The Texas Instruments CD4071BM is a CMOS quad 2-input OR gate IC, designed explicitly for reliable logical operations in medium-speed digital circuits. Packaged in a 14‑pin SOIC (Surface Mount, SOIC‑14) form factor, it suits both compact PCB designs and industrial-grade systems.

Core Features and Benefits Include

  • Supply Voltage Range: 3 V to 18 V, offering versatile use across 5 V, 10 V, and 15 V logic levels.
  • Quiescent Current: Extremely low power draw, typically 1 µA max.
  • Output Drive (High/Low): Approximately 3.4 mA for both states.
  • Propagation Delay: Around 60–90 ns depending on load and voltage (e.g., ~90 ns @ 15 V, 50 pF).
  • Operating Temperature: Wide industrial-grade range –55 °C to +125 °C.
  • Input Logic Thresholds: High: 3.5 V–11 V; Low: 1.5 V–4 V.
  • Packaging Status: Marked as Obsolete by some distributors, although TI lists an active variant, CD4071BM96, for high-volume reel orders.

Why Choose this Product?

Engineers working on industrial control systems, avionics, or legacy digital hardware will value the CD4071BM's CMOS efficiency, wide supply voltage tolerances, and robust thermal performance. Its low quiescent current and symmetrical output characteristics make it ideal for battery-powered and noise-sensitive applications. The SOIC-14 package also supports automated manufacturing, offering cost-effective assembly for large-scale deployments.
