Product details
Overview
MC14011UBD 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 systems. It operates across 3.0–18.0 VDC supply, delivers ±10 mA output drive per pin, exhibits 5.0 pF typical input capacitance, and supports ambient temperatures from −55 °C to +125 °C - enabling use in battery-powered instrumentation and harsh-environment control logic.
For engineers reviewing the MC14011UBD datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SOIC-14 package mapping, temperature-rated switching performance (tPLH/tPHL ≤ 80 ns at 15 V), and validated alternatives for legacy CMOS logic replacement.
Technical Context
The MC14011UBD implements four independent 2-input NAND gates using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors on a single monolithic die. Its unbuffered architecture ensures direct logic-level compatibility with CD4000-series devices while maintaining rail-to-rail output swing and high input impedance.
Each gate features double-diode input protection, requires unused inputs tied to VDD or VSS, and draws only 0.25–1.0 µA quiescent current per package at 25 °C. Propagation delay scales linearly with load capacitance (e.g., tPLH = 0.50 ns/pF × CL + 15 ns at VDD = 15 V), supporting predictable timing in mixed-voltage digital interfaces.
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 and battery-backed operation without level-shifting. |
| 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 Capacitance | 5.0 pF typical - minimizes capacitive loading on preceding stages and preserves high-frequency signal integrity. |
| Propagation Delay | 40 ns max at VDD = 15 V, CL = 50 pF - enables reliable operation up to ~5 MHz toggle frequency in synchronous logic designs. |
| Quiescent Current | 0.25 µA typical at 5 V, 25 °C - reduces standby power in always-on monitoring circuits and portable equipment. |
| Operating Temperature | −55 °C to +125 °C - qualified for under-hood automotive, industrial PLC I/O, and aerospace subsystems. |
Pinout & Package
MC14011UBD is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package, case 751A, with Pb-free finish and moisture sensitivity level (MSL) 1. The package measures 8.55–8.75 mm × 3.80–4.00 mm × 1.35–1.75 mm (L × W × H), compatible with standard surface-mount reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 8, 9, 12, 13 | Input (IN1A–IN2D) | Eight dedicated CMOS logic inputs - each internally protected by dual diodes; must be tied to VDD if unused (NAND function). |
| 3, 4, 10, 11 | Output (OUTA–OUTD) | Four push-pull CMOS outputs - rail-to-rail swing, capable of sourcing/sinking ≥0.36 mA at VOL = 0.4 V (VDD = 5 V). |
| 7 | VSS (Ground) | Primary ground reference - all internal circuitry referenced to this node; must be low-impedance connection. |
| 14 | VDD (Supply) | Positive supply rail - accepts 3.0–18.0 VDC; decoupling capacitor (0.1 µF) recommended adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Pin-for-pin replacement for CD4011B | Direct drop-in upgrade path for legacy CD4000-series designs - no PCB or firmware changes required. |
| Double-diode input protection | Robust ESD tolerance (>2 kV HBM) and transient immunity - eliminates need for external clamping in noisy environments. |
| Wide supply voltage range | Single part supports 5 V, 12 V, and 15 V logic domains - simplifies BOM consolidation across product variants. |
| High noise immunity | Input threshold ratios (VIH/VIL) scale with VDD - maintains >40% noise margin across full 3–18 V operating range. |
| Pb-free and RoHS compliant | Meets global environmental regulations - suitable for export-controlled and consumer-grade electronics manufacturing. |
Applications
| Industrial Control Logic | Automotive Body Electronics |

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, but narrower 3–15 V supply range and higher quiescent current (1 µA typical); not AEC-Q100 qualified. | Limited to commercial/industrial temperature range (−40 °C to +85 °C); lacks automotive qualification and Pb-free compliance. | Select when cost is primary constraint and automotive qualification or extended temperature operation is unnecessary. |
| 74HC00DR | TTL-compatible 74HC family; 2–6 V supply only; faster propagation (15 ns typ), but lower noise margin and no input protection diodes. | Requires level-shifting above 6 V; unsuitable for direct 12/15 V operation or high-noise industrial settings without added protection. | Choose for high-speed 5 V digital systems where speed outweighs supply flexibility and ruggedness requirements. |
Compared with CD4011BE and 74HC00DR, MC14011UBD uniquely combines 3–18 V operation, −55 °C to +125 °C rating, built-in input protection, and automotive qualification - making it the only option for robust, wide-supply, high-reliability NAND logic in mission-critical embedded systems.

FAQ
What is the maximum operating supply voltage for MC14011UBD?
The MC14011UBD supports a DC supply voltage range of −0.5 V to +18.0 V referenced to VSS. Its absolute maximum rating is +18.0 VDC; operation beyond this risks permanent damage. For reliable long-term use, the recommended range remains 3.0 VDC to 18.0 VDC as specified in the onsemi datasheet Rev. 11.
Does MC14011UBD require external pull-up or pull-down resistors on unused inputs?
No - unused inputs on MC14011UBD must be tied directly to VDD (not via resistors) because it is a NAND gate. This ensures defined logic-high states and prevents floating inputs from causing excessive current draw or oscillation. The datasheet explicitly prohibits leaving inputs unconnected or using weak biasing networks.
Is MC14011UBD pin-compatible with the CD4011B series?
Yes - MC14011UBD is specified as a pin-for-pin replacement for corresponding CD4000-series UB-suffix devices, including CD4011B. Both share identical SOIC-14 pin assignments, logic function, and electrical interface characteristics, enabling direct substitution without layout modification.
What is the typical input capacitance of MC14011UBD and how does it affect high-frequency operation?
The MC14011UBD exhibits a typical input capacitance of 5.0 pF per input pin. At 10 MHz, this results in ~315 Ω capacitive reactance at 5 V - low enough to avoid significant signal degradation in most CMOS-driven interfaces. However, designers should limit trace length and avoid daisy-chaining more than two inputs per gate to maintain timing integrity.
Can MC14011UBD be used in automotive applications requiring AEC-Q100 qualification?
The MC14011UBD itself is not AEC-Q100 qualified; however, its automotive-grade variant NLV14011UBDR2G is fully AEC-Q100 qualified and PPAP capable. For automotive body electronics or under-hood modules requiring formal qualification, the NLV prefix version must be selected - MC14011UBD is intended for industrial and general-purpose applications.
