100313QC

Overview

The Fairchild Semiconductor 100313QC is a monolithic quad driver belonging to the 100K ECL series. It features two OR and two NOR outputs with a common enable input. The device operates within a voltage compensated range of -4.2V to -5.7V. It includes 50 kΩ pull-down resistors on all inputs and buffered outputs. The component provides 2000V ESD protection and offers a 50% power reduction compared to the 100113 model. It utilizes a PLCC-28 package.

Feature Summary

• Integrates two OR and two NOR functions with a shared enable control
• Provides significant power efficiency improvements over legacy counterparts
• Features high electrostatic discharge robustness for signal integrity
• Includes internal pull-down resistors to minimize input loading

Applications

• High-speed digital line driving applications
• ECL logic circuit implementation
• Systems requiring low power dissipation in dense packaging

Procurement Notes

Verify the specific suffix 'QC' against the manufacturer's current datasheet to confirm industrial grade temperature availability, as this designation may apply only to the PLCC package variant. Ensure the source document explicitly lists the 100313QC part number rather than the generic 100313. Confirm RoHS compliance status if required by your assembly specifications, as older ECL components may vary in environmental certification.

Selection Notes

Select this component when a low-power ECL quad driver with mixed OR/NOR functionality is required. It serves as a direct pin-compatible replacement for the 100113 and 100112 models while offering reduced power consumption. Consider the PLCC package constraint for industrial temperature ranges. Verify that the system voltage aligns with the specified -4.2V to -5.7V operating range.

Part Context

This device is part of the National Semiconductor/Fairchild 100K ECL family, designed for high-speed digital applications. The 100313 series specifically addresses the need for lower power dissipation in line driver circuits. The QC suffix typically denotes specific manufacturing or qualification standards within the 100K product line, often associated with the plastic leaded chip carrier package configuration.

Replacement Considerations

The 100313QC is pin and function compatible with the 100113 and 100112 models. Cross-reference with National Semiconductor equivalents such as the 100313D or 100313F if sourcing from different distributors. Ensure the replacement supports the required ECL voltage levels and output buffering characteristics.
