100313QI

Overview

The Fairchild Semiconductor 100313QI is a monolithic quad driver belonging to the 100K series. It features two OR and two NOR outputs with a common enable input. The device utilizes ECL logic technology and is housed in a PLCC-28 package. It operates within a voltage compensated range of -4.2V to -5.7V and provides 2000V ESD protection. All inputs include 50 kΩ pull-down resistors, and all outputs are buffered.

Feature Summary

• Monolithic quad driver architecture with integrated OR and NOR logic functions
• Common enable input allows driving multiple transmission lines when data inputs are unused
• Buffered inputs minimize loading effects on preceding circuit stages
• High electrostatic discharge (ESD) immunity rating for robust signal integrity

Applications

• Low power line driving applications requiring reduced energy consumption
• Digital systems utilizing ECL logic families for high-speed processing
• Circuit designs requiring pin-compatible upgrades from legacy 100112 or 100113 drivers

Procurement Notes

Verify the specific suffix 'QI' against official manufacturer documentation to confirm industrial grade temperature range availability, as standard variants may differ. Confirm package type compatibility during integration. Ensure supply chain sources provide authentic components from Fairchild or its successor entities to guarantee performance specifications are met.

Selection Notes

Select this component for designs prioritizing low power dissipation relative to previous generation drivers. The device offers a direct functional replacement for older models while providing enhanced ESD protection. Consider the specific output logic configuration (OR/NOR) and the necessity of buffered inputs when evaluating system interface requirements.

Part Context

This part belongs to the 100K series of ECL logic devices manufactured by Fairchild Semiconductor. The series is characterized by high-speed operation and low power consumption. The 100313 variant specifically addresses applications needing quad buffering with logical inversion capabilities, serving as a specialized driver within digital communication and processing architectures.

Replacement Considerations

The datasheet confirms pin and function compatibility with the 100113 and 100112 parts. Designers can substitute these legacy components directly without modifying the board layout, provided the power supply and thermal constraints remain within the specified operating ranges.
