Product details
Overview
74LVC1G02GW-Q100 from Nexperia is a single 2-input automotive-grade NOR gate logic IC with Schmitt-trigger inputs, 1.65 V to 5.5 V supply range, ±24 mA output drive at 3.0 V, IOFF-enabled partial power-down protection, and AEC-Q100 Grade 1 qualification for under-hood control modules.
For engineers reviewing the 74LVC1G02GW-Q100 datasheet, 74LVC1G02GW-Q100 pinout, 74LVC1G02GW-Q100 application, or 74LVC1G02GW-Q100 equivalent, key selection criteria include mixed-voltage translation capability (3.3 V/5 V), guaranteed operation up to +125 °C, IOFF leakage < ±2 μA at VCC = 0 V, and TSSOP5 package compatibility with high-density PCB layouts.
Technical Context
This device implements a standard NOR Boolean function (Y = NOT(A OR B)) with Schmitt-trigger inputs enabling robust noise immunity against slow-rising signals in automotive sensor interfaces. Its IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0 V.
It supports dual-supply translation: inputs tolerate up to 5.5 V independent of VCC, allowing direct interfacing between 5 V legacy sensors and 3.3 V microcontrollers. Propagation delay ranges from 0.5 ns (VCC = 5.5 V) to 10.5 ns (VCC = 1.65 V) across -40 °C to +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input NOR gate (Y = NOT(A OR B)) |
| 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 systems |
| Input Voltage Tolerance | Up to 5.5 V - allows 5 V signal input while VCC = 3.3 V for level translation |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple LVC inputs or small LEDs directly |
| IOFF Leakage Current | < ±2 μA at VCC = 0 V - prevents damaging backfeed current during hot-swap or partial power-down |
| Propagation Delay | 0.5 ns to 10.5 ns - varies with VCC and temperature; 2.1 ns typical at VCC = 3.3 V, 25 °C |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine control, body electronics |
Pinout & Package
TSSOP5 plastic thin shrink small outline package (SOT353-1); 5 leads; body width 1.25 mm; pin 1 index located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Data input | Second NOR input; Schmitt-triggered for noise immunity on slow edges |
| 2 (A) | Data input | Primary NOR input; compatible with TTL, CMOS, and 5 V logic levels |
| 3 (GND) | Ground reference | 0 V return path; must be low-impedance for stable switching and ESD discharge |
| 4 (Y) | Data output | Inverted NOR result; rail-to-rail CMOS output capable of sourcing/sinking ±24 mA |
| 5 (VCC) | Supply voltage | Power rail; IOFF circuit monitors this pin to disable outputs during power loss |
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 |
| Schmitt-trigger inputs | Hysteresis ≥ 0.3 V at VCC = 3.3 V - rejects noise on long traces or inductive sensor lines |
| IOFF partial power-down | Outputs go high-impedance when VCC = 0 V - eliminates back-current paths in multi-rail systems |
| Overvoltage-tolerant inputs | Inputs withstand 5.5 V regardless of VCC - enables safe interface with 5 V sensors feeding 3.3 V MCUs |
| ESD robustness | HBM > 2000 V, CDM > 1000 V - meets automotive board-level ESD requirements without external protection |
Applications
| Engine Control Unit (ECU) Sensor Interface | Body Control Module (BCM) Signal Conditioning |
|---|---|
Use Scenario: Combining two analog sensor fault flags (e.g., coolant temp and oil pressure) into a single diagnostic alert line. IC Role / Device Role / Timing Role: Logic-level NOR gate performing active-low fault aggregation before MCU interrupt input. Use Value: Reduces MCU GPIO count; Schmitt inputs reject EMI from nearby ignition coils; IOFF prevents fault line corruption during ECU sleep mode. |
Use Scenario: Debouncing door lock/unlock switch signals before routing to CAN transceiver enable control. IC Role / Device Role / Timing Role: Input conditioning and logic inversion for mechanical switch inputs with slow bounce characteristics. Use Value: Eliminates need for external RC filters; wide VCC range supports 12 V battery-sensed 5 V rails; AEC-Q100 ensures reliability over 15-year vehicle life. |
| ADAS Camera Power Sequencing | Infotainment System Reset Coordination |
Use Scenario: Generating camera module power-on reset pulse by NOR-ing two delayed enable signals. IC Role / Device Role / Timing Role: Timing combinatorial logic element synchronizing power rails and clock domains during cold start. Use Value: Ensures strict power-up sequence compliance; propagation delay variation ≤ ±1.5 ns across temperature avoids metastability in image pipeline startup. |
Use Scenario: Coordinating system-wide reset assertion across infotainment SoC, audio codec, and display controller after brown-out detection. IC Role / Device Role / Timing Role: Glue logic for synchronized reset generation with fail-safe deassertion timing. Use Value: Prevents partial initialization states; overvoltage-tolerant inputs accept 5 V brown-out detector output while VCC = 3.3 V; latch-up immunity > 250 mA protects against transient coupling. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC1G02GV-Q100 | Same logic function and specs; SC-74A (SOT753) package instead of TSSOP5 | 0.95 mm body width vs. 1.25 mm - better suited for ultra-dense layouts where height clearance is constrained | Select when footprint area is prioritized over hand-solderability or thermal performance |
| 74LVC1G02GZ-Q100 | Same logic function and specs; XSON5 (SOT8065-1) package with side-wettable flanks | No leads, 1.1 × 0.85 mm body - optimized for automated optical inspection (AOI) and reflow yield in high-volume SMT lines | Select for automotive Tier 1 production requiring IPC-A-610 Class 3 compliance and solder joint inspection |
Compared with 74LVC1G02GV-Q100 and 74LVC1G02GZ-Q100, the 74LVC1G02GW-Q100 offers superior thermal dissipation (3.3 mW/K derating above 74 °C) and manual rework accessibility due to gull-wing leads, making it preferred for prototyping and under-hood modules requiring field serviceability.

FAQ
Can 74LVC1G02GW-Q100 interface a 5 V sensor output with a 3.3 V microcontroller?
Yes. Its inputs tolerate up to 5.5 V regardless of VCC, enabling direct connection of 5 V sensor outputs to the A or B pins while VCC = 3.3 V. The output swings rail-to-rail between GND and 3.3 V, safely driving the MCU's 3.3 V logic inputs without external level shifters.
What happens to the output during power-down (VCC = 0 V)?
When VCC drops to 0 V, the integrated IOFF circuit forces the Y output into a high-impedance state, limiting leakage current to < ±2 μA. This prevents backflow current from other powered rails through the device, protecting downstream circuitry in partial-power-down architectures.
Is the Schmitt-trigger input hysteresis specified across temperature?
Yes. Hysteresis is maintained across -40 °C to +125 °C, with typical values ≥ 0.3 V at VCC = 3.3 V. This ensures consistent noise rejection on slow-rising signals (e.g., thermistor-based sensor outputs) throughout the full automotive operating range.
How does its propagation delay compare to standard LVC gates at 1.8 V?
At VCC = 1.8 V and +25 °C, tpd is 3.2 ns (typical), matching industry-standard LVC performance. At -40 °C to +125 °C, max delay increases to 8.0 ns (–40 °C to +85 °C) and 10.5 ns (–40 °C to +125 °C), fully characterized and guaranteed in the datasheet.
