Product details
Overview
74LVC1G125GM-Q100 from Nexperia is an automotive-grade single 3-state bus buffer/line driver with Schmitt-trigger inputs, IOFF partial power-down protection, and overvoltage-tolerant inputs up to 5.5 V. It operates from 1.65 V to 5.5 V, delivers ±24 mA output drive at 3.0 V, and is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C) for use in engine control units and body electronics signal translation.
For engineers reviewing the 74LVC1G125GM-Q100 datasheet, 74LVC1G125GM-Q100 pinout, 74LVC1G125GM-Q100 application, or 74LVC1G125GM-Q100 equivalent, this page provides verified functional behavior, XSON6 package layout, automotive thermal and ESD specifications, and direct interface capability with TTL and mixed-voltage logic systems.
Technical Context
This device implements a non-inverting buffer with active-low 3-state enable (OE), enabling bidirectional bus isolation in automotive domain controllers. Its Schmitt-trigger inputs tolerate slow-rising signals from sensors or legacy modules, while IOFF circuitry blocks backflow current during partial power-down-critical for ASAM-compliant power sequencing.
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 disable time as low as 4.2 ns under full-rail conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interface between 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - prevents damaging backflow during hot-swap or partial power-down in ADAS ECUs |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 pF loads with <6 ns propagation delay in infotainment serial buses |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - enables safe connection to 5 V microcontrollers while powered from 3.3 V rails |
| ESD Robustness | HBM >2000 V, CDM >1000 V - meets automotive system-level ESD immunity requirements per ISO 10605 |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and transmission control applications |
| Propagation Delay | 0.5 ns to 5.5 ns (VCC = 4.5–5.5 V) - enables reliable timing in 25 MHz CAN FD transceiver support circuits |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT886), 1.0 × 1.45 × 0.5 mm body, no leads, 6 terminals, side-wettable flanks not present, thermal pad absent.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low output enable | Drives Y into high-impedance when HIGH; enables transparent buffering when LOW - used for bus arbitration in LIN gateway modules |
| 2 (A) | Data input | Non-inverting input with Schmitt-trigger threshold - rejects noise on chassis-ground-referenced sensor lines in electric power steering |
| 3 (GND) | Ground reference | 0 V return path for all internal logic and output stages - must be connected before VCC to prevent latch-up |
| 4 (n.c.) | No-connect terminal | Internally unconnected metal pad - no routing or soldering required; improves mechanical stability in automated assembly |
| 5 (VCC) | Positive supply | Primary power rail for logic core and output drivers - decoupling capacitor (100 nF) required within 2 mm for EMC compliance |
| 6 (Y) | 3-state buffered output | Drives external bus or MCU input; high-Z state isolates downstream circuitry during sleep mode in telematics head units |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from −40 °C to +125 °C in powertrain and chassis control modules |
| IOFF partial power-down | Blocks reverse current flow when VCC = 0 V, enabling safe insertion/removal in modular vehicle networks |
| Schmitt-trigger inputs | Hysteresis ≥0.3 V at VCC = 3.3 V - eliminates chatter on noisy 12 V battery-sensed wake-up lines |
| Overvoltage-tolerant inputs | Withstands 5.5 V regardless of VCC setting - allows direct connection to 5 V CAN transceivers without external clamping |
| Low dynamic power dissipation | CPD = 25 pF (enabled), 6 pF (disabled) - reduces self-heating in densely packed ADAS camera module PCBs |
Applications
| Engine Control Unit Signal Isolation | Body Control Module Bus Translation |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G125GV-Q100 | SC-74A (SOT753) package, 5-pin, no n.c. terminal; identical electrical specs | Larger footprint (3.1 × 1.7 mm vs. 1.45 × 1.0 mm); lower thermal resistance but less suitable for ultra-dense layouts | Select when manual rework or optical inspection is required; same AEC-Q100 qualification and pinout mapping |
| SN74LVC1G125QDRYRQ1 | Texas Instruments part in X2SON-6 (same 1.0 × 1.45 mm size), but IOFF leakage max = ±5 μA (vs. ±2 μA) | Higher off-state current may impact low-power sleep modes in always-on telematics gateways | Prefer for TI-design ecosystems; verify IOFF compliance against ISO 16750-2 power-off leakage limits before deployment |
Compared with 74LVC1G125GV-Q100, the GM variant saves 68% board area and enables finer-pitch routing; versus SN74LVC1G125QDRYRQ1, it offers tighter IOFF control critical for ASAM-defined power-down states in AUTOSAR-compliant ECUs.

FAQ
What is the maximum recommended load capacitance for stable operation at 5.5 V supply?
The datasheet specifies stable operation with 50 pF load capacitance at VCC = 4.5–5.5 V, using 500 Ω termination resistance and ≤2.5 ns input rise/fall times. Exceeding 50 pF increases propagation delay variance beyond 5.5 ns and may cause setup/hold violations in 25 MHz SPI interfaces. For heavier loads, add series damping resistors or select a higher-drive variant like 74LVC1G126.
Does the n.c. pin on the XSON6 package require grounding or floating?
Pin 4 is internally unconnected and must remain floating-no soldering, grounding, or routing is permitted. Connecting it risks internal shorting or thermal stress due to mismatched CTE between the pad and die attach. The pad serves only mechanical anchoring and improves reflow yield in high-speed SMT lines.
Can this device drive a 50 Ω transmission line directly?
No. With typical output impedance of ~15 Ω (at VCC = 3.3 V), direct 50 Ω termination causes significant overshoot and reflection. Use a series 33 Ω resistor at the driver output to match 50 Ω lines, or select a dedicated line driver like 74LVC1G123 for true 50 Ω drive capability.
How does IOFF behavior differ between powered-down and deep-sleep MCU states?
IOFF activates only when VCC = 0 V, blocking current regardless of OE or input voltage. During MCU deep-sleep (VCC active but clocks gated), IOFF is inactive-the device remains fully functional. True IOFF protection requires physical power removal or use of an external load switch upstream of VCC.
