54F00FMQB

Overview

The 54F00FMQB is a quad 2-input NAND gate from the F/FAST series, manufactured by National Semiconductor. It utilizes TTL logic technology and operates on a 5 V supply voltage. The device features a ceramic flatpack package with 14 terminals, designed for high-temperature environments ranging from -55 °C to 125 °C. It provides 4000V ESD protection and supports bidirectional data flow with independent control capabilities.

Feature Summary

• Quad 2-input NAND gate configuration within the F/FAST series
• Robust 4000V electrostatic discharge (ESD) protection
• High-temperature operational capability up to 125 °C
• Ceramic flatpack construction for durability

Applications

• Digital logic circuit design requiring NAND functionality
• Industrial control systems operating in high-temperature environments
• Military-grade electronic assemblies requiring radiation-hardened or high-reliability components

Procurement Notes

Verify the specific ordering suffix FMQB against official National Semiconductor documentation to confirm the exact package variant and temperature grade. Ensure compliance with RoHS directives if required, as historical data indicates non-compliance for some variants. Cross-reference the JESD-30 code R-GDFP-F14 to validate the physical footprint and terminal arrangement before integration into PCB layouts.

Selection Notes

Select this component when a quad NAND gate with high-speed F/FAST performance is needed in a ceramic flatpack format. It is suitable for applications demanding high thermal stability and robust ESD protection. Compare pin compatibility with standard SOIC packages if space constraints exist, noting the distinct flatpack geometry. Verify that the 5 V logic level aligns with the system's power supply requirements.

Part Context

This part belongs to the National Semiconductor F/FAST logic family, known for high-speed operation. The 54F00 series specifically provides NAND gates. The FMQB designation typically indicates a military-grade or high-reliability ceramic flatpack version, distinguishing it from commercial plastic packages. It serves as a fundamental building block for complex digital logic circuits.

Replacement Considerations

Check for direct equivalents such as the 54F00FM or other F/FAST series NAND gates from Texas Instruments or National Semiconductor. Verify pinout compatibility and electrical characteristics like propagation delay and output current before substitution.
