Product details
Overview
74AHC1G125GV,125 from Nexperia is a single CMOS bus buffer/line driver with 3-state output, overvoltage-tolerant inputs (up to 5.5 V), wide supply range (2.0–5.5 V), and operation from –40 °C to +125 °C. It functions as a level-translating unidirectional buffer in mixed-voltage digital interfaces, such as between 3.3 V logic and 5 V peripherals.
For engineers reviewing the 74AHC1G125GV,125 datasheet, 74AHC1G125GV,125 pinout, 74AHC1G125GV,125 application, or 74AHC1G125GV,125 equivalent, this device supports voltage translation, low-power bus driving, high-noise-immunity signal conditioning, and compact PCB integration in space-constrained embedded systems.
Technical Context
This device implements a single-channel non-inverting buffer with active-low 3-state enable control (OE). Its overvoltage-tolerant inputs allow direct connection to 5.5 V signals while powered from as low as 2.0 V, enabling seamless interfacing across voltage domains without external level shifters.
The logic function follows standard bus buffer behavior: when OE is LOW, Y = A; when OE is HIGH, Y is high-impedance. Propagation delays are tightly balanced (e.g., 3.4 ns typ at VCC = 5.0 V, CL = 15 pF), and output impedance is symmetrical for clean rise/fall times.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.0 V to 5.5 V - supports dual-rail system integration and battery-powered operation down to 2 V. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - enables safe interfacing with higher-voltage logic without clamping diodes or resistors. |
| Propagation Delay (A→Y) | 3.4 ns (typ) at VCC = 5.0 V, CL = 15 pF - ensures sub-5 ns timing for high-speed data paths in microcontroller peripheral buses. |
| Output Drive Strength | ±8.0 mA at VCC = 4.5 V - sufficient to drive 15 pF loads across 10 cm PCB traces or multiple CMOS inputs. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive modules, industrial controllers, and extended-range power supplies. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 2 requirements for robust handling in automated assembly lines. |
| Power Dissipation | 250 mW max (SOT753 package, derated above 85 °C) - enables continuous operation in thermally constrained enclosures. |
Pinout & Package
74AHC1G125GV,125 uses the SC-74A (SOT753) surface-mount package: plastic, 5-lead, body size 3.1 mm × 1.7 mm × 1.3 mm, with gull-wing leads and pin 1 indicator in lower-left corner below marking "A25".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Active-low output enable | Drives Y into high-impedance when HIGH; enables pass-through (Y = A) when LOW - used for bus arbitration and shared-line contention control. |
| 2 (A) | Data input | CMOS-level input accepting 0–VCC logic; tolerant to 5.5 V regardless of VCC - allows direct connection to legacy 5 V outputs. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry and output current - must be low-inductance and adjacent to VCC for stable noise immunity. |
| 4 (Y) | 3-state buffered output | Non-inverting output with symmetrical drive; enters high-Z on OE HIGH - prevents bus contention in multi-driver configurations. |
| 5 (VCC) | Supply voltage | Primary power rail (2.0–5.5 V); decoupling capacitor (100 nF) required within 3 mm for transient current stability. |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-tolerant inputs | Inputs withstand 5.5 V even at VCC = 2.0 V - eliminates need for external level-shifting components in mixed-voltage designs. |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures <10% duty-cycle distortion on clock or data signals - critical for timing-critical serial links. |
| CMOS low-power dissipation | ICC ≤ 40 μA max at VCC = 5.5 V - reduces quiescent current in always-on sensor interface nodes and battery-backed subsystems. |
| Balanced propagation delays | tPLH and tPHL differ by <0.5 ns (typ) - maintains signal integrity in differential-pair routing or matched-length trace applications. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - prevents destructive latch-up during hot-swap or ESD events in field-deployed equipment. |
Applications
| Industrial PLC I/O Expansion | Automotive Body Control Module |
|---|---|

| Consumer IoT Sensor Hub | Medical Portable Monitor Interface |
Use Scenario: Interfacing multiple I²C-compatible sensors (3.3 V) with a 5 V display controller in smart home hubs. IC Role / Device Role / Timing Role: Voltage-translating bus buffer placed on SDA/SCL lines to resolve domain mismatch without adding capacitance or delay skew. Use Value: 3.4 ns propagation delay preserves I²C timing margins; 1.5 pF input capacitance minimizes bus loading on 400 kHz operation. |
Use Scenario: Buffering analog front-end ADC control signals (e.g., CS, RD) between a low-power 1.8 V SoC and 3.3 V medical-grade ADC IC. IC Role / Device Role / Timing Role: Low-noise, high-immunity signal conditioner ensuring glitch-free sampling trigger delivery in ECG/SpO₂ modules.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G125GV,125 | TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V) vs. CMOS thresholds in AHC variant. | Better suited for legacy 5 V TTL logic families; less suitable for 2.0–3.3 V-only systems due to higher VIH requirement. | Select AHCT version only when interfacing with standard TTL outputs; otherwise AHC offers wider VCC flexibility and lower static current. |
| SN74LVC1G125DBVR | Lower VCC range (1.65–5.5 V); higher drive (±32 mA); different pinout (SOT-23-5, pin 1 = OE, pin 2 = GND). | Supports 1.8 V logic directly; requires PCB redesign due to incompatible footprint and pin assignment. | Choose LVC only when 1.65 V operation or >±8 mA drive is mandatory; AHC provides superior noise margin and thermal performance at 125 °C. |
Compared with 74AHCT1G125GV,125, the AHC variant delivers broader supply compatibility and lower ICC, while SN74LVC1G125DBVR offers higher drive but sacrifices thermal rating and introduces layout incompatibility - making 74AHC1G125GV,125 optimal for mixed-voltage, high-reliability industrial use.

FAQ
What is the maximum input voltage the 74AHC1G125GV,125 can tolerate when VCC = 2.0 V?
The device supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level. When powered at 2.0 V, inputs may safely accept 0–5.5 V signals without damage or functional degradation, enabling direct connection to 5 V peripherals without external protection.
Can the 74AHC1G125GV,125 drive a 50 pF load at 10 MHz while maintaining signal integrity?
Yes - with tpd = 4.8 ns (max) and tdis = 5.7 ns (max) at VCC = 4.5 V and CL = 50 pF, the device delivers clean edges and minimal jitter. Its symmetrical output impedance and 1.5 pF input capacitance ensure stable operation across full frequency range without overshoot or ringing.
Is the 74AHC1G125GV,125 pin-compatible with the 74AHCT1G125GV,125?
Yes - both share identical SC-74A (SOT753) packaging and identical pinout: Pin 1 = OE, Pin 2 = A, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC. The only functional difference lies in input threshold levels, not physical layout or electrical pin behavior.
Does the 74AHC1G125GV,125 require external pull-up or pull-down resistors on OE or A pins?
No - OE and A have CMOS-compatible input structure with negligible leakage (<2.0 μA) and defined logic thresholds. External resistors are unnecessary unless specific fail-safe states (e.g., default high-Z on power-up) are required via pull-down on OE.
