Product details
Overview
74HC03DB,112 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 digital systems. 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 thresholds.
For engineers reviewing the 74HC03DB,112 datasheet, 74HC03DB,112 pinout, 74HC03DB,112 application, or 74HC03DB,112 equivalent, key selection criteria include open-drain output drive capability (IO = −25 mA), input clamp diode support for overvoltage-tolerant interfacing, static current consumption below 40 μA at VCC = 6.0 V, and SO14 package compatibility with legacy 74-series footprints.
Technical Context
The 74HC03DB,112 implements four independent NAND gates, each with true open-drain output stage enabling external pull-up configuration for voltage-level flexibility and wired-logic implementation. Its inputs incorporate integrated clamp diodes, allowing safe connection 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, supports TTL-compatible operation via the 74HCT03 variant, and exhibits high noise immunity with VIH ≥ 4.2 V and VIL ≤ 1.8 V at VCC = 6.0 V for the HC version.
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 mixed-voltage signal interfacing |
| Supply Voltage Range | 2.0 V to 6.0 V - supports battery-powered, 3.3 V, and 5 V logic domains without level shifters |
| Propagation Delay | 8 ns (typ) at VCC = 6.0 V, CL = 50 pF - ensures timing-critical combinational logic performance |
| Output Drive | −25 mA sink current - directly drives LEDs, MOSFET gates, or standard TTL loads with external pull-up |
| Input Clamp Diodes | Integrated - permits safe interface to voltages > VCC using series current-limiting resistors |
| Operating Temperature | −40 °C to +125 °C - qualified for industrial and extended-temperature embedded control environments |
| Static Supply Current | ≤ 40 μA at VCC = 6.0 V - enables ultra-low-power standby in always-on subsystems |
Pinout & Package
74HC03DB,112 is supplied in SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | Input A (Gate 1–4) | First input of each NAND gate; accepts CMOS-level signals up to VCC + 0.5 V with clamping |
| 2, 5, 10, 13 | Input B (Gate 1–4) | Second input of each NAND gate; electrically identical to Pin A inputs |
| 3, 6, 8, 11 | Output Y (Gate 1–4) | Open-drain output - requires external pull-up resistor; sinks current only, no active high drive |
| 7 | GND | Ground reference for all inputs, outputs, and internal circuitry; must be low-impedance |
| 14 | VCC | Positive supply rail; decoupling capacitor (100 nF) recommended adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| Open-drain output architecture | Enables direct wired-AND bus topology and voltage-level translation between 1.8 V, 3.3 V, and 5 V domains |
| Input clamp diodes | Permits robust interfacing to signals exceeding VCC (e.g., 12 V sensor outputs) using simple series resistors |
| High noise immunity | VIH/VIL margins exceed 40% of VCC across full voltage range - resists EMI-induced glitches in noisy industrial settings |
| 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 and CDM > 1000 V - reduces handling sensitivity and improves board-level reliability |
Applications
| I²C Bus Interface | Industrial Sensor Hub |
|---|---|
Use Scenario: Driving SDA/SCL lines in multi-master I²C systems with mixed-voltage peripherals. IC Role / Device Role / Timing Role: Open-drain NAND acts as bidirectional bus buffer and voltage translator between 3.3 V microcontroller and 5 V EEPROM. Use Value: Eliminates need for discrete MOSFET translators; supports standard I²C rise-time compliance with single pull-up per line. | Use Scenario: Aggregating fault signals from multiple 24 V industrial sensors into a 3.3 V FPGA input. IC Role / Device Role / Timing Role: NAND gate configured as active-low OR (via De Morgan) to combine multiple alarm outputs onto one interrupt line. Use Value: Input clamp diodes allow direct 24 V signal conditioning with 22 kΩ series resistors; open-drain output interfaces safely to FPGA's 3.3 V tolerant pin. |
| LED Matrix Driver | Legacy System Glue Logic |
Use Scenario: Row/column addressing in multiplexed LED displays requiring high-current sinking capability. IC Role / Device Role / Timing Role: NAND output drives cathode rows directly; external 10 kΩ pull-up defines logic HIGH, while gate sinks up to 25 mA per segment. Use Value: Reduces component count vs. discrete transistor arrays; propagation delay < 10 ns maintains display refresh integrity at >1 kHz scan rates. | Use Scenario: Adapting legacy 5 V TTL control signals to modern 3.3 V microcontroller GPIO with level shifting. IC Role / Device Role / Timing Role: NAND gate used as inverter + level shifter: 5 V input → open-drain output pulled to 3.3 V, generating clean 3.3 V logic levels. Use Value: Avoids dedicated level-shifter ICs; input clamps protect against 5 V overshoot on 3.3 V system; static current < 2 μA minimizes power overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NAND gate with open-drain applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC03D,653 | Same SO14 package, identical electrical specs, but marked for tape-and-reel delivery (not tube); same -40 °C to +125 °C rating | No functional difference; suitable for automated SMT assembly where reel packaging is required | Select when production volume demands machine placement compatibility and consistent reel-based logistics |
| SN74LVC03APWR | TI part in TSSOP14; 1.65–5.5 V supply; lower VIL/VIH thresholds; 24 mA sink; no input clamp diodes | Lacks clamp diodes - cannot safely interface to voltages > VCC without external protection; optimized for 1.8/3.3 V systems only | Choose only for pure 3.3 V or dual-supply 1.8 V/3.3 V designs where clamp diodes are unnecessary and lower voltage operation is mandatory |
Compared with 74HC03DB,112, the 74HC03D,653 offers identical functionality in reel format for SMT lines, while SN74LVC03APWR trades clamp diode safety and 6 V tolerance for lower-voltage optimization and tighter logic thresholds - making the DB,112 preferable for mixed-voltage, ruggedized, or legacy 5 V system integration.

FAQ
What is the maximum sink current per output of the 74HC03DB,112?
The 74HC03DB,112 supports a maximum DC output sink current of −25 mA per open-drain output, verified under recommended operating conditions (VCC = 6.0 V, Tamb = 25 °C). This rating applies continuously within thermal limits; derating is required above 100 °C per the 10.1 mW/K Ptot derating curve for the SO14 package.
Can the 74HC03DB,112 interface directly with 12 V signals?
Yes - its inputs include integrated clamp diodes that safely conduct excess voltage to VCC or GND. When paired with a series current-limiting resistor (e.g., 10 kΩ for 12 V → VCC = 5 V), it tolerates input voltages up to VCC + 0.5 V without damage, enabling direct connection to higher-voltage sensors or legacy systems.
Is the 74HC03DB,112 pin-compatible with standard 74LS03 or 74F03 devices?
Yes - it uses the industry-standard SO14 pinout matching 74LS03, 74F03, and other 74-series quad NANDs. However, output behavior differs: 74HC03DB,112 has open-drain outputs requiring external pull-ups, whereas LS/F variants have totem-pole outputs. Direct replacement is electrically valid only when pull-up resistors are added.
Does the 74HC03DB,112 support 1.8 V logic operation?
No - the minimum recommended supply voltage is 2.0 V per JEDEC JESD7A. At 1.8 V, input thresholds become undefined, propagation delay increases significantly (>200 ns), and static current may rise unpredictably. For 1.8 V systems, consider LVC-family alternatives like SN74LVC03A, which is specified down to 1.65 V.
