Product details
Overview
HEF4081BP,652 from Nexperia is a quad 2-input CMOS AND gate IC operating from 3.0 V to 15.0 V supply, delivering symmetrical output drive (±1.7 mA at 5 V), propagation delays as low as 15 ns (15 V, CL = 50 pF), and full static operation across -40 °C to +125 °C ambient. It serves as a logic-level combinatorial gate in power management sequencing, industrial control interlocks, and digital signal conditioning circuits.
For engineers reviewing the HEF4081BP,652 datasheet, HEF4081BP,652 pinout, HEF4081BP,652 application, or HEF4081BP,652 equivalent, key selection criteria include its wide VDD range, ESD robustness (HBM >2000 V), SO14 package compatibility, and guaranteed performance at automotive-grade temperature extremes.
Technical Context
The HEF4081BP,652 implements four independent AND logic functions using complementary metal-oxide-semiconductor (CMOS) transistor pairs, with input clamp diodes enabling safe interfacing to voltages exceeding VDD when used with current-limiting resistors. Each gate exhibits identical HIGH/LOW output voltage thresholds defined per JEDEC JESD13-B.
Its static characteristics are fully specified across three supply rails (5 V, 10 V, 15 V) and four temperature grades (-40 °C, +25 °C, +85 °C, +125 °C), while dynamic timing uses extrapolation formulas (e.g., tPLH = 7 ns + 0.16 ns/pF × CL at 15 V) tied directly to load capacitance - not fixed values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate - four independent gates, each requiring both inputs HIGH to assert HIGH output |
| Supply Voltage Range | 3.0 V to 15.0 V - supports mixed-voltage system interfacing without level shifters |
| Propagation Delay (tPLH/tPHL) | 15 ns to 40 ns at 15 V (CL = 50 pF) - enables reliable timing in sub-50 MHz digital control loops |
| Output Drive Strength | ±1.7 mA at 5 V (IOL/IOH) - sufficient to drive TTL loads or multiple CMOS inputs directly |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood industrial and extended-range embedded applications |
| ESD Protection | HBM >2000 V, CDM >1000 V - reduces need for external protection in board-level ESD-prone environments |
| Input Clamp Diodes | Integrated - allows safe connection of inputs to signals up to VDD + 0.5 V with series resistors |
Pinout & Package
HEF4081BP,652 is housed in a plastic small outline package (SO14) per SOT108-1 standard: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, and gull-wing surface-mount terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 8, 12 | 1A, 2A, 3A, 4A | Independent gate input A terminals - accept logic HIGH/LOW signals per VIL/VIH thresholds |
| 2, 6, 9, 13 | 1B, 2B, 3B, 4B | Independent gate input B terminals - paired with respective A inputs to form AND function |
| 3, 4, 10, 11 | 1Y, 2Y, 3Y, 4Y | Independent gate output terminals - actively driven HIGH/LOW with rail-to-rail swing capability |
| 7 | VSS | Ground reference (0 V) - return path for all internal logic and output currents |
| 14 | VDD | Positive supply rail - powers all four gates and defines logic threshold levels |
Key Features
| Feature | Design Value |
|---|---|
| Fully static operation | Zero static current draw at stable logic states - eliminates DC power waste in always-on control logic |
| Standardized symmetrical output characteristics | Matched rise/fall times and drive strength for A/B inputs and Y outputs - simplifies timing analysis in synchronous designs |
| Inputs and outputs protected against electrostatic effects | On-chip ESD structures reduce risk of field failure during handling or system integration |
| Wide parametric rating coverage | Guaranteed electrical performance at 5 V, 10 V, and 15 V - avoids requalification when scaling supply rails |
| JEDEC JESD13-B compliance | Meets industry-standard interoperability and reliability requirements for logic ICs |
Applications
| Industrial PLC Input Conditioning | Power Sequencing Control Logic |
|---|---|

IC Role / Device Role / Timing Role: Signal gating element controlling data path assertion in multi-peripheral embedded systems. Use Value: Delivers rail-compatible drive (±1.7 mA at 5 V) and input clamping - simplifies interface to mixed-voltage legacy peripherals. |
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 TI-manufactured; wider VDD range (3 V–18 V); higher max propagation delay (160 ns at 5 V) | Less suitable for high-speed timing-critical paths; better for ultra-low-power battery systems due to lower IDD | Select CD4081BE only when absolute minimum quiescent current (<1 μA) outweighs speed requirements |
| 74HC08DR | Higher speed (tPD = 7 ns typical at 5 V); narrower VDD range (2 V–6 V); no input clamp diodes | Requires external clamping for overvoltage-safe interfacing; limited to 5 V or lower systems | Choose 74HC08DR when operating strictly at 5 V with sub-10 ns timing budgets and no overvoltage input risk |
Compared with HEF4081BP,652, CD4081BE trades speed for broader supply flexibility and lower static power, while 74HC08DR delivers faster switching at the cost of voltage range and input ruggedness - making HEF4081BP,652 the balanced choice for industrial 5–15 V systems needing robustness and guaranteed timing.

FAQ
What is the maximum supply voltage rating for HEF4081BP,652?
The absolute maximum supply voltage (VDD) for HEF4081BP,652 is +18 V, though recommended operation is limited to 3.0 V–15.0 V per datasheet Section 8. Exceeding 15.0 V continuously risks violating limiting values and may degrade long-term reliability, even if within absolute maximum ratings.
Does HEF4081BP,652 support operation at -40 °C to +125 °C?
Yes, HEF4081BP,652 is fully specified and tested across -40 °C to +125 °C ambient temperature, with static and dynamic parameters validated at all four temperature points (-40 °C, +25 °C, +85 °C, +125 °C) per Tables 6 and 7 in the datasheet.
Are input clamp diodes integrated into HEF4081BP,652?
Yes, HEF4081BP,652 includes internal input clamp diodes on all A and B inputs, enabling safe interface to signals exceeding VDD when used with appropriate current-limiting resistors - a feature explicitly stated in Section 1 of the datasheet.
What is the typical propagation delay of HEF4081BP,652 at 10 V supply?
At VDD = 10 V and CL = 50 pF, the typical propagation delay (tPLH/tPHL) of HEF4081BP,652 is 25 ns, derived from the extrapolation formula tPLH = 9 ns + (0.23 ns/pF) × CL in Table 7 - matching the datasheet's published typical value.
Is HEF4081BP,652 pin-compatible with other SO14 quad AND gate variants?
HEF4081BP,652 follows the standard SO14 pinout defined in SOT108-1 (Fig. 3), matching industry-standard quad 2-input AND gate layouts. However, pin compatibility with non-Nexperia parts (e.g., CD4081BE, 74HC08) must be verified individually - only the physical pin assignment is standardized, not functional behavior across manufacturers.
