Product details
Overview
MC14071BFR2 from onsemi is a quad 2-input OR gate CMOS logic IC designed for low-power, high-noise-immunity digital signal combining in industrial control and instrumentation systems. It operates across 3.0–18 VDC supply, delivers ±10 mA output drive per pin, and features buffered outputs capable of driving two low-power TTL loads over –55°C to +125°C.
For engineers reviewing the MC14071BFR2 datasheet, pinout, applications, or equivalent options, key selection criteria include wide-voltage operation, rail-to-rail input thresholds, guaranteed noise margins (≥2.5 V at 15 V), and compatibility with legacy CD4000-series designs requiring EIAJ SOIC-14 packaging.
Technical Context
The MC14071BFR2 implements four independent non-inverting OR gates using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors in a monolithic structure. Each gate exhibits symmetric input voltage thresholds (VIH/VIL) that scale with VDD, enabling robust operation across its full 3–18 V range.
It integrates double diode input protection (except triple on NAND/AND variants), supports direct interfacing with TTL families via buffered outputs, and requires all unused inputs tied to VSS - consistent with OR/NOR topology requirements per datasheet guidance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input OR gate - provides four independent Boolean OR operations per package |
| Supply Voltage Range | 3.0 VDC to 18 VDC - enables single-supply operation across battery, industrial, and legacy logic rails |
| Input Thresholds (VDD = 15 V) | VIL ≤ 4.0 V, VIH ≥ 11 V - ensures ≥2.5 V DC noise margin for reliable switching in noisy environments |
| Output Drive (VDD = 15 V) | IOL = 4.2 mA, IOH = –4.2 mA - sufficient to drive two low-power TTL loads or one LS-TTL load |
| Propagation Delay (CL = 50 pF) | tPLH/tPHL ≤ 80 ns max at 15 V - supports medium-speed combinational logic up to ~10 MHz |
| Quiescent Current (VDD = 15 V) | ID D ≤ 1.0 µA - ultra-low static power ideal for battery-backed or energy-sensitive systems |
| Operating Temperature | –55°C to +125°C - qualified for extended industrial, automotive under-hood, and aerospace applications |
Pinout & Package
EIAJ SOIC-14 (Case 965-01) surface-mount package with 1.27 mm pitch; 9.90 × 5.10 × 1.42 mm body dimensions; lead-free and RoHS-compliant construction.

| 7 | VSS | Ground reference - all unused OR inputs must be tied to this pin |
| 14 | VDD | Positive supply - decoupling capacitor required within 10 mm for stable operation |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3.0–18 VDC operation eliminates need for level-shifting in mixed-voltage systems |
| Rail-Scaled Input Thresholds | VIH/VIL track VDD proportionally - maintains consistent noise immunity across voltage range |
| Buffered Outputs | Reduces propagation delay variation and improves fan-out capability vs unbuffered gates |
| High Noise Immunity | Guaranteed 2.5 V noise margin at 15 V - critical for industrial PLC I/O and motor control feedback paths |

Applications
| Industrial Control Logic | Power Sequencing Monitor |
|---|---|
Use Scenario: Combining multiple sensor fault signals (e.g., overtemperature, overcurrent, airflow loss) into a single system shutdown request line. IC Role / Device Role / Timing Role: OR gate performing wired-OR summation of active-high fault flags. Use Value: Eliminates discrete diode-OR networks; reduces BOM count and layout area while maintaining fail-safe response. | Use Scenario: Validating correct power-up sequence across multiple rails (e.g., 12 V → 5 V → 3.3 V) before enabling microcontroller reset. IC Role / Device Role / Timing Role: OR gate detecting any rail out-of-tolerance condition to assert global power-fail flag. Use Value: Leverages wide VDD range to monitor rails directly without external level shifters or voltage dividers. |

IC Role / Device Role / Timing Role: OR gate enabling MCU wake-on-any-event with sub-µA quiescent current. Use Value: Enables >10-year battery life by avoiding leakage-prone discrete solutions and supporting deep-sleep modes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4071BM96 | Same logic function and pinout; narrower 3–15 V supply range; higher quiescent current (5 µA typical) | Not rated for 125°C operation; lacks guaranteed noise margin spec at 15 V | Select when cost sensitivity outweighs extended temperature or noise margin requirements |
| 74HC32DR | Higher speed (tPD ≈ 15 ns), but limited to 2–6 V supply; TTL-compatible inputs only | Requires level translation for 12 V or 15 V systems; unsuitable for direct high-voltage monitoring | Select only for 3.3/5 V digital systems needing faster propagation and lower capacitive loading |
Compared with CD4071BM96 and 74HC32DR, the MC14071BFR2 uniquely supports 18 V operation, guarantees 2.5 V noise margin at full rail, and maintains sub-µA quiescent current - making it the sole choice for high-voltage industrial monitoring and long-life battery applications.

FAQ
What is the maximum supply voltage rating for the MC14071BFR2?
The MC14071BFR2 has an absolute maximum DC supply voltage (VDD) rating of +18.0 V referenced to VSS. Operation beyond this limit risks permanent device damage. The recommended operating range remains 3.0 VDC to 18 VDC, with all electrical characteristics fully specified across this span - including guaranteed noise margins and output drive capability.
Does the MC14071BFR2 require external pull-up or pull-down resistors on unused inputs?
No - the MC14071BFR2 does not require external pull-up or pull-down resistors. Per the datasheet, all unused OR gate inputs must be tied directly to VSS (pin 7) to prevent floating nodes and undefined output states. This internal design requirement stems from the CMOS topology and ensures predictable logic behavior and minimal power consumption.
Is the MC14071BFR2 pin-compatible with CD4071B devices?
Yes, the MC14071BFR2 is explicitly specified as a pin-for-pin replacement for corresponding CD4000-series B-suffix devices, including CD4071B. Its EIAJ SOIC-14 footprint (Case 965-01), pin numbering, and logic function match CD4071B, enabling direct substitution in existing layouts without PCB modification - provided the target application falls within the MC14071BFR2's extended voltage and temperature specifications.
What is the output drive capability of the MC14071BFR2 at 12 V supply?
At VDD = 12 V, the MC14071BFR2 delivers IOL = 3.4 mA (sink) and IOH = –3.4 mA (source) under standard test conditions (VOL = 1.5 V, VOH = 10.5 V). This meets the specification for driving two low-power TTL loads or one low-power Schottky TTL load across the full operating temperature range (–55°C to +125°C), confirming robust interface capability with legacy logic families.
Can the MC14071BFR2 operate reliably at –55°C?
Yes, the MC14071BFR2 is fully characterized and guaranteed to operate from –55°C to +125°C. All key parameters - including propagation delay, output drive, input thresholds, and quiescent current - are specified across this extended industrial temperature range. Its monolithic CMOS construction and double-diode input protection ensure stable performance in cold-storage monitoring, aerospace avionics, and outdoor infrastructure applications.
