Product details
Overview
MC14001BFR1 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 control systems. It operates across a 3.0–18.0 VDC supply range, delivers ±10 mA output drive per pin, supports –55°C to +125°C ambient operation, and features buffered outputs capable of driving two low-power TTL loads.
For engineers reviewing the MC14001BFR1 datasheet, pinout, applications, or equivalent options, this device is selected for robust level-shifting, noise-tolerant combinational logic, and legacy CD4000-series drop-in replacement in battery-powered and wide-voltage embedded controllers.
Technical Context
The MC14001BFR1 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 (VOL ≤ 0.05 V, VOH ≥ 4.95 V at VDD = 5 V), with input thresholds (VIL = 1.5 V, VIH = 3.5 V) ensuring >1.0 V DC noise margin under 5 V operation.
Switching performance is load-dependent: propagation delay ranges from 40 ns to 250 ns (CL = 50 pF, VDD = 5–15 V), while rise/fall times scale linearly with capacitive load per published formulas (e.g., tPLH = 0.26 ns/pF × CL + 27 ns at VDD = 15 V). Unused inputs must be tied to VSS for NOR functionality.
Key Specifications

|---|---|
| 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 direct interface with 3.3 V, 5 V, 12 V, and 15 V systems without level shifters |
| Output Drive Capability | ±10 mA per pin - sufficient to drive two low-power TTL loads or one low-power Schottky TTL load over full temperature range |

Pinout & Package
MC14001BFR1 is supplied in a 14-pin SOIC package (Case 751A, D suffix), measuring 8.75 mm × 4.00 mm × 1.75 mm. Pin 7 is VSS (ground), pin 14 is VDD (supply), and pins 1, 2, 4, 5, 8, 9, 12, 13 are dedicated to four independent NOR gate inputs/outputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN 1A | First input of Gate A - must be tied to VSS if unused to prevent floating node and increased power consumption |
| 2 | IN 2A | Second input of Gate A - forms standard NOR truth table: output low only when both inputs high |
| 3 | OUTA | Output of Gate A - buffered, rail-to-rail CMOS swing, capable of sourcing/sinking up to ±10 mA |
| 4 | IN 1B | First input of Gate B - electrically isolated from other gates; shares no internal nodes |
| 5 | IN 2B | Second input of Gate B - identical electrical characteristics to IN 1A/IN 2A |
| 6 | OUTB | Output of Gate B - independently driven; no crosstalk with OUTA or other outputs |
| 7 | VSS | Ground reference - all internal circuitry referenced to this pin; mandatory connection for proper biasing |
| 8 | OUTC | Output of Gate C - matches OUTA/OUTB in drive strength, voltage levels, and timing behavior |
| 9 | IN 1C | First input of Gate C - same input capacitance (Cin = 7.5 pF) and leakage (<±0.1 µA) as all inputs |
| 10 | IN 2C | Second input of Gate C - compatible with TTL, CMOS, and open-collector drivers |
| 11 | OUTD | Output of Gate D - final gate output; fully specified for fan-out, noise immunity, and switching speed |
| 12 | IN 1D | First input of Gate D - requires external pull-down to VSS if unused to maintain defined logic state |
| 13 | IN 2D | Second input of Gate D - no internal protection diodes beyond double-diode input clamping |
| 14 | VDD | Positive supply - powers all four gates; decoupling capacitor recommended within 1 cm of this pin |

Use Scenario: Controlling startup order of multiple voltage rails (e.g., 12 V → 5 V → 3.3 V) in programmable logic controllers. IC Role / Device Role / Timing Role: NOR gate C acts as a delayed enable gate triggered by power-good signals from upstream regulators. Use Value: Ensures strict sequencing compliance via rail-to-rail output swing and noise-immune inputs, eliminating need for external comparators. |

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 quad 2-input NOR function but rated only to +85°C; higher typical propagation delay (150 ns vs. 125 ns at 5 V) | Limited to commercial/industrial environments without extended temperature requirements | Select CD4001BE only for cost-sensitive, non-automotive applications where –55°C to +125°C operation is unnecessary |
| 74HC02DR | Higher speed (19 ns typical tPD at 5 V) but narrower supply range (2–6 V); not 12 V tolerant | Suitable for 3.3 V/5 V FPGA/CPU I/O expansion, not for mixed-voltage or automotive use | Choose 74HC02DR when nanosecond-speed logic is required and system operates strictly within 2–6 V supply envelope |
Compared with CD4001BE and 74HC02DR, the MC14001BFR1 uniquely balances wide-voltage operation (3–18 V), extended temperature range (–55°C to +125°C), and proven reliability in safety-critical automotive subsystems - making it irreplaceable where voltage flexibility and ruggedness outweigh raw speed.

FAQ
What is the maximum supply voltage rating for the MC14001BFR1?
The MC14001BFR1 has an absolute maximum DC supply voltage (VDD) rating of +18.0 V, with operational specification guaranteed from 3.0 V to 18.0 V. Exceeding 18.0 V risks permanent damage per the Absolute Maximum Ratings table. The device maintains full functionality-including output drive, noise margin, and propagation delay-across this entire range, making MC14001BFR1 suitable for 12 V automotive and 15 V industrial bus interfaces.
Can the MC14001BFR1 directly drive a standard TTL load?
Yes, the MC14001BFR1 is explicitly rated to drive two low-power TTL loads or one low-power Schottky TTL load over its full –55°C to +125°C operating range. Its output drive capability (IOL = 4.2 mA, IOH = –4.2 mA at VDD = 15 V) exceeds the input current requirements of LP-TTL (IIL = –1.6 mA, IIH = 40 µA), confirming direct interfacing without buffer stages. This capability is validated in the Electrical Characteristics table and applies to MC14001BFR1 specifically.
How should unused inputs be handled on the MC14001BFR1?
All unused inputs on the MC14001BFR1 must be tied to VSS (ground), as it is a NOR gate device. This requirement is explicitly stated in the datasheet's "Unused inputs must always be tied to an appropriate logic voltage level" guidance and reinforced in Figure 1's footnote: "All unused inputs of OR, NOR gates must be connected to VSS." Leaving inputs floating causes increased quiescent current, erratic switching, and potential thermal overstress due to partial conduction in the CMOS pair.
Is the MC14001BFR1 pin-compatible with the CD4001B?
Yes, the MC14001BFR1 is specified as a pin-for-pin replacement for the CD4001B, as confirmed in the datasheet's "Pin–for–Pin Replacements for Corresponding CD4000 Series B Suffix Devices" section. Both devices share identical 14-pin SOIC pinout (IN1A, IN2A, OUTA, ..., VDD, VSS), identical logic function, and compatible electrical characteristics-enabling drop-in substitution in legacy CD4001B designs without PCB modification or firmware changes.
What is the typical propagation delay of the MC14001BFR1 at 5 V supply and 50 pF load?
The typical propagation delay (tPLH/tPHL) of the MC14001BFR1 at VDD = 5 V and CL = 50 pF is 125 ns, as listed in the Switching Characteristics table. This value represents the time between 50% input transition and 50% output transition under standard test conditions. The datasheet also specifies a maximum delay of 250 ns under worst-case conditions (–55°C, VDD = 5 V), providing design margin for timing-critical applications using MC14001BFR1.
