CD4081BCN

Inverter Gates Overview

The CD4081BCN is a monolithic CMOS integrated circuit containing four independent 2-input AND gates. It operates within a DC supply voltage range of 3V to 15V and supports an operating temperature range from -55°C to +125°C. The device features buffered outputs with symmetrical source and sink current capabilities, conforming to standard B series output drive specifications. It provides low power TTL compatibility, allowing a fan-out of two driving 74L logic or one driving 74LS logic. Input protection against static discharge is included via diodes connected to VDD and VSS.

Inverter Gates Feature Summary

• Monolithic complementary MOS construction utilizing N- and P-channel enhancement mode transistors for equal source and sink current capabilities.
• Buffered outputs designed to improve transfer characteristics by providing very high gain.
• Low power consumption ensuring compatibility with TTL logic families.
• All inputs protected against static discharge using internal diodes.

Inverter Gates Applications

• Digital logic circuits requiring quad 2-input AND functionality
• Systems interfacing between CMOS and TTL logic levels
• General-purpose buffering applications in electronic designs

Inverter Gates Procurement Notes

Verify the ordering code matches CD4081BCN to ensure the correct 14-Lead Plastic Dual-In-Line Package (PDIP). Confirm that the required suffix 'X' is omitted if tape and reel packaging is not needed. Ensure the component meets the specified JEDEC MS-001 package dimensions for your board layout requirements.

Inverter Gates Selection Notes

Select this component when four independent 2-input AND gates are required in a single package. It is suitable for designs needing operation across a wide temperature range and compatibility with both 74L and 74LS logic families. Consider the PDIP-14 package constraints for through-hole mounting versus surface mount alternatives like the BCM variant.

Inverter Gates Part Context

This device belongs to the Quad 2-Input AND Buffered B Series Gate family. It is manufactured by Fairchild Semiconductor Corporation and conforms to standard B series output drive specifications. The part is distinct from the CD4071BC, which provides OR gate functionality instead of AND gates.

Inverter Gates Replacement Considerations

CD4081BCM: Same logical function but in SOIC-14 package.

Inverter Gates FAQ

What is the maximum input leakage current specification?

The maximum input leakage current is 1 µA at 15V over the full temperature range.

How does the device handle unused inputs?

While not explicitly detailed in the provided text, standard practice for CMOS devices with input protection diodes suggests connecting unused inputs to VDD, VSS, or another input to prevent damage.
