Nexperia USA Inc. HEF4001BT-Q100/AUJ

Overview

HEF4001BT-Q100 from Nexperia is a quad 2-input NOR gate IC qualified to AEC-Q100 Grade 1, operating from -40 °C to +125 °C with supply voltage range 3.0 V to 15.0 V. It features CMOS low power dissipation, symmetrical output drive (±1.1 mA at 5 V), and input clamp diodes enabling overvoltage-tolerant interfacing in automotive 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, automotive-grade temperature capability, NOR logic function per gate, SO14 package compatibility, and I/O clamping for robustness in noisy vehicle environments.

Technical Context

This device implements four independent 2-input NOR gates using standard CMOS process technology, with fully static operation and no minimum clock or refresh requirement. Each gate exhibits identical input thresholds (VIH = 11.0 V, VIL = 4.0 V at VDD = 15 V) and rail-to-rail output swing (VOH ≥ 14.95 V, VOL ≤ 0.05 V).

Propagation delay scales linearly with load capacitance: tPHL/tPLH = 12 + 0.16 × CL (ns) at 15 V, supporting timing-critical combinatorial logic in engine control units and lighting controllers where deterministic gate delay is essential.

Key Specifications

Pinout & Package

FAQ

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

Yes - HEF4001BT-Q100 uses the same SO14 (SOT108-1) footprint and pinout as non-automotive HEF4001B devices, including identical terminal assignments for VDD (pin 14), VSS (pin 7), and all gate inputs/outputs. No PCB redesign is needed for drop-in replacement in existing layouts.

What is the maximum capacitive load this device can drive reliably?

The HEF4001BT-Q100 is characterized up to 50 pF load capacitance per output, with propagation delay extrapolated as tPHL/tPLH = 12 + 0.16 × CL (ns) at 15 V. Driving loads beyond 50 pF increases delay unpredictably and may cause excessive dynamic power dissipation or output ringing.

Does this part support 3.3 V logic interfacing?

No - while the device operates down to 3.0 V supply, its input thresholds scale with VDD (e.g., VIH = 11.0 V at 15 V). At 3.3 V VDD, VIH ≈ 2.3 V and VIL ≈ 1.0 V, making it incompatible with standard 3.3 V LVTTL or LVCMOS logic levels without level translation.

How does the input clamping affect external resistor selection?

Clamp diodes allow series resistors to limit current when interfacing with voltages up to VDD + 0.5 V. For a 13.5 V signal into a 5 V-powered device, a 10 kΩ resistor limits peak clamp current to <1 mA, well within the ±10 mA absolute maximum rating specified in Table 4.
