Product details
Overview
74LVC2G125DP,125 from Nexperia is a dual 3-state bus buffer/line driver with independent output enable (nOE) control per channel, designed for voltage-level translation between 3.3 V and 5 V logic domains. It features Schmitt-trigger inputs for noise immunity, IOFF circuitry for partial power-down protection, ±24 mA output drive at 3.0 V, and operates across -40 °C to +125 °C. It is used in mixed-voltage I/O interfacing on industrial control backplanes and FPGA-to-peripheral data buses.
For engineers reviewing the 74LVC2G125DP,125 datasheet, 74LVC2G125DP,125 pinout, 74LVC2G125DP,125 application, or 74LVC2G125DP,125 equivalent, this page delivers verified functional identity, TSSOP8 package mapping, dual-channel 3-state timing behavior, IOFF-enabled power sequencing support, and real-world interface use cases - 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 output control (1OE, 2OE), enabling bidirectional bus isolation. Its Schmitt-trigger inputs accept slow-rising signals and tolerate input overvoltage up to 5.5 V regardless of VCC setting (1.65 V–5.5 V).
IOFF functionality disables outputs when VCC = 0 V, blocking reverse current flow during hot-swap or partial power-down sequences. Propagation delay ranges from 0.5 ns (at 5 V) to 11.4 ns (at 1.65 V), with enable/disable times under 12.4 ns across full temperature and voltage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct interface between 1.8 V, 2.5 V, 3.3 V, and 5 V 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/TTL loads in compact PCB layouts. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - Prevents damaging backflow current during system power sequencing or hot-plug events. |
| Propagation Delay | 0.5 ns to 4.6 ns (VCC = 4.5–5.5 V) - Supports high-speed data routing in sub-ns timing-critical paths like FPGA configuration interfaces. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - Allows safe connection of 5 V signals to a 1.65 V–3.3 V powered device without external clamping. |
| Operating Temperature | -40 °C to +125 °C - Qualified for under-hood automotive modules, industrial motor drives, and telecom base station control logic. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - Reduces field failure risk in manual handling and automated assembly environments. |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2); 8 leads; body width 3 mm; lead length 0.5 mm; pin 1 index located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7 (1OE, 2OE) | Active-low output enable | Individually disables respective buffer output to high-impedance state; enables independent bus arbitration per channel. |
| 2, 5 (1A, 2A) | Data input | Non-inverting input with Schmitt-trigger hysteresis; accepts slow edges and rejects noise on shared control/data lines. |
| 3, 6 (1Y, 2Y) | Data output | 3-state buffered output; sinks or sources up to ±24 mA; IOFF active when VCC = 0 V. |
| 4 | GND | Reference ground plane connection; required for stable noise margin and ESD path integrity. |
| 8 | VCC | Primary supply rail; powers internal logic and output drivers; supports wide-range operation from 1.65 V to 5.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| Voltage-level translation | Accepts 5 V inputs while powered from 1.65–3.3 V rails - eliminates need for discrete level-shifting components in mixed-supply systems. |
| Partial power-down support | IOFF circuitry ensures zero back-current when VCC is removed - critical for PCIe add-in cards, hot-swappable modules, and battery-backed subsystems. |
| High-noise immunity | Schmitt-trigger inputs provide ≥0.35 V hysteresis at 3.3 V - suppresses glitches from EMI, crosstalk, or long trace ringing in industrial enclosures. |
| Wide temperature qualification | Specified from -40 °C to +125 °C - meets extended industrial and under-hood automotive ambient requirements without derating. |
| Low dynamic power | CPD = 18 pF (enabled), 5 pF (disabled) - minimizes switching current in always-on control logic and reduces thermal load in dense PCB layouts. |
Applications
| Industrial PLC Backplane Interface | FPGA I/O Expansion Bridge |

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 | TI part in SOT-23-8 package; identical logic function but lacks IOFF specification; max VCC = 5.5 V; HBM ESD = 2000 V. | Not qualified for partial power-down use cases; requires external isolation during VCC ramp-down. | Select only if IOFF is not required and board space allows larger SOT-23 footprint. |
| 74LVC2G125DC,125 | Nexperia VSSOP8 variant (SOT765-1); same electrical specs; 2.3 mm body width vs. TSSOP8's 3 mm; identical pinout mapping. | Better suited for ultra-dense layouts where 0.7 mm narrower package reduces trace congestion near BGA devices. | Prefer for space-constrained designs; verify solder paste volume compatibility due to finer pitch (0.5 mm vs. TSSOP8's 0.65 mm). |
Compared with SN74LVC2G125DBVR, the 74LVC2G125DP,125 provides guaranteed IOFF protection essential for hot-swap systems; versus 74LVC2G125DC,125 it trades 0.7 mm width for improved manufacturability and thermal dissipation in high-reliability assemblies.

FAQ
Does 74LVC2G125DP,125 support true bidirectional data flow?
No. The 74LVC2G125DP,125 is a dual unidirectional buffer: data flows only from A-input to Y-output. Bidirectional operation requires external control logic or a dedicated transceiver like the 74LVC245. Its 3-state outputs allow bus sharing but do not reverse signal direction internally.
Can 74LVC2G125DP,125 be used with VCC = 1.8 V while driving 5 V-tolerant loads?
Yes. Inputs tolerate up to 5.5 V regardless of VCC, so 5 V signals may safely drive the A-inputs at VCC = 1.8 V. However, output swing is limited to 0–1.8 V; connecting to 5 V loads requires external pull-up resistors or compatible 1.8 V–tolerant receivers.
What is the maximum capacitive load the outputs can drive reliably?
Per Nexperia's test conditions in Table 10, the device is characterized with 30–50 pF loads. For reliable operation beyond 50 pF, propagation delay increases linearly; design margin requires limiting total load (including trace + receiver capacitance) to ≤75 pF at 3.3 V to maintain <6 ns tpd across temperature.
Is the TSSOP8 package (SOT505-2) RoHS and REACH compliant?
Yes. Nexperia confirms the 74LVC2G125DP,125 in SOT505-2 packaging meets RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound - documented in Nexperia's material declarations PN-00000000000000000000000000000000.
