CD4071 Quad 2‑Input OR Gate IC ⚡

The CD4071 is a quad 2‑input OR gate integrated circuit in a DIP‑14 package, designed for reliable operation across a wide supply range. Built on the CMOS 4000B series process, it offers high-voltage capability, low quiescent current, and symmetrical output drive. Ideal for digital logic designs in Arduino, Raspberry Pi, and other microcontroller-based projects, as well as professional embedded systems and industrial control.

✨ Key Features

• High-voltage CMOS design with up to 20 V rating (absolute maximum), providing excellent system design flexibility.
• Medium-speed operation: typically up to ~10 MHz at VDD − VSS = 10 V (application-dependent).
• Standardized, symmetrical output characteristics for balanced rise/fall times and predictable drive capability.
• Fully tested quiescent current at 20 V for dependable low-power behavior.
• Parametric ratings specified at 5 V, 10 V, and 15 V supplies.
• Compliant with JEDEC Tentative Standard No. 13B for “B” Series CMOS devices.

📐 Technical Specifications

• Function: Quad 2‑input OR gate (4 independent gates)
• Package: DIP‑14
• Operating temperature: −55 °C to +125 °C
• Supply voltage (VDD): 3.0 V to 18 V (absolute maximum rating up to 20 V)
• Number of gates: 4
• Inputs per gate: 2

🧰 Typical Applications

• Digital logic design: implementing combinational logic, gating, and logic-level conditioning
• Signal processing and control logic in embedded systems
• Power management logic enable/OR-ing
• Consumer electronics and industrial automation control paths
• Prototyping with electronics components and modules on breadboards

🔌 Integration Notes for Arduino & Raspberry Pi

• Operates from 3.3 V or 5 V rails for straightforward use with Raspberry Pi and Arduino systems.
• Inputs are CMOS‑level (typical VIH ≈ 0.5 × VDD). Ensure driving signals meet the required thresholds for the selected voltage.
• When powered at 3.3 V, do not drive inputs above VDD (not 5 V tolerant). Use level shifting if needed.
• Prevent floating inputs—use pull-ups or pull-downs for stable logic states.
