Product details
Overview
74LVC2G125DC-Q100 from Nexperia is an automotive-qualified dual 3-state bus buffer/line driver in VSSOP8 (SOT765-1) package, operating from 1.65 V to 5.5 V supply, supporting mixed-voltage translation between 3.3 V and 5 V systems, with ±24 mA output drive at 3.0 V and IOFF partial power-down protection. It serves as a level-shifting interface in automotive body control modules.
For engineers reviewing the 74LVC2G125DC-Q100 datasheet, 74LVC2G125DC-Q100 pinout, 74LVC2G125DC-Q100 application, or 74LVC2G125DC-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, -40 °C to +125 °C operation, Schmitt-trigger inputs for noise immunity, IOFF-enabled safe power-down, and VSSOP8 footprint compatibility with space-constrained automotive PCBs.
Technical Context
This device implements two independent non-inverting buffers, each with active-low 3-state enable (1OE, 2OE), enabling bidirectional bus isolation. Each channel features Schmitt-trigger inputs tolerant of slow rise/fall times and overvoltage-tolerant inputs up to 5.5 V regardless of VCC.
The IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down-critical for hot-swap and domain-isolation use cases. Propagation delay ranges from 0.5 ns (at 5 V) to 11.4 ns (at 1.65 V), with enable/disable times under 14.1 ns across full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct interfacing between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without external level shifters. |
| Operating Temperature | -40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood and powertrain applications. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive 50 Ω transmission lines or multiple CMOS/TTL loads in automotive networks. |
| Propagation Delay | 0.5 ns to 11.4 ns - Low-latency signal routing suitable for high-speed CAN/LIN subsystem interconnects and sensor data aggregation paths. |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - Prevents damaging back-current during system sleep or domain power sequencing. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - Allows 5 V inputs to be safely applied even when powered from 1.8 V or 2.5 V rails. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Meets automotive robustness requirements for assembly and field operation. |
Pinout & Package
VSSOP8 package (SOT765-1): plastic very thin shrink small outline, 8 leads, 2.3 mm body width, 0.5 mm lead pitch, pin 1 indicator at lower-left corner below marking "V25".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-low enable input for first buffer; asserts high-impedance state on 1Y when HIGH. |
| 2 | 1A | Data input for first buffer; passes through to 1Y when 1OE = LOW. |
| 3 | 1Y | Inverting-buffered output for first channel; driven LOW/HIGH or tri-stated based on 1A and 1OE. |
| 4 | GND | Ground reference (0 V) for all internal circuitry and I/O. |
| 5 | 2A | Data input for second buffer; passes through to 2Y when 2OE = LOW. |
| 6 | 2Y | Non-inverting-buffered output for second channel; driven LOW/HIGH or tri-stated based on 2A and 2OE. |
| 7 | 2OE | Active-low enable input for second buffer; asserts high-impedance state on 2Y when HIGH. |
| 8 | VCC | Positive supply rail (1.65 V–5.5 V); powers internal logic and output drivers. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including thermal cycling, humidity, and vibration stress testing. |
| Schmitt-trigger inputs | Provides hysteresis (typically 0.3–0.5 V) to reject noise on slow-rising signals from sensors or mechanical switches in vehicle cabins. |
| IOFF partial power-down | Automatically disables outputs and blocks reverse current when VCC = 0 V, enabling safe integration into multi-rail power architectures. |
| Overvoltage-tolerant inputs | Accepts 5.5 V inputs while VCC is as low as 1.65 V - eliminates need for external clamping diodes in mixed-supply designs. |
| JEDEC-compliant voltage standards | Meets 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) for interoperability across logic families. |

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 |
|---|---|---|---|
| SN74LVC2G125DBVR | Industrial-grade (not AEC-Q100 qualified); same pinout, identical electrical specs except -40 °C to +85 °C temp range and no IOFF characterization. | Not suitable for under-hood or powertrain locations requiring Grade 1 qualification; acceptable for cabin infotainment or HVAC control units. | Select only if automotive qualification is not required and cost sensitivity outweighs long-term reliability validation needs. |
| 74LVC2G126DC-Q100 | Inverting output logic (vs. non-inverting in 74LVC2G125DC-Q100); otherwise identical AEC-Q100 Grade 1 spec, VSSOP8 package, and IOFF capability. | Requires logic inversion in upstream/downstream firmware or hardware; used where signal polarity must be flipped (e.g., active-HIGH enable conversion). | Choose when system-level signal flow mandates inversion; verify timing impact of added gate delay in critical paths. |

FAQ
What is the maximum supply voltage rating for the 74LVC2G125DC-Q100?
The 74LVC2G125DC-Q100 has an absolute maximum supply voltage (VCC) of +6.5 V, but its recommended operating range is 1.65 V to 5.5 V. Operation above 5.5 V risks permanent damage and violates JEDEC compliance; sustained use at 6.5 V is prohibited per Absolute Maximum Ratings in the datasheet. The 74LVC2G125DC-Q100 must be operated within 1.65 V–5.5 V for guaranteed functionality and AEC-Q100 conformance.
Does the 74LVC2G125DC-Q100 support hot insertion or live board replacement?
Yes-the 74LVC2G125DC-Q100 supports hot insertion via its IOFF circuitry, which disables outputs and limits backflow current to ±2 μA when VCC = 0 V. This allows safe connection/disconnection while other system rails remain active. However, input pins must not exceed 5.5 V during insertion, and system-level ESD protection remains the designer's responsibility. The 74LVC2G125DC-Q100 is validated for this behavior per AEC-Q100 partial power-down test conditions.
Can the 74LVC2G125DC-Q100 translate 5 V inputs to a 1.8 V microcontroller interface?
Yes-the 74LVC2G125DC-Q100 accepts inputs up to 5.5 V regardless of VCC level, so with VCC = 1.8 V, it correctly interprets 5 V logic HIGH as valid VIH (≥0.65 × 1.8 V = 1.17 V). Its output VOH will be ~1.7 V (typical at 1.8 V), sufficient to meet most 1.8 V CMOS VIH thresholds. The 74LVC2G125DC-Q100 thus enables robust 5 V → 1.8 V unidirectional translation without external components.
What is the pin 1 identification method on the 74LVC2G125DC-Q100 VSSOP8 package?
Pin 1 on the 74LVC2G125DC-Q100 in VSSOP8 (SOT765-1) package is marked by a small indentation or beveled edge at the lower-left corner of the device body, located directly below the "V25" top-side marking. This physical index aligns with the standard JEDEC orientation for SOT765-1, where pins are numbered counter-clockwise starting from pin 1. The 74LVC2G125DC-Q100 datasheet confirms this in Section 4 (Marking) and Figure 7 (Package outline).
How does the Schmitt-trigger input improve noise immunity in automotive environments?
The Schmitt-trigger inputs on the 74LVC2G125DC-Q100 provide input hysteresis (~0.4 V typical), meaning the threshold for detecting a rising edge (VIH) is higher than for a falling edge (VIL). This prevents multiple toggles caused by slow or noisy signals-common from mechanical switches, potentiometers, or long harness runs in vehicles. The 74LVC2G125DC-Q100 thereby reduces firmware debouncing load and improves deterministic response in body control and sensor interface applications.
