Product details
Overview
74LVC1G38GW-Q100 from Nexperia is a single 2-input NAND gate with open-drain output, AEC-Q100 Grade 1 qualified for automotive use, operating from 1.65 V to 5.5 V supply, featuring ±24 mA output drive at VCC = 3.0 V and IOFF partial power-down protection. It serves as a level-translating logic interface in mixed-voltage domains such as body control modules and sensor signal conditioning.
For engineers reviewing the 74LVC1G38GW-Q100 datasheet, 74LVC1G38GW-Q100 pinout, 74LVC1G38GW-Q100 application, or 74LVC1G38GW-Q100 equivalent, key selection criteria include open-drain compatibility with external pull-ups, 5 V-tolerant inputs, Schmitt-trigger input hysteresis for noise immunity, and guaranteed operation up to +125 °C ambient.
Technical Context
This device implements a single 2-input NAND function with true open-drain output architecture-no internal pull-up-requiring external termination for HIGH-level assertion. Its IOFF circuit actively disables output leakage during power-down, preventing backflow current when VCC = 0 V.
Schmitt-trigger inputs provide 0.3–0.45 V hysteresis (depending on VCC), enabling robust operation with slow-rising signals from microcontrollers or sensors. Input voltage tolerance extends to 5.5 V regardless of VCC, supporting direct interfacing with legacy 5 V logic in 3.3 V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input NAND with open-drain output - requires external pull-up for wired-AND or I²C-style bus sharing. |
| Supply Voltage Range | 1.65 V to 5.5 V - supports direct integration into 1.8 V, 2.5 V, 3.3 V, and 5 V domains without level shifters. |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - enables safe connection to 5 V drivers while powered from lower voltages. |
| Output Drive Strength | ±24 mA sink capability at VCC = 3.0 V - sufficient to drive LEDs, MOSFET gates, or multiple CMOS inputs. |
| IOFF Leakage Current | ≤ ±2 μA at VCC = 0 V - prevents damaging back-current during hot-swap or partial system power-down. |
| Propagation Delay | 0.5 ns (min) to 4.9 ns (max) across VCC range - ensures timing predictability in high-speed control paths. |
| Operating Temperature | −40 °C to +125 °C - validated for under-hood automotive environments per AEC-Q100 Grade 1. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, 0.65 mm lead pitch, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Data input | First NAND operand; accepts 0–5.5 V, includes Schmitt-trigger hysteresis for noise margin. |
| 2 (B) | Data input | Second NAND operand; identical electrical behavior to Pin 1. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry and output sink current. |
| 4 (Y) | Open-drain output | Active-LOW output only; must be externally pulled up to define HIGH state and bus voltage level. |
| 5 (VCC) | Supply voltage | Primary power rail; powers internal logic and enables IOFF control when active. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive applications requiring −40 °C to +125 °C operation and lifetime reliability in safety-critical ECUs. |
| IOFF partial power-down protection | Automatically disables output stage when VCC = 0 V, eliminating risk of backfeed current in multi-rail systems. |
| 5 V tolerant inputs | Accepts 0–5.5 V input signals regardless of VCC setting - eliminates need for discrete level translators in mixed-voltage designs. |
| Schmitt-trigger inputs | Provides ≥0.3 V hysteresis to reject noise on slow edges from sensors or long PCB traces without external RC filtering. |
| Open-drain output architecture | Enables wired-OR logic, I²C bus compatibility, and flexible voltage translation by selecting external pull-up voltage independently of VCC. |
Applications
| Body Control Module Interface | Automotive Sensor Signal Conditioning |
|---|---|
|
Use Scenario: Interfacing 5 V analog sensor outputs (e.g., temperature, pressure) to a 3.3 V microcontroller GPIO with interrupt capability. IC Role / Device Role / Timing Role: Level-translating NAND gate acting as active-low enable for sensor data latch or wake-up signal generator. Use Value: Eliminates discrete resistor-divider or dedicated level shifter IC while maintaining noise immunity via Schmitt-trigger inputs and IOFF safety during MCU sleep. |
Use Scenario: Driving an LED indicator on a CAN node diagnostic port where logic HIGH must be pulled to 5 V but controller operates at 3.3 V. IC Role / Device Role / Timing Role: Open-drain driver configured as active-low switch controlling LED cathode with 5 V pull-up. Use Value: Provides precise 24 mA sink capability at 3.3 V supply, enabling bright LED illumination without burdening MCU I/O pins or requiring external FET. |
| Door Lock Actuator Control | Power Supply Sequencing Monitor |
|
Use Scenario: Enabling a 12 V door lock solenoid driver IC only when both "unlock request" and "door closed" signals are asserted. IC Role / Device Role / Timing Role: NAND gate combining two safety interlock signals to generate enable pulse for high-side switch driver. Use Value: Delivers sub-5 ns propagation delay and guaranteed operation at +125 °C, ensuring deterministic response in harsh cabin environments. |
Use Scenario: Monitoring sequencing of multiple power rails (e.g., 5 V → 3.3 V → 1.2 V) in ADAS domain controller, asserting fault flag if order violated. IC Role / Device Role / Timing Role: Wired-AND combiner of delayed rail-good signals feeding into system supervisor reset input. Use Value: Open-drain output allows shared fault bus across multiple sequencing monitors; IOFF prevents false asserts during power-up/down transitions. |
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 |
|---|---|---|---|
| 74LVC1G00GW-Q100 | Push-pull (not open-drain) output; no IOFF; same VCC range and AEC-Q100 Grade 1 rating. | Cannot perform wired-OR or I²C bus functions; unsuitable where external pull-up or multi-source bus arbitration is required. | Select only when active-HIGH push-pull drive is needed and no power-down isolation is required. |
| SN74LVC1G38DRYR | Same logic function and open-drain output, but TI version lacks AEC-Q100 qualification and rated only to +85 °C. | Not approved for under-hood automotive use; limited to infotainment or cabin modules with milder thermal profiles. | Use only in non-safety-critical consumer or industrial applications where automotive qualification is not mandated. |
Compared with 74LVC1G38GW-Q100, the 74LVC1G00GW-Q100 offers higher speed but no bus-sharing capability, while the SN74LVC1G38DRYR provides identical logic but lacks automotive-grade thermal and reliability validation-making the Nexperia part uniquely suited for AEC-Q100-compliant designs requiring open-drain flexibility and full temperature coverage.

FAQ
Can 74LVC1G38GW-Q100 be used with a 5 V pull-up while powered from 3.3 V?
Yes. Its 5 V-tolerant inputs and open-drain output allow the Y pin to be pulled up to 5 V independently of VCC. The output will sink current when LOW, reaching ≤0.55 V at 24 mA with VCC = 3.0 V, ensuring clean logic LOW assertion on the 5 V bus.
Does this device support hot insertion or live board replacement?
Yes. The IOFF feature actively disables the output when VCC = 0 V, limiting back-current to ≤±2 μA even if input or output pins are biased before power is applied-meeting requirements for hot-plug capable automotive modules.
What is the minimum recommended pull-up resistance for the open-drain output?
For VCC = 3.3 V and 24 mA sink, a 10 kΩ pull-up to 5 V yields ~0.24 V drop across the resistor, keeping VOL well within specification. Lower values (e.g., 1 kΩ) increase speed but raise power consumption; design must balance rise time, power, and bus loading.
How does Schmitt-trigger input hysteresis improve noise immunity in automotive applications?
With typical hysteresis of 0.3–0.45 V, the input threshold differs for rising (VIH) and falling (VIL) edges-preventing oscillation on noisy or slowly transitioning signals from switches, relays, or unshielded sensor lines common in vehicle harnesses.
