Product details
Overview
MC14001UBDG 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 3.0–18.0 VDC supply, delivers ±10 mA I/O 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 and sensor interface control circuits.
For engineers reviewing the MC14001UBDG datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SOIC-14 package mapping, temperature-rated drive capability, noise immunity specifications, and validated alternative options for legacy CMOS logic replacement.
Technical Context
The MC14001UBDG implements four independent 2-input NOR 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, with VOH ≥ 4.95 V at VDD = 5.0 V and VOL ≤ 0.05 V under load - enabling direct interfacing with TTL and Schottky loads.
Its input structure includes double diode protection and high-impedance CMOS inputs requiring explicit biasing: unused NOR inputs must be tied to VSS (GND), not left floating. Propagation delay ranges from 40 ns to 180 ns depending on VDD and load, with rise/fall times tightly specified per supply voltage (e.g., tTLH = 65 ns max at VDD = 15 V, CL = 50 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NOR gate - enables discrete OR-invert logic synthesis without external inverters |
| Supply Voltage Range | 3.0 VDC to 18.0 VDC - supports wide-input industrial rails and battery-backed systems |
| Operating Temperature | −55°C to +125°C - qualified for under-hood automotive and extended industrial environments |
| Output Drive | ±10 mA per pin - sufficient to drive two low-power TTL loads or one LS-TTL load across full temp range |
| Input Protection | Double diode clamping on all inputs - prevents ESD damage and transient overvoltage failure |
| Quiescent Current | 0.0015 A max at VDD = 15 V - ensures sub-microwatt standby power in always-on monitoring circuits |
| Propagation Delay | 40 ns min / 180 ns max (CL = 50 pF, TA = 25°C) - defines maximum toggle frequency in synchronous logic paths |
Pinout & Package
MC14001UBDG is housed in a 14-pin SOIC-NB (Small Outline Integrated Circuit – Narrow Body) package, case 751A-03, with 1.27 mm pitch, Pb-free finish, and JEDEC-standard footprint (D suffix). Dimensions: 8.55–8.75 mm × 3.80–4.00 mm × 1.35–1.75 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 8, 9, 12, 13 | NOR Gate Inputs (IN1A–IN2D) | Eight total inputs across four gates; each pair (e.g., pins 1+2) feeds one NOR gate |
| 3, 4, 10, 11 | NOR Gate Outputs (OUTA–OUTD) | Four buffered outputs; each drives downstream logic or discrete FET gates directly |
| 7 | VSS (Ground) | Common reference for all gates; unused inputs must tie here to ensure defined logic '0' |
| 14 | VDD (Supply) | Positive supply rail; powers all four gates simultaneously; decoupling capacitor required |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | VOH ≥ 4.95 V and VOL ≤ 0.05 V at VDD = 5.0 V - eliminates level-shifting in mixed-voltage systems |
| High noise immunity | VIL = 1.0 V and VIH = 4.0 V at VDD = 5.0 V - provides >3 V noise margin against EMI in motor-control environments |
| Pb-free & RoHS compliant | "G" suffix marking confirms lead-free terminations and compliance with EU Directive 2011/65/EU |
| Pin-for-pin CD4000 compatibility | Direct drop-in replacement for CD4001UB - preserves legacy PCB layouts and BOM continuity |
| Low dynamic power | IT = (0.8 µA/kHz)·f + IDD/N at VDD = 15 V - enables kHz-range clocking in energy-constrained remote sensors |
Applications
| Industrial Power Sequencing | Automotive Sensor Interface |
|---|---|
Use Scenario: Controlling startup order of multiple DC-DC converters in programmable power supplies. IC Role / Device Role / Timing Role: NOR gate implements enable/disable logic with priority arbitration between voltage rails. Use Value: Ensures safe power-up sequence by forcing dependent rails OFF until primary rail stabilizes - leveraging guaranteed VSS-tied input requirement. |
Use Scenario: Signal conditioning for dual-redundant brake pressure sensors in ADAS ECUs. IC Role / Device Role / Timing Role: NOR gate performs fault-detection voting: outputs LOW only when both sensors agree on fault state. Use Value: Delivers fail-safe logic decision with −55°C to +125°C operation and AEC-Q100-aligned robustness (via NLV variant lineage). |
| Legacy System Modernization | Low-Power IoT Edge Node |

IC Role / Device Role / Timing Role: Direct pin-compatible NOR logic block preserving original timing and fanout. Use Value: Eliminates redesign risk: same SOIC-14 footprint, identical truth table, and extended 18 V supply tolerance improves reliability. |
Use Scenario: Wake-up controller for battery-powered environmental monitors sampling every 5 minutes. IC Role / Device Role / Timing Role: NOR gate enables ultra-low-quiescent-current sleep mode by gating MCU reset line. Use Value: Achieves <1.5 µA total package IDD at 15 V - extends 10-year battery life in sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4001BE | Same logic function and pinout, but rated only to +85°C and lacks double-diode input protection | Not suitable for automotive or extended-temperature industrial use; requires external ESD protection | Select MC14001UBDG where ambient exceeds 85°C or system-level ESD robustness is mandatory |
| 74HC02DR | Higher speed (tPD ≈ 15 ns), but narrower 2–6 V supply range and no −55°C rating | Optimized for 3.3 V/5 V consumer electronics; unsuitable for 12 V automotive or wide-temp industrial rails | Choose MC14001UBDG when operating above 6 V or below −40°C is required |
Compared with CD4001BE and 74HC02DR, MC14001UBDG uniquely combines extended temperature range, wide supply tolerance, integrated input protection, and legacy CD4000 pin compatibility - making it the only option for drop-in modernization of high-reliability analog-adjacent logic.

FAQ
What is the maximum supply voltage for MC14001UBDG?
The MC14001UBDG 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, design within 3.0–18.0 VDC as specified in the electrical characteristics table - with derating applied above 65°C ambient per the datasheet's thermal notes.
Does MC14001UBDG require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs on MC14001UBDG must be tied directly to VSS (pin 7), not left floating. This is explicitly mandated because the device implements NOR logic: unconnected inputs default to undefined states that can cause excessive current draw, oscillation, or latch-up. The datasheet specifies "All unused inputs of OR, NOR gates must be connected to VSS," and MC14001UBDG falls under this rule.
Is MC14001UBDG pin-compatible with CD4001 series devices?
Yes - MC14001UBDG is a pin-for-pin replacement for CD4001UB and other CD4000-series UB-suffix NOR gates. Both share identical SOIC-14 pin assignments, logic function, and truth table. However, MC14001UBDG adds double-diode input protection and extends the operating temperature range to −55°C to +125°C, while maintaining backward compatibility with legacy PCB layouts.
What is the output drive capability of MC14001UBDG at 12 V supply?
At VDD = 12 V, MC14001UBDG delivers a minimum sink current (IOL) of 3.4 mA and a minimum source current (IOH) of −0.4 mA per output pin, as specified in the Electrical Characteristics table. These values ensure reliable driving of one Low-Power Schottky TTL load or two standard Low-Power TTL loads across the full −55°C to +125°C temperature range without derating.
Can MC14001UBDG be used in automotive applications?
While MC14001UBDG itself is not AEC-Q100 certified, its NLV-prefix variant NLV14001UBDG is fully qualified for automotive use. The MC14001UBDG shares identical electrical specs, SOIC-14 packaging, and thermal performance - and is widely deployed in non-safety-critical automotive subsystems (e.g., body control modules) where its −55°C to +125°C rating and robust input protection meet functional requirements.
