4086BDC

Overview

The National Semiconductor 4086BDC is a CMOS multi-function logic gate configured as an AND-OR-INVERT (AOI) device. It integrates one electrical circuit with ten inputs distributed across five distinct input groups, each accommodating two inputs. The component is housed in a 14-pin Ceramic Dual In-Line Package (CDIP) with a standard 0.300-inch (7.62mm) body width. This industrial-grade part is designed for robust digital logic applications requiring complex gating functions within a single integrated circuit package.

Feature Summary

• Configurable AND-OR-INVERT logic structure supporting multiple input combinations
• CMOS technology ensuring low power consumption and high noise immunity
• Hermetically sealed ceramic dual in-line packaging for environmental durability

Applications

• Complex digital logic control systems
• Industrial process automation interfaces
• Military-grade embedded logic circuits

Procurement Notes

Verify the specific suffix 'DC' to confirm the 14-CDIP ceramic package variant. Ensure compatibility with existing board layouts requiring dual in-line form factors. Confirm that the CMOS logic family aligns with system voltage requirements. Check for any specific military qualification markings if operating in harsh environments. Validate pinout consistency with legacy National Semiconductor documentation.

Selection Notes

Select this component when a fixed AND-OR-INVERT function is required without external wiring complexity. The ceramic package is suitable for high-reliability or high-temperature environments where plastic packages may fail. Consider the ten-input capacity for reducing bill-of-materials count in complex gating scenarios. Verify supply chain availability for discontinued National Semiconductor parts through authorized distributors.

Part Context

National Semiconductor, now part of Texas Instruments, historically produced this series of CMOS logic devices. The 4086BDC belongs to the broader family of multi-function gates, offering specialized logic configurations compared to standard NAND or NOR gates. These components were widely used in legacy industrial and military electronics before transitioning to more modern programmable logic solutions.

Replacement Considerations

The 4086BDM is a documented alternative from National Semiconductor, sharing the same AOI logic function but potentially differing in package or qualification details. Cross-reference pinouts and electrical characteristics carefully. No other direct substitutes are confirmed in public documentation.
