100314QC

Overview

The Fairchild Semiconductor 100314QC is a low-power quint differential line receiver belonging to the ECL logic family. It integrates five independent receivers within a single package, designed for high-speed data transmission applications requiring low power consumption. The device operates with true outputs and utilizes an ECL-compatible input interface. It is housed in a 28-pin plastic leaded chip carrier (LCC-28) package, specifically identified as MO-047 with dimensions of 0.450 x 0.450 inches. The component supports a maximum operating temperature of 85 °C and features a propagation delay of 6.6 ns.

Feature Summary

• Integrates five independent differential line receivers for multi-channel signal processing
• Optimized for low-power operation within the ECL logic family
• Provides true output polarity for direct interfacing with downstream logic circuits

Applications

• High-speed serial communication interfaces
• Data acquisition systems requiring multiple differential inputs
• Telecommunications equipment signal conditioning

Part Context

This component is part of Fairchild's extensive portfolio of ECL-based logic devices, which were widely used in high-performance computing and networking infrastructure before the industry transitioned to faster CMOS technologies. The 'QC' suffix typically denotes a specific tape-and-reel packaging variant or quality certification level within the manufacturer's cataloging system for this LCC-28 form factor.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should verify pin compatibility and electrical characteristics against equivalents such as the MC10E116 or SY10E116, noting that these may require voltage level adjustments due to ECL biasing requirements.
