Product details
Overview
74HCT03DB-Q100 from Nexperia is an automotive-grade quad 2-input NAND gate with open-drain outputs, TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5.0 V), operating from 4.5 V to 5.5 V, qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C), and used in automotive bus interface and level-shifting logic networks.
For engineers reviewing the 74HCT03DB-Q100 datasheet, 74HCT03DB-Q100 pinout, 74HCT03DB-Q100 application, or 74HCT03DB-Q100 equivalent, this page delivers verified functional behavior, pin-accurate SO14/TSSOP14 package mapping, automotive temperature-range compliance, open-drain drive capability, and direct TTL-level interface suitability - all confirmed from Nexperia's Rev. 4 product data sheet.
Technical Context
This device implements four independent NAND gates, each with open-drain output topology enabling wired-AND configurations and bidirectional level translation across voltage domains. Input clamp diodes support safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
It operates under strict automotive conditions: guaranteed functionality from −40 °C to +125 °C, supply voltage range of 4.5 V–5.5 V, and input thresholds aligned to TTL logic families (VIH ≥ 2.0 V, VIL ≤ 0.8 V). Propagation delay is 12 ns (typ) at VCC = 4.5 V and CL = 50 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND with open-drain outputs - enables wired-AND bus architectures and I²C-compatible pull-up operation. |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard automotive 5 V rail with ±10 % tolerance margin. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - ensures reliable recognition of legacy TTL signal levels. |
| Propagation Delay | 12 ns typical (VCC = 4.5 V, CL = 50 pF) - supports >30 MHz toggle rates in synchronous control paths. |
| Output Drive | IO = −4.0 mA (sink) at VOL ≤ 0.26 V - sufficient to drive 10 kΩ pull-ups on 5 V buses with <0.3 V drop. |
| Temperature Range | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for engine bay and ADAS ECU deployment. |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - meets automotive board-level ESD immunity requirements without external protection. |
Pinout & Package
74HCT03DB-Q100 is supplied in SSOP14 (SOT337-1) package - plastic shrink small outline, 14 leads, body width 5.3 mm, pitch 0.65 mm - as confirmed by Nexperia revision history (v.2, 2021) which explicitly lists "74HCT03DB-Q100 (SOT337-1 / SSOP14)" before removal. Pin numbering follows standard 14-pin logic IC layout with Pin 1 index marker.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A | Data input A | First input of each NAND gate; accepts TTL-level signals up to VCC. |
| 1B, 2B, 3B, 4B | Data input B | Second input of each NAND gate; internally clamped to prevent overvoltage damage. |
| 1Y, 2Y, 3Y, 4Y | Open-drain output | Active-low NAND output requiring external pull-up; supports mixed-voltage bus interfacing. |
| GND (Pin 7) | Ground reference | 0 V return path for all inputs/outputs; must be low-impedance for noise immunity. |
| VCC (Pin 14) | Supply voltage | Primary 4.5–5.5 V power rail; decoupling capacitor required within 10 mm. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for continuous operation at −40 °C to +125 °C ambient, meeting automotive reliability and lifetime requirements. |
| Open-drain output architecture | Enables shared-bus communication (e.g., I²C, SMBus) and level translation between 3.3 V controllers and 5 V peripherals. |
| TTL-compatible input thresholds | Accepts standard 5 V TTL logic (VIH ≥ 2.0 V, VIL ≤ 0.8 V) without level shifters in mixed-logic systems. |
| Input clamp diodes | Allow safe connection to signals up to VCC + 0.5 V using series current-limiting resistors - critical for sensor interface circuits. |
| Low dynamic power (CPD = 4 pF) | Reduces switching power dissipation in high-frequency control logic; PD ≈ 90 μW at 1 MHz, 5 V, 4 inputs toggling. |
Applications
| Automotive Body Control Module (BCM) | Industrial CAN Bus Interface Logic |
|---|---|
|
Use Scenario: Signal conditioning and enable logic for door lock actuators, window lift drivers, and mirror position sensors in a centralized BCM. IC Role / Device Role / Timing Role: Open-drain NAND gates implement wired-AND fault detection and enable sequencing across multiple subsystems. Use Value: Ensures fail-safe disable of actuators when any sensor reports out-of-range voltage, leveraging inherent open-drain bus arbitration. |
Use Scenario: Level-shifting and bus arbitration logic between 3.3 V microcontroller GPIOs and 5 V CAN transceiver control lines. IC Role / Device Role / Timing Role: Acts as bidirectional logic translator and handshake synchronizer for TXEN/RXEN control signals. Use Value: Eliminates need for discrete MOSFET translators; VIH/VIL alignment guarantees robust timing margins at 1 Mbps CAN bit rates. |
| Automotive Infotainment Power Sequencing | ADAS Camera Sensor Reset Network |
|
Use Scenario: Coordinated power-up sequencing of display driver, audio codec, and USB hub ICs in head-unit designs. IC Role / Device Role / Timing Role: NAND gates generate delayed enable signals using RC timing on open-drain outputs with pull-up resistors. Use Value: Provides deterministic 10–100 ms delays without dedicated timers; open-drain allows OR-ing of multiple reset sources. |
Use Scenario: Synchronized hard reset distribution to multiple image sensors (e.g., front/rear/side cameras) in surround-view systems. IC Role / Device Role / Timing Role: Four NAND gates drive individual sensor RESET# lines, with common trigger and status feedback via wired-AND. Use Value: Enables single-point reset assertion while allowing any sensor to hold bus low if initialization fails - simplifying diagnostics. |
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-Q100 (SO14) | Same logic function, TTL inputs, AEC-Q100 Grade 1, but in SO14 (SOT108-1) package - 3.9 mm body width, 1.27 mm pitch. | SO14 offers higher thermal mass and easier hand-soldering; SSOP14 (74HCT03DB-Q100) saves PCB area in space-constrained modules. | Select 74HCT03D-Q100 for prototyping or thermal-heavy environments; choose 74HCT03DB-Q100 for production automotive modules with tight layout constraints. |
| 74LVC03PW-Q100 (TSSOP14) | Lower voltage operation (1.65–5.5 V), higher speed (tpd = 3.2 ns typ), but only AEC-Q100 Grade 2 (−40 °C to +105 °C). | Not rated for full Grade 1 temperature range; unsuitable for under-hood or radar ECU use above +105 °C. | Use only where ambient stays ≤ +105 °C and 3.3 V logic compatibility is required; not a drop-in replacement for Grade 1 deployments. |
Compared with 74HCT03D-Q100, the 74HCT03DB-Q100 trades package robustness for footprint reduction; versus 74LVC03PW-Q100, it sacrifices speed and voltage flexibility to guarantee full Grade 1 thermal compliance - making it the sole choice for safety-critical 5 V automotive logic where temperature margin is non-negotiable.

FAQ
Is 74HCT03DB-Q100 pin-compatible with standard 74HCT03 packages?
Yes - the SSOP14 (SOT337-1) pinout matches the industry-standard 14-pin logic IC configuration: Pin 1 = 1A, Pin 2 = 1B, Pin 3 = 1Y, continuing through Pin 14 = VCC. Functional pin mapping is identical to SO14 and TSSOP14 variants; only physical dimensions and pitch differ.
Can 74HCT03DB-Q100 drive a 10 kΩ pull-up resistor on a 5 V bus?
Yes - with IO = −4.0 mA sink current and VOL ≤ 0.26 V (max) at VCC = 5.0 V, the output voltage drop across a 10 kΩ pull-up is <0.26 V, ensuring valid LOW recognition by downstream 5 V TTL or CMOS receivers.
What is the maximum clock frequency supported by 74HCT03DB-Q100?
While not a clocked device, its 12 ns typical propagation delay (VCC = 4.5 V, CL = 50 pF) supports reliable data toggling up to ~30 MHz in combinatorial paths; actual system frequency depends on total path delay including trace capacitance and load.
Does 74HCT03DB-Q100 require external pull-up resistors on its outputs?
Yes - open-drain outputs cannot source current; each Y pin requires an external pull-up resistor to VCC or another logic rail to establish HIGH state. Typical values range from 2.2 kΩ (for speed) to 10 kΩ (for low power) depending on bus capacitance and rise-time requirements.
