Product details
Overview
74AHC1G125GW,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 I²C pull-up domains, microcontroller GPIO expansion, and low-power logic isolation.
For engineers reviewing the 74AHC1G125GW,125 datasheet, 74AHC1G125GW,125 pinout, 74AHC1G125GW,125 application, or 74AHC1G125GW,125 equivalent, this device delivers precise 3-state control timing, symmetrical output impedance, high noise immunity, and verified latch-up robustness (>100 mA) - critical for reliable signal integrity in space-constrained industrial and automotive-adjacent embedded systems.
Technical Context
The 74AHC1G125GW,125 implements a non-inverting buffer with active-low 3-state enable (OE), where output Y follows input A when OE is LOW and enters high-impedance state when OE is HIGH. Its CMOS input threshold scales with VCC (VIH = 0.7×VCC min, VIL = 0.3×VCC max), enabling interoperability across 2.0 V, 3.3 V, and 5.0 V logic domains.
Dynamic performance is characterized by propagation delay (tpd ≤ 7.0 ns at VCC = 5.0 V, CL = 15 pF), enable time (ten ≤ 6.5 ns), and disable time (tdis ≤ 8.5 ns), all measured under defined load and transition conditions. Input capacitance is 10 pF max, and power dissipation capacitance (CPD) is 9 pF - key for estimating dynamic power in high-frequency switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 5.5 V - supports direct interface with 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Input Voltage Range | –0.5 V to 5.5 V - overvoltage-tolerant inputs allow safe connection to 5 V buses even when powered from 3.3 V or lower. |
| Propagation Delay | ≤ 7.0 ns @ VCC = 5.0 V, CL = 15 pF - ensures sub-10 ns timing margin for 50 MHz+ data paths in compact digital subsystems. |
| Output Drive | ±8.0 mA @ VCC = 4.5 V - sufficient to drive 15 pF loads with <0.55 V VOL and >3.70 V VOH across full temperature range. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood, industrial control, and extended-temperature embedded applications. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 2 requirements for board-level ESD robustness. |
| Latch-up Immunity | >100 mA per JESD 78 Class II Level A - prevents destructive latch-up during transient overvoltage events. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, 0.65 mm pitch, 1.3 mm height - optimized for automated SMT assembly and thermal reliability in dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output Enable (active-low) | Asserting LOW enables output Y; HIGH forces Y into high-impedance state - essential for bus arbitration and shared-line contention control. |
| 2 (A) | Data Input | CMOS-compatible input accepting 2.0–5.5 V signals; tolerant of overvoltage up to 5.5 V regardless of VCC. |
| 3 (GND) | Ground Reference | 0 V reference for all input/output thresholds and internal biasing; must be low-impedance for noise immunity. |
| 4 (Y) | Data Output | Non-inverting buffered output with symmetrical rise/fall times and ±8 mA drive capability. |
| 5 (VCC) | Supply Voltage | Primary power rail; decoupling capacitor (100 nF) recommended within 5 mm of pin for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 2.0–5.5 V operation enables drop-in use across legacy 5 V and modern low-voltage MCU platforms without redesign. |
| Overvoltage-Tolerant Inputs | Inputs withstand 5.5 V regardless of VCC - eliminates need for external clamping diodes in mixed-voltage interconnects. |
| Symmetrical Output Impedance | Matched pull-up/pull-down strength ensures consistent rise/fall times and reduces signal distortion on transmission lines. |
| Low Dynamic Power | CPD = 9 pF enables <1 μW/MHz dynamic power at 3.3 V - critical for battery-powered sensor nodes and always-on peripherals. |
| High Noise Immunity | Typical noise margin >0.8 V at VCC = 3.3 V - suppresses false triggering from EMI in motor drives and industrial I/O modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G125GW,125 | TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max) vs. AHC's CMOS thresholds (VIH = 0.7×VCC). | Better suited for interfacing with legacy 5 V TTL outputs; less suitable for 2.0–2.5 V logic domains. | Select when driving from standard 5 V TTL sources; avoid if interfacing with sub-3 V MCUs or battery-supplied logic. |
| SN74LVC1G125DBVR | Narrower supply range (1.65–5.5 V); higher ICC (max 10 μA vs. 40 μA for AHC at 125 °C); identical TSSOP5 footprint. | Lower static current at room temperature but degrades faster above 85 °C; not rated for full –40 °C to +125 °C range. | Prefer for cost-sensitive consumer applications below 85 °C; avoid for automotive or industrial thermal cycling environments. |

FAQ
What is the maximum allowable input voltage relative to VCC?
The 74AHC1G125GW,125 features overvoltage-tolerant inputs rated to 5.5 V absolute maximum, independent of VCC. This allows safe connection to 5 V buses even when powered from 2.0 V or 3.3 V supplies - no external clamping required. Input current remains within specification as long as VI does not exceed –0.5 V or +7.0 V per limiting values table.
Can this device drive a 50 pF capacitive load at 10 MHz?
Yes. At VCC = 5.0 V and CL = 50 pF, propagation delay is ≤ 7.5 ns and output drive is ±8.0 mA, ensuring clean edges and adequate slew rate for 10 MHz square waves. Dynamic power is calculated as PD = CPD × VCC² × fi = 9 pF × (5 V)² × 10 MHz = 2.25 mW - well within the 250 mW total package limit at ambient temperatures below 74 °C.
Is the TSSOP5 package lead-free and RoHS-compliant?
Yes. The 74AHC1G125GW,125 in SOT353-1 (TSSOP5) packaging is manufactured with lead-free terminations and fully complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. The device carries the "Pb-free" marking per Nexperia's standard qualification and is compatible with standard SnAgCu reflow profiles.
How does the 3-state disable timing affect bus arbitration in multi-driver systems?
With tdis ≤ 8.5 ns at VCC = 5.0 V and CL = 50 pF, the output transitions to high-impedance rapidly after OE goes HIGH, minimizing bus contention windows. Combined with ten ≤ 6.5 ns, this enables deterministic turn-around timing for half-duplex protocols like I²C or custom shared-bus interfaces - critical for avoiding data corruption in real-time control loops.
