Product details
Overview
MC14001BFL2 from ON Semiconductor is a quad 2-input NOR gate CMOS logic IC designed for low-power, high-noise-immunity digital systems. It operates across a 3.0–18.0 VDC supply range, delivers ±10 mA output drive per pin, features buffered outputs, and supports operation from –55°C to +125°C - ideal for industrial control panels requiring robust noise rejection in mixed-signal environments.
For engineers reviewing the MC14001BFL2 datasheet, pinout, applications, or equivalent options, this device is selected for voltage-flexible combinational logic where static power consumption below 1 µA per gate at 5 V and guaranteed DC noise margins (≥1.0 V at 5 V) are critical design requirements.
Technical Context
The MC14001BFL2 implements four independent NOR gates using complementary P- and N-channel enhancement-mode MOSFETs in a monolithic CMOS structure. Each gate exhibits rail-to-rail output swing, input thresholds that scale with VDD (VIH = 3.5 V min at 5 V), and inherent latch-up immunity due to its isolated well construction.
It supports direct interfacing with TTL loads - driving two low-power TTL inputs or one low-power Schottky TTL load over full temperature range - and requires unused inputs tied to VSS (for NOR function) to prevent floating-node instability and increased quiescent current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NOR gate - provides four independent OR-NOT operations per package |
| Supply Voltage Range | 3.0 VDC to 18.0 VDC - enables single-supply operation across battery, industrial, and legacy 5/12/15 V systems |
| Output Drive | ±10 mA per pin - sufficient to directly drive LP-TTL loads without external buffers |
| Input Thresholds | VIL ≤ 1.5 V, VIH ≥ 3.5 V at VDD = 5 V - ensures >1.0 V DC noise margin under nominal conditions |
| Quiescent Current | 0.25 µA typical at 5 V, 25°C - enables ultra-low standby power in battery-backed logic |
| Operating Temperature | –55°C to +125°C - qualified for extended industrial and automotive under-hood applications |
| Propagation Delay | 125 ns max at 5 V, CL = 50 pF - defines maximum combinational path timing for synchronous design |
Pinout & Package
MC14001BFL2 is supplied in a 14-pin plastic EIAJ SOIC package (Case 965, F suffix), with 0.65 mm lead pitch and body dimensions of 9.90 × 5.10 mm. Pin 1 is marked by a beveled corner or notch; pin 7 is VSS (ground); pin 14 is VDD (supply).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 8, 9 | Input A/B per gate | Two dedicated inputs per NOR gate - all four gates share identical dual-input topology |
| 3, 4, 10, 11 | Output per gate | Buffered CMOS output - rail-to-rail swing, no external pull-ups required |
| 7 | VSS | Ground reference for all internal circuitry - must be connected to system ground plane |
| 14 | VDD | Positive supply input - decoupling capacitor (0.1 µF) recommended within 10 mm |
| 5, 6, 12, 13 | Unused pins (NC) | No internal connection - must remain unconnected; not bonded or functional |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (3–18 V) | Eliminates need for level-shifting in multi-voltage systems - supports direct use with 3.3 V, 5 V, and 12 V rails |
| Double diode input protection | Prevents damage from ESD transients up to ±2 kV HBM without external clamping |
| Pin-for-pin compatible with CD4001B | Enables drop-in replacement in legacy designs without PCB revision or layout change |
| Low dynamic current (0.3 µA/kHz per gate) | Reduces total supply current in clocked logic - e.g., <10 µA at 10 kHz with 50 pF load |
| Guaranteed noise margins | Minimum 1.0 V (5 V), 2.0 V (10 V), 2.5 V (15 V) - ensures reliable operation in electrically noisy enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4001BE | Same logic function and pinout; wider propagation delay (250 ns max at 5 V), higher quiescent current (100 nA typical) | Lower speed and higher static power - suitable only for sub-100 kHz logic or cost-sensitive non-industrial use | Select CD4001BE only when legacy qualification or lower unit cost outweighs performance and temperature requirements. |
| 74HC02D | Higher speed (15 ns typ at 5 V), narrower supply range (2–6 V), no extended temperature support (–40°C to +125°C only) | Not rated for –55°C operation or 12–15 V supplies - unsuitable for military, aerospace, or legacy industrial systems | Choose 74HC02D for high-speed consumer or commercial designs where 5 V rail stability is guaranteed. |
Compared with CD4001BE and 74HC02D, the MC14001BFL2 uniquely balances wide voltage operation (3–18 V), extended temperature range (–55°C to +125°C), and proven reliability in harsh environments - making it the preferred choice for industrial and automotive logic where supply variation and thermal stress are design constraints.

FAQ
What is the maximum operating supply voltage for the MC14001BFL2?
The MC14001BFL2 has a maximum DC supply voltage (VDD) rating of +18.0 V, with absolute maximum ratings specifying –0.5 V to +18.0 V referenced to VSS. Operation beyond 18.0 V risks permanent damage to the internal CMOS structure, and sustained operation above 15 V should include thermal derating analysis per the datasheet's power dissipation curves.
Can unused inputs on the MC14001BFL2 be left floating?
No - all unused inputs on the MC14001BFL2 must be tied to VSS (ground). Because it is a NOR gate, floating inputs can cause elevated quiescent current, unpredictable output states, and increased susceptibility to noise-induced switching. The datasheet explicitly mandates connecting unused NOR inputs to VSS to ensure stable, low-power operation.
Is the MC14001BFL2 pin-compatible with the CD4001B series?
Yes - the MC14001BFL2 is specified as a pin-for-pin replacement for corresponding CD4001B-series devices. Its pin assignments (VDD = pin 14, VSS = pin 7, gate inputs/outputs mapped identically) match the CD4001B, enabling direct substitution in existing PCB layouts without modification.
What is the typical propagation delay of the MC14001BFL2 at 5 V supply?
At VDD = 5 V, CL = 50 pF, and TA = 25°C, the typical propagation delay (tPLH/tPHL) of the MC14001BFL2 is 125 ns, with a maximum guaranteed value of 250 ns. This delay is consistent across all four NOR gates and scales predictably with load capacitance per the formula tPLH = (0.90 ns/pF) × CL + 80 ns.
Does the MC14001BFL2 support operation at –55°C?
Yes - the MC14001BFL2 is fully specified and tested for operation across an ambient temperature range of –55°C to +125°C. This extended range is confirmed in the Absolute Maximum Ratings table and supported by electrical characterization data across all three temperature extremes, making it suitable for aerospace, military, and extreme-environment industrial use.
