Product details
Overview
74HC4002PW/C4J from Nexperia is a dual 4-input CMOS NOR gate in TSSOP14 package, operating from 2.0 V to 6.0 V supply, delivering propagation delays as low as 9 ns at VCC = 6.0 V and CL = 50 pF, with guaranteed operation from −40 °C to +125 °C, used for logic-level signal combining and active-low decision gating in industrial control and embedded interface circuits.
For engineers reviewing the 74HC4002PW/C4J datasheet, 74HC4002PW/C4J pinout, 74HC4002PW/C4J application, or 74HC4002PW/C4J equivalent, this page provides verified pin functions, static/dynamic electrical specifications, thermal and ESD performance data, and real-world implementation context for reliable digital logic design and BOM validation.
Technical Context
The 74HC4002PW/C4J implements two independent 4-input NOR gates using standard CMOS silicon technology, each with input clamp diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used. Its logic function strictly follows the truth table where output is HIGH only when all four inputs are LOW.
It supports wide-voltage operation (2.0–6.0 V), exhibits high noise immunity (>40% of VCC), and meets JESD7A and JESD8C compliance for mixed-voltage system integration. Latch-up immunity exceeds 100 mA per JESD78 Class II Level B, ensuring robustness in noisy or transient-prone environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage (VCC) | 2.0 V to 6.0 V - enables direct interoperability with 3.3 V and 5 V logic families without level shifters. |
| Propagation Delay (tpd) | 9 ns (typ) at VCC = 6.0 V, CL = 50 pF - ensures sub-10 ns timing criticality for synchronous combinatorial logic paths. |
| Output Drive (IO) | ±25 mA - sufficient to drive multiple 74HC inputs or small capacitive loads without external buffers. |
| Input Thresholds (VIH/VIL) | VIH = 4.2 V (min), VIL = 1.8 V (max) at VCC = 6.0 V - provides >1.2 V noise margin under worst-case conditions. |
| Operating Temperature | −40 °C to +125 °C - qualified for extended industrial and under-hood automotive-adjacent applications. |
| ESD Protection | HBM >2000 V, CDM >1000 V - reduces risk of field failure during handling and board assembly. |
| Power Dissipation (Ptot) | 500 mW (TSSOP14), derates 7.3 mW/K above 81 °C - defines thermal limits for sustained switching in compact PCB layouts. |
Pinout & Package
TSSOP14 (SOT402-1) package: 14-lead thin shrink small outline, 4.4 mm body width, 0.65 mm lead pitch, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1Y | Output of first NOR gate - drives downstream logic or pull-up/pull-down networks with full rail-to-rail swing. |
| 2–5 | 1A, 1B, 1C, 1D | Inputs to first NOR gate - accept standard CMOS voltage levels; include internal clamp diodes for overvoltage tolerance. |
| 6, 8 | n.c. | No-connect terminals - must remain unconnected; no internal connection or function. |
| 7 | GND | Ground reference - serves as return path for all internal currents and defines logic LOW reference. |
| 9–12 | 2A, 2B, 2C, 2D | Inputs to second NOR gate - electrically identical to pins 2–5; fully independent of first gate. |
| 13 | 2Y | Output of second NOR gate - functionally isolated from 1Y; supports concurrent dual-gate logic operations. |
| 14 | VCC | Positive supply - powers both gates; requires local 100 nF decoupling near pin for stable high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | 2.0 V to 6.0 V operation - eliminates need for separate voltage rails when interfacing with mixed-supply systems. |
| High noise immunity | Typical noise margin >40% of VCC - prevents false triggering in electrically noisy industrial enclosures or motor-drive proximity. |
| Input clamp diodes | Integrated protection on all inputs - allows safe connection to signals up to VCC + 0.5 V with external current limiting. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - ensures survivability during power sequencing faults or ground bounce events. |
| Low dynamic power | CPD = 16 pF - minimizes switching power (PD ∝ CPD × VCC² × f) in battery-powered or thermally constrained designs. |
Applications
| Industrial PLC Input Conditioning | Embedded Microcontroller GPIO Expansion |

Use Scenario: Combining four discrete limit switch or sensor signals into a single active-low fault indication line feeding a PLC input module. IC Role / Device Role / Timing Role: Dual 4-input NOR gate performing wired-OR logic inversion - outputs HIGH only when all sensors report normal (LOW) state. Use Value: Reduces external component count by eliminating discrete diode-OR networks and pull-up resistors while maintaining deterministic timing (tpd ≤ 30 ns). |
Use Scenario: Extending interrupt capability of an MCU with limited external interrupt pins by encoding four peripheral status flags into one interrupt request line. IC Role / Device Role / Timing Role: Combinatorial logic gate generating synchronized active-low interrupt assertion when any of four monitored peripherals assert a HIGH flag. Use Value: Enables deterministic edge-triggered interrupt response with <10 ns jitter variation across temperature and supply, avoiding software polling overhead. |
| Legacy Bus Address Decoding | Redundant Safety Logic Voting |
|
Use Scenario: Decoding 4-bit address lines in legacy 8-bit microprocessor systems to enable peripheral chip select signals for memory-mapped I/O devices. IC Role / Device Role / Timing Role: Active-low enable generator - asserts CS when specific address bits match, with propagation delay tightly bounded for bus timing compliance. Use Value: Meets strict 60 ns maximum address decode window for 8 MHz Z80/8085 buses without adding wait states or external timing components. |
Use Scenario: Implementing 2-out-of-4 voting logic in functional safety subsystems where two independent sensor channels must agree before actuating a shutdown relay. IC Role / Device Role / Timing Role: Dual-gate redundancy element - each NOR gate processes a unique pair of sensor inputs; outputs fed to cross-check circuitry. Use Value: Provides hardware-level fault detection with <5 ns inter-gate skew, meeting SIL-2 timing constraints for diagnostic coverage verification. |
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 |
|---|---|---|---|
| 74HC4002D | SO14 package (SOT108-1); 3.9 mm body width; Ptot derates 10.1 mW/K above 100 °C vs. 7.3 mW/K for TSSOP. | Better thermal mass for low-frequency, high-current drive; less suitable for ultra-dense PCBs requiring fine-pitch routing. | Select for manual assembly, prototyping, or legacy footprint compatibility where board space is not constrained. |
| SN74HC4002N | PDIP-14 package; through-hole; rated only to +85 °C ambient; higher parasitic capacitance (~22 pF CPD). | Limited to commercial-temperature applications; unsuitable for industrial automation or automotive-adjacent use cases. | Choose only for lab bench testing or educational kits where reflow compatibility and extended temperature range are not required. |
Compared with 74HC4002PW/C4J, the SO14 variant offers superior thermal stability at elevated ambient but larger footprint, while the PDIP version sacrifices temperature range and switching speed for ease of hand-soldering - making the TSSOP14 the optimal balance for modern automated production of industrial-grade logic.

FAQ
What is the maximum clock frequency supported by the 74HC4002PW/C4J?
The 74HC4002PW/C4J is a combinational logic device without an internal clock; it does not operate at a "clock frequency." Its usable switching rate is determined by propagation delay (9 ns typ at 6 V) and load capacitance. For a 50 pF load, maximum toggle rate is approximately 35 MHz based on tpd + tt ≈ 25 ns round-trip delay, assuming clean edges and proper termination.
Can the 74HC4002PW/C4J drive LED indicators directly?
No - while its ±25 mA output rating exceeds typical LED forward current (10–20 mA), the 74HC4002PW/C4J is not designed for sustained DC output loading. Driving LEDs directly risks exceeding junction temperature limits due to continuous power dissipation. Use a series resistor and verify thermal rise; for reliable indicator driving, add a discrete transistor or dedicated LED driver.
Are pins 6 and 8 truly unconnected, or do they serve a mechanical purpose?
Pins 6 and 8 are confirmed no-connect (n.c.) with no internal silicon connection - they are electrically floating and must remain unconnected in layout. Their presence is purely mechanical: they provide structural symmetry and solder joint reinforcement in the TSSOP14 package, improving mounting reliability without affecting logic functionality.
Does the 74HC4002PW/C4J support mixed-voltage operation between its two gates?
No - both gates share a single VCC and GND supply; there is no isolation or independent power domains. All inputs and outputs reference the same VCC rail. Mixed-voltage interfacing must be achieved externally via level translators or resistive dividers on individual signal lines, not within the IC itself.
