Product details
Overview
MC14001UBDR2 from onsemi is a quad 2-input NOR 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 VDC supply, delivers ±10 mA output drive per pin, supports −55°C to +125°C ambient range, and features double diode input protection. It serves as a core combinational logic element in power management sequencers, sensor interface state machines, and fault-detection circuits.
For engineers reviewing the MC14001UBDR2 datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SOIC-14 package mapping, temperature-rated electrical performance, and validated alternative options for NOR gate replacement in legacy 4000-series designs.
Technical Context
The MC14001UBDR2 implements four independent 2-input NOR gates using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors on a single monolithic die. Its unbuffered architecture ensures minimal propagation delay variation with load and supply voltage.
Each gate exhibits rail-to-rail output swing (VOL ≤ 0.05 V at VDD = 5 V; VOH ≥ 4.95 V), defined input thresholds (VIL ≤ 1.0 V, VIH ≥ 4.0 V at VDD = 5 V), and guaranteed operation up to 125°C with quiescent current ≤ 1.0 µA per package at 15 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NOR gate - enables compact implementation of OR-invert logic without external inverters |
| Supply Voltage Range | 3.0 V to 18.0 V DC - supports wide-input industrial rails and battery-backed systems |
| Operating Temperature | −55°C to +125°C - qualified for under-hood automotive and harsh-environment industrial use |
| Output Drive (Sink) | Min 0.36 mA at VOL = 0.4 V, VDD = 5 V - sufficient to directly drive LED indicators or TTL inputs |
| Propagation Delay | Max 180 ns at VDD = 5 V, CL = 50 pF - predictable timing for synchronous control logic below 1 MHz |
| Input Protection | Double diode clamping on all inputs - prevents latch-up and ESD damage in noisy environments |
| Quiescent Current | Max 30 µA at VDD = 15 V, TA = 125°C - enables ultra-low standby power in always-on monitoring circuits |
Pinout & Package
MC14001UBDR2 is housed in a Pb-free SOIC-14 (Case 751A) package measuring 8.55–8.75 mm × 3.80–4.00 mm × 1.35–1.75 mm, with 1.27 mm pitch and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 8, 9, 12, 13 | Input (IN1A–IN2D) | Eight dedicated gate inputs - each pair (e.g., Pin 1 & 2) feeds one NOR gate |
| 3, 4, 10, 11 | Output (OUTA–OUTD) | Four independent NOR outputs - open-drain compatible when pulled up externally |
| 7 | VSS | Ground reference - all unused inputs must be tied to VSS to prevent floating states |
| 14 | VDD | Positive supply - supplies entire quad gate array; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Pb-free & RoHS compliant | Meets global environmental regulations without requiring leaded solder process changes |
| Pin-for-pin replacement for CD4001UB | Direct drop-in upgrade path for legacy 4000-series designs without PCB revision |
| High noise immunity | Input hysteresis and rail-to-rail swing reduce susceptibility to EMI in motor-control environments |
| Low dynamic power | Total supply current scales linearly with frequency (e.g., ~0.3 µA/kHz at VDD = 5 V), minimizing heat in dense logic arrays |
| AEC-Q100 qualified (NLV variant) | Validated reliability for automotive applications - MC14001UBDR2 shares same die and process as NLV14001UBDR2G |
Applications
| Industrial Power Sequencing | Automotive Fault Detection |
|---|---|
Use Scenario: Controlling startup order of multiple DC/DC converters in programmable power supplies. IC Role / Device Role / Timing Role: NOR gate implements AND-NOT logic to enforce enable/disable dependencies between regulators. Use Value: Ensures safe ramp-up sequence by asserting downstream enables only after upstream rails stabilize - avoids inrush current faults. |
Use Scenario: Monitoring redundant sensor inputs (e.g., dual brake pressure sensors) in ADAS ECUs. IC Role / Device Role / Timing Role: NOR gate detects mismatched logic states indicating sensor disagreement or open-circuit failure. Use Value: Generates immediate fault flag without microcontroller intervention - meets ASIL-B diagnostic response time requirements. |
| Legacy System Logic Refresh | Low-Power Sensor Interface |
Use Scenario: Replacing obsolete CD4001BE in field-deployed metering hardware. IC Role / Device Role / Timing Role: Direct pin-compatible NOR gate substitution preserving existing timing margins and layout. Use Value: Eliminates obsolescence risk while maintaining identical logic behavior and reducing system-level power by >50% at 5 V. |
Use Scenario: Level-shifting and signal conditioning for MEMS accelerometer interrupts in battery-powered IoT nodes. IC Role / Device Role / Timing Role: NOR gate combines interrupt and sleep-mode signals to gate wake-up events. Use Value: Reduces average current draw to <1 µA during deep-sleep mode by disabling peripheral clocks via active-low enable. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4001BM96 | Same 3–18 V range but higher max IDD (5 µA at 125°C); no AEC-Q100 qualification; wider propagation delay spread (250 ns max at 5 V) | Limited to commercial-temperature industrial equipment; not suitable for automotive under-hood deployment | Select when cost is primary constraint and extended temperature or automotive qualification is unnecessary |
| 74HC02DR | Narrower VCC range (2–6 V); faster speed (21 ns max at 4.5 V); lower drive (±4 mA); no input protection diodes | Requires level-shifting for 12 V systems; unsuitable for direct connection to noisy sensors or long traces | Choose for high-speed, low-voltage logic in consumer electronics where noise immunity is secondary |
Compared with MC14001UBDR2, CD4001BM96 offers lower unit cost but sacrifices automotive qualification and thermal stability, while 74HC02DR delivers superior speed at the expense of supply flexibility and ruggedness - making MC14001UBDR2 the optimal choice for wide-voltage, high-reliability NOR logic in industrial and automotive contexts.

FAQ
What is the exact logic function implemented by MC14001UBDR2?
The MC14001UBDR2 integrates four independent 2-input NOR gates in a single SOIC-14 package. Each gate outputs LOW only when at least one input is HIGH; otherwise, it outputs HIGH. This unbuffered CMOS implementation matches the truth table of standard NOR logic and is electrically identical to the CD4001UB series, enabling direct functional replacement in legacy designs.
Does MC14001UBDR2 support automotive-grade applications?
While the MC14001UBDR2 itself is not AEC-Q100 certified, it shares the same die, process, and specifications as the NLV14001UBDR2G variant, which is explicitly qualified to AEC-Q100 Grade 1 (−40°C to +125°C) and PPAP capable. Designers may use MC14001UBDR2 in non-safety-critical automotive subsystems, but for ASIL-compliant applications, the NLV prefix version is required.
What are the absolute maximum ratings for MC14001UBDR2?
The MC14001UBDR2 has an absolute maximum DC supply voltage of −0.5 V to +18.0 V referenced to VSS, input/output voltage range of −0.5 V to VDD + 0.5 V, and continuous input/output current limit of ±10 mA per pin. Exceeding these values risks permanent damage. The device also specifies a maximum power dissipation of 500 mW at TA ≤ 65°C, derating linearly above that temperature.
How should unused inputs be handled on MC14001UBDR2?
All unused inputs on the MC14001UBDR2 must be tied to VSS (ground), as specified in the datasheet. This is mandatory because the MC14001UBDR2 implements NOR logic - floating inputs can cause unpredictable output states, increased power consumption, or oscillation due to high-impedance CMOS inputs. Tying to VDD would force the gate output LOW regardless of other input states.
Is MC14001UBDR2 pin-compatible with CD4001BE?
Yes, MC14001UBDR2 is pin-for-pin compatible with CD4001BE and other CD4001UB suffix devices. Both share identical SOIC-14 pin assignments: VDD on Pin 14, VSS on Pin 7, and matching input/output mapping across Pins 1–6 and 8–13. This allows direct replacement without PCB modification, provided the wider supply range (3–18 V vs. 3–15 V) and improved noise immunity of MC14001UBDR2 are accounted for in system validation.
