Nexperia USA Inc. 74HC03D-Q100J

Overview

74HC03D-Q100 from Nexperia is an automotive-grade quad 2-input NAND gate with open-drain outputs, designed for level-shifting and wired-AND logic in vehicle body control modules. It operates from 2.0 V to 6.0 V, supports -40 °C to +125 °C ambient range, features CMOS-level inputs, and delivers propagation delay as low as 8 ns at VCC = 6.0 V with CL = 50 pF.

For engineers reviewing the 74HC03D-Q100 datasheet, 74HC03D-Q100 pinout, 74HC03D-Q100 application, or 74HC03D-Q100 equivalent, key selection criteria include open-drain output drive capability, AEC-Q100 Grade 1 qualification, input voltage compatibility across supply rails, and static/dynamic power behavior under automotive thermal conditions.

Technical Context

This device implements four independent NAND gates, each with open-drain output topology enabling flexible pull-up configuration and bus arbitration. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.

It complies with JEDEC JESD7A (2.0 V–6.0 V) and JESD8C (2.7 V–3.6 V), supports TTL-level input thresholds only in the 74HCT03 variant, and exhibits latch-up immunity >100 mA per JESD78 Class II Level B.

FAQ

What is the maximum sink current capability of the open-drain outputs?

The 74HC03D-Q100 open-drain outputs support a guaranteed minimum sink current of 5.2 mA at VO = 0.4 V and VCC = 6.0 V, with absolute maximum ratings allowing up to 25 mA continuous output current. This enables direct driving of LEDs or optocouplers without external transistors in most automotive I/O applications.

Can this device interface safely with 12 V signals?

Yes - input clamp diodes permit safe connection to voltages up to VCC + 0.5 V. When used with a series current-limiting resistor (e.g., 10 kΩ), it can reliably interface with 12 V signals while maintaining integrity of the internal CMOS structure and meeting AEC-Q100 stress limits.

Does the 74HC03D-Q100 require external pull-up resistors on its outputs?

Yes - all four outputs are open-drain and require external pull-up resistors to define HIGH-level voltage and provide current sourcing. Typical values range from 1 kΩ (for fast rise times in low-noise environments) to 10 kΩ (for reduced power consumption in battery-sensitive modules).

How does the propagation delay vary across temperature and supply voltage?

Propagation delay increases with lower VCC and higher temperature: at VCC = 2.0 V it reaches 145 ns (max) over -40 °C to +125 °C, while at VCC = 6.0 V it remains ≤25 ns (max) across the full automotive range. This behavior is fully characterized in Table 7 of the datasheet and validated per AEC-Q100 test conditions.
