Product details

Overview

74HCT4002D-Q100 from Nexperia is a dual 4-input NOR gate IC qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C), featuring TTL-compatible input levels, 4.5 V to 5.5 V supply operation, 33 ns max propagation delay at 125 °C, and SO14 plastic small outline package. It serves as a logic-level combinatorial gate in automotive body control modules for signal arbitration and fault-condition detection.

For engineers reviewing the 74HCT4002D-Q100 datasheet, 74HCT4002D-Q100 pinout, 74HCT4002D-Q100 application, or 74HCT4002D-Q100 equivalent, key selection criteria include automotive temperature compliance, TTL input threshold compatibility, output drive strength (4.0 mA sink/source), SO14 footprint constraints, and NOR logic function mapping in safety-critical subsystems.

Technical Context

This device implements two independent 4-input NOR gates with CMOS output stages and input clamp diodes enabling overvoltage-tolerant interfacing via current-limiting resistors. Each gate exhibits identical truth table behavior: output HIGH only when all four inputs are LOW.

Logic operation follows standard Boolean NOR: Y = NOT(A OR B OR C OR D). Input thresholds are fixed at 2.0 V (VIH min) and 0.8 V (VIL max) across −40 °C to +125 °C, ensuring robust noise margin in electrically noisy automotive environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Dual 4-input NOR gate - provides two independent combinatorial logic blocks for signal merging or active-low enable logic.
Supply Voltage Range	4.5 V to 5.5 V - matches standard automotive 5 V rail with ±10% tolerance; not rated below 4.5 V.
Propagation Delay	33 ns max at VCC = 4.5 V, T = 125 °C, CL = 50 pF - defines worst-case timing budget for synchronous control paths.
Output Drive	±4.0 mA at VOH/VOL - supports direct interface to standard TTL loads without external buffering.
Input Thresholds	VIH ≥ 2.0 V, VIL ≤ 0.8 V - ensures reliable recognition of TTL-level signals across full temperature range.
ESD Protection	HBM > 2000 V, MM > 200 V - meets automotive ESD immunity requirements per AEC-Q100.
Operating Temperature	−40 °C to +125 °C - qualified for under-hood and powertrain applications per AEC-Q100 Grade 1.

Pinout & Package

74HCT4002D-Q100 uses the SO14 plastic small outline package (SOT108-1), 14-lead, 3.9 mm body width, with 1.27 mm lead pitch and gull-wing surface-mount terminals.

Pin/Terminal	Circuit Role	Design Meaning
1A, 1B, 1C, 1D	Gate 1 inputs	Four independent logic inputs for first NOR gate; accept TTL-level signals with internal clamping diodes.
1Y	Gate 1 output	Active-low open-drain–compatible CMOS output capable of sourcing/sinking 4.0 mA.
2A, 2B, 2C, 2D	Gate 2 inputs	Four independent logic inputs for second NOR gate; electrically isolated from Gate 1.
2Y	Gate 2 output	Independent CMOS output with identical drive and voltage specs as 1Y.
VCC	Positive supply	Single 4.5–5.5 V supply pin; powers both gates and internal circuitry.
GND	Ground reference	0 V return path for all logic and power currents; must be low-impedance for noise immunity.
6, 8	No-connect	Internally unconnected pins; must remain floating - no external connection or pull-up/down.

Key Features

Feature	Design Value
AEC-Q100 Grade 1 qualification	Validated for automotive use from −40 °C to +125 °C with full reliability testing including HTOL, TC, and ESD.
TTL-compatible input thresholds	VIH ≥ 2.0 V and VIL ≤ 0.8 V ensure interoperability with legacy 5 V microcontrollers and sensors without level-shifting.
Input clamp diodes	Enable safe interface to voltages exceeding VCC using external current-limiting resistors - critical for mixed-voltage subsystems.
Low quiescent current	ICC ≤ 40 μA at 5.5 V and 125 °C - minimizes standby power in always-on vehicle modules.

Applications

Body Control Module Logic

Powertrain Sensor Interface

Use Scenario: Combining door lock status, window position, and ignition state to generate centralized fault alerts.

IC Role / Device Role / Timing Role: Dual NOR gate performs real-time logical OR-inversion of four sensor inputs per channel to detect any active fault condition.

Use Value: Eliminates need for discrete logic or microcontroller GPIO expansion in cost-sensitive BCM designs while maintaining AEC-Q100 compliance.

Use Scenario: Validating crankshaft and camshaft position sensor synchronization before engine start.

IC Role / Device Role / Timing Role: NOR gate acts as a hardware-level sensor mismatch detector - output goes HIGH only when both sensors report invalid states simultaneously.

Use Value: Provides fail-safe, zero-latency validation independent of ECU firmware, meeting ASIL-B functional safety decomposition requirements.

LED Driver Enable Control

Diagnostic Communication Arbiter

Use Scenario: Enabling high-brightness LED clusters in adaptive front lighting systems based on ambient light, speed, and steering angle inputs.

IC Role / Device Role / Timing Role: NOR gate combines four enable conditions (all LOW to activate); output drives LED driver enable pin directly.

Use Value: Delivers deterministic, glitch-free activation with sub-35 ns propagation - avoids visible LED flicker during rapid state transitions.

Use Scenario: Managing priority access to CAN diagnostic bus among multiple ECUs during service mode.

IC Role / Device Role / Timing Role: NOR gate implements hardware-based bus grant arbitration: outputs LOW only when all request lines are inactive.

Use Value: Prevents bus contention without software coordination, reducing diagnostic boot time and eliminating race conditions in multi-ECU architectures.

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
SN74HCT4002DR	Same logic function and TTL input thresholds; rated −40 °C to +85 °C only; SO14 package; TI's manufacturing process.	Not AEC-Q100 qualified; unsuitable for under-hood or powertrain locations requiring Grade 1 temperature range.	Select only for non-automotive industrial or consumer applications where extended temperature is not required.
74HCT4002PW-Q100	Identical electrical specs and AEC-Q100 Grade 1 rating; uses TSSOP14 (SOT402-1) package with 4.4 mm body width and 0.65 mm pitch.	Smaller PCB footprint and improved thermal resistance; requires finer-pitch reflow profile and tighter layout tolerances.	Prefer for space-constrained modules where board area savings justify TSSOP assembly complexity.

Compared with SN74HCT4002DR, 74HCT4002D-Q100 delivers guaranteed operation up to +125 °C and formal automotive qualification; versus 74HCT4002PW-Q100, it trades board area for easier manufacturability and higher thermal mass in SO14 form factor.

FAQ

Is 74HCT4002D-Q100 pin-compatible with standard 74HCT4002 devices?

Yes - it shares identical pinout, electrical characteristics, and logic function with non-automotive 74HCT4002 variants. The "-Q100" suffix denotes AEC-Q100 qualification and extended temperature screening, not physical or functional deviation.

Can 74HCT4002D-Q100 interface directly with 3.3 V microcontrollers?

No - its TTL-compatible inputs require VIH ≥ 2.0 V but are specified only for 4.5–5.5 V VCC operation. Driving from 3.3 V logic may result in marginal or unreliable HIGH recognition; level translation is recommended.

What is the maximum capacitive load this device can drive reliably?

It is characterized up to 50 pF load capacitance with guaranteed 33 ns propagation delay at 125 °C. For loads >50 pF, delay increases linearly and output rise/fall times degrade; derating or buffer staging is advised beyond this limit.

Are pins 6 and 8 internally connected or truly unused?

Pins 6 and 8 are confirmed no-connect (n.c.) per datasheet Table 2. They are not bonded internally and must remain unconnected - no pull-up, pull-down, or routing is permitted to avoid parasitic coupling or mechanical stress.
