100314W-QMLV

Overview

The National Semiconductor 100314W-QMLV is a low-power quint differential line receiver designed for high-speed digital communication. It operates within the ECL100K logic family, providing five independent receivers in a single package. The device supports a supply voltage range of -5.2V to -5.7V and features a typical propagation delay of 1.8ns at VCC = -5.2V. It is qualified under the QMLV standard for military and aerospace applications, ensuring reliability across an extended temperature range of -55°C to +125°C.

Feature Summary

• Five independent differential line receivers integrated into a single ceramic package
• Qualified under QMLV standards for radiation hardness and long-term stability
• Low power consumption optimized for ECL100K logic family operation
• High-speed signal transmission with typical propagation delay of 1.8ns

Applications

• Military satellite communication systems requiring radiation-hardened components
• Aerospace data bus interfaces demanding high reliability and low power
• High-speed digital communication links in harsh environmental conditions
• Avionics systems utilizing ECL logic families for critical data transmission

Procurement Notes

Verify QMLV certification status and lot traceability documentation upon receipt. Ensure storage conditions comply with moisture sensitivity levels for ceramic packages. Confirm that the ordering suffix matches the required radiation hardness and temperature grade specifications for your specific application environment.

Selection Notes

Select this component when a quint differential receiver is needed within the ECL100K family. Consider the QMLV qualification if the application requires military-grade reliability or radiation tolerance. Evaluate the -5.2V to -5.7V supply requirement against your system's power architecture before integration.

Part Context

This part belongs to the National Semiconductor 100314 series of low-power quint differential line receivers. The QMLV suffix indicates qualification under the Military Standard for Microcircuit Devices, specifically Level V, which includes enhanced testing for radiation hardness and failure rate monitoring compared to commercial variants.

Replacement Considerations

Direct replacements include the MN100314W-QMLV from Texas Instruments or the SY10E116 from Micrel, provided they meet the same QMLV qualification requirements. Verify pin compatibility and electrical parameters such as propagation delay and supply current before substitution.
