40097BDMQB

Overview

The Fairchild Semiconductor 40097BDMQB is a military-grade integrated circuit functioning as a hex non-inverting buffer with three-state outputs. It features two enable inputs to control the output state, allowing for high-impedance isolation when disabled. The device is housed in a 16-pin Ceramic Dual In-Line Package (CDIP), designed for through-hole mounting. This component is part of the 4000 series logic family, providing robust signal buffering capabilities suitable for demanding environments requiring strict quality and reliability standards.

Feature Summary

• Military-grade qualification ensuring high reliability and performance under extreme conditions
• Hex non-inverting buffer architecture with six independent logic channels
• Three-state output capability controlled by dedicated enable inputs for bus isolation
• Ceramic Dual In-Line Package (CDIP) construction for enhanced durability

Applications

• Military avionics systems requiring qualified logic components
• High-reliability industrial control equipment
• Aerospace communication bus interfaces
• Defense electronics signal conditioning circuits

Procurement Notes

Verify that the supplier provides documentation confirming the specific military grade designation associated with the 'M' suffix in the part number. Ensure the ceramic package integrity is intact upon receipt, as CDIP packages are sensitive to mechanical stress during handling and installation. Confirm compatibility with existing board layouts for 16-CDIP footprints.

Selection Notes

Select this component when a non-inverting buffer with tri-state functionality is required in a ruggedized application. The 16-CDIP package is necessary for applications where hermetic sealing or superior thermal/mechanical stability is mandated over standard plastic packages. Consider the pinout compatibility if replacing older equivalents within the same logic family.

Part Context

This part belongs to the 4000 series of CMOS logic devices, originally developed by Fairchild Semiconductor. The 40097B variant specifically denotes a hex buffer with three-state outputs. The 'DMQB' suffix indicates the military grade qualification and the ceramic dual in-line package type, distinguishing it from commercial plastic variants.

Replacement Considerations

Direct substitutes include other manufacturers' military-grade hex buffers with three-state outputs in 16-CDIP packages, such as those from Microchip or NXP, provided they match the pinout and electrical characteristics of the HEF40097B specification.
