Nexperia USA Inc. 74HC4075D-Q100J

Overview

74HC4075D-Q100 from Nexperia is a triple 3-input OR gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with CMOS-level inputs, 6 V absolute max supply voltage, and propagation delay as low as 8 ns at VCC = 6 V. It performs logical OR across three independent 3-input channels in engine control units, body electronics, and ADAS sensor interface logic.

For engineers reviewing the 74HC4075D-Q100 datasheet, 74HC4075D-Q100 pinout, 74HC4075D-Q100 application, or 74HC4075D-Q100 equivalent, this page delivers verified pin functions, automotive-grade static/dynamic specifications, SO14 package thermal derating data, and validated functional alternatives for logic-level translation and redundancy-critical OR-tree implementations.

Technical Context

This device implements three independent 3-input OR gates using standard CMOS silicon technology, with input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Each gate exhibits symmetrical HIGH/LOW output drive capability up to ±4.0 mA at VCC = 4.5 V.

It supports dual logic families: 74HC4075D-Q100 accepts CMOS-level inputs (VIH ≥ 3.15 V at VCC = 4.5 V), while its 74HCT variant accepts TTL-compatible inputs (VIH ≥ 2.0 V). Propagation delay varies with supply voltage and load-8–30 ns over VCC = 4.5–6.0 V and CL = 50 pF.

FAQ

Can 74HC4075D-Q100 operate at 3.3 V supply?

Yes. The device is fully specified from 2.0 V to 6.0 V, including 3.3 V operation. At VCC = 3.3 V, VIH is guaranteed ≥2.1 V and VOL ≤0.26 V at IO = 4.0 mA, ensuring interoperability with 3.3 V microcontrollers and FPGAs in modern automotive domains.

What is the maximum capacitive load it can drive reliably?

74HC4075D-Q100 is characterized up to 50 pF load capacitance per output, with tpd and tt values guaranteed in that condition. Driving >50 pF may increase propagation delay and transition time beyond datasheet limits; for heavier loads, add a buffer stage or reduce trace length and parallel capacitance.

Does it support hot-swap or live-insertion?

No. While input clamp diodes protect against overvoltage, the device lacks explicit hot-swap circuitry such as power-on reset, slew-rate control, or back-drive protection. It must be powered and stabilized before applying input signals to avoid latch-up or undefined output states.

How does its ESD rating compare to standard industrial logic?

With HBM >2000 V and CDM >1000 V, its ESD robustness exceeds typical industrial-grade 74HC devices (often HBM ~2000 V but CDM <500 V), reflecting enhanced process hardening for automotive assembly lines and in-vehicle electrostatic environments.
