Product details
Overview
74LVC1G125GV,125 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. It provides ±24 mA output drive at 3.0 V, supports partial power-down via IOFF circuitry, and operates across –40 °C to +125 °C. Used in mixed-voltage I/O interfacing on microcontroller peripheral buses.
For engineers reviewing the 74LVC1G125GV,125 datasheet, 74LVC1G125GV,125 pinout, 74LVC1G125GV,125 application, or 74LVC1G125GV,125 equivalent, this device serves as a compact, low-power unidirectional buffer for voltage-level bridging, high-noise immunity signal routing, and controlled bus isolation in space-constrained embedded systems.
Technical Context
This IC implements a single non-inverting buffer with active-low 3-state output enable (OE), enabling bidirectional bus control when paired with complementary devices. Its Schmitt-trigger inputs tolerate slow-rising signals and reject noise up to ±0.3 V hysteresis depending on VCC.
The IOFF feature disables output leakage during partial power-down by disconnecting internal paths when VCC = 0 V, limiting backflow current to ±2 μA. Input overvoltage tolerance extends to 5.5 V regardless of supply voltage, allowing safe interfacing with 5 V TTL sources 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 operation across 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 15 pF loads with <6 ns propagation delay, supporting moderate-speed digital interconnects. |
| Propagation Delay (A→Y) | 0.5 ns (min) to 4.5 ns (max) at VCC = 3.0–3.6 V - Ensures timing predictability in sub-100 MHz data paths with tight skew budgets. |
| IOFF Leakage Current | ±2 μA at VCC = 0 V - Prevents damaging back-current flow during hot-swap or partial system power-down sequences. |
| Input Hysteresis | Typ. 0.3 V to 0.8 V (VCC-dependent) - Rejects noise on slow-switching lines such as reset, enable, or status signals. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Meets industrial-grade robustness requirements without external protection components. |
| Operating Temperature | –40 °C to +125 °C - Qualified for under-hood automotive, industrial motor control, and extended-range power supply monitoring. |
Pinout & Package
74LVC1G125GV,125 uses the SC-74A (SOT753) package: plastic surface-mounted, 5-lead, body size 3.1 mm × 1.7 mm × 1.3 mm, with gull-wing leads and pin 1 indicator below marking code 'V25'.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OE | Active-low output enable | Drives Y to high-impedance when HIGH; enables buffered A→Y pass-through when LOW. Compatible with open-drain control logic. |
| 2 - A | Data input | Schmitt-triggered input accepts 0–5.5 V regardless of VCC; immune to ringing and slow edges on PCB traces. |
| 3 - GND | Ground reference | 0 V return path for all internal logic and output stages; must be low-inductance connection to minimize switching noise. |
| 4 - Y | 3-state output | Non-inverting buffered output capable of sourcing/sinking ±24 mA; enters high-Z state within 5.5 ns of OE assertion. |
| 5 - VCC | Power supply | Single-supply rail powering both input and output stages; IOFF remains functional even if VCC drops to 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (1.65–5.5 V) | Eliminates need for external level translators in mixed-voltage systems such as FPGA-to-sensor or MCU-to-legacy-peripheral interfaces. |
| Overvoltage-tolerant inputs (to 5.5 V) | Allows direct connection to 5 V TTL outputs while operating from 1.8 V or 2.5 V supplies-no series resistors or clamps required. |
| IOFF partial power-down support | Prevents back-driving of powered-down sections in modular systems, satisfying I²C-bus and PCIe hot-plug safety requirements. |
| Schmitt-trigger inputs | Provides 300–800 mV hysteresis to suppress false triggering from EMI, crosstalk, or long trace reflections in noisy industrial environments. |
| Low dynamic power (CPD = 25 pF) | Reduces switching current in high-frequency enable/disable cycling, critical for battery-powered IoT node wake-up signaling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bus buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G125DBVR | TI part in SOT-23-5 (same pinout); identical VCC range and IOFF, but lower max output drive (±24 mA same), slightly higher ICC (5 μA vs 4 μA). | Approved for automotive AEC-Q100 Grade 1; preferred where qualification documentation is mandatory. | Select for automotive production requiring TI's PPAP package and long-term supply assurance. |
| 74AUP1G125GW,125 | Nexperia AUP variant in TSSOP5; lower static current (0.9 μA vs 4 μA), wider temp range (–40 °C to +125 °C same), but narrower VCC (0.8–3.6 V). | Better suited for ultra-low-power always-on sensor nodes where VCC ≤ 3.3 V and sleep current dominates. | Choose when system VCC is fixed at 1.8 V or 3.3 V and sub-1 μA quiescent current is critical. |

FAQ
Can 74LVC1G125GV,125 operate with VCC = 1.65 V while accepting 5 V inputs?
Yes. Its inputs are overvoltage tolerant up to 5.5 V independent of VCC, verified per datasheet Table 6 and Section 1. This allows safe interfacing with 5 V TTL outputs while powered from 1.65 V rails-no external clamping diodes or resistors needed.
What is the maximum capacitive load the output can drive at 3.3 V supply?
At VCC = 3.3 V, the output maintains guaranteed VOL ≤ 0.55 V and VOH ≥ 2.7 V while sourcing/sinking ±24 mA, supporting typical loads up to 50 pF with <4.5 ns propagation delay (Table 8). For heavier loads (>70 pF), derate VCC or add series termination.
Does the IOFF feature work when VCC is disconnected but OE and A remain biased?
Yes. IOFF activates when VCC = 0 V, disabling internal conduction paths. Output leakage remains ≤±2 μA even if OE or A are held at 5.5 V (Table 7), preventing back-current into unpowered subsystems-a key requirement for hot-swap and modular power architectures.
Is the SC-74A (SOT753) package compatible with standard reflow profiles for lead-free assembly?
Yes. The SOT753 package is qualified for JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C and time above liquidus ≤60 seconds. Thermal resistance (RθJA) is 220 K/W, requiring minimal copper pour for +125 °C ambient operation.
