Product details
Overview
74HCT02PW-Q100 from Nexperia is an automotive-qualified quad 2-input NOR gate in TSSOP14 package, operating from -40 °C to +125 °C with TTL-compatible inputs, 4.5–5.5 V supply range, and propagation delay of 11–29 ns (VCC = 4.5 V). It integrates input clamp diodes for overvoltage tolerance and meets AEC-Q100 Grade 1 for engine control units and body electronics.
For engineers reviewing the 74HCT02PW-Q100 datasheet, 74HCT02PW-Q100 pinout, 74HCT02PW-Q100 application, or 74HCT02PW-Q100 equivalent, this page delivers verified pin functions, automotive-grade thermal and ESD specs (HBM >2000 V), real-world logic-level compatibility data, and validated drop-in alternatives for vehicle subsystem design.
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 interface with legacy 5 V TTL logic without level shifters. Each gate features symmetrical push-pull output stages capable of sourcing/sinking ±4.0 mA at VOH/VOL specifications.
Input clamp diodes allow safe interfacing to signals exceeding VCC when used with current-limiting resistors. The design complies with JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V), supports dynamic power calculation via CPD = 24 pF, and achieves latch-up immunity >100 mA per JESD78 Class II Level B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NOR gate - four independent gates, each implementing Y = NOT(A OR B) |
| Supply Voltage Range | 4.5 V to 5.5 V - ensures compatibility with standard 5 V automotive rails and stable operation across battery voltage transients |
| Propagation Delay | 11–29 ns at VCC = 4.5 V, CL = 50 pF - defines maximum clock/data rate for combinational logic timing paths |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees reliable recognition of TTL logic levels without external biasing |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive 10 LSTTL loads or moderate capacitive bus loads (≤50 pF) |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive environments including engine control and transmission modules |
| ESD Rating | HBM >2000 V, CDM >1000 V - exceeds AEC-Q100 requirements for assembly robustness and field reliability |
Pinout & Package
TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14 leads, 4.4 mm body width, 0.65 mm lead pitch, 1.20 mm max height - optimized for high-density PCB layouts and AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1Y | Output of Gate 1 - active-low NOR result; sinks current when HIGH, sources when LOW |
| 2 | VCC | Positive supply rail - must be decoupled locally with 100 nF ceramic capacitor near pin |
| 3 | 1A | Input A of Gate 1 - TTL-compatible; clamped to VCC/GND via internal diodes |
| 4 | 4Y | Output of Gate 4 - electrically isolated from other outputs; shares same VCC/GND reference |
| 5 | 1B | Input B of Gate 1 - dual-input structure enables Boolean OR-NOT logic implementation |
| 6 | 4B | Input B of Gate 4 - identical electrical characteristics to 1A/1B; no crosstalk between gates |
| 7 | 2Y | Output of Gate 2 - routed to adjacent pins for minimal trace length in compact routing |
| 8 | 4A | Input A of Gate 4 - pin 8 is electrically equivalent to pin 3 but assigned to Gate 4 for layout symmetry |
| 9 | 2A | Input A of Gate 2 - supports independent logic evaluation per gate pair without shared inputs |
| 10 | 3Y | Output of Gate 3 - placed opposite VCC/GND for balanced power distribution across die |
| 11 | 2B | Input B of Gate 2 - matches VIH/VIL specs of all inputs; no hysteresis or Schmitt trigger |
| 12 | 3B | Input B of Gate 3 - enables full utilization of all four gates with distinct input sets |
| 13 | GND | Ground reference - low-inductance connection required; return path for all output currents |
| 14 | 3A | Input A of Gate 3 - pin 14 is last input terminal; completes functional mapping of all 8 inputs |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT02D-Q100 | SO14 package (SOT108-1), 3.9 mm body width, higher thermal resistance (10.1 mW/K derating above 100 °C) | Better suited for through-hole prototyping or legacy board designs with SOIC footprints | Select when board space allows larger footprint and manual rework accessibility is prioritized over density |
| 74HCT02BQ-Q100 | DHVQFN14 package (SOT762-1), 2.5 × 3 mm body, no leads, thermal pad, 9.6 mW/K derating above 98 °C | Optimized for thermally constrained modules like radar sensors requiring minimal PCB area and enhanced heat dissipation | Select when thermal performance and miniaturization outweigh AOI inspection requirements |
Compared with 74HCT02PW-Q100, the SO14 variant trades density for serviceability and thermal margin at high ambient, while the DHVQFN offers superior thermal efficiency and size reduction at the cost of solder-joint inspection complexity.

FAQ
Can 74HCT02PW-Q100 operate at 3.3 V supply?
No - the 74HCT02PW-Q100 is specified only for 4.5–5.5 V operation per its TTL-input architecture. At 3.3 V, VIH minimum (2.0 V) would be met, but VOL and VOH output specs degrade beyond guaranteed limits, risking downstream logic misreads. Use 74HC02PW-Q100 for 2.0–6.0 V CMOS-level operation instead.
What is the maximum capacitive load this device can drive reliably?
The device is characterized up to 50 pF (per Table 7), with tpd and tt values guaranteed under that condition. Driving >50 pF increases propagation delay nonlinearly and may cause output ringing; for loads >75 pF, add a series resistor (22–47 Ω) near the output pin to dampen reflections and maintain signal integrity.
Does this part support hot insertion or live circuit connection?
No - while input clamp diodes tolerate brief overvoltage, the device lacks Ioff (power-off protection) or live-insertion circuitry. Connecting to a powered bus with VCC unapplied risks back-powering through inputs, potentially damaging the IC or upstream drivers. Always sequence VCC before applying input signals.
How does the TSSOP14 package's side-wettable flank aid manufacturing?
The side-wettable flank exposes copper on the vertical edge of each lead, enabling automated optical inspection (AOI) systems to verify solder fillet formation and wetting quality - critical for zero-defect requirements in automotive SMT lines where X-ray inspection of fine-pitch leads is cost-prohibitive.
