Product details
Overview
MC14081BFEL from onsemi is a quad 2-input CMOS AND gate in SOEIAJ-14 (JEDEC MS-012) package, operating from 3.0 V to 18.0 V supply, delivering ±10 mA output drive per pin, with triple diode input protection and buffered outputs. It serves as a low-power logic building block in industrial control sequencers, battery-powered instrumentation, and noise-immune sensor interface circuits.
For engineers reviewing the MC14081BFEL datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated pin assignments, confirmed supply range and drive capability, and two rigorously cross-checked alternative parts for design continuity.
Technical Context
The MC14081BFEL implements four independent 2-input AND functions using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors on a single monolithic die. Its architecture enables rail-to-rail output swing and high DC noise immunity-guaranteed minimum 2.5 V at 15 V supply-with no internal pull-ups or open-drain configuration.
All inputs feature triple diode protection (unlike standard double-diode B-series gates), and all outputs are buffered to ensure consistent drive strength across temperature (−55 °C to +125 °C) and supply voltage (3–18 V). Unused inputs must be tied to VDD or VSS; unused outputs remain open.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input AND gate - four independent Boolean AND operations per package |
| Supply Voltage Range | 3.0 V to 18.0 V DC - supports wide-range industrial and legacy 5/12/15 V systems without level shifters |
| Output Drive | ±10 mA per pin - sufficient to directly drive two low-power TTL loads or one LS-TTL load over full temperature range |
| Input Protection | Triple diode protection - enhanced ESD robustness vs. standard B-series dual-diode inputs |
| DC Noise Margin | 2.5 V min at VDD = 15 V - ensures reliable operation in electrically noisy environments (e.g., motor controls) |
| Quiescent Current | ≤30 µA per package at 15 V - enables ultra-low standby power in battery-backed systems |
| Propagation Delay | 40 ns max at VDD = 15 V, CL = 50 pF - deterministic timing for synchronous logic sequencing |
Pinout & Package
MC14081BFEL is housed in a 14-pin SOEIAJ (JEDEC MS-012) surface-mount package - 8.75 mm × 4.00 mm footprint, 1.75 mm height, 1.27 mm pitch - compatible with standard SOIC-14 reflow profiles and PCB footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 8, 9, 12, 13 | Input A/B of Gates A–D | Eight dedicated logic inputs - each pair (e.g., Pin 1 & 2) feeds one AND gate; all require explicit VDD/VSS tie-off when unused |
| 3, 4, 10, 11 | Output A–D | Four buffered CMOS outputs - rail-to-rail swing, capable of sourcing/sinking ±10 mA, no external pull-up needed |
| 7 | VSS | Ground reference - mandatory connection point for all internal logic and protection circuitry |
| 14 | VDD | Positive supply - powers all four gates and input protection networks; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3.0–18.0 V operation eliminates need for separate voltage regulators in mixed-supply systems |
| Triple Diode Input Protection | Enhanced ESD tolerance (>3 kV HBM) versus standard B-series, critical for field-deployed industrial interfaces |
| Buffered Outputs | Consistent rise/fall times and drive strength across temperature and supply, enabling predictable timing margins |
| Pb-Free & RoHS Compliant | Meets global environmental compliance requirements without performance trade-offs or derating |
| Automotive-Qualified Variant Available | NLV14081B prefix offers AEC-Q100 qualification and PPAP support for automotive body electronics |

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 |
|---|---|---|---|
| CD4081BM96 | Same logic function and pinout; wider −55 °C to +125 °C rating but only 3–15 V supply range and no triple diode protection | Preferred where legacy CD4000-series compatibility is mandatory and ESD stress is minimal | Select CD4081BM96 only if system operates ≤15 V and resides in controlled lab environments |
| 74HCT08DR | TTL-compatible input thresholds (2.0 V VIH), 4.5–5.5 V supply only, faster propagation (19 ns typ), but no high-voltage operation | Suitable for 5 V digital systems requiring tighter timing budgets and interfacing with legacy TTL outputs | Choose 74HCT08DR when interfacing with 5 V microcontrollers and speed >40 ns is required |
Compared with CD4081BM96 and 74HCT08DR, MC14081BFEL uniquely supports 18 V operation, triple-diode ESD hardening, and full industrial temperature range at 3–18 V-making it the sole option for 12/15 V industrial sensors and harsh-environment control logic.

FAQ
What logic function does the MC14081BFEL implement?
The MC14081BFEL implements four independent 2-input AND gates in a single SOEIAJ-14 package. Each gate performs the Boolean AND operation: output is HIGH only when both inputs are HIGH. This is confirmed by the device description, logic diagram, and truth table in the official onsemi datasheet Rev. 13.
What is the maximum supply voltage rating for MC14081BFEL?
The MC14081BFEL has a maximum DC supply voltage (VDD) rating of +18.0 V, with absolute maximum ratings specifying −0.5 V to +18.0 V referenced to VSS. Operation beyond 18.0 V risks permanent damage, as stated in the Maximum Ratings table on page 1 of the datasheet.
Does MC14081BFEL have built-in input protection diodes?
Yes, MC14081BFEL features triple diode protection on all inputs-a distinguishing feature versus most other B-series gates which use double diode protection. This is explicitly noted in the Features section and confirmed in the device comparison table on page 1 of the datasheet.
What package type is used for MC14081BFEL?
MC14081BFEL uses the SOEIAJ-14 package (also known as JEDEC MS-012), a 14-pin small-outline integrated circuit variant with gull-wing leads. This is verified in the Ordering Information table on page 8 of the datasheet, where "MC14081BFELG" is listed with "SOEIAJ-14 (Pb-Free)".
Is MC14081BFEL pin-compatible with CD4081B devices?
Yes, MC14081BFEL is pin-for-pin compatible with corresponding CD4000 series B-suffix devices, including CD4081B. The datasheet states "Pin-for-Pin Replacements for Corresponding CD4000 Series B Suffix Devices" in the Features section, and the pin assignments match identically across both families.
