CY74FCT240CTSOCT

Overview

The CY74FCT240CTSOCT is an octal buffer and line driver manufactured by Texas Instruments, belonging to the FCT logic series. It features two functional blocks of four bits each, providing inverted outputs with three-state capability. The device operates within a supply voltage range of 4.75 V to 5.25 V and utilizes CMOS technology. It is housed in a 20-pin SOIC package with a width of 7.50 mm. Key electrical parameters include a propagation delay of 4.8 ns at 5 V, high-level output current of -32 mA, and low-level output current of 64 mA. The component supports surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides eight inverted outputs with three-state control for bus driving applications
• Utilizes Fast CMOS (FCT) technology for high-speed signal buffering
• Features robust drive capability with specified high and low-level output currents

Applications

• Bus-oriented memory and address drivers
• Clock drivers and buffer circuits
• High-speed data transmission lines

Procurement Notes

Verify the manufacturer designation carefully, as this part number is associated with Texas Instruments despite the query specifying Cypress Semiconductor Corp. Confirm the specific suffix 'CTSOCT' corresponds to the standard SOIC-20 package and reel packaging details. Ensure compatibility with existing design specifications regarding the FCT logic family characteristics before procurement.

Selection Notes

Select this component when designing systems requiring octal buffering with inverted logic and three-state output control. It is suitable for applications demanding fast switching speeds within a 5V logic environment. Consider the SOIC-20 package constraints and thermal requirements for the -40°C to +85°C operating range during PCB layout and system integration planning.

Part Context

This component is part of the broader 74FCT series of high-speed CMOS logic devices produced by Texas Instruments. While originally developed under the Cypress Semiconductor brand prior to its acquisition by Infineon and subsequent licensing or manufacturing transitions, current documentation and availability are primarily linked to Texas Instruments. It serves as a standard solution for digital interface buffering in legacy and industrial electronic designs.

Replacement Considerations

Publicly confirmed substitute part numbers include CY74FCT240ATSOCT and 74FCT240CTSOG. Verify pinout compatibility and electrical specifications against these alternatives to ensure seamless integration into existing circuit designs without modification.
