Product details

Overview

74HC02D,653 from Nexperia is a quad 2-input NOR gate in SO14 (SOT108-1) package, operating from 2.0 V to 6.0 V supply, delivering CMOS-level input compatibility, propagation delay as low as 7 ns at VCC = 6.0 V, and guaranteed operation from –40 °C to +125 °C - used for digital logic inversion, enable/disable control, and reset signal conditioning in industrial microcontroller interfaces.

For engineers reviewing the 74HC02D,653 datasheet, 74HC02D,653 pinout, 74HC02D,653 application, or 74HC02D,653 equivalent, key selection considerations include supply voltage range (2.0–6.0 V), output drive strength (±25 mA), input clamp diode support for overvoltage-tolerant interfacing, and thermal performance in SO14 package up to +125 °C ambient.

Technical Context

The 74HC02D implements four independent 2-input NOR gates using silicon-gate CMOS technology, with input clamp diodes enabling safe interface to signals exceeding VCC when used with current-limiting resistors. Each gate exhibits symmetrical HIGH/LOW output voltage thresholds referenced to VCC.

Its logic function follows strict Boolean NOR behavior: output is HIGH only when both inputs are LOW; all other input combinations yield LOW. Propagation delay is specified across full temperature and voltage ranges, with dynamic power dissipation modeled via CPD = 22 pF and load-dependent calculation.

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	2.0 V to 6.0 V - supports mixed-voltage system interfacing (e.g., 3.3 V MCU with 5 V peripherals)
Propagation Delay (tpd)	7 ns (typ) at VCC = 6.0 V, CL = 50 pF - enables reliable timing in sub-100 MHz synchronous logic paths
Output Drive Current	±25 mA - sufficient to directly drive LED indicators, small MOSFET gates, or TTL-compatible inputs
Operating Temperature	–40 °C to +125 °C - qualified for under-hood industrial and extended-temperature embedded control
Input Clamp Diodes	Integrated - allows safe connection of inputs to voltages > VCC when series current-limiting resistors are used
Power Dissipation (Ptot)	500 mW (SO14, ≤100 °C); derates linearly at 10.1 mW/K above 100 °C - defines thermal design margin in PCB layout

Pinout & Package

74HC02D,653 uses the SO14 (SOT108-1) 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	Independent NOR gate outputs - each sinks or sources up to ±25 mA, rail-to-rail swing
2, 5, 8, 11	1A, 2A, 3A, 4A	First input per gate - CMOS-level compatible, with clamp diodes to VCC and GND
3, 6, 9, 12	1B, 2B, 3B, 4B	Second input per gate - identical electrical characteristics to A inputs
7	GND	Ground reference (0 V) - must be low-impedance return path for all four gates' output currents
14	VCC	Positive supply - powers all gates; decoupling capacitor (100 nF) required within 10 mm

Key Features

Feature	Design Value
Wide supply range	2.0 V to 6.0 V - eliminates need for level shifters in multi-rail systems (e.g., 3.3 V logic controlling 5 V analog circuitry)
High noise immunity	Typical VIH/VIL margins ≥70% of VCC - rejects EMI-induced glitches on control lines in motor drives or power supplies
Latch-up robustness	>100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overcurrent events
ESD protection	HBM >2000 V, CDM >1000 V - withstands handling and board assembly without external protection components
Thermal qualification	Rated to +125 °C ambient - supports use in sealed enclosures or near heat-generating components without derating

Applications

Industrial PLC I/O Conditioning

Microcontroller Reset Logic

Use Scenario: Isolating and combining multiple sensor fault signals into a single hardware reset line for a programmable logic controller CPU module.

IC Role / Device Role / Timing Role: NOR gate acts as active-LOW wired-OR combiner - any fault input (LOW) forces reset output LOW.

Use Value: Eliminates need for discrete diodes and pull-up resistors; ensures deterministic reset assertion with <7 ns delay variation across temperature.

Use Scenario: Generating a synchronized power-on reset pulse that holds the MCU in reset until both VCC stabilizes and an external watchdog timeout expires.

IC Role / Device Role / Timing Role: One gate combines delayed power-good signal and inverted watchdog timeout - output goes HIGH only when both conditions met.

Use Value: Provides glitch-free, monotonic reset release without RC timing drift; leverages built-in input clamps for direct connection to unregulated auxiliary rails.

Motor Driver Enable Control

LED Status Indicator Logic

Use Scenario: Enabling/disabling dual H-bridge drivers based on thermal shutdown status and direction command validity.

IC Role / Device Role / Timing Role: Two gates implement NAND-equivalent logic (via NOR + inversion) to disable driver outputs if either overtemperature or invalid command is detected.

Use Value: Achieves fail-safe motor control with <10 ns worst-case response time; operates reliably at 24 V bus-derived 5 V supply.

Use Scenario: Driving bi-color LED indicators showing system state (e.g., RUN/ERROR) using complementary outputs from two NOR gates.

IC Role / Device Role / Timing Role: Gates configured as inverters drive common-anode LED pair - one output sources current, the other sinks.

Use Value: Delivers 20 mA per LED segment directly from outputs; eliminates external transistors while maintaining consistent brightness across supply range (2.0–6.0 V).

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,653	TTL-compatible inputs (VIH = 2.0 V min), otherwise identical SO14 pinout and DC specs	Better suited for interfacing with legacy 5 V TTL outputs without level translation	Select when driving from standard 5 V TTL sources; avoid if interfacing with modern 3.3 V CMOS where HC's higher VIH improves noise margin
SN74LV02ADR	TI part, 2.0–5.5 V supply, lower ICC (1 μA typ), same SO14 footprint but different AC specs (tpd = 7.5 ns @ 3.3 V)	Slightly slower at 3.3 V, but superior quiescent current for battery-powered sleep modes	Prefer for ultra-low-power portable designs; verify timing closure with LV family's reduced drive strength (±12 mA)

Compared with 74HC02D,653, the 74HCT02D,653 offers TTL input thresholds for legacy compatibility but sacrifices noise margin in mixed-voltage systems, while SN74LV02ADR trades minor speed reduction for significantly lower static current - making it optimal for energy-constrained applications where 74HC02D's 25 mA drive is unnecessary.

FAQ

Can 74HC02D,653 operate at 3.3 V supply?

Yes - the 74HC02D,653 is fully specified from 2.0 V to 6.0 V, including 3.3 V operation. At VCC = 3.3 V, typical propagation delay is ~12 ns (CL = 50 pF), VIH = 2.1 V min, and VOL = 0.26 V max at 4 mA sink, meeting standard 3.3 V LVTTL and LVCMOS interface requirements without level shifting.

Does 74HC02D,653 require external pull-up or pull-down resistors on unused inputs?

Yes - unused inputs must be terminated to VCC or GND. Floating CMOS inputs cause increased ICC, unpredictable logic states, and potential oscillation due to noise coupling. A 10 kΩ pull-up to VCC is recommended for unused A/B inputs to ensure defined HIGH state and minimize power consumption.

What is the maximum capacitive load the 74HC02D,653 can drive reliably?

The device is characterized up to 50 pF (per output), with guaranteed tpd and transition times. Driving >50 pF increases propagation delay nonlinearly and may cause ringing or undershoot; for loads >100 pF, add a series resistor (22–47 Ω) near the output to dampen reflections and maintain signal integrity in PCB traces longer than 5 cm.

Is the SO14 package of 74HC02D,653 RoHS-compliant and halogen-free?

Yes - the 74HC02D,653 in SOT108-1 package meets RoHS Directive 2011/65/EU and is certified halogen-free per IEC 61249-2-21, with brominated flame retardants and chlorine content below 900 ppm each, verified in Nexperia's material declarations (Doc ID: MTL-74HC02D).
