Nexperia USA Inc. HEF4001BT-Q100J

Overview

HEF4001BT-Q100 from Nexperia is a quad 2-input NOR gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 3.0 V to 15.0 V, featuring CMOS low power dissipation, symmetrical output drive, and input clamp diodes enabling overvoltage-tolerant interfacing in body control modules.

For engineers reviewing the HEF4001BT-Q100 datasheet, HEF4001BT-Q100 pinout, HEF4001BT-Q100 application, or HEF4001BT-Q100 equivalent, key selection criteria include its wide VDD range (3–15 V), guaranteed propagation delay ≤40 ns at 15 V/50 pF, AEC-Q100 Grade 1 qualification, and SO14 package compatibility with legacy 4000-series logic layouts.

Technical Context

The HEF4001BT-Q100 implements four independent 2-input NOR gates using silicon-gate CMOS technology, each with fully static operation and no minimum clock or refresh requirement. Input clamp diodes allow safe interface to signals exceeding VDD when used with current-limiting resistors.

Its logic function follows standard Boolean NOR behavior: output is HIGH only when both inputs are LOW; otherwise output is LOW. Output characteristics are standardized and symmetrical-VOH ≥14.95 V and VOL ≤0.05 V at VDD = 15 V and |IO| < 1 μA-ensuring predictable noise margins across temperature.

Key Specifications

Pinout & Package

FAQ

Is HEF4001BT-Q100 pin-compatible with standard HEF4001B variants?

Yes-HEF4001BT-Q100 uses the same SO14 (SOT108-1) package and identical pinout as non-automotive HEF4001B devices. All 14 pins retain identical functions: inputs (1A–4B), outputs (1Y–4Y), VSS (pin 7), and VDD (pin 14). No PCB redesign is needed for drop-in replacement in existing layouts.

What is the maximum capacitive load the outputs can drive reliably?

The outputs are characterized up to 50 pF load capacitance per gate, with propagation delay specified at CL = 50 pF. Driving >50 pF increases transition time and may cause timing violations; for heavier loads, buffer stages or lower-VDD operation (e.g., 10 V) are recommended to maintain tPLH/tPHL ≤50 ns.

Does HEF4001BT-Q100 support mixed-voltage interfacing (e.g., 3.3 V MCU to 12 V peripheral)?

No-it does not perform level translation. However, its input clamp diodes allow safe connection of 3.3 V logic outputs to its inputs when VDD = 12 V, provided series current-limiting resistors (≥10 kΩ) are used to limit IIK to <±10 mA. Outputs swing rail-to-rail and require external level shifters for 3.3 V MCU inputs.

How does the device behave during power-up or brown-out conditions?

Due to fully static CMOS design, HEF4001BT-Q100 has no power-on reset requirement and retains valid logic states as long as VDD remains above 2.0 V. Below that threshold, outputs enter high-impedance state; no latch-up or undefined behavior occurs. External pull-downs on inputs are recommended for deterministic startup in systems with slow-rising rails.
