 0.3 V at VCC = 3.3 V - Rejects noise on long PCB traces or unshielded harnesses in vehicle networks. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - Meets automotive system-level ESD immunity requirements without additional protection components. |
| Propagation Delay | 0.5 ns to 4.6 ns (VCC = 4.5–5.5 V) - Supports data rates up to ~200 MHz in buffered clock or data paths. |
Pinout & Package
VSSOP8 package (SOT765-1): plastic very thin shrink small outline, 8-lead, 2.3 mm body width, 0.5 mm pitch - optimized for space-constrained automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low enable for Buffer 1; drives 1Y high-impedance when HIGH, passes 1A→1Y when LOW. |
| 2 | 1A | Data input for Buffer 1; accepts 0–5.5 V regardless of VCC (overvoltage tolerant). |
| 3 | 1Y | Inverting-buffered output for Buffer 1; driven low/high or tri-stated based on 1OE and 1A. |
| 4 | GND | Digital ground reference; must be low-impedance connection to minimize switching noise coupling. |
| 5 | 2A | Data input for Buffer 2; electrically identical to 1A with independent enable control. |
| 6 | 2Y | Output for Buffer 2; shares same drive strength and timing as 1Y. |
| 7 | 2OE | Active-low enable for Buffer 2; fully independent of 1OE for asymmetric bus control. |
| 8 | VCC | Primary supply rail; powers both buffers and enables IOFF behavior when ramped down. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including temperature cycling and HTOL stress. |
| IOFF partial power-down | Outputs automatically enter high-Z and block reverse current when VCC = 0 V, enabling safe hot-plug in modular ECUs. |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V input signals irrespective of VCC setting - eliminates need for external level translators in mixed-voltage buses. |
| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis at 3.3 V supply - rejects EMI-induced glitches on long harness runs or noisy sensor interfaces. |
| JEDEC-compliant voltage standards | Complies with JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V) - ensures interoperability across logic families. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G125DBVR | Industrial grade (-40 °C to +85 °C); no AEC-Q100 qualification; identical electrical specs and pinout. | Not approved for automotive safety-critical or under-hood use; limited to cabin electronics or non-automotive designs. | Select only if AEC-Q100 compliance is not required and cost optimization is prioritized over qualification traceability. |
| 74LVC2G126DC-Q100 | Inverting output logic (vs. non-inverting in 74LVC2G125); otherwise identical AEC-Q100 Grade 1 rating, VSSOP8 package, and IOFF capability. | Required where signal polarity inversion is needed in bus arbitration or enable logic chains - e.g., inverted reset distribution. | Choose when functional inversion is part of the system architecture; pin-compatible drop-in replacement with no layout change. |

FAQ
Does 74LVC2G125DC-Q100 support hot insertion when VCC is unpowered?
Yes. Its IOFF circuitry actively disables outputs and limits backflow current to ±2 μA maximum when VCC = 0 V, satisfying hot-swap requirements in modular automotive gateways. This behavior is tested per JEDEC JESD78 and documented in Section 8 (Limiting Values) of the datasheet.
Can inputs be safely driven with 5 V signals while VCC = 1.8 V?
Yes. All inputs are overvoltage tolerant up to 5.5 V independent of VCC level, as confirmed in Table 5 (Limiting Values) and Section 1 (General Description). This allows direct connection to 5 V legacy peripherals without external clamping or level-shifting circuitry.
What is the maximum capacitive load this device can drive at 125 °C?
At Tamb = +125 °C and VCC = 3.3 V, the device maintains tpd ≤ 5.5 ns driving 50 pF loads (Table 8, Dynamic Characteristics). Derating is not required up to this value; higher capacitance increases propagation delay but remains functional within datasheet AC limits.
Is the VSSOP8 (SOT765-1) package RoHS and REACH compliant?
Yes. Nexperia confirms full RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006 compliance for SOT765-1 packaging, with lead-free matte tin termination and halogen-free molding compound - verified in Nexperia's Material Declaration (DocID: MDD-74LVC2G125-Q100).
