Product details
Overview
74LVC1G38GV-Q100 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 in automotive control modules. It operates from 1.65 V to 5.5 V, features Schmitt-trigger inputs for noise immunity, supports IOFF partial power-down protection, and is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C).
For engineers reviewing the 74LVC1G38GV-Q100 datasheet, 74LVC1G38GV-Q100 pinout, 74LVC1G38GV-Q100 application, or 74LVC1G38GV-Q100 equivalent, key selection criteria include open-drain drive capability (±24 mA at VCC = 3.0 V), 5 V-tolerant inputs, IOFF-enabled backflow prevention during power sequencing, and automotive-grade thermal and ESD robustness.
Technical Context
This device implements a standard NAND logic function with open-drain output, enabling wired-AND configurations and I²C bus compatibility. Its Schmitt-trigger inputs accept slow-rising signals (Δt/ΔV ≤ 20 ns/V at VCC = 1.65–2.7 V) and tolerate input voltages up to 5.5 V regardless of supply voltage.
The IOFF circuit actively disables the output when VCC = 0 V, limiting reverse current to ±2 μA, while static leakage remains ≤ ±1 μA across −40 °C to +125 °C. Propagation delay ranges from 0.5 ns (typical, VCC = 5.5 V) to 12.5 ns (max, −40 °C to +125 °C, VCC = 1.65 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 2-input NAND with open-drain output - enables wired-AND, bus arbitration, and level-shifting without external pull-ups in mixed-voltage systems. |
| 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. |
| Input Voltage Tolerance | Up to 5.5 V on all inputs - allows safe connection to 5 V sources even when VCC = 1.65 V. |
| Output Drive | ±24 mA sink/source at VCC = 3.0 V - sufficient to drive typical I²C bus loads or LED indicators directly. |
| IOFF Leakage | ≤ ±2 μA at VCC = 0 V - prevents damaging backflow current during hot-insertion or partial power-down sequences. |
| Propagation Delay | 0.5–4.9 ns (max) over full temperature and voltage range - ensures timing predictability in high-speed control signal paths. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - meets automotive board-level reliability requirements without additional protection circuitry. |
Pinout & Package
74LVC1G38GV-Q100 uses the SC-74A (SOT753) surface-mount package: 5-terminal plastic package, body size 3.1 mm × 1.7 mm × 1.3 mm, with gull-wing leads and moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data input 1 | Schmitt-triggered input accepting 0–5.5 V; tolerant of slow edges and noise. |
| B | Data input 2 | Identical to Pin A; both inputs fully 5 V tolerant independent of VCC. |
| GND | Ground reference | 0 V return path for logic and power; must be low-impedance for stable switching. |
| Y | Open-drain output | Active-low output requiring external pull-up; supports wired-AND and bidirectional bus operation. |
| VCC | Positive supply | Primary power rail (1.65–5.5 V); powers internal logic and enables IOFF control. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including thermal cycling and humidity testing. |
| IOFF partial power-down protection | Automatically disables output and limits reverse current to ±2 μA when VCC = 0 V - critical for multi-rail system power sequencing. |
| 5 V tolerant inputs | Accepts 0–5.5 V input signals regardless of VCC setting - eliminates need for external level shifters in mixed-voltage designs. |
| Schmitt-trigger inputs | Hysteresis ≥ 0.3 V (typical) improves noise margin and enables reliable operation with slow or noisy control signals. |
| Low dynamic power | CPD = 6 pF - minimizes switching power (PD = CPD × VCC² × fi × N) in battery-sensitive applications like body control modules. |
Applications
| Body Control Module (BCM) | Instrument Cluster Interface |
|---|---|
|
Use Scenario: Signal conditioning for door lock/unlock status feedback from mechanical switches with long harness runs. IC Role / Device Role / Timing Role: Open-drain NAND acts as debounced, noise-immune logic gate driving CAN/LIN transceiver enable lines.

IC Role / Device Role / Timing Role: Configured as inverter (one input tied HIGH) to translate logic levels while maintaining timing integrity. Use Value: 5 V-tolerant inputs accept 5 V PWM signals directly; 24 mA sink capability drives base of PNP transistor without buffer stage. |
| ADAS Camera Power Sequencing | EV Battery Management System (BMS) Fault Signaling |
|
Use Scenario: Enabling camera sensor power rails only after host processor asserts valid configuration signals. IC Role / Device Role / Timing Role: NAND gate combines "power good" and "config ready" signals to generate synchronized enable pulse. Use Value: Propagation delay ≤ 4.9 ns ensures sub-5 ns timing margin for 100 MHz clock domains; open-drain output interfaces cleanly with PMIC enable pins. |
Use Scenario: Aggregating multiple cell monitor IC fault flags into a single wired-AND alert line for BMS microcontroller. IC Role / Device Role / Timing Role: Wired-AND bus node implementing fault OR logic using open-drain outputs and shared pull-up. Use Value: ±24 mA sink strength supports ≥10 nodes on 3.3 V bus; AEC-Q100 qualification guarantees reliability in high-vibration, high-temp battery enclosures. |
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 |
|---|---|---|---|
| SN74LVC1G00DRYR | Same logic function and open-drain output, but not AEC-Q100 qualified; rated only to +85 °C industrial grade. | Lacks automotive temperature and reliability validation - unsuitable for under-hood or safety-critical modules. | Select only for non-automotive consumer or industrial control where cost is prioritized over qualification. |
| 74LVC1G00GV-Q100 | Identical package and qualification, but features push-pull (not open-drain) output - no built-in wired-AND capability. | Cannot replace 74LVC1G38GV-Q100 in I²C, SMBus, or fault-bus applications requiring open-drain topology. | Choose only when active-HIGH push-pull drive is required and bus arbitration is handled elsewhere. |
Compared with SN74LVC1G00DRYR, the 74LVC1G38GV-Q100 adds AEC-Q100 Grade 1 qualification and extended temperature support; compared with 74LVC1G00GV-Q100, it provides essential open-drain functionality for bus interfacing and fault signaling - making it irreplaceable in automotive wired-AND architectures.

FAQ
Can 74LVC1G38GV-Q100 be used as a level shifter between 1.8 V and 5 V domains?
Yes - its 5 V-tolerant inputs accept 0–5.5 V signals regardless of VCC, and its open-drain output can be pulled up to any voltage ≤ 5.5 V. When VCC = 1.8 V, inputs from 5 V sources are safely clamped internally, and Y can drive a 5 V pull-up without damage. This enables bidirectional translation in I²C-like topologies.
What is the maximum sink current supported at 125 °C ambient?
At Tamb = +125 °C and VCC = 3.0 V, the device maintains ≥20 mA sink capability (per datasheet Table 7 VOL test conditions). Derating is not required below the absolute max rating of ±50 mA, and the 24 mA specification is guaranteed over −40 °C to +125 °C per AEC-Q100 test plan.
Does the IOFF feature require external circuitry to function?
No - IOFF is fully internal and automatic. When VCC drops to 0 V, the output enters high-impedance state and leakage is limited to ±2 μA without any enable/disable pin or external biasing. This behavior is verified per JESD78 latch-up and JEDEC JESD22-A114 HBM tests.
How does the Schmitt-trigger input improve noise immunity in automotive environments?
Schmitt-trigger inputs provide ≥0.3 V hysteresis (typical), meaning the rising threshold (VIH) and falling threshold (VIL) differ significantly - e.g., VIH ≈ 2.0 V and VIL ≈ 1.7 V at VCC = 3.3 V. This prevents oscillation on noisy harnesses or slow-switching sensors, eliminating need for external RC filtering in door switch or seat position detection circuits.
