Product details
Overview
74LVC1G126GM,115 from Nexperia is a single 3-state bus buffer/line driver with Schmitt-trigger inputs, designed for level translation between 1.65 V–5.5 V logic domains in mixed-voltage systems. It delivers ±24 mA output drive at VCC = 3.0 V, supports IOFF partial power-down protection, and operates across –40 °C to +125 °C. Used in I²C bus isolation, sensor interface signal conditioning, and FPGA I/O expansion.
For engineers reviewing the 74LVC1G126GM,115 datasheet, 74LVC1G126GM,115 pinout, 74LVC1G126GM,115 application, or 74LVC1G126GM,115 equivalent, this page provides verified functional identity, XSON6 package mapping, terminal-level design meaning, thermal derating data, and real-world use-case validation - all extracted from Nexperia's Rev. 18.1 (2024) product data sheet.
Technical Context
This device implements a non-inverting buffer with active-high 3-state enable (OE), enabling bidirectional bus control in compact digital subsystems. Its Schmitt-trigger inputs tolerate slow-rising signals (Δt/ΔV ≤ 20 ns/V at VCC = 1.65 V), eliminating external hysteresis components in noisy industrial sensor interfaces.
The IOFF circuit ensures <1 μA power-off leakage when VCC = 0 V, preventing backflow current during hot-swap or partial system shutdown. Input overvoltage tolerance up to 5.5 V allows safe interfacing with 5 V peripherals while powered from 1.8 V or 3.3 V rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.65 V to 5.5 V - enables direct operation from 1.8 V, 2.5 V, 3.3 V, and 5 V rails without level shifters |
| Output drive strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 pF loads with <6 ns propagation delay in 3.3 V systems |
| Propagation delay (A→Y) | 0.5 ns (min) to 4.5 ns (max) at VCC = 3.0–3.6 V - meets timing budgets for high-speed GPIO expansion in microcontroller peripherals |
| IOFF leakage current | ±2 μA max at VCC = 0 V - guarantees safe hot-plug operation without damaging downstream logic |
| ESD robustness | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events in automated assembly environments |
| Operating temperature | –40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and outdoor IoT node applications |
| Input hysteresis | Typical 0.3 V at VCC = 3.3 V - rejects noise on long traces or unshielded sensor lines without external RC filtering |
Pinout & Package
XSON6 plastic extremely thin small outline package (SOT886); no leads; 6 terminals; body dimensions 1.0 mm × 1.45 mm × 0.5 mm; wettable flanks not present; thermal resistance θJA = 220 K/W (JEDEC standard PCB).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OE) | Output enable input | Active-high control: drives Y to high-impedance when low; must be pulled high or low via 10 kΩ resistor in static designs |
| 2 (A) | Data input | Non-inverting input with Schmitt-trigger threshold; accepts 0–5.5 V regardless of VCC; immune to ringing on 10 cm PCB traces |
| 3 (GND) | Ground reference | 0 V return path for all internal logic and output drivers; requires low-inductance connection to PCB ground plane |
| 4 (Y) | Data output | 3-state buffered output; sinks or sources up to 24 mA; high-impedance state isolates bus segments during arbitration |
| 5 (n.c.) | No-connect terminal | Internally unconnected; must remain floating - no routing, soldering, or grounding permitted |
| 6 (VCC) | Power supply | Primary supply rail; bypass capacitor (100 nF X7R) required within 2 mm of pin for stable 50 MHz switching |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 1.65–5.5 V operation eliminates need for separate voltage translators in multi-rail embedded systems |
| IOFF partial power-down | Enables live insertion into powered backplanes by blocking reverse current flow when VCC = 0 V |
| Schmitt-trigger inputs | Provides 0.3–0.5 V hysteresis margin, allowing reliable operation with slow edges from mechanical switches or analog sensors |
| Overvoltage-tolerant inputs | Accepts 5.5 V inputs while powered from 1.65 V - simplifies interconnection with legacy 5 V controllers |
| Low dynamic power | CPD = 25 pF (enabled), 6 pF (disabled) - reduces switching losses in battery-powered edge nodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | Active-low OE; identical pinout and electrical specs except enable polarity | Requires inverted control signal from host MCU; unsuitable where OE is hardwired high | Select when existing firmware uses active-low enable logic or pull-up/pull-down constraints favor low-active control |
| 74LVC1G17GW,125 | Non-inverting Schmitt-trigger buffer without 3-state; TSSOP5 package (5-pin) | Lacks bus isolation capability; fixed output drive only - no high-Z state for shared-line arbitration | Choose only for point-to-point signal conditioning where bus contention is impossible and space permits larger TSSOP5 footprint |
Compared with SN74LVC1G125DBVR and 74LVC1G17GW,125, the 74LVC1G126GM,115 uniquely combines active-high 3-state control, XSON6 ultra-compact packaging, and guaranteed 125 °C operation - making it optimal for space-constrained, thermally demanding, and multi-drop digital interfaces.

FAQ
Can 74LVC1G126GM,115 operate with VCC = 1.65 V while accepting 5 V inputs?
Yes. The device features overvoltage-tolerant inputs rated to 5.5 V independent of VCC. At VCC = 1.65 V, VIH = 0.65 × VCC ≈ 1.07 V and VIL = 0.35 × VCC ≈ 0.58 V, ensuring reliable recognition of 5 V TTL logic levels without damage or malfunction.
What is the significance of the n.c. pin in the XSON6 package?
Pin 5 is internally unconnected and must remain electrically floating. It is not a thermal pad or ground tie - routing, soldering, or grounding this terminal violates Nexperia's qualification and may cause parametric drift or premature failure due to parasitic coupling.
How does IOFF behavior protect downstream circuitry during power sequencing?
When VCC = 0 V, the IOFF circuit disables both input and output buffers, limiting leakage current to ±2 μA. This prevents backflow current from powered downstream ICs (e.g., 5 V microcontrollers) into the unpowered 74LVC1G126GM,115, avoiding latch-up or unintended logic states during staggered power-up sequences.
Is the XSON6 package compatible with standard reflow profiles for lead-free assembly?
Yes. SOT886 (XSON6) is qualified for IPC/JEDEC J-STD-020D moisture sensitivity level 1 and withstands peak reflow temperatures up to 260 °C. Its 0.5 mm height and exposed copper terminals support full-profile lead-free soldering with standard stencil thicknesses (125 μm) and aperture ratios ≥1.5.
