Product details
Overview
74HCT02D-Q100 from Nexperia is an automotive-qualified quad 2-input NOR gate in SO14 (SOT108-1) package, operating from -40 °C to +125 °C with TTL-compatible inputs, 4.5 V–5.5 V supply range, and propagation delay of 11–29 ns at VCC = 4.5 V. It serves as a logic-level combinatorial gate in vehicle body control modules, powertrain interface logic, and infotainment system signal conditioning.
For engineers reviewing the 74HCT02D-Q100 datasheet, 74HCT02D-Q100 pinout, 74HCT02D-Q100 application, or 74HCT02D-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, SO14 thermal performance up to 125 °C ambient, TTL input threshold compatibility with legacy microcontrollers, and verified 4.0 mA output drive capability at VOH ≥ 3.7 V.
Technical Context
This device implements four independent 2-input NOR gates using silicon-gate CMOS technology with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with 5 V microcontroller GPIOs without level translation. Each gate features clamp diodes on all inputs for overvoltage tolerance when used with current-limiting resistors.
It operates across a wide industrial temperature range (-40 °C to +125 °C) and supports dynamic switching into 50 pF loads with guaranteed tpd ≤ 29 ns and tt ≤ 22 ns at VCC = 4.5 V, while maintaining ICC ≤ 40 μA at VCC = 5.5 V under static conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NOR gate - provides four independent OR-NOT logic operations per package |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard 5 V automotive rail with ±10% tolerance margin |
| Input Threshold Type | TTL-compatible - VIH ≥ 2.0 V, VIL ≤ 0.8 V enables direct connection to legacy 5 V logic families |
| Propagation Delay | 11–29 ns at VCC = 4.5 V, CL = 50 pF - ensures timing compliance in sub-30 MHz synchronous control paths |
| Output Drive Strength | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple 74-series inputs or small capacitive loads |
| AEC-Q100 Grade | Grade 1 (−40 °C to +125 °C) - qualified for engine bay and transmission control unit environments |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets automotive robustness requirements for assembly and field operation |
Pinout & Package
74HCT02D-Q100 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, with gull-wing leads and pin 1 index marker.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | 1Y, 2Y, 3Y, 4Y | Independent NOR gate outputs - each drives one logic node with push-pull CMOS structure |
| 2, 5, 8, 11 | 1A, 2A, 3A, 4A | First input per gate - accepts TTL-level signals; includes internal clamp diode to VCC/GND |
| 3, 6, 9, 12 | 1B, 2B, 3B, 4B | Second input per gate - identical electrical behavior to A inputs |
| 7 | GND | Dedicated ground reference - must be connected to system 0 V plane for noise immunity and correct logic levels |
| 14 | VCC | Primary power supply - supplies all four gates; decoupling capacitor required within 10 mm |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including temperature cycling and HTRB |
| Input clamp diodes | Enable safe interface to voltages exceeding VCC when used with series current-limiting resistors |
| High noise immunity | Guaranteed 0.4 V noise margin at VCC = 4.5 V due to TTL-compatible input thresholds and CMOS design |
| Low static power consumption | ICC ≤ 40 μA at VCC = 5.5 V and full static loading - suitable for always-on vehicle modules |
| Side-wettable flanks not applicable | SO14 package lacks side-wettable flanks; AOI requires top-surface solder inspection only |
Applications
| Body Control Module Logic | Powertrain Sensor Interface |
|---|---|
Use Scenario: Combining door lock status and ignition signal to enable/disable window motor control logic. IC Role / Device Role / Timing Role: Combinatorial NOR gate implementing safety interlock function with deterministic <29 ns propagation.

Use Value: Prevents race conditions during boot by guaranteeing matched rise/fall times across four output channels. | Use Scenario: Enabling camera image sensor power only after stable MIPI clock and voltage rails are confirmed. IC Role / Device Role / Timing Role: Hardware-enforced power sequencing gate combining rail OK and clock stable signals. Use Value: Avoids sensor initialization failures caused by premature power enable, reducing field return rate. |
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 |
|---|---|---|---|
| 74HCT02PW-Q100 | TSSOP14 package (SOT402-1); 4.4 mm body width; 0.65 mm pitch; lower thermal resistance than SO14 | Better suited for high-density PCB layouts where board space is constrained | Select when footprint area reduction or improved thermal dissipation is prioritized over legacy SO14 compatibility |
| SN74HCT02QPWRQ1 | Texas Instruments part; same AEC-Q100 Grade 1 rating; identical logic function and DC specs; minor AC parameter variance (tpd = 13–30 ns) | Direct second-source option with TI's automotive support infrastructure and long-term availability program | Choose for multi-source procurement strategy or TI-design ecosystem alignment |
Compared with 74HCT02D-Q100, the TSSOP variant offers 25% smaller footprint and better thermal performance but requires requalification of solder paste profile, while the TI alternative provides identical functional behavior with different supply chain assurance and minor timing variation.

FAQ
What is the maximum allowable supply voltage for continuous operation?
The absolute maximum supply voltage is +7.0 V, but recommended continuous operation is limited to 4.5–5.5 V per AEC-Q100 Grade 1 specifications. Exceeding 5.5 V risks violating input/output voltage limits and may accelerate parametric drift over temperature and lifetime.
Can 74HCT02D-Q100 interface directly with 3.3 V microcontrollers?
No - its TTL input thresholds require VIH ≥ 2.0 V, which is compatible with 3.3 V logic high levels, but VCC must be 4.5–5.5 V to meet output drive specs. Direct connection without level shifting risks insufficient VOH and violates recommended operating conditions for VCC.
Is the SO14 package RoHS and REACH compliant?
Yes - 74HCT02D-Q100 conforms to EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with lead-free terminations and halogen-free molding compound, as documented in Nexperia's official compliance statements.
Does this device support hot insertion or live swapping?
No - it lacks hot-swap protection circuitry. Applying VCC before GND or removing either supply while powered may cause latch-up or damage due to uncontrolled current paths through internal clamp diodes and substrate parasitics.
