Overview
The 4071BDM is a quad 2-input OR gate manufactured by National Semiconductor, now part of Texas Instruments. It belongs to the B Series logic family and utilizes CMOS technology. The device features buffered outputs and is housed in a 24-pin ceramic dual-in-line package (DIP). It operates on a single 5 V supply voltage and supports a wide operating temperature range from -55 °C to +125 °C, suitable for military-grade applications.
Feature Summary
- Quad configuration providing four independent 2-input OR logic functions within a single integrated circuit
- Buffered output structure designed to maintain signal integrity and drive capability across the logic family
- Military-grade temperature rating enabling reliable operation in extreme environmental conditions
Applications
- Logic circuit design requiring multiple OR operations in a compact footprint
- Signal routing and selection networks in electronic systems
- Industrial control interfaces utilizing standard logic families
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the ceramic DIP-24 package matches specific thermal and mechanical requirements. Ensure compliance with relevant military specifications if operating in high-reliability environments. Check for lead-free status and RoHS compliance based on production date codes.
Selection Notes
Select this component when a quad OR gate is required for high-temperature stability. The ceramic package offers superior thermal performance compared to plastic variants. Consider the B Series characteristics for compatibility with existing system logic levels. Evaluate pin-out compatibility if replacing older National Semiconductor designs.
Part Context
This component is part of the extensive National Semiconductor logic portfolio, which has been integrated into Texas Instruments' product line. The 4071 series provides fundamental logic functions widely used in digital electronics. The 'DM' suffix specifically denotes the ceramic dual-in-line package variant, distinguishing it from plastic or other packaging options available in the same logical family.
Replacement Considerations
Compatible substitutes include CD4071BM and UC4071B. Verify pin compatibility and electrical characteristics before substitution. Ensure the replacement device meets the required temperature range and package dimensions.
