Product details
Overview
74HCT03D-Q100 from Nexperia is a quad 2-input NAND gate IC with open-drain outputs, designed for automotive logic-level translation and wired-AND bus interfacing. It operates from 4.5 V to 5.5 V, delivers TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), supports -40 °C to +125 °C ambient range, and features AEC-Q100 Grade 1 qualification for under-hood control modules.
For engineers reviewing the 74HCT03D-Q100 datasheet, 74HCT03D-Q100 pinout, 74HCT03D-Q100 application, or 74HCT03D-Q100 equivalent, this device serves as a robust, temperature-stable logic gate for CAN transceiver enable control, LIN bus pull-up management, and multi-sensor interrupt arbitration in automotive ECUs.
Technical Context
This device implements four independent 2-input NAND gates, each with an open-drain output stage enabling wired-OR/wired-AND configurations and level-shifting across voltage domains. Input clamp diodes allow safe interface 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 CMOS-compatible output drive capability (IO = −5.2 mA at VCC = 6.0 V), and maintains high noise immunity (typical VIH–VIL margin > 1.2 V at 5 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND with open-drain outputs - enables wired-AND bus topology and I²C-style multi-master arbitration |
| 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 TTL-level signal recognition at 5 V |
| Propagation Delay | 12 ns typ (VCC = 4.5 V, CL = 50 pF) - supports >20 MHz toggle rates in timing-critical sensor interfaces |
| Output Drive | −5.2 mA sink at VOL ≤ 0.4 V - sufficient to drive 10 kΩ pull-up on 5 V bus with <0.4 V low-state drop |
| Operating Temperature | −40 °C to +125 °C - qualified for engine control unit (ECU) and transmission control module (TCM) placement |
| AEC-Q100 Grade | Grade 1 - certified for automotive applications per AEC-Q100 Rev G with full stress testing |
Pinout & Package
74HCT03D-Q100 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, surface-mount compatible.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A | Data input A of gate n | First input of each NAND gate; accepts TTL-level signals up to VCC |
| 1B, 2B, 3B, 4B | Data input B of gate n | Second input of each NAND gate; internally clamped to prevent overvoltage damage |
| 1Y, 2Y, 3Y, 4Y | Open-drain output of gate n | Active-low output requiring external pull-up; supports bus sharing and voltage translation |
| 7 | GND | Ground reference (0 V); must be low-impedance connection for noise immunity |
| 14 | VCC | Positive supply (4.5–5.5 V); decoupling capacitor (100 nF) required near pin |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use including thermal cycling, humidity bias, and ESD stress per Rev G requirements |
| Open-drain outputs with clamp diodes | Enables safe interface to voltages > VCC using series resistors; eliminates need for external protection diodes |
| TTL-compatible inputs | Accepts standard 5 V TTL logic levels without level shifters - reduces BOM count in legacy automotive designs |
| High noise immunity | Typical noise margin >1.2 V at 5 V supply - suppresses false triggering from EMI in engine bay environments |
| Low static power | ICC ≤ 2.0 μA typical at VCC = 5.5 V - minimizes quiescent current in always-on vehicle subsystems |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
Use Scenario: Arbitrating multiple sensor fault interrupts onto a shared diagnostic line. IC Role / Device Role / Timing Role: Wired-AND combiner for active-low fault flags from oxygen sensors, knock sensors, and MAP sensors. Use Value: Single 74HCT03D-Q100 replaces discrete diode-OR network, reducing board area by 65 % and eliminating forward-voltage mismatch errors. |
Use Scenario: Enabling/disabling LIN transceiver pull-up resistors based on master node status. IC Role / Device Role / Timing Role: Open-drain NAND gate controlling pull-up enable line to match LIN physical layer specification. Use Value: Ensures precise 5 V pull-up activation only when master is active, preventing bus contention during sleep mode. |
| CAN Transceiver Interface | Instrument Cluster Display Backlight Control |
Use Scenario: Generating CAN standby mode enable signal from microcontroller GPIO and ignition status. IC Role / Device Role / Timing Role: Logic gate combining MCU control and vehicle power state to assert CAN transceiver STB pin. Use Value: Guarantees transceiver enters low-power standby only when both conditions are met - prevents unintended wake-up. |
Use Scenario: Driving LED backlight enable lines with adjustable dimming via PWM injection at NAND input. IC Role / Device Role / Timing Role: Open-drain gate accepting PWM-modulated input to modulate average current through external FET driver. Use Value: Enables software-controlled brightness scaling without dedicated PWM controller, saving MCU resources. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT03PW-Q100 | TSSOP14 package (SOT402-1); 4.4 mm body width; 0.65 mm lead pitch | Higher board density; lower thermal resistance (7.3 mW/K derating above 81 °C) | Select for space-constrained PCBs where reflow profile supports fine-pitch TSSOP handling |
| SN74HCT03QPWRQ1 | Texas Instruments part; identical logic function and AEC-Q100 Grade 1; SOIC-14 package | Same pinout but different ESD rating (HBM 4 kV vs Nexperia's 2 kV) and propagation delay (15 ns typ) | Choose when TI supply chain alignment or higher HBM ESD margin is prioritized over minimal propagation delay |
Compared with 74HCT03PW-Q100, the D-package version offers easier optical inspection and hand-soldering; versus SN74HCT03QPWRQ1, it provides faster switching (12 ns vs 15 ns) and tighter VOL (0.26 V vs 0.4 V at 4 mA), critical for low-drop bus signaling.

FAQ
What is the maximum sink current per output at 125 °C?
At +125 °C ambient and VCC = 5.5 V, the 74HCT03D-Q100 guarantees a maximum output low voltage (VOL) of 0.4 V with 4.0 mA sink current. Absolute maximum rated output current remains −25 mA, but sustained operation above 4.0 mA is not characterized across the full temperature range and requires thermal derating per the datasheet's Ptot curve.
Can this device interface directly with 3.3 V microcontrollers?
No - the 74HCT03D-Q100 has TTL-compatible inputs requiring VIH ≥ 2.0 V, but its VCC must be 4.5–5.5 V. To interface with 3.3 V MCUs, use a level-shifting buffer or configure the MCU's output to drive the gate with ≥2.0 V high-level signals while ensuring the MCU I/O tolerates 5 V on input (if enabled as input). Direct 3.3 V VCC operation is not supported.
Why does the datasheet specify two different propagation delay values for VCC = 4.5 V?
The 74HCT03D-Q100 lists tpd = 12 ns (typ) and 30 ns (max) at VCC = 4.5 V because propagation delay varies with load capacitance and process corner. The 12 ns value is measured at CL = 50 pF and 25 °C; the 30 ns maximum covers worst-case corner (slow process, hot temperature, high CL) across the full −40 °C to +125 °C range per AEC-Q100 test conditions.
Is the open-drain output rated for 12 V bus interfacing?
No - the absolute maximum output voltage (VO) is +7 V, and the clamp diodes are rated only for transient excursions above VCC, not continuous 12 V operation. For 12 V bus interfacing, add an external level-shifting transistor or dedicated level translator; the device itself must remain within its 4.5–5.5 V VCC and −0.5 to +7 V VO limits.
