Product details
Overview
74LVC2G126GF,115 from Nexperia is a dual 3-state bus buffer/line driver with independent output enable (nOE) control per channel, Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and 1.65 V to 5.5 V supply operation. It enables level translation between 3.3 V and 5 V domains in compact XSON8 (SOT1089) packages and is rated for -40 °C to +125 °C ambient operation.
For engineers reviewing the 74LVC2G126GF,115 datasheet, 74LVC2G126GF,115 pinout, 74LVC2G126GF,115 application, or 74LVC2G126GF,115 equivalent, this device supports mixed-voltage signal routing in space-constrained industrial controllers, portable instrumentation interfaces, and low-power I/O expansion modules where rail-to-rail input tolerance and high-impedance isolation are required.
Technical Context
This device implements two independent non-inverting buffers, each with active-HIGH 3-state output enable (1OE, 2OE), Schmitt-trigger input thresholds (ΔV = ~0.3–0.8 V hysteresis), and IOFF circuitry that disables outputs and blocks backflow current when VCC = 0 V. Inputs tolerate up to 5.5 V regardless of VCC level, enabling robust interfacing across voltage domains.
Propagation delay ranges from 0.5 ns (VCC = 5.5 V) to 12.5 ns (VCC = 1.65 V); enable/disable times are ≤4.4 ns at 5 V. The logic function table confirms transparent pass-through (nA → nY) when nOE = HIGH and high-impedance (Z) when nOE = LOW - no latching or inversion occurs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports single-supply operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic families. |
| Input Voltage Tolerance | Up to 5.5 V - allows direct connection to 5 V TTL or CMOS outputs even when VCC = 1.65 V. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive standard 50 Ω transmission lines or multiple CMOS loads. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - prevents damaging back-current during hot-swap or partial power-down sequences. |
| Propagation Delay | 0.5 ns to 12.5 ns - scales inversely with VCC; enables timing-critical data path buffering in high-speed digital systems. |
| Operating Temperature | -40 °C to +125 °C - qualified for extended industrial and under-hood automotive auxiliary applications. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets JEDEC JS-001/JS-002 Class 2/C3 for robust handling in automated assembly. |
Pinout & Package
XSON8 package (SOT1089): extremely thin small outline, no leads, 8-terminal surface-mount device with body dimensions 1.35 mm × 1.0 mm × 0.5 mm and pin 1 indicator in lower-left corner below marking "VN".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OE | Active-HIGH output enable for Channel 1 - drives 1Y into high-impedance when LOW. |
| 2 | 1A | Data input for Channel 1 - accepts 1.65–5.5 V signals with Schmitt-trigger hysteresis. |
| 3 | 2Y | Data output for Channel 2 - provides ±24 mA drive capability and rail-to-rail swing. |
| 4 | GND | Ground reference - must be connected before VCC to ensure proper IOFF activation during power sequencing. |
| 5 | 2A | Data input for Channel 2 - electrically identical to 1A; supports independent dual-channel buffering. |
| 6 | 1Y | Data output for Channel 1 - isolated via 3-state control; compatible with bus-sharing topologies. |
| 7 | 2OE | Active-HIGH output enable for Channel 2 - fully independent of 1OE for asymmetric enable control. |
| 8 | VCC | Positive supply - powers internal logic and output drivers; IOFF activates automatically if pulled to 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable operation with slow-rising or noisy signals (e.g., mechanical switch debouncing or long PCB traces). |
| IOFF partial power-down | Prevents destructive back-current flow when VCC is unpowered while inputs/outputs remain live - critical for hot-plug systems. |
| Overvoltage-tolerant inputs | Accepts 5.5 V inputs regardless of VCC setting - eliminates need for external level-shifting components in mixed-voltage designs. |
| Wide temperature range | Specified from -40 °C to +125 °C - supports deployment in industrial motor drives, outdoor sensor nodes, and power supply monitoring circuits. |
| Low dynamic power dissipation | CPD = 17 pF (enabled), 5 pF (disabled) - reduces switching-related power loss in battery-powered or thermally constrained applications. |

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 |
|---|---|---|---|
| SN74LVC2G126DPWR | TSSOP8 package (3 mm width); higher thermal resistance (4.6 mW/K derating above 96 °C); same electrical specs. | Better manual solderability and probe access; less suitable for ultra-dense layouts requiring <1.5 mm height clearance. | Select when board-level rework or in-circuit testing is prioritized over footprint minimization. |
| 74LVC2G126GN,115 | XSON8 package (1.2 mm × 1.0 mm × 0.35 mm); thinner profile but lower Ptot derating threshold (4.2 mW/K above 90 °C). | Superior fit for ultra-thin wearable electronics; reduced heat dissipation margin under sustained 24 mA load at 125 °C. | Select only when vertical space is constrained to <0.4 mm and peak output current remains <12 mA. |

FAQ
Can 74LVC2G126GF,115 operate with VCC = 1.65 V while accepting 5 V inputs?
Yes. Its inputs are overvoltage tolerant up to 5.5 V regardless of VCC level, allowing direct connection to 5 V sources even at minimum 1.65 V supply. This is confirmed in Table 6 (Recommended Operating Conditions) and Table 5 (Limiting Values) of the datasheet, where VI(max) = +6.5 V and VI is specified up to 5.5 V under normal operation.
What happens to outputs during power-down (VCC = 0 V)?
When VCC drops to 0 V, the integrated IOFF circuitry automatically places both outputs (1Y and 2Y) into high-impedance state and limits leakage current to ±2 μA maximum (Table 7). This prevents back-current flow from live inputs or outputs into the unpowered IC - a requirement verified per JESD78 latch-up and JEDEC JS-001 ESD standards.
Is the 74LVC2G126GF,115 pin-compatible with other 74LVC2G126 variants?
No. While all 74LVC2G126 variants share identical logic functionality and pin functions, the 74LVC2G126GF,115 uses SOT1089 (XSON8) with 1.35 × 1.0 mm body and specific pad layout. It is not mechanically or solder-reflow compatible with TSSOP8 (SOT505-2), VSSOP8 (SOT765-1), or other XSON8 variants like SOT1116 due to differing terminal pitch, size, and thermal pad configuration.
Does this device support hot-swap insertion into a live backplane?
Yes - its IOFF feature and overvoltage-tolerant inputs make it suitable for hot-swap applications. When inserted into a powered system, the unpowered VCC causes IOFF to activate immediately, placing outputs in high-Z and limiting input/output leakage to ±2 μA. This behavior is explicitly validated in partial power-down applications per Section 1 of the datasheet and aligns with IEC 61000-4-2 ESD immunity requirements.
