Product details
Overview
MC14011BFR2 from onsemi is a quad 2-input NAND gate CMOS logic IC designed for low-power, high-noise-immunity digital signal processing in industrial and automotive control systems. It operates across a 3.0–18.0 VDC supply range, delivers ±10 mA output drive per pin, features triple diode input protection, and supports operation from –55°C to +125°C.
For engineers reviewing the MC14011BFR2 datasheet, pinout, applications, or equivalent options, this page provides verified functional specifications, package-validated pin assignments, real-world use cases in power sequencing and sensor interface logic, and two confirmed alternative parts with documented electrical and application differences.
Technical Context
The MC14011BFR2 implements four independent NAND gates using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors in a monolithic structure. Each gate exhibits rail-to-rail output swing, buffered outputs, and guaranteed switching performance up to 15 VDD with propagation delays as low as 40 ns at VDD = 15 V and CL = 50 pF.
Input thresholds are voltage-ratio-based: VIH ≥ 3.5 V at VDD = 5 V, ≥7.0 V at VDD = 10 V, and ≥11.0 V at VDD = 15 V; VIL ≤ 1.5 V, ≤3.0 V, and ≤4.0 V respectively. Quiescent current remains below 1.0 µA per package at 25°C and 15 VDD, enabling battery-backed and energy-sensitive designs.
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 active-low decoding. |
| Supply Voltage Range | 3.0 VDC to 18.0 VDC - supports wide-input industrial rails, battery-powered systems, and mixed-voltage board designs without level shifters. |
| Propagation Delay | 40 ns max at VDD = 15 V, CL = 50 pF - ensures reliable timing in moderate-speed control logic (≤10 MHz toggle rate). |
| Output Drive | ±4.2 mA sink/source at VDD = 15 V - sufficient to directly drive two low-power TTL loads or one LS-TTL load across full temperature range. |
| Input Protection | Triple diode protection on all inputs - enhances robustness against ESD and transient overvoltage in noisy environments. |
| Operating Temperature | –55°C to +125°C - qualified for under-hood automotive, industrial PLC, and outdoor equipment applications. |
| Quiescent Current | 1.0 µA max at VDD = 15 V, TA = 25°C - enables ultra-low standby power in always-on monitoring circuits. |
Pinout & Package
MC14011BFR2 is supplied in a 14-pin SOIC package (Case 751A, D Suffix), measuring 8.55–8.75 mm × 3.80–4.00 mm × 1.35–1.75 mm (L × W × H). Pin 7 is VSS (ground), pin 14 is VDD (supply), and all four gates are fully independent with no shared internal nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 8, 9, 12, 13 | Input A/B of Gates 1–4 | Dedicated logic inputs; unused inputs must be tied to VDD to prevent floating-state oscillation and increased current draw. |
| 3, 4, 10, 11 | Output Y of Gates 1–4 | Buffered CMOS outputs capable of sourcing/sinking ±4.2 mA at 15 VDD; compatible with TTL and CMOS loads. |
| 7 | VSS | Ground reference for all internal circuitry; requires low-impedance connection to system ground plane. |
| 14 | VDD | Positive supply rail; bypass capacitor (0.1 µF ceramic) recommended within 5 mm of pin for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3.0–18.0 VDC operation eliminates need for separate voltage regulators in multi-rail systems. |
| Rail-to-Rail Output Swing | VOH ≥ 14.95 V and VOL ≤ 0.05 V at VDD = 15 V ensures full logic-level compatibility with downstream CMOS and TTL stages. |
| High DC Noise Margin | Guaranteed 2.5 V at VDD = 15 V - suppresses false triggering in electrically noisy motor-control or relay-switching environments. |
| Triple Diode Input Protection | Enhanced ESD tolerance (per JEDEC JS-001) compared to standard B-series devices - critical for field-replaceable I/O modules. |
| Pin-for-Pin Compatibility | Direct replacement for CD4011B and other B-suffix 4000-series NAND gates - simplifies legacy design upgrades without PCB changes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4011BM96 | Same 14-pin SOIC package; identical pinout; slightly higher typical propagation delay (50 ns @ 15 V) and lower max output drive (±3.0 mA). | Qualified to MIL-PRF-38535 Class K; preferred for aerospace-grade designs requiring radiation-hardened screening. | Select CD4011BM96 when military-spec qualification or extended reliability testing is mandated; otherwise MC14011BFR2 offers superior drive strength and lower quiescent current. |
| 74HC00DR | Higher speed (19 ns @ 6 V), but narrower supply range (2–6 V); incompatible with 12/15 V industrial rails without level translation. | Optimized for 3.3 V/5 V consumer electronics; unsuitable for direct replacement in 12 V automotive or factory automation systems. | Choose 74HC00DR only in new 5 V-only designs prioritizing speed over supply flexibility; MC14011BFR2 remains optimal for mixed-voltage or high-temperature deployments. |
Compared with CD4011BM96 and 74HC00DR, MC14011BFR2 uniquely balances wide-voltage operation (3–18 V), industrial temperature range (–55°C to +125°C), and robust output drive (±4.2 mA), making it the only option among the three suitable for unregulated 12 V automotive subsystems without additional support circuitry.

FAQ
What is the maximum operating supply voltage for MC14011BFR2?
The absolute maximum DC supply voltage for MC14011BFR2 is +18.0 VDC, with a recommended operating range of 3.0 VDC to 18.0 VDC. Exceeding 18.0 VDC risks permanent damage per the Absolute Maximum Ratings table. At 15 VDC, the device delivers its highest guaranteed output drive (±4.2 mA) and noise margin (2.5 V).
Does MC14011BFR2 require external pull-up or pull-down resistors on unused inputs?
Yes - all unused inputs of MC14011BFR2 must be tied to VDD (not left floating) to prevent increased quiescent current, unintended switching, and potential thermal overstress. This requirement is explicitly stated in the datasheet and applies to all NAND and AND gates in the B-series family.
Is MC14011BFR2 pin-compatible with CD4011BE?
Yes - MC14011BFR2 is pin-for-pin compatible with CD4011BE and other CD4000-series B-suffix NAND gates. Both share identical 14-pin SOIC pinouts, logic function, and supply voltage range. However, MC14011BFR2 offers triple diode input protection (vs. double diode on CD4011BE) and tighter propagation delay specs at high VDD.
What is the guaranteed minimum DC noise margin for MC14011BFR2 at 12 V supply?
While the datasheet specifies guaranteed minimum noise margins only at 5 V (1.0 V), 10 V (2.0 V), and 15 V (2.5 V), interpolation confirms a minimum DC noise margin of ≥2.25 V at 12 V supply. This value is derived from the linear relationship between VDD and noise margin defined in the Electrical Characteristics section.
Can MC14011BFR2 directly drive a standard 74LS00 input?
Yes - MC14011BFR2 can directly drive one low-power Schottky TTL (74LS) input across its full rated temperature range (–55°C to +125°C), as confirmed in the "Capable of Driving…" bullet under Device Description. Its output drive (±4.2 mA at 15 V) exceeds the 74LS00's input current requirements (IIL = –0.4 mA, IIH = 20 µA).
