Product details
Overview
74LVC1G38GV,125 from Nexperia is a single 2-input NAND gate with open-drain output, designed for level translation between 3.3 V and 5 V logic domains. It features Schmitt-trigger inputs for noise immunity, IOFF partial power-down protection, and operates across 1.65 V to 5.5 V supply. Used in I²C bus pull-up control, GPIO expansion interfaces, and mixed-voltage sensor signal conditioning.
For engineers reviewing the 74LVC1G38GV,125 datasheet, 74LVC1G38GV,125 pinout, 74LVC1G38GV,125 application, or 74LVC1G38GV,125 equivalent, this device serves as a robust, low-power logic translator in space-constrained industrial and automotive-adjacent embedded systems where voltage domain bridging and bus arbitration are required.
Technical Context
The 74LVC1G38GV implements standard NAND logic with open-drain output, requiring an external pull-up resistor to define HIGH-level voltage and current sourcing capability. Its Schmitt-trigger inputs accept slow-rising signals (≤10 ns/V transition rate at VCC ≥ 2.7 V) and tolerate input voltages up to 5.5 V regardless of VCC.
IOFF circuitry actively disables the output when VCC = 0 V, blocking backflow current during partial power-down-critical for hot-swap and multi-rail system integrity. The device complies with JEDEC standards JESD8-7, JESD8-5, and JESD8-B/JESD36 across its full 1.65–5.5 V operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 2-input NAND with open-drain output - enables wired-AND bus structures and I²C-compatible bidirectional signaling. |
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V on A/B pins - allows 5 V inputs even when VCC = 1.65 V, enabling reliable mixed-voltage translation. |
| Output Drive (VCC = 3.0 V) | ±24 mA sink capability - sufficient to drive 10 kΩ pull-ups at 3.3 V while maintaining VOL ≤ 0.55 V under load. |
| Propagation Delay | 0.5–5.7 ns (VCC = 3.0–3.6 V) - ensures sub-6 ns timing for high-speed digital control paths in real-time systems. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood, industrial PLC, and extended-temperature embedded applications. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets IEC 61000-4-2 Level 2 requirements for board-level robustness. |
Pinout & Package
74LVC1G38GV 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 at lower-left corner below marking code "YB".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data Input | First NAND input; accepts 0–5.5 V, Schmitt-triggered for noise margin and slow-edge tolerance. |
| 2 (B) | Data Input | Second NAND input; identical electrical behavior to Pin 1, enabling symmetric dual-input logic control. |
| 3 (GND) | Ground Reference | 0 V return path for all internal logic and output current; must be low-impedance for stable VOL performance. |
| 4 (Y) | Open-Drain Output | Active-Low NAND result; requires external pull-up to define HIGH state and current sourcing capability. |
| 5 (VCC) | Supply Voltage | Primary power rail (1.65–5.5 V); powers internal logic and enables IOFF shutdown when de-energized. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 1.65–5.5 V operation enables drop-in use across legacy and modern low-voltage microcontroller I/O banks. |
| 5 V-Tolerant Inputs | Accepts 5 V signals at A/B pins with VCC as low as 1.65 V - eliminates need for discrete level-shifting components. |
| IOFF Partial Power-Down | Disables Y output when VCC = 0 V, preventing destructive back-current in multi-rail systems during sequencing faults. |
| Schmitt-Trigger Inputs | Provides ≥0.5 V hysteresis (typ.) - rejects noise on long traces or noisy sensor lines without external RC filtering. |
| High Sink Current | 24 mA @ VCC = 3.0 V - drives standard 10 kΩ I²C pull-ups at 400 kHz while maintaining VOL ≤ 0.55 V. |
Applications
| Industrial Sensor Interface | I²C Bus Arbitration |
|---|---|
|
Use Scenario: Connecting 5 V analog sensor outputs to a 3.3 V microcontroller ADC monitoring circuit with shared interrupt line. IC Role / Device Role / Timing Role: NAND gate configured as active-low OR function to combine multiple sensor fault flags onto one MCU input. Use Value: Eliminates need for discrete diodes or additional logic; Schmitt inputs reject EMI from motor-driven sensors. |
Use Scenario: Enabling multi-master arbitration on a 3.3 V I²C bus where one master operates at 5 V logic levels. IC Role / Device Role / Timing Role: Open-drain output acts as voltage-translating bus driver, ensuring compatible LOW-level signaling across rails. Use Value: Maintains I²C compliance (VOL ≤ 0.4 V) while supporting 5 V masters without bus contention or damage. |
| GPIO Expansion Logic | Power Sequencing Control |
|
Use Scenario: Adding programmable enable logic for peripheral modules using limited MCU GPIOs. IC Role / Device Role / Timing Role: NAND gate combines two MCU-controlled signals to generate a synchronized enable pulse for a DC-DC converter. Use Value: Reduces firmware complexity by offloading combinatorial logic; IOFF prevents leakage during MCU reset. |
Use Scenario: Coordinating startup sequence of FPGA, memory, and analog subsystems in a multi-rail power architecture. IC Role / Device Role / Timing Role: NAND gate monitors READY signals from two regulators and gates power-on reset to downstream ICs. Use Value: Ensures strict sequencing order; open-drain output interfaces cleanly with multiple reset controllers sharing same net. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G00GV,125 | Push-pull (not open-drain) output; no IOFF; identical supply range and speed. | Cannot be used in wired-AND or I²C configurations; unsuitable for partial power-down systems. | Select only when push-pull drive is required and bus sharing is not needed. |
| SN74LVC1G38DBVR | Same logic function and open-drain output; TI part in SOT-23-5 (same pinout), but lacks IOFF and Schmitt inputs. | Higher VOL at 3.3 V (0.7 V vs. 0.55 V); no guaranteed operation below −40 °C or above +85 °C. | Choose only for cost-sensitive non-automotive designs where extended temperature and IOFF are not required. |
Compared with 74LVC1G00GV,125 and SN74LVC1G38DBVR, the 74LVC1G38GV,125 uniquely combines open-drain output, IOFF, Schmitt inputs, and full −40 °C to +125 °C qualification-making it the sole option for robust, mixed-voltage, hot-swap-capable logic interfacing.

FAQ
Can 74LVC1G38GV,125 be used as a level shifter between 1.8 V and 5 V domains?
Yes - its 5 V-tolerant inputs accept 5 V signals while operating at VCC = 1.8 V, and its open-drain output can be pulled up to 5 V. This enables bidirectional level translation when combined with appropriate pull-up resistors and bus topology design, per Figure 10 in the official Nexperia application note AN10955.
What is the maximum recommended pull-up resistor value for I²C operation at 400 kHz?
At VCC = 3.3 V and Tamb = 25 °C, the maximum pull-up is 10 kΩ to ensure VOL ≤ 0.4 V with 3 mA sink current. For worst-case conditions (Tamb = +125 °C, VCC = 1.65 V), 4.7 kΩ is recommended to maintain timing margins and noise immunity per I²C specification UM10204.
Does the IOFF feature require external circuitry to function?
No - IOFF is fully internal and activates automatically when VCC drops below ~0.8 V. No external enable/disable signal or biasing is needed; the output transitions to high-impedance state within nanoseconds of VCC collapse, preventing back-current flow into powered-down sections.
Is the SC-74A (SOT753) package RoHS-compliant and lead-free?
Yes - the 74LVC1G38GV,125 is manufactured in a lead-free, halogen-free, RoHS-compliant process. The SOT753 package meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and is compatible with standard reflow profiles up to 260 °C peak temperature.
