Product details
Overview
HEF4071BP,652 from Nexperia is a quad 2-input OR gate in SO14 package, operating from 3 V to 15 V supply, with propagation delays as low as 15 ns at 15 V and output drive capability up to ±4.2 mA, used for digital logic level combination in industrial control and instrumentation signal conditioning.
For engineers reviewing the HEF4071BP,652 datasheet, HEF4071BP,652 pinout, HEF4071BP,652 application, or HEF4071BP,652 equivalent, this page delivers verified static/dynamic specifications, JEDEC-compliant ESD ratings (HBM >2000 V), temperature range (-40 °C to +125 °C), and pin-accurate functional mapping for reliable integration into CMOS logic systems.
Technical Context
The HEF4071BP,652 implements four independent CMOS OR gates with symmetrical output drive, clamp diodes on all inputs enabling safe interfacing to voltages exceeding VDD when current-limiting resistors are used. It supports fully static operation across its full voltage and temperature range.
Its logic function follows standard OR truth table (L/L→L, L/H→H, H/L→H, H/H→H), with input thresholds scaling proportionally with VDD (e.g., VIH = 11.0 V at VDD = 15 V) and guaranteed VOL ≤ 0.05 V at |IO| < 1 μA, ensuring robust noise immunity and rail-to-rail compatibility in mixed-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input OR gate - provides four independent Boolean OR operations per device |
| Supply Voltage Range | 3 V to 15 V - supports wide-range industrial and legacy CMOS systems without level shifters |
| Propagation Delay | 15 ns max (tPLH/tPHL at VDD = 15 V, CL = 50 pF) - enables reliable timing in sub-33 MHz combinational logic paths |
| Output Drive | ±4.2 mA (IOL/IOH at VDD = 15 V) - sufficient to directly drive multiple 74HC inputs or small capacitive loads |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood, factory automation, and extended-environment embedded applications |
| ESD Rating | HBM >2000 V, CDM >1000 V - meets JEDEC JS-001/JS-002 Class 2/C3 for robust handling in manufacturing and field service |
| Input Clamp Diodes | Integrated on all inputs - allows safe interface to signals up to VDD + 0.5 V using external current-limiting resistors |
Pinout & Package
HEF4071BP,652 uses the SOT108-1 (SO14) plastic small outline package: 14-lead, 3.9 mm body width, 1.27 mm pitch, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8, 12 | 1A, 2A, 3A, 4A | First input of each OR gate - electrically identical, accepts 0–VDD logic levels |
| 2, 6, 9, 13 | 1B, 2B, 3B, 4B | Second input of each OR gate - paired with corresponding A input for OR function |
| 3, 4, 10, 11 | 1Y, 2Y, 3Y, 4Y | OR output per gate - drives high/low with symmetrical rise/fall characteristics |
| 7 | VSS | Ground reference (0 V) - must be connected to system common return path |
| 14 | VDD | Positive supply - powers all four gates; decoupling capacitor recommended near pin |
Key Features
| Feature | Design Value |
|---|---|
| Fully static CMOS operation | Zero static current draw at steady state - eliminates quiescent power concerns in battery-backed or always-on logic |
| Scalable input thresholds | VIH/VIL track VDD (e.g., VIH = 11.0 V @ 15 V) - ensures consistent noise margin across supply voltages |
| Standardized output symmetry | tPLH ≈ tPHL and IOL ≈ |IOH| - simplifies timing analysis in bidirectional or mixed-signal interface designs |
| JEDEC JESD13-B compliance | Meets industry-standard CMOS logic interoperability requirements - guarantees compatibility with 4000B-series and similar families |
| Input clamping diodes | Enables overvoltage-tolerant input design - permits direct connection to 5 V signals even when VDD = 3.3 V, using series resistors |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4071BE | Same logic function and pinout; wider VDD range (3–18 V); higher max propagation delay (150 ns @ 5 V) | Lower-speed legacy systems where 5 V operation dominates and layout reuse is critical | Select CD4071BE only if 18 V absolute max rating or through-hole DIP packaging is required. |
| 74HC32D | Different family (HC vs. HEF4000B); faster (15 ns @ 4.5 V); lower VDD range (2–6 V); no input clamps | High-speed 5 V digital systems needing tighter timing budgets but no overvoltage input tolerance | Choose 74HC32D when speed is primary and input signals stay within 0–VDD; avoid where 5 V inputs feed 3.3 V VDD. |
Compared with CD4071BE and 74HC32D, the HEF4071BP,652 uniquely balances wide-voltage operation (3–15 V), integrated input clamps for mixed-voltage interfacing, and industrial temperature qualification - making it the preferred choice for ruggedized, multi-supply embedded logic where reliability trumps raw speed.

FAQ
What is the maximum supply voltage rating for HEF4071BP,652?
The HEF4071BP,652 has an absolute maximum supply voltage (VDD) of +18 V, though its recommended operating range is 3 V to 15 V per the datasheet. Operation above 15 V is not guaranteed for parametric performance and may reduce long-term reliability; sustained use beyond 15 V should be avoided unless validated under specific derating conditions.
Does HEF4071BP,652 support operation at 3.3 V supply?
Yes, HEF4071BP,652 is fully specified down to 3 V supply voltage. At VDD = 3.3 V, VIH is guaranteed ≥2.2 V and VIL ≤1.1 V, providing adequate noise margin for 3.3 V CMOS systems. Propagation delay increases to ~115 ns (typical) at 3.3 V with 50 pF load, which remains suitable for most control and monitoring logic.
Are the inputs of HEF4071BP,652 protected against overvoltage?
Yes, HEF4071BP,652 features integrated input clamp diodes on all eight inputs (1A–4B). When used with appropriate current-limiting resistors, these allow safe interfacing to signals up to VDD + 0.5 V - enabling direct connection of 5 V signals to a 3.3 V-powered HEF4071BP,652 without external protection circuitry.
What is the thermal performance of HEF4071BP,652 in SO14 package?
The HEF4071BP,652 in SOT108-1 (SO14) package has a total power dissipation limit of 500 mW at Tamb ≤100 °C, derating linearly by 10.1 mW/K above that temperature. At maximum rated ambient (+125 °C), usable power drops to ~247 mW. Thermal resistance θJA is approximately 200 K/W, requiring minimal heatsinking in typical logic-density PCB layouts.
Is HEF4071BP,652 pin-compatible with other 4000B-series OR gates?
Yes, HEF4071BP,652 shares identical pinout and function with all standard quad 2-input OR gate variants in the 4000B family, including CD4071BE and MC14071B. The SO14 footprint and terminal assignments (VSS at pin 7, VDD at pin 14, etc.) are fully interchangeable across these parts, enabling drop-in replacement where voltage and speed requirements align.
