Product details
Overview
74HC4002D,653 from Nexperia is a dual 4-input CMOS NOR gate in SO14 package, operating from 2.0 V to 6.0 V supply, with propagation delay as low as 9 ns at VCC = 5.0 V and CL = 15 pF, ±25 mA output drive capability, and guaranteed operation from -40 °C to +125 °C - used for logic-level signal combining and active-low enable control in industrial control panels.
For engineers reviewing the 74HC4002D,653 datasheet, 74HC4002D,653 pinout, 74HC4002D,653 application, or 74HC4002D,653 equivalent, key selection criteria include input voltage thresholds (VIH = 3.15 V min at VCC = 4.5 V), output drive strength under load, thermal derating behavior above 100 °C, and compatibility with 3.3 V/5 V mixed-signal systems.
Technical Context
The 74HC4002D implements two independent 4-input NOR functions using standard CMOS silicon technology, with input clamp diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used. Each gate exhibits symmetrical HIGH/LOW output voltage levels across its full operating temperature range.
Its logic behavior follows strict Boolean NOR truth table: output is HIGH only when all four inputs are LOW; any HIGH input forces output LOW. Propagation delays are characterized separately for rising (tPLH) and falling (tPHL) edges, with typical values tightly specified at 25 °C and over extended temperature ranges (-40 °C to +125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 6.0 V - supports direct interface with both 3.3 V and 5 V logic families without level translation. |
| Propagation Delay | 9 ns (typ) at VCC = 5.0 V, CL = 15 pF - enables reliable timing in sub-100 MHz synchronous logic blocks. |
| Output Drive | ±25 mA - sufficient to directly drive multiple 74HC inputs or small LEDs with series resistor. |
| Input Thresholds | VIH = 3.15 V min, VIL = 1.35 V max at VCC = 4.5 V - ensures noise margins >0.8 V in 5 V systems. |
| Operating Temp | -40 °C to +125 °C - qualified for under-hood industrial and power-conversion control environments. |
| Power Dissipation | 500 mW max (SO14); derates 10.1 mW/K above 100 °C - defines thermal design margin for PCB layout. |
Pinout & Package
74HC4002D,653 uses SOT108-1 (SO14) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 13 | 1Y, 2Y | Outputs of Gate 1 and Gate 2 - open-drain capable only when externally pulled up; CMOS push-pull structure. |
| 2–5 | 1A–1D | Inputs to Gate 1 - accept standard CMOS logic levels; include internal clamp diodes to VCC/GND. |
| 6, 8 | n.c. | No-connect pins - must remain unconnected per datasheet; no internal connection or test function. |
| 7 | GND | Ground reference for all inputs/outputs - requires low-impedance PCB plane connection for noise immunity. |
| 9–12 | 2A–2D | Inputs to Gate 2 - electrically identical to 1A–1D; fully independent from Gate 1 inputs. |
| 14 | VCC | Positive supply rail - decoupling capacitor (100 nF ceramic) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 2.0 V to 6.0 V operation enables drop-in replacement across legacy 5 V and modern 3.3 V systems. |
| High Noise Immunity | Input hysteresis not present, but VIH/VIL separation >1.8 V at VCC = 6.0 V provides robust EMI tolerance. |
| Latch-up Immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events. |
| ESD Protection | HBM >2000 V, CDM >1000 V - reduces need for external protection in board-level ESD zones. |
| Temperature Range | Specified from -40 °C to +125 °C - eliminates derating calculations for most industrial ambient conditions. |
Applications
| Industrial PLC I/O Expansion | Automated Test Equipment (ATE) Signal Gating |
|---|---|
|

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 |
|---|---|---|---|
| SN74HC4002DR | TI part in SO14; identical logic function but VIH/VIL thresholds differ slightly (VIH = 3.15 V min at VCC = 4.5 V same; VOL = 0.33 V max vs Nexperia's 0.26 V max). | Higher VOL may reduce noise margin in high-fanout 5 V systems; otherwise pin- and function-compatible. | Select if TI supply chain preference exists or if existing designs use TI qualification data. |
| 74VHC4002M | ON Semiconductor part; higher speed (tpd = 7.5 ns typ at VCC = 5 V), lower ICC (1 μA max), but narrower temp range (-40 °C to +85 °C only). | Not suitable for automotive under-hood or industrial high-temp deployments requiring +125 °C operation. | Choose for speed-critical consumer or telecom applications where extended temperature is unnecessary. |
Compared with SN74HC4002DR and 74VHC4002M, the 74HC4002D,653 offers superior thermal robustness (+125 °C), tighter VOL specification, and broader industry qualification - making it optimal for industrial control and power electronics where reliability outweighs marginal speed gains.

FAQ
Can 74HC4002D,653 operate reliably at 2.0 V supply?
Yes - the device is fully specified down to 2.0 V supply voltage, with VIH = 1.5 V min and VOL = 0.1 V max at that rail. Propagation delay increases to 100 ns (max) at 2.0 V, making it suitable for ultra-low-power battery-backed logic where speed is secondary to energy efficiency.
Are pins 6 and 8 truly unconnected internally?
Yes - pins 6 and 8 are confirmed no-connect (n.c.) terminals with no internal silicon connection. They must remain unconnected on PCB; routing traces or vias to them violates Nexperia's recommended layout and may cause mechanical stress or unintended coupling.
Does 74HC4002D,653 support mixed-voltage interfacing?
Yes - input clamp diodes allow safe connection of inputs to voltages up to VCC + 0.5 V when series current-limiting resistors are used. This enables direct interfacing with 5 V signals while operating at 3.3 V VCC, provided input current stays below ±20 mA.
How does thermal derating affect maximum power dissipation?
For the SO14 package (SOT108-1), total power dissipation derates linearly at 10.1 mW/K above 100 °C. At 125 °C ambient, Ptot drops to 500 mW − (25 K × 10.1 mW/K) = 247 mW - requiring careful thermal pad design or airflow in enclosed enclosures.
