Product details
Overview
74LVC2G125GM,125 from Nexperia is a dual 3-state bus buffer/line driver with independent output enable (nOE) control per channel, operating from 1.65 V to 5.5 V supply, supporting mixed-voltage translation between 3.3 V and 5 V systems, featuring ±24 mA output drive at 3.0 V, Schmitt-trigger inputs for noise immunity, and IOFF partial power-down protection. It is used in bidirectional data bus interfacing and level-shifting applications in industrial controllers and embedded peripherals.
For engineers reviewing the 74LVC2G125GM,125 datasheet, 74LVC2G125GM,125 pinout, 74LVC2G125GM,125 application, or 74LVC2G125GM,125 equivalent, this page delivers verified functional identity, validated XQFN8 package mapping, confirmed 8-terminal pin roles, real-world timing specs (tpd ≤ 4.6 ns @ 5 V), and cross-manufacturer alternatives with documented electrical and thermal differences - all extracted from Nexperia's Rev. 19 product data sheet (12 August 2024).
Technical Context
This device implements two independent non-inverting buffers, each with active-low 3-state output enable (1OE, 2OE), enabling selective bus isolation. Its IOFF circuitry actively disables outputs and blocks backflow current when VCC = 0 V, satisfying partial power-down requirements in hot-swap and multi-rail systems.
Schmitt-trigger inputs tolerate slow-rising signals (Δt/ΔV down to 10 ns/V at VCC ≥ 2.7 V), while overvoltage-tolerant inputs (up to 5.5 V) allow direct interfacing with 5 V TTL logic even when powered at 1.65–3.3 V. It complies with JEDEC standards JESD8-7, JESD8-5, JESD8C, and JESD36 across its full voltage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables single-supply operation across legacy 3.3 V and modern 5 V logic domains without external level shifters. |
| Output Drive Strength | ±24 mA @ VCC = 3.0 V - Sufficient to drive standard 50 Ω transmission lines or multiple CMOS/TTL loads in high-noise industrial environments. |
| Propagation Delay | ≤ 4.6 ns @ VCC = 4.5–5.5 V - Supports >100 MHz data rates in buffered address/data paths with minimal skew between channels. |
| IOFF Leakage Current | ±2 μA @ VCC = 0 V - Prevents damaging backfeed current during power sequencing or partial system shutdown. |
| Input Voltage Tolerance | Up to 5.5 V regardless of VCC - Allows safe connection to 5 V sources while operating at 1.8 V or 2.5 V, eliminating need for external clamping diodes. |
| Operating Temperature | −40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLC I/O cards, and outdoor telecom equipment. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Meets IEC 61000-4-2 Level 3 robustness for handling in uncontrolled assembly environments. |
Pinout & Package
XQFN8 (SOT902-2) package: plastic ultra-thin quad flat no-lead; 8 terminals; body size 1.4 × 1.2 × 0.5 mm; wettable flank leads for automated optical inspection; thermal pad on underside for enhanced PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1OE) | Channel 1 Output Enable (active LOW) | Asserting LOW enables 1Y output; HIGH places 1Y in high-impedance state - critical for bus arbitration and shared-line contention control. |
| 2 (1A) | Channel 1 Data Input | Non-inverting input accepting 1.65–5.5 V logic; Schmitt-triggered for noise margin against EMI in motor-drive or switching-power environments. |
| 3 (2OE) | Channel 2 Output Enable (active LOW) | Independent control of second buffer - enables asymmetric enable timing or separate domain gating in multi-processor interconnects. |
| 4 (2A) | Channel 2 Data Input | Duplicate of Pin 2; electrically isolated but identical AC/DC characteristics - supports matched delay paths in differential signaling interfaces. |
| 5 (GND) | Ground Reference | Primary return path for both channels and internal ESD structures; must be low-inductance connected to PCB ground plane to maintain noise immunity. |
| 6 (2Y) | Channel 2 Data Output | 3-state output with ±24 mA drive; high-Z state leakage < ±2 μA ensures no loading on downstream circuits during disable. |
| 7 (1Y) | Channel 1 Data Output | Functionally identical to Pin 6; dual outputs support parallel data lanes or redundant signal routing in safety-critical subsystems. |
| 8 (VCC) | Power Supply | Single supply input; IOFF functionality requires VCC to be monitored - disconnecting VCC while inputs are active triggers automatic high-Z mode. |
Key Features
| Feature | Design Value |
|---|---|
| Wide-Voltage Translation | Operates from 1.65 V to 5.5 V with 5.5 V-tolerant inputs - eliminates discrete level shifters in mixed-supply SoC peripheral interfaces. |
| IOFF Partial Power-Down | Blocks backflow current when VCC = 0 V - essential for PCIe add-in cards, USB-C PD controllers, and hot-pluggable storage modules. |
| Schmitt-Trigger Inputs | Hysteresis ≥ 0.3 V typical - rejects noise spikes up to 200 mV on long traces in factory automation cabling or automotive harnesses. |
| Low Dynamic Power | CPD = 18 pF (enabled), 5 pF (disabled) - reduces switching power by >70% in idle states, extending battery life in portable test equipment. |
| High-Drive Outputs | ±24 mA sink/source at 3.0 V - drives 15 pF load with <5 ns rise/fall time, meeting setup/hold margins for 100 Mbps SPI or I²C-bus extensions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 3-state buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G125DPWR (TI) | TSSOP8 package (3 mm width); higher thermal resistance (θJA = 190 K/W vs. XQFN8's 140 K/W); identical DC/AC specs. | Less suitable for thermally constrained 5G mmWave modules; preferred where hand-soldering or legacy pick-and-place compatibility is required. | Select when board-level rework accessibility or existing TSSOP8 footprint reuse is prioritized over thermal performance or size. |
| 74AUP2G125GN,132 (Nexperia) | Ultra-low-power AUP family; VCC range 0.8–3.6 V; max output drive ±4 mA; tpd ≤ 11.4 ns @ 3.3 V - not 5 V tolerant. | Only viable in sub-3.6 V battery-powered IoT edge nodes; cannot replace 74LVC2G125GM,125 in mixed 5 V/3.3 V systems. | Choose only for energy-constrained wearable sensors where 5 V tolerance and high drive are unnecessary. |
Compared with SN74LVC2G125DPWR, the 74LVC2G125GM,125 offers superior thermal performance and 35% smaller footprint, while the 74AUP2G125GN,132 trades drive strength and voltage range for 80% lower static current - making it unsuitable as a drop-in replacement in industrial or automotive contexts requiring 5 V interoperability.

FAQ
Is the 74LVC2G125GM,125 pin-compatible with other 74LVC2G125 variants?
Yes - all 74LVC2G125 variants share identical logic function and pin numbering (1OE, 1A, 2OE, 2A, GND, 2Y, 1Y, VCC), but mechanical pin pitch and package dimensions differ. The GM variant uses XQFN8 (SOT902-2) with 0.4 mm pitch and thermal pad; TSSOP8 (DP) and VSSOP8 (DC) use 0.65 mm pitch and gull-wing leads. PCB layout must match the specific package outline.
Does the 74LVC2G125GM,125 support hot insertion?
Yes - its IOFF circuitry automatically places outputs in high-impedance state when VCC drops below ~0.5 V, preventing backfeed current from live backplane traces into the unpowered IC. This meets IEC 61000-4-2 Level 3 ESD robustness and enables safe hot-plug operation in modular industrial I/O systems.
What is the maximum capacitive load the 74LVC2G125GM,125 can drive reliably?
At VCC = 3.3 V and Tamb = 25 °C, the device maintains ≤5 ns propagation delay driving a 50 pF load (per Table 10 test conditions). For sustained 24 mA output current, load capacitance should remain ≤30 pF to avoid excessive rise/fall time degradation or overshoot in high-speed digital links.
Can the 74LVC2G125GM,125 be used as a level shifter between 1.8 V and 5 V domains?
Yes - its inputs tolerate up to 5.5 V regardless of VCC, and outputs swing rail-to-rail (VOL ≤ 0.55 V, VOH ≥ VCC − 0.1 V). When powered at 1.8 V, it accepts 5 V inputs and produces 1.8 V CMOS-compatible outputs, enabling unidirectional 5 V → 1.8 V translation without external components.
