CY74FCT240ATSOC

Overview

The CY74FCT240ATSOC is an octal buffer and line driver featuring three-state outputs, manufactured by Texas Instruments. It operates within a supply voltage range of 4.75 V to 5.25 V and utilizes CMOS logic technology. The device provides high drive capability with a low-level output current of 64 mA and a high-level output current of -32 mA. It exhibits a propagation delay of 4.8 ns at 5 V and maintains a maximum operating temperature of +85 C. The component is housed in a 20-pin SOIC package.

Feature Summary

• Octal configuration providing eight independent signal paths for data buffering
• Three-state output architecture enabling bus-oriented system designs
• Inverting polarity functionality for signal phase adjustment

Applications

• Bus-oriented memory systems
• Clock drivers
• Buffering applications requiring high drive strength

Procurement Notes

Verify the specific suffix 'SO' indicates the SOIC-20 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supply voltage remains strictly within the 4.75 V to 5.25 V operational limits to maintain specified electrical performance and reliability standards.

Selection Notes

Select this component for designs requiring eight-channel inversion with significant current drive capabilities. The FCT series offers speed comparable to LS TTL while maintaining CMOS power efficiency. Consider the SOIC-20 footprint constraints during PCB layout planning to ensure adequate thermal dissipation and mechanical stability for surface-mount assembly processes.

Part Context

This part belongs to the CY74FCT240T series of logic integrated circuits. It serves as a high-speed buffer solution within the broader family of FCT logic devices. The component is designed to interface between microprocessors and peripheral devices, ensuring signal integrity across digital buses in industrial and commercial electronic equipment.

Replacement Considerations

The CY74FCT240ATQCT is a verified alternative offering identical logical functions in a QSOP-20 package. Designers must verify pin compatibility and physical footprint differences before substituting components to ensure proper board integration.
