Product details
Overview
HEF4071BT-Q100 from Nexperia is a quad 2-input OR gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 3–15 V, propagation delay as low as 15 ns at 10 V, and symmetrical CMOS output drive (±1.6 mA at 10 V). It serves as a logic-level combiner in vehicle body control modules, lighting controllers, and power distribution supervisors.
For engineers reviewing the HEF4071BT-Q100 datasheet, HEF4071BT-Q100 pinout, HEF4071BT-Q100 application, or HEF4071BT-Q100 equivalent, this page delivers verified functional identity, SO14 pin mapping, automotive-grade thermal and ESD specs (HBM >2000 V, CDM >1000 V), and direct substitution guidance against industry-standard 4000-series OR gates.
Technical Context
This device implements four independent CMOS OR logic functions with clamp diodes on all inputs, enabling safe interfacing to voltages exceeding VDD via external current-limiting resistors. Each gate follows the Boolean function Y = A + B, with defined HIGH/LOW thresholds scaling linearly with VDD (e.g., VIH = 11.0 V at VDD = 15 V).
It operates statically across 3–15 V supply, supports dynamic loading up to 50 pF, and exhibits temperature-invariant output voltage levels (VOH ≥ 14.95 V, VOL ≤ 0.05 V at 15 V) over its full -40 °C to +125 °C automotive ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input OR gate (Y = A + B per channel) |
| Supply Voltage Range | 3 V to 15 V - supports 5 V, 10 V, and 15 V system rails without level shifting |
| Propagation Delay | 15 ns typical (tPLH/tPHL @ 10 V, CL = 50 pF) - enables reliable timing in <66 MHz combinational paths |
| Output Drive | ±1.6 mA @ 10 V - sufficient to drive 10 LSTTL loads or 50 pF capacitive bus |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets AEC-Q100 stress requirements for assembly and field operation |
| Ambient Temperature | -40 °C to +125 °C - qualified for under-hood and powertrain-adjacent locations |
| Input Clamp Diodes | Integrated on all 8 inputs - permits direct connection to 24 V signals using series resistors |
Pinout & Package
HEF4071BT-Q100 is housed in a plastic small outline package (SO14), SOT108-1, with 14 leads, 3.9 mm body width, and standard 1.27 mm lead pitch. The package is RoHS-compliant and rated for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8, 12 | 1A, 2A, 3A, 4A | First input of each OR gate - accepts TTL- or CMOS-compatible logic levels |
| 2, 6, 9, 13 | 1B, 2B, 3B, 4B | Second input of each OR gate - internally clamped to VSS/VDD for overvoltage tolerance |
| 3, 4, 10, 11 | 1Y, 2Y, 3Y, 4Y | OR output per gate - rail-to-rail CMOS swing with symmetrical sourcing/sinking capability |
| 7 | VSS | Ground reference (0 V) - must be low-impedance return path for all gates |
| 14 | VDD | Positive supply - powers all four gates; decoupling capacitor required within 10 mm |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125 °C ambient, including temperature cycling and HTOL testing |
| Input clamp diodes | Enables interface to 24 V sensors or switches without external protection components |
| CMOS low-power static operation | IDD ≤ 30 μA max at 15 V and +125 °C - reduces quiescent current in always-on modules |
| High noise immunity | Typical noise margin >40% of VDD across full temperature range - resists EMI in engine bays |
| Standardized output characteristics | Matched rise/fall times and drive strength across all four channels - simplifies timing analysis |
Applications
| Body Control Module (BCM) | LED Lighting Controller |
|---|---|

Use Value: Symmetrical output drive ensures equal rise/fall times on bidirectional H-bridge enable lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4071BE | Non-automotive, commercial temp range (-55 °C to +125 °C), no AEC-Q100 qualification, lower ESD rating (HBM ~200 V) | Not suitable for production automotive ECUs; acceptable for lab prototypes or non-safety systems | Select only if cost sensitivity outweighs qualification requirements and environmental robustness |
| 74HC32PW,118 | Higher speed (tPD ≈ 7 ns @ 5 V), narrower VDD range (2–6 V), no input clamps, lower drive (±4 mA @ 5 V) | Requires external clamping for >6 V inputs; unsuitable for 12/24 V automotive sensor interfaces | Prefer where 5 V-only systems demand faster switching and board space is constrained |
Compared with CD4071BE and 74HC32PW,118, the HEF4071BT-Q100 uniquely combines AEC-Q100 Grade 1 qualification, 3–15 V operation with integrated input clamps, and guaranteed performance at +125 °C - making it the only drop-in solution for 12/24 V automotive logic aggregation without redesign.

FAQ
Is HEF4071BT-Q100 pin-compatible with legacy 4071 devices?
Yes - it uses the standard SO14 pinout matching CD4071, MC14071, and 74C71. Pin 1 is 1A, Pin 2 is 1B, Pin 3 is 1Y, continuing through Pin 14 (VDD), with identical VSS (Pin 7) and gate input/output assignments. No PCB redesign is needed for drop-in replacement.
What is the maximum capacitive load this OR gate can drive reliably?
The device is characterized up to 50 pF load capacitance per output, with propagation delay specified at that value. Driving >50 pF increases tPD nonlinearly (e.g., +0.23 ns/pF at 10 V); for >100 pF, consider buffering or using a higher-drive logic family like 74AC.
Can HEF4071BT-Q100 interface directly with 24 V sensors?
Yes - its input clamp diodes allow direct connection to 24 V signals when used with a series current-limiting resistor (e.g., 10 kΩ limits IIK to <2.4 mA at 24 V), satisfying the ±10 mA absolute maximum clamp current rating.
Does this part require external decoupling capacitors?
Yes - a minimum 100 nF ceramic capacitor must be placed between VDD (Pin 14) and VSS (Pin 7), located within 10 mm of the package. For systems with fast-switching loads, add a 1–10 μF bulk capacitor nearby to suppress supply rail sag during simultaneous output transitions.
