Product details
Overview
74AHC1G125GV-Q100 from Nexperia is a single-channel 3-state bus buffer/line driver with overvoltage-tolerant inputs (up to 5.5 V), CMOS-level input compatibility, and AEC-Q100 Grade 1 qualification for automotive use. It operates from 2.0 V to 5.5 V supply, delivers ≤7.0 ns propagation delay at 5 V/50 pF, and features symmetrical output impedance for clean signal integrity in bidirectional bus interfaces.
For engineers reviewing the 74AHC1G125GV-Q100 datasheet, 74AHC1G125GV-Q100 pinout, 74AHC1G125GV-Q100 application, or 74AHC1G125GV-Q100 equivalent, this device serves as a voltage-translation-capable unidirectional buffer in CAN/LIN subsystems, sensor interface multiplexing, and automotive body control modules where rail-to-rail input tolerance and low-power 3-state control are required.
Technical Context
This device implements a single non-inverting buffer with active-low 3-state enable (OE), supporting mixed-voltage system interfacing via overvoltage-tolerant inputs that accept up to 5.5 V regardless of VCC (2.0–5.5 V). Its logic function follows standard IEEE/IEC 60617 truth table behavior: output Y equals input A when OE = LOW; Y is high-impedance when OE = HIGH.
The SC-74A (SOT753) package supports thermal performance up to +125 °C ambient, with total power dissipation derating at 3.8 mW/K above 85 °C. Input leakage remains ≤2.0 μA across temperature, and output drive capability is ±8 mA at VCC = 4.5 V, enabling direct connection to standard CMOS loads without external termination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - Enables operation across 3.3 V and 5 V domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe interfacing with higher-voltage peripherals even when VCC = 2.0 V. |
| Propagation Delay (tpd) | ≤5.5 ns at VCC = 5.0 V, CL = 15 pF - Supports >100 MHz data rates in short-bus applications. |
| Output Drive Strength | ±8.0 mA at VOH/VOL limits - Sufficient to drive 15 pF load with <0.55 V VOL at 4.0 mA sink. |
| Operating Temperature | −40 °C to +125 °C - Qualified per AEC-Q100 Grade 1 for under-hood automotive environments. |

| Quiescent Supply Current | ≤40 μA at VCC = 5.5 V - Enables ultra-low static power in always-on vehicle subsystems. |
Pinout & Package
74AHC1G125GV-Q100 uses the SC-74A (SOT753) surface-mount package: plastic, 5-terminal, 1.25 mm body width, 0.95 mm lead pitch, and 1.1 × 0.9 mm footprint. Pin 1 (OE) is located at the lower-left corner beneath the marking "A25".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low output enable | Drives Y to high-impedance when HIGH; enables buffer pass-through when LOW. |
| 2 (A) | Data input | CMOS-compatible input accepting 0–5.5 V; no internal pull-up/down. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry and output current sinking. |
| 4 (Y) | Buffered output | Non-inverted, 3-state output with symmetrical rise/fall times and ±8 mA drive. |
| 5 (VCC) | Positive supply | Primary power rail; powers internal logic and output stage; tolerant to 7.0 V transient. |
Key Features

Applications
| Automotive Body Control Module (BCM) | Infotainment System I/O Expansion |
|---|---|
Use Scenario: Isolating microcontroller GPIOs from high-noise door lock actuators and window motor drivers. IC Role / Device Role / Timing Role: Unidirectional 3-state buffer enabling software-controlled isolation of MCU pins from noisy loads. Use Value: Prevents backfeed and noise coupling into MCU while maintaining fast response (<7 ns) for real-time actuator control. |
Use Scenario: Expanding I²C or SPI peripheral count on head unit SoC with limited native GPIOs. IC Role / Device Role / Timing Role: Bus buffer isolating secondary I²C slave devices from main controller during hot-swap or fault conditions. Use Value: Enables hot-plug-safe peripheral addition without disrupting primary bus timing or causing address conflicts. |
| Advanced Driver Assistance Systems (ADAS) Sensor Hub | Automotive Gateway Controller Interface |
Use Scenario: Multiplexing analog sensor outputs (e.g., radar proximity, ambient light) onto shared ADC input lines. IC Role / Device Role / Timing Role: Signal routing buffer with precise enable timing to prevent channel crosstalk during sampling windows. Use Value: Ensures <10 ns enable/disable skew between sensors, preserving time-of-flight measurement accuracy. |
Use Scenario: Level-shifting and buffering LIN bus signals between gateway MCU (3.3 V) and legacy 12 V LIN transceivers. IC Role / Device Role / Timing Role: Voltage-tolerant line driver translating logic levels while maintaining LIN physical layer timing compliance. Use Value: Eliminates need for discrete level-shifters; maintains <15 ns propagation delay margin for LIN 19.2 kbps timing budget. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G125GV-Q100 | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical pinout, timing, and packaging. | Better suited for legacy 5 V TTL logic interfacing; less suitable for pure CMOS 3.3 V systems with marginal noise margins. | Select when interfacing with older 5 V microcontrollers or discrete TTL gates requiring 2.0 V VIH threshold. |
| SN74LVC1G125DBVR | Lower VCC range (1.65–5.5 V), higher ICC (max 10 μA vs. 40 μA), same SC-70-5 package but not AEC-Q100 qualified. | Not automotive-qualified; intended for industrial/commercial use only; lacks AEC-Q100 test documentation. | Select for cost-sensitive non-automotive designs requiring wider low-voltage support down to 1.65 V. |
Compared with 74AHCT1G125GV-Q100, the AHC variant offers tighter VIH/VIL thresholds for robust CMOS noise immunity, while SN74LVC1G125DBVR trades automotive qualification for broader low-voltage operation-making the 74AHC1G125GV-Q100 optimal for safety-critical 3.3 V/5 V mixed-signal automotive nodes.

FAQ
Is 74AHC1G125GV-Q100 pin-compatible with 74AHCT1G125GV-Q100?
Yes - both share identical SC-74A (SOT753) pinout, package dimensions, and terminal assignments. The only functional difference is input threshold: AHC uses CMOS-compatible VIH (≥70% VCC), while AHCT uses TTL-compatible VIH (≥2.0 V). No PCB redesign is needed for substitution.
What is the maximum capacitive load this buffer can drive reliably?
The device is characterized up to 50 pF load capacitance with guaranteed timing (tpd ≤7.5 ns at VCC = 5 V). Driving >50 pF may increase propagation delay and reduce edge rate but will not damage the part; for loads >75 pF, consider adding series termination or using a higher-drive buffer.
Does this part support hot insertion or live bus connection?
Yes - its overvoltage-tolerant inputs (to 5.5 V) and high-impedance OFF-state (IOZ ≤10 μA) allow safe connection to powered buses. However, OE must be held LOW before VCC ramp-up to avoid undefined output states during power sequencing.
How does the 3-state disable timing affect system-level bus arbitration?
tdis (disable time) is ≤9.5 ns at VCC = 5 V/CL = 50 pF, ensuring rapid bus release. This allows tight arbitration windows in multi-master systems - e.g., in LIN cluster networks, it guarantees <10 ns bus turnaround between master and slave transmissions without collision.
