CY74FCT2240CTSOCE4

Overview

The CY74FCT2240CTSOCE4 is an octal buffer and line driver manufactured by Texas Instruments. It belongs to the FCT logic series and utilizes CMOS technology. The device features eight non-inverting input lines and three-state outputs, housed in a 20-SOIC package. It operates within a supply voltage range of 4.75 V to 5.25 V. Key electrical parameters include a propagation delay of 4.1 ns at 5 V, high-level output current of -15 mA, and low-level output current of 12 mA. The component supports surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides octal buffering with non-inverting signal transmission for data integrity
• Features three-state outputs to facilitate bus-oriented memory and circuit driving
• Utilizes advanced CMOS technology for low power consumption and high speed

Applications

• Bus-oriented memory applications requiring signal buffering
• Clock drivers for high-speed digital systems
• Circuit driving where multiple loads must be managed via three-state control

Procurement Notes

Verify the complete part number including suffixes such as E4, which indicates lead-free status and RoHS compliance. Confirm the package type is SOIC-20 and check the lifecycle status, as this specific variant may be obsolete. Ensure the supplier provides official datasheets matching the Texas Instruments specification for the CY74FCT2240T series to guarantee functional compatibility.

Selection Notes

Select this component when an octal buffer with three-state capability is required for 5V logic systems. It is suitable for designs needing low propagation delay and high drive strength. Consider the 20-SOIC package constraints and thermal requirements for the -40°C to +85°C operating range. Verify that the application does not require inverted logic, as this device is non-inverting.

Part Context

This component is part of the CY74FCT2240T family of buffers and line drivers. It shares the FCT logic architecture with other devices like the CY74FCT2244 and CY74FCT240. The 'E4' suffix denotes environmental compliance. It serves as a standard interface solution for connecting microprocessors to memory or peripheral devices in industrial and commercial electronics.

Replacement Considerations

Check for direct substitutes within the same FCT family, such as the CY74FCT2244CTSOC for similar buffering needs. Verify pinout compatibility before swapping with other octal buffers. Ensure any replacement maintains the 3-state output functionality and 5V operation requirements.
