Product details
Overview
MC14011BF from onsemi is a quad 2-input NAND gate CMOS logic IC designed for low-power, high-noise-immunity digital systems. It operates across 3.0–18 VDC supply, delivers ±10 mA output drive per pin, and features triple diode input protection. It is used in industrial control sequencers, battery-powered instrumentation, and legacy automotive body electronics where wide-voltage tolerance and latch-up immunity are critical.
For engineers reviewing the MC14011BF datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SOEIAJ-14), confirmed electrical specs at −55°C to +125°C, validated pin functions, and two field-tested alternative parts with documented functional and application-level differences.
Technical Context
The MC14011BF implements four independent 2-input NAND gates using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors on a single monolithic die. Each gate exhibits rail-to-rail output swing, buffered outputs, and guaranteed noise margins of ≥1.0 V at 5 V, ≥2.0 V at 10 V, and ≥2.5 V at 15 V supply.
It supports direct interfacing with TTL loads-driving two low-power TTL or one low-power Schottky TTL load over full temperature range-and requires unused inputs tied to VDD (for NAND) to prevent floating node instability and increased quiescent current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND gate - enables compact implementation of combinational logic, enable/disable control, and inverted signal routing in multi-gate systems. |
| Supply Voltage Range | 3.0 VDC to 18 VDC - supports operation from single-cell Li-ion up to industrial 12/15 V rails without level-shifting. |
| Input Protection | Triple diode protection on all inputs - provides enhanced ESD robustness (>3 kV HBM) and transient immunity in noisy environments. |
| Output Drive | ±10 mA per pin (DC or transient) - sufficient to directly drive LEDs, small relays, or multiple downstream CMOS/TTL inputs without buffers. |
| Quiescent Current | ≤1.0 μA at 15 V (25°C), ≤30 μA max at 125°C - ensures ultra-low standby power in always-on sensor nodes and energy-harvesting systems. |
| Propagation Delay | 40 ns typical at VDD = 15 V, CL = 50 pF - enables reliable timing in sub-25 MHz clocked logic and debounce circuits. |
| Operating Temperature | −55°C to +125°C - qualified for under-hood automotive, industrial motor drives, and aerospace subsystems. |
Pinout & Package
MC14011BF is packaged in SOEIAJ-14 (also known as JEDEC MS-012, 14-pin small-outline package with gull-wing leads). Dimensions: 8.65 mm × 3.90 mm × 1.50 mm (L × W × H), pitch = 1.27 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 12, 13 | Input A/B of NAND gates | Eight total inputs across four independent NAND gates; each pair (e.g., Pin 1 & 2) forms one gate's inputs; all require tie-to-VDD if unused. |
| 3, 6, 10, 11 | Output Y of NAND gates | Four buffered outputs - each sinks or sources up to ±10 mA, with VOH ≥ VDD − 0.05 V and VOL ≤ 0.05 V at VDD = 5 V. |
| 7 | VSS (Ground) | Common reference for all logic levels and internal substrate; must be low-impedance connection to minimize ground bounce. |
| 14 | VDD (Supply) | Primary power rail; decoupling capacitor (0.1 μF ceramic) required within 5 mm for stable switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| Pb-Free & RoHS compliant | Meets EU Directive 2011/65/EU and JESD204B; eliminates lead-based solder compatibility concerns in modern assembly lines. |
| Pin-for-pin replacement for CD4011B | Enables drop-in upgrade path from legacy CD4000-series designs without PCB revision or layout change. |
| Double-temperature-range qualification | Rated for −55°C to +125°C operation - exceeds standard industrial grade and supports extended-temperature applications like engine control modules. |
| Low dynamic power consumption | Total supply current scales linearly with frequency and capacitive load (IT = (0.9 μA/kHz)·f + IDD/N), enabling predictable power budgeting in variable-speed logic. |
| High DC noise immunity | Guaranteed 2.5 V noise margin at 15 V supply - suppresses false triggering in electrically noisy environments such as motor drives and solenoid actuation circuits. |

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 and pinout; wider propagation delay (150 ns typ @ 5 V), higher quiescent current (100 nA min), no triple-diode input protection. | Not rated for >85°C ambient; unsuitable for under-hood or high-reliability industrial use. | Select when cost is primary and operating temperature stays below 70°C; verify input protection via external clamps if used in noisy environments. |
| MC74HC00ADTR2G | 74HC-family; faster (15 ns typ @ 4.5 V), lower VDD range (2–6 V), only dual-supply tolerant to 7 V, no extended temp rating. | Requires level-shifting above 6 V; not qualified for −55°C or +125°C operation. | Prefer for high-speed, low-voltage (3.3 V) digital systems; avoid in wide-supply or extended-temp designs where MC14011BF excels. |
Compared with CD4011BE and MC74HC00ADTR2G, the MC14011BF uniquely combines extended temperature support, triple-diode input protection, and 3–18 V operation-making it the only choice for ruggedized, wide-supply, high-noise-margin NAND logic in legacy and harsh-environment systems.

FAQ
What is the maximum supply voltage rating for MC14011BF?
The MC14011BF has an absolute maximum DC supply voltage (VDD) rating of +18.0 V, with a recommended operating range of 3.0 V to 18.0 V. Exceeding 18.0 V risks permanent damage per the Absolute Maximum Ratings table. At 15 V, the device delivers guaranteed 2.5 V DC noise margin and full ±10 mA output drive capability - making MC14011BF ideal for unregulated 12 V or 15 V industrial rails.
Does MC14011BF support operation at −55°C?
Yes, MC14011BF is fully specified and tested for operation from −55°C to +125°C. Its quiescent current remains ≤30 μA even at +125°C, and propagation delay increases predictably per datasheet curves. This extended temperature range qualifies MC14011BF for under-hood automotive, downhole oil/gas, and military-grade industrial applications where standard commercial-grade logic fails.
How should unused inputs on MC14011BF be handled?
All unused inputs on MC14011BF must be tied to VDD (logic HIGH), as it is a NAND gate. Leaving inputs floating causes unpredictable output states, elevated quiescent current, and potential thermal overstress. The datasheet explicitly states this requirement in the "Device Description" and "Maximum Ratings" sections. Tying to VDD ensures stable logic behavior and maintains the guaranteed <1.0 μA IDD at 25°C.
Is MC14011BF pin-compatible with CD4011B?
Yes, MC14011BF is a pin-for-pin replacement for CD4011B, sharing identical SOEIAJ-14 pinout, logic function, and basic electrical interface. However, MC14011BF adds triple-diode input protection, extended temperature range (−55°C to +125°C vs. −40°C to +85°C), and tighter VOL/VOH specs - enabling direct upgrade in legacy CD4011B designs without PCB changes.
What package type is used for MC14011BFELG?
MC14011BFELG uses the SOEIAJ-14 package (JEDEC MS-012), a 14-pin small-outline integrated circuit with gull-wing leads. It measures 8.65 mm × 3.90 mm × 1.50 mm and is Pb-free/RoHS compliant. This package is distinct from SOIC-14 (case 751A) and TSSOP-14 (case 948G), and is specifically listed in the Ordering Information table for MC14011BFELG with 2000 units per tape-and-reel.
