CY74FCT240CTSOCE4

Overview

The CY74FCT240CTSOCE4 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 inputs and three-state outputs with inverting polarity. It operates within a supply voltage range of 4.75 V to 5.25 V. The component is housed in a 20-pin SOIC package designed for surface mount installation. It supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Provides octal buffering with three-state output capability for bus interfacing
• Features inverting logic polarity for signal inversion applications
• Utilizes CMOS technology within the FCT logic family for performance

Applications

• Memory mapping systems
• Clock drivers
• Buffering registers

Procurement Notes

Verify the specific suffix E4 indicates lead-free compliance and RoHS status. Confirm the package type matches the required PCB footprint. Check current availability as this part may be discontinued or superseded by newer revisions. Ensure the operating temperature range meets system requirements.

Selection Notes

Select this component for applications requiring octal buffering with inverting functionality. Consider the FCT series compatibility with TTL inputs. Evaluate the package size constraints against the available SOIC-20 footprint. Verify power supply stability within the specified voltage limits.

Part Context

This part is part of the 74FCT240 family of octal buffers. It serves as a digital logic interface component. The E4 suffix typically denotes environmental compliance. It is distinct from non-inverting variants like the 74FCT244.

Replacement Considerations
