100313FM-MLS

Overview

The 100313FM-MLS is a high-speed ECL inverter and buffer from the 100K series, manufactured by National Semiconductor. It contains four independent logic functions with one input per function. The device utilizes an ECL technology node and is housed in a 24-terminal ceramic glass-sealed flatpack (CQFP/CERPACK) package. Key electrical characteristics include a propagation delay of 2.3 ns. It operates within a military temperature range of -55 °C to +125 °C.

Feature Summary

• High-speed ECL logic performance with 2.3 ns propagation delay
• Military-grade reliability with extended temperature range capability
• Hermetically sealed ceramic construction for harsh environment durability

Applications

• High-speed digital signal processing systems
• Military aerospace communication equipment
• Radar and electronic warfare subsystems

Procurement Notes

Verify the specific manufacturer source, as Rochester Electronics may distribute this part originally designed by National Semiconductor. Confirm the exact package variant (CQFP vs CERPACK) matches the mechanical drawing requirements. Ensure the ECL voltage levels align with the system design specifications before integration.

Selection Notes

Select this component when high-speed switching speeds are critical and ECL logic families are required. The military temperature rating makes it suitable for extreme environments where standard commercial parts would fail. Consider the 24-pin ceramic package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the National Semiconductor 100K series, a family of high-speed ECL logic devices. These components were widely used in legacy high-performance computing and telecommunications infrastructure before being superseded by faster CMOS technologies. The 100313FM-MLS specifically provides buffered inversion capabilities within this high-speed ecosystem.
