What are the key features of CD4071BNS?
- Quad 2-input OR gate provides 4 independent logic functions in a single package, reducing component count in combinational logic designs
- Wide 3 V to 18 V supply voltage range enables compatibility with TTL, CMOS, and battery-powered 9 V to 12 V systems
- Ultra-low quiescent current CMOS technology minimizes power consumption in always-on control logic and portable equipment
What is CD4071BNS used for?
The CD4071BNS is used in combinational logic designs, alarm circuits, and signal combining applications where OR gate functions are required across a wide supply voltage range from 3 V to 18 V. Its quad configuration allows multiple logic combining operations within a single package, simplifying PCB layout in microcontroller interface circuits and industrial control panels. The CMOS architecture's low power consumption makes it suitable for battery-powered remote sensors, security alarms, and low-duty-cycle embedded logic.

Frequently Asked Questions
What supply voltage range does the CD4071BNS support, and which logic families can it interface with directly?
The CD4071BNS operates from 3 V to 18 V supply voltage, making it compatible with TTL logic at 5 V, CMOS logic at 3.3 V to 5 V, and 9 V or 12 V battery-powered systems without level translation. At 5 V supply, its output logic levels are compatible with standard 74HC and 74HCT inputs. The 18 V maximum supply rating also allows direct use in 12 V automotive control logic and industrial sensor conditioning circuits where supply voltages exceed standard digital logic rails.
How does having 4 OR gates in a single CD4071BNS package benefit a compact alarm circuit design?
A security alarm system typically combines signals from multiple sensors — door contacts, motion detectors, glass-break sensors — using OR logic to trigger a single alarm output. The CD4071BNS provides all 4 OR gates needed to combine up to 4 sensor pairs in one package, eliminating 3 additional ICs compared to single-gate alternatives. Its near-zero quiescent current draw at 3 V to 5 V keeps the standby power budget under 1 µA, critical for battery-backed alarm panels that must run for months without power interruption.
When should a designer choose CD4071BNS over a 74HC32 quad OR gate for a 12 V industrial logic circuit?
The CD4071BNS is the correct choice when the logic supply voltage exceeds 5.5 V, since the 74HC32 is limited to a 2 V to 5.5 V supply range. For 9 V or 12 V industrial control circuits — such as PLC input modules or relay driver logic — the CD4071BNS operates natively at those voltages, while the 74HC32 requires a separate 5 V regulator. The CD4000B series CMOS also tolerates slower input signal edges and higher input capacitance typical in industrial cable-connected systems without oscillation issues.
