Product details
Overview
74LVC02ABQ-Q100 from Nexperia is an automotive-qualified quad 2-input NOR gate in DHVQFN14 package, operating from 1.2 V to 3.6 V supply, with 5 V tolerant inputs, propagation delay as low as 1.0 ns at 3.0–3.6 V, and AEC-Q100 Grade 1 qualification (−40 °C to +125 °C). It serves as a level-translating logic gate in automotive body control modules requiring mixed-voltage signal conditioning.
For engineers reviewing the 74LVC02ABQ-Q100 datasheet, 74LVC02ABQ-Q100 pinout, 74LVC02ABQ-Q100 application, or 74LVC02ABQ-Q100 equivalent, this page delivers verified pin functions, automotive-grade static/dynamic specs, package-specific thermal and AOI features, and direct substitution guidance for NOR gate selection in safety-critical vehicle subsystems.
Technical Context
This device implements four independent CMOS NOR gates with rail-to-rail input voltage tolerance up to 5.5 V while powered from 1.2–3.6 V, enabling seamless interfacing between legacy 5 V microcontrollers and modern 1.8 V/2.5 V domain controllers. Its logic function strictly follows the truth table: output HIGH only when both inputs are LOW; all other combinations yield LOW.
Designed for automotive environments, it guarantees operation across −40 °C to +125 °C with input leakage < ±20 μA at 3.6 V supply and 5.5 V input, output drive capability of ±24 mA at 3.0 V, and dynamic power dissipation capacitance of 8.5 pF - critical for low-noise, low-EMI engine control unit timing paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NOR: Y = NOT(A OR B), fully independent per gate |
| Supply Voltage Range | 1.2 V to 3.6 V - supports ultra-low-voltage domains (e.g., 1.2 V core logic) while maintaining interoperability |
| Input Voltage Tolerance | −0.5 V to +5.5 V - enables direct connection to 5 V TTL/CMOS without external level shifters |
| Propagation Delay (tpd) | 1.0 ns (min) to 5.5 ns (max) at VCC = 3.0–3.6 V - ensures sub-6 ns timing margin in high-speed control loops |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive use |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive robustness requirements for assembly and field operation |
| Power Dissipation Cap | 500 mW at Tamb ≤ 125 °C (DHVQFN14); derates 9.6 mW/K above 98 °C - enables compact thermal design |
Pinout & Package
DHVQFN14 (SOT762-1) package: 2.5 × 3.0 × 0.85 mm body, side-wettable flanks for automated optical inspection (AOI), thermally enhanced with exposed die pad (non-electrical, optional GND tie).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | 1Y, 2Y, 3Y, 4Y | Independent NOR gate outputs - each capable of sourcing/sinking ±24 mA at 3.0 V |
| 2, 5, 8, 11 | 1A, 2A, 3A, 4A | First input per gate - 5 V tolerant, compatible with legacy 5 V logic families |
| 3, 6, 9, 12 | 1B, 2B, 3B, 4B | Second input per gate - identical electrical specs to A inputs; no internal coupling |
| 7 | GND | Ground reference (0 V) - mandatory connection for stable logic thresholds and noise immunity |
| 14 | VCC | Primary supply pin - must be decoupled locally with 100 nF ceramic capacitor near pin |
Key Features

| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C with full reliability testing (HTOL, TC, ESD, etc.) |
| 5 V tolerant inputs on 1.2–3.6 V supply | Eliminates need for discrete level translators in mixed-voltage clusters (e.g., 5 V sensor interface to 1.8 V MCU) |
| DHVQFN14 with side-wettable flanks | Enables 100% AOI coverage of solder joints - critical for zero-defect automotive manufacturing |
| Low dynamic power (CPD = 8.5 pF) | Reduces switching current demand and system-level EMI in densely packed ECUs |
| JEDEC-compliant I/O standards | Meets JESD8-7A (1.65–1.95 V), JESD8-5A (2.3–2.7 V), and JESD8-C/JESD36 (2.7–3.6 V) |
Applications

|---|---|
|
Use Scenario: Signal arbitration between door lock actuator command lines and central security controller. IC Role / Device Role / Timing Role: NOR gate performs wired-OR logic inversion to resolve conflicting lock/unlock requests with deterministic priority. Use Value: Sub-6 ns propagation ensures real-time response within 10 ms safety-critical window; 5 V tolerance accommodates legacy switch inputs. |
Use Scenario: Combining proximity sensor alerts (5 V open-collector) with camera trigger signals (1.8 V LVCMOS) before feeding to MCU interrupt pin. IC Role / Device Role / Timing Role: Level-translating logic combiner - converts dual-voltage inputs into single-rail active-low interrupt enable. Use Value: Eliminates external voltage translators; guaranteed timing behavior across full automotive temperature range. |
| Engine Control Unit (ECU) Diagnostics | Electric Power Steering (EPS) Motor Control Logic |
|
Use Scenario: Generating fault latch enable signal when multiple diagnostic conditions (e.g., overtemp + overcurrent) occur simultaneously. IC Role / Device Role / Timing Role: NOR-based combinational logic block implementing "NOT (A OR B)" to assert latched fault flag only when both faults are absent. Use Value: Deterministic fail-safe behavior with < 10 ns skew between gates; AEC-Q100 qualification ensures long-term reliability under vibration/thermal cycling. |
Use Scenario: Synchronizing torque request validation and motor phase enable signals prior to H-bridge activation. IC Role / Device Role / Timing Role: Safety interlock gate - prevents motor drive unless both torque validity and phase readiness are confirmed. Use Value: 24 mA output drive directly interfaces with optocoupler inputs; side-wettable flanks ensure solder joint integrity in high-vibration EPS assemblies. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC02APWR | Industrial grade (−40 °C to +85 °C), TSSOP14 package, no AEC-Q100 qualification | Not suitable for under-hood automotive use; lacks side-wettable flanks and extended temp rating | Select only for non-automotive industrial control where cost is prioritized over qualification and AOI support |
| 74LVC02ADR | Automotive grade (AEC-Q100 Grade 1), SO14 package, same electrical specs but larger footprint and lower thermal performance | Compatible in logic function but requires PCB redesign; lacks AOI capability and has higher thermal resistance (10.1 mW/K derating above 100 °C) | Choose when legacy SOIC layout reuse is required and thermal headroom exceeds 150 mW |
Compared with SN74LVC02APWR and 74LVC02ADR, the 74LVC02ABQ-Q100 uniquely combines AEC-Q100 Grade 1 qualification, DHVQFN14's AOI-enabled manufacturability, and best-in-class thermal derating (9.6 mW/K above 98 °C), making it the only option qualified for next-generation compact, high-reliability automotive logic nodes.

FAQ
Is the exposed thermal pad on the DHVQFN14 package electrically connected?
No. The exposed pad (terminal 1 index area) is not electrically connected to any internal node. Per datasheet note, it may remain floating or be tied to GND - no electrical requirement exists for soldering it, though thermal performance improves if connected to a GND plane via thermal vias.
Can 74LVC02ABQ-Q100 drive a 50 pF load at 3.3 V while maintaining AEC-Q100 timing specs?
Yes. At VCC = 3.3 V and CL = 50 pF, the maximum propagation delay remains 5.5 ns (per Table 7), fully within AEC-Q100 validated limits. The device's 24 mA drive strength and 8.5 pF CPD ensure stable operation under these conditions across −40 °C to +125 °C.
What is the minimum supply voltage for guaranteed logic operation at +125 °C?
The minimum functional supply voltage is 1.2 V across the full −40 °C to +125 °C range, as specified in Table 5. Below 1.2 V, VIH/VIL thresholds degrade and propagation delay increases beyond guaranteed limits - no operation is assured below this value at max temperature.
Does the 5 V input tolerance apply to all pins, including VCC and GND?
No. The 5 V tolerance applies exclusively to input pins (1A–4B). VCC must remain within 1.2–3.6 V; applying >3.6 V to VCC violates absolute maximum ratings and risks permanent damage. GND must be held at 0 V - negative voltages below −0.5 V are prohibited per Table 4.
