Product details
Overview
HEF4081BT,653 from Nexperia is a quad 2-input CMOS AND gate IC in SO14 package, operating from 3.0 V to 15.0 V supply, with ±10 mA output drive, 40 ns max propagation delay at 15 V, and rated for -40 °C to +125 °C ambient. It serves as a fundamental combinational logic building block in power management sequencing, digital interface level translation, and industrial control signal gating.
For engineers reviewing the HEF4081BT,653 datasheet, HEF4081BT,653 pinout, HEF4081BT,653 application, or HEF4081BT,653 equivalent, key selection criteria include wide VDD range compatibility, ESD-hardened inputs (HBM >2000 V), symmetrical output drive, temperature-rated performance up to +125 °C, and SO14 footprint suitability for space-constrained PCB layouts.
Technical Context
The HEF4081BT,653 implements four independent AND gates using standard CMOS silicon technology, each with clamped inputs enabling safe interfacing to voltages exceeding VDD via external current-limiting resistors. Its static operation ensures zero DC current draw in steady state, while symmetrical VOH/VOL characteristics support bidirectional logic level compatibility across mixed-voltage systems.
Propagation delay scales predictably with supply voltage and load capacitance: tPHL/tPLH range from 20–40 ns at 15 V (CL = 50 pF), down to 55–110 ns at 5 V. Dynamic power dissipation follows VDD²-dependent formulas, allowing accurate estimation under real-world switching conditions and capacitive loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 15.0 V - supports direct integration into 5 V, 10 V, and 15 V logic domains without level shifters |
| Propagation Delay (15 V) | 20 ns (min) to 40 ns (max) at CL = 50 pF - enables reliable timing in sub-25 MHz synchronous logic paths |
| Output Drive Current | ±4.2 mA (IOH/IOL at VDD = 15 V) - sufficient to drive 10+ 74HC inputs or small capacitive loads directly |
| Input Clamp Protection | VI < −0.5 V or > VDD + 0.5 V - allows safe overvoltage input handling with series resistors |
| ESD Rating (HBM) | Class 2 (>2000 V) per JS-001 - reduces need for external ESD protection in industrial I/O interfaces |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood automotive auxiliary modules and industrial motor controllers |
| Static Supply Current | ≤30.0 μA at VDD = 15 V, +125 °C - enables ultra-low-power standby modes in battery-backed systems |
Pinout & Package
HEF4081BT,653 is housed in a plastic small outline package (SO14), SOT108-1 variant, with 14 leads, 3.9 mm body width, and 1.27 mm lead pitch. The package meets JEDEC MS-012 and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8, 12 | 1A, 2A, 3A, 4A | First input of each AND gate - accepts TTL- or CMOS-compatible logic levels |
| 2, 6, 9, 13 | 1B, 2B, 3B, 4B | Second input of each AND gate - independently configurable per gate |
| 3, 4, 10, 11 | 1Y, 2Y, 3Y, 4Y | AND output (nA ∧ nB) - rail-to-rail CMOS output swing referenced to VDD/VSS |
| 7 | VSS | Ground reference (0 V) - must be low-impedance connection for noise immunity |
| 14 | VDD | Positive supply rail - decoupling capacitor (100 nF) recommended adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| Fully static CMOS operation | Zero quiescent current in stable logic states - eliminates static power penalty in always-on control logic |
| Wide VDD range (3–15 V) | Single part replaces multiple voltage-specific logic families - simplifies BOM and design reuse |
| Input clamp diodes | Enables robust interfacing to external signals up to VDD + 0.5 V without damage - reduces external protection components |
| High noise immunity | Typical VIH/VIL margins ≥40% of VDD - maintains logic integrity in electrically noisy industrial environments |
| JEDEC JESD13-B compliance | Guarantees interoperability with legacy 4000-series logic designs and test infrastructure |
Applications
| Industrial PLC Input Conditioning | Power Sequencing Control |
|---|---|
|
Use Scenario: Isolating and synchronizing discrete sensor inputs (e.g., limit switches, proximity sensors) before feeding into microcontroller GPIOs. IC Role / Device Role / Timing Role: Logic-level gating and noise filtering for asynchronous field signals prior to MCU sampling. Use Value: Clamp diodes and high noise immunity prevent false triggering; wide VDD supports direct 12 V sensor interface without level-shifting. |
Use Scenario: Enabling downstream DC-DC converters only after upstream rails reach regulation and interlock conditions are met. IC Role / Device Role / Timing Role: Combinatorial enable logic combining reset, voltage OK, and thermal fault signals. Use Value: Guaranteed propagation delay ≤40 ns ensures deterministic power-up sequence timing; 15 V rating matches industrial supply rails. |
| Digital Interface Level Translation | Legacy System Bus Gating |
|
Use Scenario: Interfacing 3.3 V FPGA I/O to 5 V or 12 V peripheral buses where direction control is fixed. IC Role / Device Role / Timing Role: Unidirectional voltage-domain bridging via AND-enabled signal passthrough. Use Value: Symmetrical VOH/VOL and rail-to-rail outputs ensure clean logic thresholds across mixed-supply domains. |
Use Scenario: Selectively enabling address/data lines on aging 4000-series or 74LS-based backplanes during firmware updates. IC Role / Device Role / Timing Role: Hardware-enforced bus isolation to prevent contention during hot-swap or reconfiguration. Use Value: −40 °C to +125 °C rating ensures reliability in uncontrolled cabinet environments; SO14 footprint fits legacy board layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input AND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4081BE | Same logic function but PDIP-14 package; wider propagation delay (120 ns @ 5 V); no HBM ESD rating specified | Limited to through-hole prototyping or legacy repair; unsuitable for surface-mount production or harsh ESD environments | Select when DIP socketing or legacy replacement is required; avoid for new SMT designs or industrial ESD zones |
| 74HC08PW,118 | Higher speed (19 ns @ 4.5 V), lower VDD range (2–6 V), no input clamps, lower ESD tolerance (HBM ~2 kV) | Better for high-speed 3.3 V/5 V systems; cannot interface safely to >VDD signals without external protection | Prefer for dense, high-frequency digital logic; use HEF4081BT,653 instead when overvoltage resilience or 12/15 V operation is needed |
Compared with CD4081BE and 74HC08PW,118, the HEF4081BT,653 uniquely balances wide supply flexibility (3–15 V), input overvoltage tolerance, and industrial temperature capability - making it the only choice for mixed-voltage, high-reliability embedded control where signal integrity and ruggedness outweigh raw speed.

FAQ
Can HEF4081BT,653 operate reliably at 15 V with full output drive at +125 °C?
Yes. Per Table 6 and Table 7 of the datasheet, VOH remains ≥14.95 V and IOL reaches ≥2.4 mA at VDD = 15 V and Tamb = +125 °C, confirming full rail-to-rail output swing and specified drive strength across the entire industrial temperature range.
Does HEF4081BT,653 require external pull-up or pull-down resistors on unused inputs?
No. Unused inputs may be tied directly to VDD or VSS. The datasheet explicitly permits this due to CMOS input structure and internal protection; floating inputs are prohibited to avoid increased supply current and potential oscillation.
What is the maximum capacitive load the HEF4081BT,653 can drive while maintaining timing specifications?
The datasheet specifies dynamic characteristics up to CL = 50 pF (Table 10). Propagation delay increases linearly with load: at 15 V, tPHL = 12 ns + (0.16 ns/pF) × CL. For timing-critical paths, keep CL ≤50 pF; higher loads increase delay and transition time but do not impair functionality.
Is HEF4081BT,653 pin-compatible with older HEF4081BP (SOT27-1) devices?
No. HEF4081BP used the obsolete SOT27-1 (14-lead DIP-style SMD) package with different pin spacing and layout. HEF4081BT,653 uses SOT108-1 (SO14), which has distinct mechanical dimensions and land pattern requirements - PCB redesign is necessary for replacement.
