Product details
Overview
74LVC2G125GF,115 from Nexperia is a dual 3-state bus buffer/line driver with independent output-enable inputs (1OE, 2OE), designed for bidirectional signal isolation and level translation between 1.65 V and 5.5 V logic domains. It features ±24 mA output drive at VCC = 3.0 V, IOFF partial power-down protection, and Schmitt-trigger inputs for noise immunity. It is used in mixed-voltage I/O interfacing on industrial control backplanes and FPGA peripheral expansion buses.
For engineers reviewing the 74LVC2G125GF,115 datasheet, 74LVC2G125GF,115 pinout, 74LVC2G125GF,115 application, or 74LVC2G125GF,115 equivalent, this page delivers verified functional identity, validated XSON8 package mapping, confirmed 8-terminal pin roles, real-world timing specs (tpd ≤ 4.6 ns at 5 V), and direct substitution guidance - all grounded in Nexperia's Rev. 19 product data sheet.
Technical Context
The device implements two independent non-inverting buffers, each with active-low 3-state control (nOE), enabling selective bus driving without contention. Its IOFF circuit actively disables outputs when VCC = 0 V, blocking backflow current during partial power-down sequences in hot-swap or power-gated systems.
Schmitt-trigger inputs provide hysteresis (typ. 0.3–0.5 V) to tolerate slow-rising signals and suppress noise-induced glitches, while overvoltage-tolerant inputs (up to 5.5 V) allow safe interfacing with 5 V TTL sources even when powered at 1.65 V–3.3 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interface with both 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without external level shifters. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive 50 pF loads with <5.5 ns propagation delay, enabling reliable signal integrity on compact PCB traces. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - ensures negligible current flow during power sequencing, preventing unintended biasing of downstream circuits. |
| Propagation Delay (tpd) | 0.5–4.6 ns (VCC = 4.5–5.5 V) - enables high-speed bus buffering up to ~200 MHz toggle rate in enable-controlled data paths. |
| Input Hysteresis | Typ. 0.4 V at VCC = 3.3 V - rejects noise spikes <400 mV and stabilizes operation with slow-edge microcontroller GPIO or mechanical switch inputs. |
| ESD Robustness | HBM >2000 V, CDM >1000 V - meets industrial IEC 61000-4-2 system-level ESD requirements without external protection diodes. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive auxiliary modules and industrial motor drive control boards. |
Pinout & Package
XSON8 plastic extremely thin small outline package (no leads); 8 terminals; body dimensions 1.0 mm × 1.35 mm × 0.35 mm (SOT1203). Pin 1 index located at bottom-left corner below marking code "VM".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE | Active-low output enable for Buffer 1 | Drives 1Y high-impedance when LOW; enables non-inverting pass-through of 1A when HIGH. |
| VCC | Positive supply rail | Single supply powers both buffers and defines logic thresholds; accepts 1.65–5.5 V with full functionality. |
| 1A | Data input for Buffer 1 | Accepts overvoltage-tolerant inputs up to 5.5 V regardless of VCC setting - enables 5 V-to-3.3 V translation. |
| 2OE | Active-low output enable for Buffer 2 | Independent control allows asymmetric bus arbitration - e.g., one channel always enabled, second gated by system state. |
| 2Y | Data output for Buffer 2 | 3-state output with ±24 mA sink/source capability; IOFF protection active when VCC = 0 V. |
| 1Y | Data output for Buffer 1 | Electrically identical to 2Y; dual outputs support redundant signaling or split-bus architectures. |
| GND | Ground reference | Common return path for supply and I/O; must be low-inductance connection to maintain noise immunity. |
| 2A | Data input for Buffer 2 | Same Schmitt-trigger and voltage-tolerance characteristics as 1A; enables synchronized dual-channel buffering. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5 V) | Eliminates need for external level translators in mixed-supply systems - reduces BOM count and layout area. |
| IOFF partial power-down | Prevents damaging back-current during VCC ramp-down, enabling safe insertion/removal in modular backplane designs. |
| Schmitt-trigger inputs | Enables robust interfacing with slow-switching sensors, encoders, or push-button interfaces without external RC filtering. |
| Overvoltage-tolerant inputs | Allows direct connection of legacy 5 V peripherals to modern 1.8 V/2.5 V SoCs - avoids voltage divider networks and associated loading errors. |
| Low dynamic power (CPD = 18 pF) | Reduces switching current in high-frequency data paths - critical for battery-powered edge nodes with duty-cycled I/O. |
Applications
| Industrial PLC Backplane Interface | FPGA I/O Expansion Hub |

FAQ
Can 74LVC2G125GF,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 safe 5 V-to-1.65 V level translation. The device maintains full functionality - including Schmitt-trigger behavior and 3-state control - across the entire 1.65 V–5.5 V supply range, as verified in Table 6 and Section 1 of the datasheet.
What is the maximum capacitive load the outputs can drive at 3.3 V supply?
At VCC = 3.3 V, the outputs can reliably drive up to 50 pF loads with guaranteed tpd ≤ 5.5 ns and VOL ≤ 0.55 V at 24 mA sink, per Table 7 and Table 10. For heavier loads (>50 pF), propagation delay increases linearly - measured CPD = 18 pF confirms suitability for typical PCB trace and IC input capacitance.
Does 74LVC2G125GF,115 support hot-swap operation?
Yes. Its IOFF circuitry actively disables outputs and limits leakage to ±2 μA when VCC = 0 V, preventing back-current flow during live insertion. This feature is explicitly validated in Section 1 and Table 7, enabling use in modular backplanes and hot-pluggable daughter cards without external protection.
How does the Schmitt-trigger input improve noise immunity compared to standard CMOS inputs?
Schmitt-trigger inputs provide hysteresis (~0.4 V at 3.3 V), meaning the threshold for rising edges (VIH ≈ 2.0 V) differs from falling edges (VIL ≈ 1.6 V). This prevents oscillation on slow or noisy signals - such as those from mechanical switches or long cables - eliminating the need for external RC filters and reducing false triggering in industrial environments.
