Product details
Overview
74HC02D-Q100 from Nexperia is an automotive-qualified quad 2-input NOR gate in SO14 (SOT108-1) package, operating from 2.0 V to 6.0 V supply, with CMOS-level inputs, -40 °C to +125 °C temperature range, and propagation delay as low as 7 ns at VCC = 6.0 V. It serves as a logic-level combinatorial gate in vehicle body control modules, powertrain interface circuits, and ADAS sensor signal conditioning paths.
For engineers reviewing the 74HC02D-Q100 datasheet, 74HC02D-Q100 pinout, 74HC02D-Q100 application, or 74HC02D-Q100 equivalent, this page delivers verified functional identity, validated pin mapping for SO14, confirmed AEC-Q100 Grade 1 qualification, and real-world timing and voltage specifications - all directly traceable to Nexperia's Rev. 5 product data sheet dated 15 February 2024.
Technical Context
This device implements four independent 2-input NOR gates using silicon-gate CMOS technology, with input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Each gate exhibits symmetrical HIGH/LOW output drive capability up to ±25 mA per output under recommended conditions.
It supports dual logic families: the 74HC variant accepts CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V), while its pin-compatible 74HCT counterpart (e.g., 74HCT02D-Q100) accepts TTL-compatible inputs (VIH ≥ 2.0 V at VCC = 4.5–5.5 V), allowing seamless integration into mixed-signal automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NOR gate - provides four independent Boolean OR-NOT operations in one IC |
| Supply Voltage Range | 2.0 V to 6.0 V - enables direct compatibility with 3.3 V and 5 V automotive sub-systems without level shifting |
| Propagation Delay | 7 ns (typ) at VCC = 6.0 V, CL = 50 pF - ensures deterministic timing in safety-critical control loops |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to directly drive LED indicators, small relays, or subsequent logic stages |
| Operating Temperature | -40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and cabin ECU deployment |
| Input Clamp Diodes | Integrated - permits robust interfacing to external signals up to VCC + 0.5 V with series resistors |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - exceeds automotive system-level ESD immunity requirements |
Pinout & Package
Package: SO14 (SOT108-1), plastic small outline, 14-lead, 3.9 mm body width, lead pitch 1.27 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | 1Y, 2Y, 3Y, 4Y | Independent NOR gate outputs - each drives one logic result with rail-to-rail swing |
| 2, 5, 8, 11 | 1A, 2A, 3A, 4A | First input per gate - paired with corresponding B input to form 2-input NOR function |
| 3, 6, 9, 12 | 1B, 2B, 3B, 4B | Second input per gate - completes the two-input operand set for each NOR operation |
| 7 | GND | Ground reference (0 V) - must be connected to system ground plane for stable logic thresholds |
| 14 | VCC | Positive supply - powers all four gates; decoupling capacitor (100 nF) required near pin |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across -40 °C to +125 °C ambient, including lifetime reliability testing |
| Wide VCC range (2.0–6.0 V) | Eliminates need for separate voltage regulators in multi-rail ECUs; supports legacy 5 V and modern 3.3 V domains |
| CMOS-level input thresholds | VIH = 3.15 V (min) at VCC = 4.5 V - ensures noise margin > 1.1 V in 5 V systems |
| Low ICC supply current | Max 40 μA at VCC = 6.0 V, full temperature range - reduces quiescent power in always-on modules |
| Side-wettable flanks not applicable | SO14 package (SOT108-1) lacks side-wettable flanks - AOI requires top-surface solder inspection only |
Applications
| Body Control Module (BCM) | Powertrain Control Interface |
|---|---|
|
Use Scenario: Combining door lock status and ignition key presence signals to enable/disable interior lighting logic. IC Role / Device Role / Timing Role: Combinatorial logic gate performing real-time NOR evaluation of two safety-critical inputs. Use Value: Provides fail-safe behavior: output goes HIGH only when both inputs are LOW - directly enabling relay driver stage with no software latency. |
Use Scenario: Validating dual redundant throttle position sensor outputs before feeding to main MCU. IC Role / Device Role / Timing Role: Hardware-level fault detection gate comparing sensor A and B validity flags. Use Value: Detects simultaneous HIGH on both inputs (indicating potential sensor fault) by forcing output LOW - triggers immediate diagnostic flag within <10 ns. |
| ADAS Camera Power Sequencing | Instrument Cluster Display Enable |
|
Use Scenario: Enabling camera image sensor power only after both power-good and thermal OK signals are asserted. IC Role / Device Role / Timing Role: Gate-level AND-NOT logic (via NOR + inversion) controlling high-side load switch enable line. Use Value: Ensures zero power delivery unless both prerequisites are met - prevents sensor damage during cold boot or overtemperature events. |
Use Scenario: Controlling backlight dimming enable based on ambient light sensor and ignition state. IC Role / Device Role / Timing Role: NOR-based priority encoder that disables display if ignition OFF or light sensor saturated. Use Value: Achieves deterministic hardware-enforced display blanking without MCU intervention - meets ISO 26262 ASIL-B timing constraints. |
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 |
|---|---|---|---|
| 74HCT02D-Q100 | TTL-compatible inputs (VIH ≥ 2.0 V); identical pinout, package, and AEC-Q100 qualification | Required when interfacing with legacy 5 V TTL logic or microcontrollers lacking CMOS-level drive strength | Select when upstream drivers cannot guarantee CMOS VIH thresholds - no layout change needed |
| SN74LV02AQPWRQ1 | TI part; LV family, 2.0–5.5 V supply; slightly higher ICC (max 40 μA vs. 40 μA), same 7 ns tpd at 5 V | Approved for automotive use (Q1 suffix), but rated only to +105 °C - unsuitable for under-hood placement above 105 °C | Use only in cabin modules where ambient ≤ +105 °C; verify PCB footprint compatibility (TSSOP14 vs. SO14) |
Compared with 74HC02D-Q100, the 74HCT02D-Q100 offers identical packaging and automotive qualification but relaxes input voltage requirements for TTL interoperability, while SN74LV02AQPWRQ1 trades extended temperature range for alternate supply flexibility and vendor diversification - both require validation of board-level timing margins and thermal derating.

FAQ
What is the maximum allowable supply voltage for continuous operation?
The absolute maximum supply voltage is +7.0 V, but continuous operation must remain within the recommended range of 2.0 V to 6.0 V. Exceeding 6.0 V risks accelerated parametric drift and violates AEC-Q100 stress test conditions - sustained use above 6.0 V voids automotive qualification compliance.
Can 74HC02D-Q100 drive a 50 pF capacitive load at 10 MHz without signal degradation?
Yes: with CL = 50 pF and VCC = 6.0 V, typical propagation delay is 7 ns and transition time is 6 ns, yielding a usable bandwidth > 50 MHz. Output drive capability (±25 mA) ensures clean edges into 50 pF, provided PCB trace inductance is minimized and local decoupling is implemented.
Does this device support hot insertion or live backplane connection?
No - the 74HC02D-Q100 lacks Ioff (power-off protection) or bus-hold circuitry. Connecting inputs or outputs while VCC is unpowered may forward-bias internal clamp diodes, causing excessive current flow and potential latch-up. Always sequence VCC before applying signals.
How does the input clamp diode affect interfacing with a 12 V sensor signal?
When a 12 V signal is applied through a current-limiting resistor (e.g., 10 kΩ), the internal clamp diode conducts only when VIN exceeds VCC + 0.5 V, limiting input current to ≤20 mA. At VCC = 5 V, this allows safe clamping of 12 V transients - but steady-state 12 V must be reduced via resistor divider to avoid exceeding IIK rating.
