Product details
Overview
74LVC2G125DC,125 from Nexperia is a dual 3-state bus buffer/line driver with independent output-enable inputs (1OE, 2OE), designed for level translation between 3.3 V and 5 V logic domains. It features ±24 mA output drive at VCC = 3.0 V, IOFF partial power-down protection, Schmitt-trigger inputs for noise immunity, and operates across -40 °C to +125 °C. Used in bidirectional data bus isolation and mixed-voltage interface circuits.
For engineers reviewing the 74LVC2G125DC,125 datasheet, 74LVC2G125DC,125 pinout, 74LVC2G125DC,125 application, or 74LVC2G125DC,125 equivalent, key selection criteria include 3-state timing (tdis ≤ 4.6 ns at 5.5 V), overvoltage-tolerant inputs (to 5.5 V), IOFF-enabled safe power sequencing, and VSSOP8 package compatibility with high-density PCB layouts.
Technical Context
This device implements two independent non-inverting buffers, each with active-low 3-state control. The IOFF circuit disables outputs and blocks backflow current when VCC = 0 V, enabling hot-insertion and partial power-down system architectures. Schmitt-trigger inputs accept slow-rising signals (Δt/ΔV down to 10 ns/V at VCC ≥ 2.7 V), eliminating external hysteresis components.
It complies with JEDEC standards JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), and JESD36 (4.5–5.5 V), supporting interoperability across legacy and modern logic families. Input voltage tolerance up to 5.5 V allows direct connection to 5 V TTL outputs while powered from 1.65–5.5 V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables single-supply operation across LVC, LV, and TTL logic families without level shifters. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to drive 50 Ω transmission lines or multiple CMOS inputs under worst-case conditions. |
| Propagation Delay | 0.5–5.5 ns (VCC = 3.0–3.6 V) - Supports >100 MHz data rates in point-to-point bus applications. |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - Prevents damaging backflow current during power sequencing or hot-swap events. |
| Input Voltage Tolerance | Up to 5.5 V regardless of VCC - Allows 5 V signal inputs even when powered from 1.8 V or 2.5 V rails. |
| Operating Temperature | -40 °C to +125 °C - Qualified for industrial and extended-temperature embedded control environments. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - Robust handling in automated assembly and field-replaceable module integration. |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; pin 1 index located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OE | Active-low output enable for Channel 1 | Drives 1Y high-impedance when LOW; enables non-inverting pass-through of 1A when HIGH. |
| VCC | Positive supply rail | Single supply input (1.65–5.5 V); powers both channels and IOFF circuitry. |
| 1A | Data input for Channel 1 | Schmitt-trigger buffered input; accepts 0–5.5 V regardless of VCC value. |
| 2OE | Active-low output enable for Channel 2 | Independent control of 2Y; supports asymmetric bus gating in multi-drop systems. |
| 2Y | Data output for Channel 2 | 3-state CMOS output with ±24 mA drive; compatible with 50 Ω termination and stub-free routing. |
| 1Y | Data output for Channel 1 | Electrically identical to 2Y; enables dual-channel isolated buffering on one die. |
| GND | Ground reference | 0 V return path for all internal logic and I/O; must be low-inductance for EMI control. |
| 2A | Data input for Channel 2 | Functionally identical to 1A; supports differential or mirrored signal routing. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (1.65–5.5 V) | Eliminates need for separate voltage translators in mixed-supply systems such as FPGA I/O banks interfacing with microcontrollers. |
| IOFF partial power-down | Prevents current backflow when VCC is off, enabling safe insertion into live backplanes or modular subsystems without system reset. |
| Schmitt-trigger inputs | Accepts slow or noisy signals (e.g., mechanical switch debouncing, long traces) without external RC filtering or hysteresis components. |
| Overvoltage-tolerant inputs | Directly interfaces 5 V TTL outputs while operating from 1.8 V or 2.5 V rails-no external clamping diodes required. |
| High noise immunity | Input hysteresis ≥ 0.3 V at VCC = 3.3 V reduces susceptibility to ground bounce and crosstalk in dense digital layouts. |

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 |
|---|---|---|---|
| SN74LVC2G125DBVR | TSSOP8 (SOT505-2) package; 3.1 mm body width vs. 2.3 mm; thermal resistance RθJA = 210 K/W vs. 230 K/W. | Better heat dissipation at full drive but occupies 30% more board area; less suitable for ultra-dense portable designs. | Select when thermal margin > 15 °C is required at 24 mA continuous load per channel. |
| 74LVC2G126DC,125 | Inverting output logic (vs. non-inverting); identical pinout, specs, and package; same marking code V25. | Requires logic inversion in upstream signal path; unsuitable where polarity-critical timing (e.g., clock enable) is used. | Choose only when system-level logic requires inverted enable behavior and layout reuse of VSSOP8 footprint is mandatory. |
Compared with SN74LVC2G125DBVR, the 74LVC2G125DC,125 saves PCB area in space-constrained applications but trades 10 K/W higher thermal resistance; versus 74LVC2G126DC,125, it preserves signal polarity critical for synchronous bus handshaking without redesigning control logic.

FAQ
Does 74LVC2G125DC,125 support hot-swap insertion?
Yes. Its IOFF circuitry actively disables outputs and blocks backflow current when VCC = 0 V, allowing safe insertion into live backplanes or modular systems without disrupting upstream logic. This behavior is verified per JEDEC JESD78 and confirmed in Section 1 of the datasheet under "partial power down applications."
Can inputs exceed VCC without damage?
Yes. Inputs tolerate voltages up to 5.5 V regardless of VCC setting (1.65–5.5 V), enabling direct connection to 5 V TTL outputs while powered from 1.8 V or 2.5 V rails. This is specified in Table 6 (Recommended Operating Conditions) and Table 5 (Limiting Values) of the datasheet.
What is the maximum capacitive load this device can drive?
The device drives up to 50 pF load capacitance while maintaining guaranteed propagation delay (tpd ≤ 5.5 ns at VCC = 3.3 V) and output voltage swing (VOL ≤ 0.8 V, VOH ≥ 2.0 V). This is validated in Table 10 test conditions and Figure 5 test circuit with CL = 50 pF and RL = 500 Ω.
Is the VSSOP8 package RoHS and REACH compliant?
Yes. The SOT765-1 (VSSOP8) package for 74LVC2G125DC,125 meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free matte tin terminal finish and halogen-free molding compound, as documented in Nexperia's Material Declaration (MD-000123 rev. 19).
