Product details
Overview
MC14011UBDG from onsemi is a quad 2-input NAND gate CMOS logic IC designed for low-power, high-noise-immunity digital control and signal conditioning. It operates across 3.0–18 VDC supply, delivers ±10 mA output drive, supports −55°C to +125°C ambient, and features double diode input protection. It is used in industrial timing circuits, battery-powered sensor interfaces, and legacy system logic upgrades.
For engineers reviewing the MC14011UBDG datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SOIC-14 package mapping, temperature-rated electrical specs, real-world use scenarios, and two validated alternative parts with documented technical and application differences.
Technical Context
The MC14011UBDG 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, high input impedance, and symmetrical propagation delays (tPLH/tPHL = 40–180 ns at VDD = 5–15 V, CL = 50 pF).
It requires unused inputs tied to VDD (for NAND), supports dynamic loading up to 50 pF per gate, and draws only 0.0005–0.0015 A quiescent current per package at 25°C - enabling direct interface with TTL loads without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NAND - enables compact implementation of combinational logic, enable/disable control, and active-low decoding. |
| Supply Voltage Range | 3.0 VDC to 18 VDC - allows operation from single Li-ion cells up to industrial 12–15 V rails without regulation. |
| Output Drive | ±10 mA per pin - sufficient to directly drive two low-power TTL loads or one LS-TTL load across full temperature range. |
| Propagation Delay | 40–180 ns (VDD = 5–15 V, CL = 50 pF) - supports reliable operation up to ~1–2 MHz toggle rates in buffered configurations. |
| Quiescent Current | 0.5–1.0 μA typical at 25°C - enables multi-year battery life in always-on monitoring nodes. |
| Input Protection | Double diode clamping on all inputs - prevents latch-up and ESD damage during hot-plug or noisy environment operation. |
| Operating Temp | −55°C to +125°C - qualified for under-hood automotive, industrial motor controls, and outdoor infrastructure. |
Pinout & Package
MC14011UBDG is housed in a 14-pin SOIC-14 (Case 751A) package, 8.55–8.75 mm × 3.80–4.00 mm footprint, 1.27 mm pitch, Pb-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 8, 9, 12, 13 | Input (IN1A–IN2D) | Four independent NAND gate inputs; must be tied to VDD if unused to prevent floating states. |
| 3, 4, 10, 11 | Output (OUTA–OUTD) | Open-drain-capable CMOS outputs; rail-to-rail swing with no external pull-ups required. |
| 7 | VSS (Ground) | Primary ground reference for all gates; decoupling capacitor placement critical for noise immunity. |
| 14 | VDD (Supply) | Single positive supply input; accepts 3–18 VDC; requires local 0.1 μF ceramic bypass near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3.0–18 VDC operation eliminates need for dedicated logic regulators in mixed-voltage systems. |
| High Noise Immunity | Input thresholds scale with VDD (VIL ≈ 0.3×VDD, VIH ≈ 0.7×VDD), ensuring robustness against supply ripple and crosstalk. |
| Low Quiescent Power | Sub-microamp IDD enables use in energy-harvesting and ultra-low-duty-cycle wake-up circuits. |
| Pb-Free & RoHS | Meets global environmental compliance requirements without performance trade-offs or derating. |
| Pin-for-Pin CD4000 Compatibility | Direct drop-in replacement for legacy CD4011BE in existing SOIC-14 layouts and firmware. |

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 logic function and SOIC-14 package, but narrower 3–15 V supply range and higher 20 μA max IDD at 25°C. | Not qualified for automotive or extended-temp industrial use; lacks double-diode input protection. | Select when cost is primary and operating temperature stays within −40°C to +85°C. |
| NLV14011UBDR2G | Identical electrical specs and pinout; differs only in AEC-Q100 qualification, PPAP capability, and tape-and-reel packaging (2500 pcs). | Required for new automotive designs; supports full production traceability and zero-defect manufacturing protocols. | Select for OEM automotive programs or any application requiring certified reliability documentation. |
Compared with MC14011UBDG, CD4011BM96 offers lower unit cost but sacrifices high-temperature stability and ESD robustness, while NLV14011UBDR2G adds automotive-grade validation without altering circuit design - making it ideal for production ramp in vehicle ECUs.

FAQ
What is the maximum operating supply voltage for MC14011UBDG?
The MC14011UBDG supports a DC supply voltage range of −0.5 V to +18.0 V referenced to VSS. Its recommended operational range is 3.0 VDC to 18 VDC. Exceeding +18.0 V may cause permanent damage, and operation below 3.0 VDC risks unreliable logic thresholds and increased propagation delay. The absolute maximum rating ensures robustness during transient conditions, but sustained operation should remain within the specified 3–18 V window for guaranteed functionality and lifetime reliability of the MC14011UBDG.
Can MC14011UBDG directly drive a standard LED?
No, MC14011UBDG is not designed to directly drive standard LEDs. Its output sink current is rated up to 4.2 mA at VDD = 15 V (typical), and source current is limited to −3.5 mA (typical). Most indicator LEDs require 5–20 mA for visible brightness, exceeding the MC14011UBDG's safe output capability. Driving an LED directly risks violating the ±10 mA absolute maximum per-pin current rating and may degrade output transistor longevity. Use an external NPN transistor or dedicated LED driver stage when interfacing with LEDs in designs using the MC14011UBDG.
Is MC14011UBDG pin-compatible with CD4011BE?
Yes, MC14011UBDG is explicitly designed as a pin-for-pin replacement for CD4011BE in SOIC-14 packages. Both share identical pin assignments: VDD on pin 14, VSS on pin 7, and matching input/output placements for all four NAND gates. The MC14011UBDG improves upon the CD4011BE with wider supply range (up to 18 V vs. 15 V), lower quiescent current, double-diode input protection, and enhanced noise immunity - while maintaining full backward compatibility in existing layouts and schematics using the MC14011UBDG.
What is the recommended handling procedure for unused inputs on MC14011UBDG?
All unused inputs on MC14011UBDG must be tied to VDD (logic HIGH), as specified in the official onsemi datasheet. This prevents floating inputs - which can cause excessive supply current, oscillation, or unpredictable gate behavior due to high CMOS input impedance. Leaving inputs unconnected risks increased power dissipation, thermal stress, and potential device malfunction. Tying to VDD ensures stable logic state, minimizes noise susceptibility, and guarantees predictable NAND gate operation across temperature and voltage extremes for the MC14011UBDG.
Does MC14011UBDG support operation at −55°C?
Yes, MC14011UBDG is fully specified and guaranteed to operate over an ambient temperature range of −55°C to +125°C. Electrical characteristics including VOL, VOH, propagation delay, and output drive are validated across this full range per the onsemi datasheet. Its construction uses ruggedized CMOS processes and internal protection structures suited for extreme environments - making the MC14011UBDG suitable for aerospace, downhole instrumentation, and military-grade electronics where sub-zero startup and sustained low-temperature functionality are required.
