Product details
Overview
74HC4002D-Q100 from Nexperia is a dual 4-input NOR gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0 V to 6.0 V, featuring CMOS low power dissipation, high noise immunity, and input clamp diodes enabling interface to voltages exceeding VCC - used in automotive body control modules for logic-level signal conditioning and fault-tolerant gate combining.
For engineers reviewing the 74HC4002D-Q100 datasheet, 74HC4002D-Q100 pinout, 74HC4002D-Q100 application, or 74HC4002D-Q100 equivalent, key selection criteria include automotive-grade temperature compliance (-40 °C to +125 °C), dual independent 4-input NOR functionality, SO14 package pin compatibility, and input clamping for overvoltage-safe interfacing in vehicle ECU subsystems.
Technical Context
This device implements two independent 4-input NOR gates using standard CMOS technology, each outputting HIGH only when all four inputs are LOW. Its input clamp diodes allow safe connection to signals up to VCC + 0.5 V, supporting robust interfacing with higher-voltage sensors or legacy systems without external protection components.
The logic function follows strict Boolean NOR behavior per gate: Y = NOT(A OR B OR C OR D). Propagation delays range from 9 ns (VCC = 6.0 V, CL = 50 pF) to 150 ns (VCC = 2.0 V), with transition times as low as 6 ns at full supply, enabling reliable operation in timing-critical automotive combinatorial logic paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 4-input NOR gates - enables compact implementation of two separate multi-input negative-OR decisions in one package. |
| Supply Voltage Range | 2.0 V to 6.0 V - supports direct integration into 3.3 V and 5.0 V automotive domains without level-shifting. |
| Operating Temperature | -40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for under-hood and cabin ECU deployment. |
| Propagation Delay (tpd) | 9 ns typical at VCC = 6.0 V, CL = 50 pF - ensures sub-10 ns timing margin for fast-response safety-critical logic decisions. |
| Input Clamp Diodes | Integrated on all inputs - permits use of current-limiting resistors to safely interface with signals up to VCC + 0.5 V, eliminating need for external TVS or diode networks. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - exceeds automotive ESD robustness requirements for assembly and field reliability. |
| Power Dissipation | 500 mW max (SO14), derates linearly above 100 °C - supports sustained operation in thermally constrained engine bay PCB layouts. |
Pinout & Package
74HC4002D-Q100 uses the SOT108-1 (SO14) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1Y, 13 | Output of Gate 1 | Active-low NOR output; sinks/sourcing capability supports direct drive of LED indicators or downstream CMOS inputs. |
| 1A–1D (2–5) | Inputs of Gate 1 | Four independent logic inputs with clamp diodes - allows safe biasing above VCC using series resistors. |
| n.c. (6, 8) | No-connect terminals | Internally unconnected; must remain floating or tied to GND/VCC per board layout best practices - no electrical function. |
| GND (7) | Ground reference | Primary return path for all internal logic and I/O currents; requires low-impedance PCB plane connection. |
| 2A–2D (9–12) | Inputs of Gate 2 | Second set of four clamp-equipped inputs - enables fully independent dual-gate operation without shared signal constraints. |
| VCC (14) | Supply voltage | CMOS core and I/O rail; decoupling capacitor (100 nF) required within 5 mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across -40 °C to +125 °C ambient, including HTOL, TC, and ESD stress testing per JEDEC JESD47. |
| Input clamp diodes | Enables direct interface to 12 V sensor outputs via 10 kΩ current-limiting resistors - eliminates discrete protection components. |
| High noise immunity | VIH ≥ 70% VCC and VIL ≤ 30% VCC across full voltage/temperature range - rejects common-mode transients in noisy vehicle harness environments. |
| Low static current | ICC ≤ 40 μA at VCC = 6.0 V and T = +125 °C - minimizes quiescent power in always-on vehicle modules. |
| CMOS input levels | Compatible with 3.3 V and 5.0 V microcontrollers without level shifters - simplifies mixed-voltage system design. |
Applications
| Body Control Module Logic | Door Lock Actuator Interface |
|---|---|
|
Use Scenario: Combining door open/closed, window position, and key fob status signals to enable/disable power window motor drive. IC Role / Device Role / Timing Role: Dual 4-input NOR gate performs real-time hardware-level arbitration of multiple safety interlock conditions before enabling actuator power path. Use Value: Ensures fail-safe disablement when any interlock condition (e.g., door ajar) is asserted - no software latency or MCU dependency. |
Use Scenario: Validating simultaneous activation of lock/unlock command, door latch state, and ignition status before energizing solenoid coils. IC Role / Device Role / Timing Role: Hardware-based gate combining prevents unintended actuation by requiring coordinated input states across four independent signals. Use Value: Eliminates risk of partial or conflicting commands reaching actuators - critical for meeting ISO 26262 ASIL-B functional safety goals. |
| Engine Bay Sensor Fusion | Dashboard Warning Light Logic |
|
Use Scenario: Aggregating fault flags from O2 sensor heater, knock sensor, and camshaft position sensor to trigger "Check Engine" lamp driver enable. IC Role / Device Role / Timing Role: NOR gate outputs HIGH only when all monitored sensors report normal operation - inverted logic simplifies active-low warning activation. Use Value: Provides deterministic, zero-latency fault detection independent of ECU software execution cycles or interrupt latency. |
Use Scenario: Driving multiple dashboard LEDs (e.g., ABS, Airbag, Brake) using shared current-sinking outputs controlled by combined status signals. IC Role / Device Role / Timing Role: Dual NOR gates generate active-low enable signals for LED drivers based on combinations of CAN message validity, sensor readiness, and power-on self-test results. Use Value: Reduces MCU GPIO count by 8 pins while maintaining independent control of 4 warning functions via hardware logic. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC4002PW-Q100 | Identical logic and specs but in TSSOP14 (SOT402-1) package - 4.4 mm body width, 0.65 mm pitch. | Better suited for high-density PCBs where SO14 footprint is prohibitive; thermal resistance higher than SO14. | Select when board space is constrained and thermal load is moderate; requires requalification of solder profile. |
| SN74HC4002DR | Texas Instruments variant; same pinout and logic, but rated only to +85 °C and not AEC-Q100 qualified. | Limited to non-automotive industrial or consumer applications; lacks automotive reliability validation and extended temperature support. | Acceptable only for cost-sensitive non-automotive designs where Grade 1 qualification and +125 °C operation are unnecessary. |
Compared with 74HC4002PW-Q100, the 74HC4002D-Q100 offers lower thermal resistance and proven manufacturability in wave-soldered automotive assemblies; versus SN74HC4002DR, it delivers certified automotive reliability and extended temperature margin essential for under-hood deployment.

FAQ
Is the 74HC4002D-Q100 pin-compatible with standard 74HC4002 devices?
Yes - the 74HC4002D-Q100 maintains identical pinout, logic function, and DC/AC electrical characteristics as industry-standard 74HC4002 devices in SO14 packages. The Q100 suffix denotes AEC-Q100 qualification and extended temperature grading, with no changes to pin assignment or interface behavior.
Can the input clamp diodes be used to interface with 12 V automotive signals?
Yes - the integrated input clamp diodes allow safe connection to voltages up to VCC + 0.5 V. When VCC = 5.0 V, a 10 kΩ series resistor limits clamp current to <2 mA for 12 V inputs, satisfying the ±20 mA absolute maximum rating and enabling direct interface without external protection components.
What is the maximum output sink/source current per pin?
The 74HC4002D-Q100 supports ±25 mA DC output current per pin under recommended operating conditions. At VCC = 4.5 V, it delivers VOH ≥ 3.7 V at IO = –4.0 mA and VOL ≤ 0.4 V at IO = 4.0 mA, ensuring reliable driving of standard TTL loads and LED indicators without external buffers.
Does this device require external pull-up or pull-down resistors on unused inputs?
No - unused inputs must be tied to VCC or GND to prevent floating states that cause increased power consumption and potential oscillation. The datasheet explicitly prohibits leaving inputs unconnected; clamp diodes do not eliminate the need for defined logic levels on idle pins.
