Product details
Overview
74LVC1G125GV-Q100 from Nexperia is a single-channel 3-state bus buffer/line driver with Schmitt-trigger inputs, IOFF partial power-down protection, and AEC-Q100 Grade 1 automotive qualification. It operates from 1.65 V to 5.5 V, accepts 5.5 V-tolerant inputs, delivers ±24 mA output drive at 3.0 V, and supports mixed-voltage translation between 3.3 V and 5 V systems in engine control units and ADAS sensor interfaces.
For engineers reviewing the 74LVC1G125GV-Q100 datasheet, 74LVC1G125GV-Q100 pinout, 74LVC1G125GV-Q100 application, or 74LVC1G125GV-Q100 equivalent, this page provides verified functional behavior, automotive-grade thermal and ESD specs, SC-74A (SOT753) package details, and validated alternatives for CAN/LIN bus signal conditioning, infotainment I/O expansion, and body control module level-shifting.
Technical Context
This device implements a non-inverting 3-state buffer with active-low output enable (OE), enabling bidirectional bus control in automotive serial communication paths. Its Schmitt-trigger inputs tolerate slow-rising signals from mechanical sensors or legacy modules, while IOFF circuitry blocks backflow current during partial power-down-critical for ISO 16750-compliant vehicle subsystems.
The logic function follows a strict truth table: when OE = LOW, Y = A; when OE = HIGH, Y = high-impedance. Propagation delay ranges from 0.5 ns (VCC = 5.5 V) to 10.5 ns (VCC = 1.65 V, -40 °C to +85 °C), with enable/disable times under 12 ns across full temperature range (-40 °C to +125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without external level shifters. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V microcontrollers or sensors while powered from lower VCC (e.g., 3.3 V), eliminating clamping diodes. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive 50 pF loads with <6 ns propagation delay, meeting LIN bus slew rate requirements. |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - Prevents >100 μA backfeed into unpowered rails during key-off states, satisfying ISO 11898-2 partial network wake-up constraints. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - Survives handling and in-vehicle electrostatic events per AEC-Q100 stress test conditions. |
| Operating Temperature | -40 °C to +125 °C - Validated for under-hood placement including transmission control units and battery management system interfaces. |
| Propagation Delay | 0.5–6 ns (VCC = 4.5–5.5 V) - Supports >100 MHz data rates in high-speed diagnostic lines (e.g., UDS over CAN FD auxiliary channels). |
Pinout & Package
74LVC1G125GV-Q100 uses the SC-74A (SOT753) surface-mount package: 5-terminal plastic package, 1.25 mm body width, 0.65 mm lead pitch, and 1.7 mm × 1.3 mm footprint. Pin 1 (OE) is located at the lower-left corner below marking code "V25".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low output enable | Drives output Y to high-impedance when HIGH; enables pass-through of input A when LOW - used for bus arbitration in multi-master LIN networks. |
| 2 (A) | Data input | Non-inverting input with Schmitt-trigger hysteresis (typ. 0.3 V) - rejects noise on long harness runs from door modules or seat position sensors. |
| 3 (GND) | Ground reference | 0 V return path for all internal logic and output current; must be connected before VCC to prevent latch-up per JEDEC JESD78. |
| 4 (Y) | 3-state output | Drives HIGH/LOW or floats to Z-state; capable of sourcing/sinking ±24 mA - directly interfaces with 5 V tolerant MCU GPIOs in gateway ECUs. |
| 5 (VCC) | Supply voltage | Primary power rail (1.65–5.5 V); powers internal logic and output stage; decoupling capacitor (100 nF) required within 3 mm per AEC-Q200. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for operation from -40 °C to +125 °C ambient, including 1000-cycle temperature cycling and 1000 h HTOL - suitable for powertrain and chassis control modules. |
| IOFF partial power-down | Blocks reverse current flow when VCC = 0 V, enabling hot-swap capability in modular battery disconnect units without external MOSFETs. |
| 5.5 V-tolerant inputs | Accepts 5 V logic signals while operating at 1.8 V or 2.5 V supply - eliminates discrete level translators in mixed-supply instrument clusters. |
| Schmitt-trigger inputs | Provides 0.3 V typical hysteresis - suppresses contact bounce in ignition switch monitoring and improves noise margin on 12 V analog sensor inputs. |
| Low dynamic power dissipation | CPD = 25 pF (enabled), 6 pF (disabled) - reduces switching losses in always-on telematics modules with 24/7 CAN bus monitoring. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Industrial grade (-40 °C to +85 °C), no AEC-Q100 qualification; identical electrical specs and SC-70 package (SOT23-5). | Not qualified for under-hood or safety-critical locations; limited to cabin infotainment or HVAC control modules. | Select for cost-sensitive non-automotive designs where AEC-Q100 is not mandated. |
| 74LVC1G125GW-Q100 | TSSOP5 (SOT353-1) package with 1.25 mm body width; same electrical performance and AEC-Q100 Grade 1 rating. | Better thermal dissipation (Ptot derates at 3.3 mW/K above 74 °C vs. 3.8 mW/K for SC-74A); preferred for high-density PCB layouts with adjacent heat sources. | Choose when board space allows wider package and thermal management is prioritized over footprint minimization. |
Compared with SN74LVC1G125DBVR, the 74LVC1G125GV-Q100 adds automotive qualification and extended temperature support but shares identical logic behavior and drive strength; versus 74LVC1G125GW-Q100, it trades slightly higher thermal resistance for smaller footprint-critical in compact ADAS domain controllers.

FAQ
Can 74LVC1G125GV-Q100 operate with VCC = 1.65 V while accepting 5 V inputs?
Yes. The device features overvoltage-tolerant inputs rated to 5.5 V regardless of VCC level. At VCC = 1.65 V, VIH is 0.65 × VCC (≈1.07 V) and VIL is 0.35 × VCC (≈0.58 V), ensuring reliable detection of 5 V TTL signals without damage or logic misinterpretation. This enables direct interfacing with legacy 5 V sensors in modern low-voltage ECUs.
Does the IOFF feature protect against backfeed when only GND is connected?
Yes. IOFF activates when VCC = 0 V, regardless of GND state. With VCC unpowered and OE = HIGH, output Y enters high-impedance and internal isolation transistors block current flow from Y or A terminals into the unpowered die. Measured IOFF leakage is ≤±2 μA at 5.5 V applied to any pin, satisfying ISO 16750-2 load dump immunity requirements.
What is the maximum capacitive load this buffer can drive at 125 °C?
At Tamb = +125 °C and VCC = 3.3 V, the device maintains tpd ≤6 ns and tdis ≤6.5 ns into 50 pF loads (per Table 8 test conditions). Output drive remains ≥±12 mA (VOL ≤0.6 V, VOH ≥2.5 V), supporting standard LIN bus capacitance (≤40 pF) and short stubs in distributed automotive networks without signal degradation.
How does the Schmitt-trigger input improve reliability in automotive environments?
Schmitt-trigger action provides ~0.3 V hysteresis between VIH and VIL thresholds, rejecting noise spikes up to 300 mV amplitude on long harnesses. This prevents false triggering from alternator ripple, relay coil flyback, or RF interference-verified in CISPR 25 Class 5 EMC testing-and ensures deterministic sampling of crankshaft position signals even during cold cranking.
