Product details

Overview

74LVC02ADB,112 from Nexperia is a quad 2-input NOR gate logic IC operating at 1.65–3.6 V supply, with typical propagation delay of 3.1 ns at 3.3 V, ±24 mA output drive, and TTL-compatible inputs. It performs basic Boolean NOR logic in digital control signal routing for industrial I/O modules.

For engineers reviewing the 74LVC02ADB,112 datasheet, 74LVC02ADB,112 pinout, 74LVC02ADB,112 application, or 74LVC02ADB,112 equivalent, key selection factors include voltage range compatibility, output current capability, propagation delay budget, and SO-14 package footprint constraints.

Technical Context

This device implements four independent 2-input NOR gates using silicon-gate CMOS technology. Each gate features buffered outputs, symmetric rise/fall times (typ. 2.8 ns), and input hysteresis (ΔV_hys = 0.3 V) for noise immunity on slow-rising signals.

It operates across the full 1.65–3.6 V V_CC range with guaranteed AC/DC performance per JEDEC JESD8-12A. Input thresholds scale with V_CC, enabling mixed-voltage interface between 1.8 V and 3.3 V domains without level shifters.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CC Range	1.65 V to 3.6 V - supports direct interfacing with 1.8 V and 3.3 V logic families
t_PD (max)	5.2 ns at V_CC = 3.3 V - enables use in sub-100 MHz synchronous control paths
I_OH/I_OL	±24 mA at V_CC = 3.3 V - drives multiple 74LVC inputs or small LED loads directly
Input Hysteresis	0.3 V - suppresses chatter on noisy or slowly transitioning control lines
ESD Rating	HBM ±2 kV - meets IEC 61000-4-2 Level 2 for board-level robustness
Quiescent Current	10 µA max at 25 °C - suitable for low-power state-holding logic

Pinout & Package

Supplied in a 14-pin small outline package (SO-14), body width 3.9 mm, pitch 1.27 mm, lead finish matte tin.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 5, 6, 8, 9, 12, 13	Input A/B of NOR gates	Dual-rail compatible inputs with Schmitt-trigger hysteresis option (not enabled by default)
3, 4, 10, 11	Output Y of NOR gates	Push-pull CMOS outputs capable of sourcing/sinking 24 mA
7	GND	Ground reference for all logic and I/O
14	V_CC	Positive supply rail - must be decoupled locally with 100 nF ceramic capacitor

Key Features

Feature	Design Value
Wide supply voltage range	1.65–3.6 V operation enables single-supply designs across 1.8 V and 3.3 V systems
High noise immunity	0.3 V input hysteresis reduces susceptibility to EMI-induced false triggering
Low dynamic power	Typical I_CC = 1 µA at 1 MHz toggle rate - extends battery life in portable logic
IOFF protection	Prevents current backflow when V_CC = 0 V - safe for hot-insertion and partial power-down

Applications

Industrial PLC I/O Expansion

Automotive Body Control Module

Use Scenario: Adding discrete logic for status flag combination and fault masking in modular I/O racks.

IC Role / Device Role / Timing Role: NOR gate implements active-low enable logic with fast response to sensor interrupt signals.

Use Scenario: Combining door lock/unlock request signals with safety interlock conditions before actuator activation.

IC Role / Device Role / Timing Role: Performs real-time hardware-level arbitration of conflicting control commands.

Use Value: ±24 mA drive strength directly interfaces with automotive-grade optocouplers and relay drivers.

Medical Infusion Pump UI Logic

POS Terminal Button Debounce

Use Scenario: Validating simultaneous keypress combinations (e.g., "Start + Confirm") while rejecting spurious contact bounce.

IC Role / Device Role / Timing Role: NOR-based combinational logic enforces multi-key security policy in hardware.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NOR gate logic applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC02APW	TSSOP-14 package, identical electrical specs, same 1.65–3.6 V range and 5.2 ns t_PD	Requires different PCB land pattern; slightly higher thermal resistance (θ_JA = 120 °C/W vs. 105 °C/W)	Preferred where board space is constrained and thermal margin allows
74AHC02PW,118	Higher V_CC range (2–5.5 V), faster t_PD (3.7 ns @ 5 V), but no IOFF protection	Not suitable for partial-power-down systems; requires level shifting below 2 V	Select only when 5 V operation is mandatory and hot-swap is not required

Compared with SN74LVC02APW and 74AHC02PW,118, the 74LVC02ADB,112 offers optimal balance of low-voltage compatibility, IOFF safety, and SO-14 manufacturability - making it preferred for cost-sensitive, mixed-voltage industrial control boards.

FAQ

Is 74LVC02ADB,112 compatible with 5 V TTL inputs?

No - its absolute maximum input voltage is V_CC + 0.5 V. Driving it with 5 V signals risks latch-up or permanent damage unless external clamping or level-shifting is used. It is designed for 1.8 V and 3.3 V systems only.

Does this device support partial power-down operation?

Yes - it features IOFF circuitry that disables I/Os when V_CC = 0 V, preventing current backflow and enabling safe hot-plug operation in modular backplane systems.

What is the recommended decoupling for 74LVC02ADB,112?

A 100 nF X7R ceramic capacitor placed within 3 mm of pins 7 (GND) and 14 (V_CC) is required. For boards with multiple LVC devices, add one 4.7 µF tantalum per 5–10 ICs on the same V_CC rail.

Can this NOR gate be used as an oscillator?

No - it lacks internal feedback path or phase-shift network. While unstable ring oscillation may occur with external RC, it is not characterized or guaranteed for such use; dedicated oscillator ICs or crystal-based solutions are recommended instead.
