Product details
Overview
MC14011BFL1 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 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 MC14011BFL1 datasheet, pinout, applications, or equivalent options, this page provides verified functional specifications, package-confirmed pin assignments, real-world use cases in power sequencing and sensor interface logic, and validated alternative parts with documented electrical and application differences.
Technical Context
The MC14011BFL1 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 DC noise margins of 1.0 V (at 5 V), 2.0 V (at 10 V), and 2.5 V (at 15 V).
It supports dynamic loading up to 50 pF per gate with propagation delays of 40 ns (typical at VDD = 15 V, CL = 50 pF), rise/fall times of 40 ns (typical), and quiescent current as low as 0.5 µA per package at 10 V - enabling direct interfacing with TTL loads without level-shifting.
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 signal inversion. |
| Supply Voltage Range | 3.0 VDC to 18 VDC - allows single-supply operation across battery-powered, 5 V, 12 V, and industrial 15 V systems without regulation. |
| Output Drive Capability | ±10 mA per pin - sufficient to directly drive two low-power TTL loads or one low-power Schottky TTL load over full temperature range. |
| Input Protection | Triple diode protection - enhances ESD robustness on all inputs, exceeding standard double-diode protection found in most B-series gates. |
| Operating Temperature | –55°C to +125°C - qualified for under-hood automotive, industrial motor control, and outdoor embedded applications. |
| Propagation Delay | 40 ns typical at VDD = 15 V, CL = 50 pF - ensures reliable timing in moderate-speed digital control loops and state-machine clocking. |
| Quiescent Current | 0.5 µA typical at VDD = 10 V - enables ultra-low standby power in battery-backed or energy-harvesting systems. |
Pinout & Package
MC14011BFL1 is packaged in a 14-pin plastic EIAJ SOIC (F suffix, Case 965), with 0.390-inch body width, 0.050-inch lead pitch, and gull-wing leads. The package is RoHS-compliant and rated for reflow soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 12, 13 | NAND Input A/B (per gate) | Dedicated dual-input terminals for each of four independent NAND gates; unused inputs must be tied to VDD to prevent floating-state oscillation. |
| 3, 6, 10, 11 | NAND Output Y (per gate) | Buffered CMOS outputs capable of rail-to-rail swing and ±10 mA sourcing/sinking - suitable for driving downstream logic or small LEDs. |
| 7 | VSS | Ground reference for all internal circuitry; must be connected to system common ground with low-impedance path to minimize noise coupling. |
| 14 | VDD | Primary power supply input; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stable high-speed switching performance. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3.0–18 VDC operation eliminates need for voltage regulators in multi-rail systems and simplifies design for legacy 12 V or battery-backed circuits. |
| Triple Diode Input Protection | Enhanced ESD immunity on all inputs - critical for reliability in factory automation I/O modules exposed to frequent operator contact or cable hot-plug events. |
| Pin-for-Pin Compatibility | Direct replacement for CD4011B and other B-suffix 4000-series NAND gates - enables drop-in upgrade of legacy designs without PCB revision. |
| High Noise Immunity | Guaranteed 2.5 V DC noise margin at 15 V supply - ensures robust operation in electrically noisy environments such as motor drives and solenoid controllers. |
| Low Quiescent Power | Sub-microamp IDD at 25°C - extends battery life in portable instrumentation and remote sensor nodes where logic remains active during sleep modes. |
Applications
| Industrial Power Sequencing | Automotive Sensor Interface Logic |
|---|---|
Use Scenario: Controlling startup order of multiple DC-DC converters in programmable logic controllers. IC Role / Device Role / Timing Role: Quad NAND gate implements AND-NOT logic to generate delayed enable signals based on voltage monitor outputs.

Use Scenario: Enabling wake-up logic in solar-powered environmental sensors that activate only upon threshold-crossing events. IC Role / Device Role / Timing Role: Configured as an edge-triggered latch to detect rising/falling transitions on comparator outputs and assert interrupt to ultra-low-power MCU. Use Value: Sub-1 µA quiescent current minimizes parasitic drain; rail-to-rail output swing ensures clean logic-level signaling to MCU GPIO even at 3.3 V supply. |
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, but rated only to +85°C ambient and lacks triple diode input protection. | Not qualified for under-hood automotive or extended-temperature industrial use; lower noise margin (1.5 V at 10 V). | Select when cost is primary constraint and operating temperature stays below 85°C; verify ESD robustness in final system. |
| 74HC00DR | Higher speed (8 ns typical tPD at 5 V), but narrow 2–6 V supply range and no extended temperature rating. | Suitable only for commercial-grade 5 V systems; incompatible with 12 V or battery-voltage rails without level translation. | Choose for high-speed digital logic in consumer electronics; avoid in mixed-voltage or harsh-environment designs. |
Compared with CD4011BM96 and 74HC00DR, MC14011BFL1 uniquely combines extended temperature operation (–55°C to +125°C), triple-diode ESD protection, and 3–18 VDC flexibility - making it the only option qualified for automotive powertrain and industrial motor control logic without external support components.

FAQ
What is the maximum supply voltage rating for MC14011BFL1?
The absolute maximum DC supply voltage for MC14011BFL1 is +18.0 VDC referenced to VSS. Operation above this voltage risks permanent device damage. The recommended operating range is 3.0 VDC to 18.0 VDC, with guaranteed performance across the full –55°C to +125°C temperature range. Always include a 0.1 µF ceramic decoupling capacitor between VDD (pin 14) and VSS (pin 7).
Does MC14011BFL1 support direct connection to TTL logic inputs?
Yes, MC14011BFL1 is specified to drive two low-power TTL loads or one low-power Schottky TTL load over its full rated temperature range. Its output voltage levels (VOH ≥ 4.95 V at VDD = 5 V, VOL ≤ 0.05 V) and drive strength (±10 mA per pin) meet TTL input thresholds and fan-out requirements without level-shifting circuitry.
How should unused inputs on MC14011BFL1 be handled?
All unused inputs on MC14011BFL1 must be tied to VDD (pin 14) - not left floating - because it is a NAND gate. Floating CMOS inputs cause increased power consumption, potential oscillation, and susceptibility to noise-induced false triggering. This requirement is explicitly stated in the datasheet and applies to all four gates independently.
What is the meaning of the "FL1" suffix in MC14011BFL1?
The "FL1" suffix identifies the specific packaging and marking variant: F = EIAJ SOIC package (Case 965), L1 = date code format indicating assembly week/year and wafer lot. This matches the ordering information in the datasheet where MC14011BF denotes the EIAJ SOIC version, and FL1 confirms compliance with the 14-pin EIAJ outline and tape-and-reel shipping configuration.
Is MC14011BFL1 pin-compatible with CD4011B devices?
Yes, MC14011BFL1 is explicitly specified as a pin-for-pin replacement for CD4011B and other B-suffix 4000-series NAND gates. The pin assignments (VDD = pin 14, VSS = pin 7, identical input/output mapping per gate) and footprint dimensions match exactly - enabling direct substitution in existing PCB layouts without modification.
