Product details

Overview

74HC03D,652 from Nexperia is a quad 2-input NAND gate IC with open-drain outputs, designed for wired-AND logic, level translation, and bus interface applications in industrial control and digital signal conditioning circuits. It operates from 2.0 V to 6.0 V, delivers propagation delay as low as 8 ns at VCC = 6.0 V, supports -40 °C to +125 °C ambient range, and features CMOS-level input compatibility.

For engineers reviewing the 74HC03D,652 datasheet, 74HC03D,652 pinout, 74HC03D,652 application, or 74HC03D,652 equivalent, this page provides verified functional role, SO14 package mapping, open-drain output behavior, temperature-rated static/dynamic specs, and real-world substitution guidance - all derived from Nexperia's Rev. 7 product data sheet.

Technical Context

This device implements four independent NAND gates, each with open-drain output architecture enabling flexible pull-up configuration and voltage-level interoperability across mixed-supply systems. Input clamp diodes allow safe interfacing to signals exceeding VCC when used with current-limiting resistors.

It adheres to JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards, offers HBM ESD protection >2000 V and CDM >1000 V, and maintains guaranteed operation over full industrial and extended automotive-grade temperature ranges (-40 °C to +125 °C).

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Quad 2-input NAND with open-drain outputs - enables wired-AND, I²C bus pull-up, and multi-source signal arbitration.
Supply Voltage Range	2.0 V to 6.0 V - supports direct integration into 3.3 V and 5 V systems without level shifters.
Propagation Delay	8 ns typical at VCC = 6.0 V, CL = 50 pF - ensures timing-critical combinational logic performance in high-speed digital interfaces.
Input Compatibility	CMOS-level inputs (VIH ≥ 3.15 V @ VCC = 4.5 V) - compatible with standard HC-family logic and microcontroller GPIOs.
Operating Temperature	-40 °C to +125 °C - qualified for under-hood, motor control, and industrial PLC environments.
ESD Protection	HBM >2000 V, CDM >1000 V - reduces risk of field failure during handling and board assembly.
Static Current	ICC ≤ 40 μA max @ VCC = 6.0 V - enables ultra-low-power standby in battery-backed or energy-sensitive designs.

Pinout & Package

74HC03D,652 is housed in a plastic small outline package (SO14), SOT108-1, with 14 leads and 3.9 mm body width. Pin 1 is marked by a notch or dot; pin numbering follows standard counter-clockwise layout from top-left corner.

Pin/Terminal	Circuit Role	Design Meaning
1A, 2A, 3A, 4A	Data input A	First input of each NAND gate - accepts CMOS-level signals; clamp diodes permit overvoltage tolerance with series resistors.
1B, 2B, 3B, 4B	Data input B	Second input of each NAND gate - electrically identical to A inputs; enables dual-input Boolean logic per gate.
1Y, 2Y, 3Y, 4Y	Open-drain output	Active-low NAND output requiring external pull-up - supports voltage translation, bus sharing, and wired-logic expansion.
GND (Pin 7)	Ground reference	0 V return path for all internal circuitry and output sink current - must be low-impedance for noise immunity.
VCC (Pin 14)	Supply voltage	Primary power rail (2.0–6.0 V); powers all four gates and input protection structures - decoupling capacitor required near pin.

Key Features

Feature	Design Value
Wide supply range	2.0 V to 6.0 V operation - eliminates need for separate voltage regulators in mixed-voltage PCBs.
Open-drain outputs	Four independent open-drain outputs - allows direct connection to I²C, SMBus, or shared interrupt lines without contention.
Input clamp diodes	Integrated input clamps - enable safe interfacing to 5 V or higher signals on 3.3 V-powered boards using simple current-limiting resistors.
High noise immunity	Typical VIH/VIL margins >1.3 V @ VCC = 4.5 V - rejects transient coupling in noisy industrial environments.
Latch-up robustness	JESD78 Class II Level B (>100 mA) - prevents destructive latch-up during ESD or supply transients.

Applications

Industrial Bus Interface

I²C Signal Conditioning

Use Scenario: Isolating and combining multiple sensor interrupt lines onto a single microcontroller input in programmable logic controllers.

IC Role / Device Role / Timing Role: Quad NAND acts as active-low wired-OR combiner via open-drain outputs, synchronized to system clock domain.

Use Value: Reduces GPIO count by 4× while maintaining deterministic low-latency response (<29 ns max propagation delay at 4.5 V).

Use Scenario: Level-shifting and buffering SDA/SCL signals between 3.3 V MCU and 5 V EEPROM in embedded instrumentation.

IC Role / Device Role / Timing Role: Open-drain NAND gates replace discrete MOSFET translators, providing bidirectional logic-level adaptation without direction control pins.

Use Value: Eliminates external FETs and bias resistors; preserves I²C timing compliance (t_BUF, t_HD:STA) per specification due to sub-25 ns transition times.

Programmable Logic Expansion

Motor Control Safety Interlock

Use Scenario: Adding custom combinational logic to FPGA I/O banks where LUT resources are constrained.

IC Role / Device Role / Timing Role: Implements NAND-based glue logic (e.g., enable decoding, fault masking) with predictable setup/hold timing.

Use Value: Provides deterministic 8–29 ns propagation delay across voltage/temperature - simplifies static timing analysis versus configurable logic.

Use Scenario: Validating dual-channel safety shutdown signals before enabling H-bridge drivers in BLDC motor controllers.

IC Role / Device Role / Timing Role: NAND gate enforces AND-of-inverted inputs (e.g., ENABLE ∧ !FAULT) with fail-safe open-drain output driving optocoupler LED.

Use Value: Ensures hardware-enforced interlock with <0.4 V VOL @ 5.2 mA - guarantees reliable turn-on of isolation stage under worst-case conditions.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad NAND gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74HCT03D,652	TTL-compatible inputs (VIH = 2.0 V min), otherwise identical pinout, timing, and open-drain structure.	Better suited for legacy 5 V TTL systems or mixed-logic interfacing where input thresholds must match older microcontrollers.	Select when interfacing directly to 5 V TTL outputs or MCUs with weak high-drive capability.
SN74LVC03APW	Lower VCC range (1.65–5.5 V), higher speed (tpd = 4.5 ns @ 3.3 V), but no input clamp diodes.	Preferred in modern low-voltage portable designs; unsuitable for overvoltage-tolerant interfaces without external protection.	Choose for 3.3 V-only systems prioritizing speed and power efficiency, provided input voltage stays within VCC.

Compared with 74HC03D,652, the 74HCT03D,652 eases integration into legacy 5 V logic domains via TTL input thresholds, while SN74LVC03APW trades overvoltage tolerance for faster switching and lower supply headroom - making each optimal for distinct voltage architecture constraints.

FAQ

What is the maximum sink current capability of the 74HC03D,652 outputs?

The 74HC03D,652 open-drain outputs support up to 5.2 mA sink current at VCC = 4.5 V with VOL ≤ 0.33 V, and up to 5.2 mA at VCC = 6.0 V with VOL ≤ 0.4 V. Absolute maximum output current is rated at ±25 mA, but sustained operation above 5.2 mA requires thermal derating per the SO14 package's 10.1 mW/K derating curve above 100 °C.

Can the 74HC03D,652 be used with a 3.3 V supply and 5 V inputs?

Yes - its integrated input clamp diodes allow safe interface to 5 V signals when used with appropriate current-limiting resistors (e.g., 10 kΩ), as confirmed in Section 1 of the datasheet. This enables level translation from 5 V peripherals to 3.3 V logic domains without external components.

How does the open-drain output affect pull-up resistor selection?

Pull-up resistor value must balance rise time and power: lower resistance (e.g., 1–4.7 kΩ) yields faster edges but increases static current; higher values (e.g., 10–50 kΩ) reduce power but extend rise time. For I²C at 400 kHz, 2.2 kΩ is typical; for general-purpose bus arbitration, 4.7 kΩ ensures <1 μs rise time with CL ≤ 50 pF.

Is the 74HC03D,652 pin-compatible with other 74HCxx devices in SO14 packages?

Yes - it shares the standard 14-pin SOIC footprint (SOT108-1) and identical pinout with other quad-gate logic devices like 74HC00 (NAND), 74HC02 (NOR), and 74HC08 (AND). However, function differs: only 74HC03 and 74HCT03 provide open-drain outputs; others have push-pull outputs.
