Product details
Overview
HEF4011BT,652 from Nexperia is a quad 2-input CMOS NAND gate IC operating from 3 V to 15 V supply, featuring symmetrical output drive (±4.2 mA at 15 V), 14-pin SO14 package, and guaranteed operation from −40 °C to +125 °C. It integrates input clamp diodes for overvoltage-tolerant interfacing and is used in digital logic control, power sequencing, and industrial sensor interface circuits.
For engineers reviewing the HEF4011BT,652 datasheet, HEF4011BT,652 pinout, HEF4011BT,652 application, or HEF4011BT,652 equivalent, this page delivers verified static/dynamic specifications, JEDEC-compliant ESD ratings (HBM >2000 V, CDM >1000 V), SO14 pin mapping, and real-world use cases in rail signaling logic and programmable logic array (PLA) glue logic.
Technical Context
The HEF4011BT,652 implements four independent NAND gates with fully static CMOS architecture, enabling zero static current draw at steady state and eliminating mandatory clocking. Its inputs include integrated clamp diodes, allowing safe interfacing with signals exceeding VDD when used with current-limiting resistors.
Propagation delay scales predictably with load capacitance: tpd = 12 + 0.16 × CL ns at VDD = 15 V, and output transition times (tTHL/tTLH) follow identical linear models. Logic thresholds are supply-proportional-VIH = 11.0 V and VIL = 4.0 V at 15 V-ensuring robust noise immunity across the full voltage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDD Range | 3 V to 15 V - supports direct interface with 5 V, 10 V, and 15 V logic domains without level shifters |
| Output Drive | ±4.2 mA at VDD = 15 V - sufficient to directly drive TTL loads or multiple CMOS inputs |
| Propagation Delay | 20 ns to 35 ns (typ.) at VDD = 15 V, CL = 50 pF - enables reliable timing in sub-25 MHz combinatorial logic paths |
| Operating Temp | −40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor controllers |
| ESD Rating | HBM >2000 V, CDM >1000 V - exceeds JEDEC JS-001/JS-002 Class 2/C3 for assembly-line robustness |
| Input Clamp Diodes | Integrated - permits safe connection of inputs to voltages up to VDD + 0.5 V using external series resistors |
| Static Current | ≤30 μA at VDD = 15 V, +125 °C - enables ultra-low-power standby modes in battery-backed systems |
Pinout & Package
HEF4011BT,652 is housed in a 14-lead plastic small outline package (SO14), SOT108-1 variant, with 3.9 mm body width, 1.27 mm lead pitch, and gull-wing leads compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8, 12 | 1A, 2A, 3A, 4A | First input per NAND gate - electrically identical; unused inputs must be tied to VDD, VSS, or another input |
| 2, 6, 9, 13 | 1B, 2B, 3B, 4B | Second input per NAND gate - shares same clamping and threshold behavior as A inputs |
| 3, 4, 10, 11 | 1Y, 2Y, 3Y, 4Y | Active-low NAND outputs - each capable of sourcing/sinking ≥4 mA at 15 V for fanout ≥10 |
| 7 | VSS | Ground reference (0 V) - must be low-impedance connection to minimize ground bounce in multi-gate switching |
| 14 | VDD | Positive supply - decoupling capacitor (100 nF ceramic) required within 5 mm for stable high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| Supply Voltage Flexibility | Operates across 3 V–15 V without internal regulation - eliminates need for separate LDOs in mixed-voltage systems |
| Symmetrical Output Drive | Matched pull-up/pull-down strength ensures consistent rise/fall times and reduces signal skew in critical paths |
| Wide Temperature Range | Specified from −40 °C to +125 °C - validated for use in engine control units and railway signaling hardware |
| Input Overvoltage Tolerance | Clamp diodes allow safe interface with 24 V sensors or legacy 5 V logic using simple series resistors (e.g., 10 kΩ) |
| Low Static Power | IDD ≤ 1.0 μA at 25 °C - enables always-on monitoring circuits in energy-constrained IoT edge nodes |
Applications
| Railway Signaling Logic | Industrial PLC Input Conditioning |
|---|---|
|
Use Scenario: Detecting track occupancy via dual-redundant sensor inputs before enabling switch actuation. IC Role / Device Role / Timing Role: NAND gate implements voter logic: only when both sensors agree on "occupied" does output assert. Use Value: Eliminates need for microcontroller-based voting; deterministic propagation delay (<35 ns) ensures fail-safe response within safety-critical timing windows. |
Use Scenario: Converting 24 V dry-contact field inputs into clean 5 V logic levels for PLC CPU modules. IC Role / Device Role / Timing Role: Acts as level-shifting buffer with built-in input clamping, replacing discrete resistor-diode networks. Use Value: Reduces BOM count by 4× per channel and improves EMC immunity via controlled slew rates and low input leakage (<0.1 μA). |
| Programmable Logic Array (PLA) Glue Logic | Battery-Powered Sensor Node Wake Control |
|
Use Scenario: Implementing product-term decoding in custom PLA architectures for legacy industrial controllers. IC Role / Device Role / Timing Role: Provides compact, predictable NAND-based minterm generation with fixed delay characteristics. Use Value: Enables deterministic setup/hold timing across temperature (−40 °C to +125 °C) without recalibration or compensation. |
Use Scenario: Enabling ultra-low-power wake-on-event functionality in environmental sensor nodes. IC Role / Device Role / Timing Role: NAND gate combines motion-detection interrupt and timer-expiry signals to trigger MCU wake-up. Use Value: Draws ≤1 μA quiescent current at 3 V, extending coin-cell battery life beyond 5 years in periodic-sampling applications. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4011BE | Same logic function but TI-manufactured; wider VDD range (3–18 V); higher max propagation delay (150 ns @ 5 V) | Less suitable for high-speed (>1 MHz) combinatorial paths due to slower timing; better for cost-sensitive consumer designs | Select CD4011BE only if 18 V operation is required and speed is non-critical; verify layout for higher capacitive loading. |
| 74HC00D | Higher speed (8 ns @ 5 V), lower VDD range (2–6 V), no input clamp diodes, HBM ESD rated to 2000 V | Requires external protection for >6 V interfacing; unsuitable for 12 V/15 V industrial rails without level shifting | Choose 74HC00D only for 5 V-only systems demanding sub-10 ns delays; avoid in mixed-voltage or overvoltage-prone environments. |
Compared with CD4011BE and 74HC00D, the HEF4011BT,652 uniquely balances wide supply range (3–15 V), integrated overvoltage protection, and industrial temperature rating-making it the only option qualified for direct 12 V sensor interfacing in harsh environments without external components.

FAQ
Can HEF4011BT,652 drive LED indicators directly?
No. While its outputs can source/sink up to ±4.2 mA at 15 V, sustained LED current typically exceeds safe continuous output limits and risks violating IOL/IOH absolute maximum ratings. Use an external transistor or dedicated LED driver for reliable indicator control.
What is the minimum recommended decoupling capacitance for HEF4011BT,652?
A 100 nF X7R ceramic capacitor placed within 5 mm of pins 7 (VSS) and 14 (VDD) is required per the datasheet. For systems with >10 gates switching simultaneously, add a 1 μF bulk capacitor nearby to suppress supply rail droop during transient current demand.
Is HEF4011BT,652 qualified for automotive applications?
No. Although it operates from −40 °C to +125 °C, it is not AEC-Q100 qualified and lacks automotive-specific reliability testing, failure mode analysis, or PPAP documentation. Use only in non-safety-critical industrial or commercial systems.
How should unused inputs be terminated on HEF4011BT,652?
Unused inputs must be connected to either VDD, VSS, or another used input - floating inputs cause increased supply current, erratic output states, and potential thermal overstress. Tieing to VDD is preferred for NAND gates to ensure defined HIGH logic level and minimize dynamic power.
