Product details
Overview
MC14001BFL1 from onsemi is a quad 2-input NOR gate CMOS logic IC designed for low-power, high-noise-immunity digital control and signal conditioning in industrial and automotive systems. It operates across a 3.0–18 VDC supply range, delivers ±10 mA output drive per pin, features buffered outputs, and supports operation from –55°C to +125°C - enabling use in battery-powered instrumentation and harsh-environment timing circuits.
For engineers reviewing the MC14001BFL1 datasheet, pinout, applications, or equivalent options, this device is selected for robust level-shifting, discrete logic synthesis, and noise-tolerant interface buffering where wide-voltage compatibility and static immunity are critical.
Technical Context
The MC14001BFL1 implements four independent 2-input 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 (e.g., VIH = 3.5 V at 5 V, 11 V at 15 V), and guaranteed DC noise margins of 1.0 V (5 V), 2.0 V (10 V), and 2.5 V (15 V).
It features double diode input protection (except triple on select variants), is pin-for-pin compatible with CD4001B, and drives two low-power TTL loads or one low-power Schottky TTL load over its full temperature range. Unused inputs must be tied to VSS (NOR) to prevent floating-state instability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input NOR gate - provides four independent OR-NOT functions for combinational logic synthesis. |
| Supply Voltage Range | 3.0 VDC to 18 VDC - enables direct interfacing with 3.3 V, 5 V, 12 V, and 15 V systems without level shifters. |
| Output Drive Current | ±10 mA per pin (max) - sufficient to directly drive LEDs, small relays, or multiple CMOS/TTL inputs. |
| Input Thresholds (VDD = 5 V) | VIL ≤ 1.5 V, VIH ≥ 3.5 V - ensures >1.0 V DC noise margin against supply ripple or crosstalk. |
| Propagation Delay (CL = 50 pF) | 40–250 ns (typ–max at VDD = 15 V) - supports reliable operation up to ~1–2 MHz in simple gating applications. |
| Quiescent Supply Current | 0.25 µA at 5 V (25°C) - enables ultra-low standby power in battery-backed control modules. |
| Operating Temperature | –55°C to +125°C - qualified for under-hood automotive, industrial PLC I/O, and aerospace subsystems. |
Pinout & Package
MC14001BFL1 is supplied in a 14-lead plastic EIAJ SOIC package (Case 965, F suffix), measuring 9.90–10.50 mm × 5.10–5.45 mm × 1.42 mm max height, with 1.27 mm lead pitch and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 8, 9 | NOR Gate Input A/B | Two dedicated inputs per gate; unused NOR inputs must be tied to VSS to avoid undefined output state. |
| 3, 4, 10, 11 | NOR Gate Output | Buffered CMOS outputs capable of rail-to-rail swing and ±10 mA sourcing/sinking. |
| 7 | VSS | Ground reference for all gates; required return path for logic and supply current. |
| 14 | VDD | Positive supply rail (3–18 V); decoupling capacitor recommended near this pin. |
| 5, 6, 12, 13 | NOR Gate Input A/B | Second set of inputs per gate; identical electrical behavior to pins 1/2/8/9. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3.0–18 VDC operation eliminates need for separate voltage regulators in mixed-supply systems. |
| Rail-to-Rail Outputs | VOH ≥ VDD – 0.05 V and VOL ≤ 0.05 V ensure full logic swing and maximum noise margin at any supply. |
| High Noise Immunity | Guaranteed 1.0–2.5 V DC noise margin across 5–15 V supplies reduces susceptibility to EMI in noisy environments. |
| Low Quiescent Power | 0.25–1.0 µA typical IDD at 5–15 V enables multi-year battery life in always-on sensor nodes. |
| Pin-Compatible Replacement | Direct drop-in replacement for CD4001B - simplifies legacy design upgrades without PCB changes. |
Applications
| Industrial Control Logic | Automotive Body Electronics |
|---|---|
Use Scenario: Discrete safety interlock logic in programmable logic controller (PLC) I/O modules. IC Role / Device Role / Timing Role: Quad NOR gate implements hardware-level AND-OR-NOT safety chains independent of firmware.

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 (250–500 ns typ at 5 V), higher quiescent current (1–5 µA). | Lower speed and higher power make it less suitable for high-frequency clocked logic but acceptable for slow control signals. | Select when cost sensitivity outweighs performance requirements and legacy CD4000-series qualification is mandatory. |
| 74HC02D | CMOS variant with 2–6 V supply range only; faster propagation (15–25 ns typ), lower noise margin (0.9 V at 5 V). | Not rated for >6 V or –55°C operation; unsuitable for automotive or industrial 12 V systems without level shifting. | Choose only for 3.3/5 V consumer-grade designs requiring higher speed and lower capacitance loading. |
Compared with CD4001BE and 74HC02D, MC14001BFL1 uniquely balances wide-voltage operation (3–18 V), extreme temperature tolerance (–55°C to +125°C), and sub-microamp quiescent current - making it the sole choice for unregulated, high-reliability embedded control where supply and environment are unconstrained.

FAQ
What is the absolute maximum supply voltage for MC14001BFL1?
The absolute maximum DC supply voltage (VDD) for MC14001BFL1 is +18.0 V, with a minimum of –0.5 V relative to VSS. Exceeding +18.0 V risks permanent damage per the Absolute Maximum Ratings table. Operation within the recommended 3.0–18.0 V range ensures full specification compliance across temperature.
How should unused inputs be handled on MC14001BFL1?
All unused inputs on MC14001BFL1 must be tied to VSS (ground), because it is a NOR gate. Leaving inputs floating can cause excessive supply current, thermal instability, or oscillation due to CMOS input stage sensitivity. This requirement is explicitly stated in the datasheet's "Unused inputs must always be tied to an appropriate logic voltage level" guidance.
Is MC14001BFL1 pin-compatible with CD4001B devices?
Yes, MC14001BFL1 is specified as a pin-for-pin replacement for corresponding CD4001B-series devices. Its pinout matches CD4001BE exactly: VDD on pin 14, VSS on pin 7, and identical gate input/output assignments across pins 1–13. No PCB layout change is required for migration.
What is the output drive capability of MC14001BFL1 at 12 V supply?
At VDD = 12 V, MC14001BFL1 guarantees ±4.2 mA output sink/source current (IOL/IOH) while maintaining VOL ≤ 1.5 V and VOH ≥ 10.5 V. This allows direct driving of two low-power TTL loads or one low-power Schottky TTL load across the full –55°C to +125°C operating range.
Does MC14001BFL1 include input protection diodes?
Yes, MC14001BFL1 includes double diode protection on all inputs to guard against electrostatic discharge and transient overvoltage. This protection is standard across the B-Series and is explicitly noted in the "Device Description" section of the datasheet - distinguishing it from variants like MC14011B which feature triple diode protection.
