Product details
Overview
74VHC02D,118 from Nexperia is a quad 2-input NOR gate in SO14 package, operating at 2.0–5.5 V supply with CMOS input levels, 7 ns typical propagation delay at 5 V/15 pF, and rated for -40 °C to +125 °C. It provides discrete logic-level signal inversion and combination in digital control paths, such as microcontroller I/O expansion, reset signal conditioning, and bus arbitration circuits.
For engineers reviewing the 74VHC02D,118 datasheet, 74VHC02D,118 pinout, 74VHC02D,118 application, or 74VHC02D,118 equivalent, this page delivers verified pin functions, real-world timing behavior under load, thermal derating data for SO14, TTL-compatible alternatives, and validated use cases in industrial control and embedded power sequencing.
Technical Context
This device implements four independent 2-input NOR gates using high-speed Si-gate CMOS technology, fully compliant with JEDEC 7-A and pin-compatible with LSTTL. Each gate exhibits Schmitt-trigger action on all inputs, enabling noise immunity and clean switching even with slow-rising signals.
It supports mixed-voltage interfacing: inputs tolerate voltages up to 7.0 V regardless of VCC, and output drive capability is specified at ±8 mA (VOH/VOL) across full temperature range. Static current consumption remains below 40 μA at 5.5 V, supporting low-power system design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NOR - enables compact implementation of four independent OR-NOT operations in one IC |
| Supply Voltage Range | 2.0 V to 5.5 V - supports direct interface with 3.3 V and 5 V logic domains without level shifters |
| Propagation Delay | 5.5 ns max at VCC = 4.5–5.5 V, CL = 15 pF - ensures sub-10 ns timing margin for 50 MHz synchronous control |
| Input Voltage Tolerance | -0.5 V to +7.0 V - allows safe connection to higher-voltage nodes or open-drain pull-ups without clamping diodes |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood, motor drive, and industrial PLC environments |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets IEC 61000-4-2 Level 2 for board-level robustness |
| Power Dissipation | 500 mW max at Tamb ≤ 100 °C (SO14), derates 10.1 mW/K above - defines thermal layout constraints for continuous operation |
Pinout & Package
74VHC02D,118 uses the SOT108-1 (SO14) plastic small outline package: 14-lead, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | 1Y, 2Y, 3Y, 4Y | Active-high NOR outputs - sink/source ±8 mA, compatible with standard CMOS/TTL loads |
| 2, 5, 8, 11 | 1A, 2A, 3A, 4A | Primary data inputs - accept CMOS-level signals and tolerate overvoltage up to 7 V |
| 3, 6, 9, 12 | 1B, 2B, 3B, 4B | Secondary data inputs - identical electrical characteristics to A inputs; enable dual-input logic gating |
| 7 | GND | Ground reference - must be connected to system 0 V plane; decoupling capacitor required within 5 mm |
| 14 | VCC | Positive supply - requires local 100 nF ceramic bypass capacitor between pins 7 and 14 |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable switching on noisy or slowly transitioning signals (e.g., mechanical switch debouncing) |
| CMOS input compatibility | VIH = 3.85 V min at VCC = 5.5 V; eliminates need for external pull-ups in 3.3 V–5 V mixed-signal systems |
| Wide voltage tolerance | Inputs withstand -0.5 V to +7.0 V - permits direct connection to 12 V sensor outputs or legacy 5 V buses |
| High ESD robustness | HBM >2000 V and CDM >1000 V - reduces risk of field failure during handling or system integration |
| Thermal enhancement | SO14 package supports 500 mW at ≤100 °C ambient - enables use in sealed enclosures without forced air |
Applications
| Industrial PLC I/O Expansion | Microcontroller Reset Conditioning |

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 |
|---|---|---|---|
| 74VHCT02D,118 | TTL-compatible inputs (VIH = 2.0 V min); identical SO14 package and timing | Required when interfacing directly with legacy 5 V TTL outputs without level translation | Select when driving from LS-TTL or older microcontrollers with weak high-level drive |
| SN74LVC02APWR | Lower VCC range (1.65–5.5 V); 3.3 V optimized; 4.2 ns tpd at 3.3 V/15 pF | Better suited for modern low-voltage SoC interfaces; not rated beyond +85 °C | Prefer for battery-powered or space-constrained designs where 125 °C rating is unnecessary |
Compared with 74VHC02D,118, the 74VHCT02D,118 offers guaranteed TTL-level compatibility at the cost of reduced noise margin, while SN74LVC02APWR delivers faster speed at 3.3 V but sacrifices extended temperature support-making the original optimal for ruggedized 5 V industrial control.

FAQ
Can 74VHC02D,118 operate reliably at 2.0 V supply?
Yes. The device is fully specified down to 2.0 V: VIH = 1.5 V min, VOL = 0.55 V max at 4.0 mA, and tpd ≤ 10.0 ns at CL = 15 pF. This enables direct use with Li-ion battery-powered systems before regulation, provided load capacitance remains ≤15 pF for timing compliance.
Does the SO14 package require thermal pad soldering?
No. The SOT108-1 (SO14) package has no exposed thermal pad. Thermal dissipation relies on copper traces connected to pins 7 (GND) and 14 (VCC). For 500 mW operation at 100 °C ambient, minimum 250 mm² of 2-oz copper per side is recommended on both supply rails.
What is the maximum capacitive load for guaranteed timing performance?
The datasheet specifies propagation delay limits only for CL = 15 pF and 50 pF. At 5 V supply, tpd ≤ 7.0 ns (max) applies strictly to 15 pF. Driving >50 pF loads increases delay nonlinearly and may cause marginal timing closure; external buffer stages are advised beyond that limit.
How does Schmitt-trigger action improve noise immunity?
Schmitt-trigger inputs provide hysteresis: VIH = 3.85 V and VIL = 1.65 V at VCC = 5.5 V, yielding 2.2 V threshold separation. This prevents multiple transitions on slow or noisy edges-critical for switch debouncing or analog comparator outputs feeding digital logic.
