100314QCX

Overview

The Fairchild Semiconductor 100314QCX is a low-power quint differential line receiver. It integrates five independent receivers within a single package, designed for high-speed data transmission applications. The device operates with a supply voltage range of 3.0 V to 5.25 V and features ECL-compatible inputs. Key electrical parameters include a typical propagation delay of 1.8 ns and a skew of 0.6 ns. The output stage provides differential currents suitable for driving 100-ohm transmission lines. The component is housed in an 8-pin SOIC surface-mount package.

Feature Summary

• Integrates five independent differential receivers for compact system design
• ECL-compatible input logic levels ensure compatibility with existing emitter-coupled logic systems
• Low power consumption characteristics optimize thermal performance in dense circuits
• High-speed operation supports data rates up to 155 Mbps

Applications

• SONET/SDH network interface cards
• Asynchronous Transfer Mode (ATM) switching equipment
• High-speed serial communication backplanes
• Optical receiver modules

Procurement Notes

Verify the specific suffix 'QCX' against current ON Semiconductor catalogs, as Fairchild Semiconductor product lines have been integrated into ON Semiconductor. Confirm RoHS compliance status and lead times directly with authorized distributors, as legacy part numbers may have superseded versions or obsolescence notices.

Selection Notes

Select this component when multiple differential channels are required in a space-constrained environment. Ensure the system operates within the specified 3.0 V to 5.25 V supply range. Verify that the 155 Mbps data rate requirement aligns with the application's signal integrity constraints and termination requirements.

Part Context

The 100314 series belongs to the family of low-power differential line receivers originally developed by National Semiconductor and later produced by Fairchild Semiconductor. These devices were widely used in telecommunications infrastructure before being phased out or replaced by newer generations of transceivers offering higher speeds and lower power profiles.

Replacement Considerations

Check for direct pin-to-pin replacements such as the MC10E116 or SY10E116. Newer alternatives from ON Semiconductor or other manufacturers should be evaluated for speed and power compatibility.
